CAUTION!

INTRODUCTION This unit (see Fig. 1) is a fully self- contained, combination Category I gas heating/electric heating and cooling unit designed for outdoor installation (See Fig. 2 and 3 for unit dimensions). All unit sizes have return and discharge openings for both horizontal and downflow configurations, and are factory shipped with all downflow duct openings covered. Units may be installed either on a rooftop, or on a cement slab (See Fig. 4 for roof curb dimensions). In gas heating mode, this unit is designed for a minimum continuous return- air temperature of 55_F (13_C) db and a maximum continuous return- air temperature of 80_F (27_C) db. Failure to follow these return- air temperature limits may affect reliability of heat exchangers, motors, and other components. Models with an N in the fifth position of the model number are dedicated Low NOx units designed for California installations. These models meet the California maximum oxides of nitrogen (NOx) emissions requirements of 40 nanograms/joule or less as shipped from the factory and must be installed in California Air Quality Management Districts or any other regions in North America where a Low NOx rule exists.

RECEIVING AND INSTALLATION Step 1 Check Equipment IDENTIFY UNIT

The unit model number and serial number are stamped on the unit information plate. Check this information against shipping papers.

INSPECT SHIPMENT

Inspect for shipping damage before removing packaging materials. If unit appears to be damaged or is torn loose from its anchorage, have it examined by transportation inspectors before removal. Forward claim papers directly to transportation company. Manufacturer is not responsible for any damage incurred in transit. Check all items against shipping list. Immediately notify the nearest equipment distribution office if any item is missing. To prevent loss or damage, leave all parts in original packages until installation.

If the unit is to be mounted on a curb in a downflow application, review Step 9 to determine which method is to be used to remove the downflow panels before rigging and lifting into place. The panel removal process may require the unit to be on the ground.

Step 2 Provide Unit Support For hurricane tie downs, contact distributor for details and PE (Professional Engineering) Certificate if required.

ROOF CURB

Install accessory roof curb in accordance with instructions shipped with curb (See Fig. 4). Install insulation, cant strips, roofing, and flashing. Ductwork must be attached to curb.

IMPORTANT: The gasketing of the unit to the roof curb is critical for a water tight seal. Install gasketing material supplied with the roof curb. Improperly applied gasketing also can result in air leaks and poor unit performance.

Curb should be level to within 1/4 in. (6 mm). This is necessary for unit drain to function properly. Refer to accessory roof curb installation instructions for additional information as required.

Installation on older G series roof curbs.

Two accessory kits are available to aid in installing a new G series unit on an old G roof curb.

1. Accessory kit number CPADCURB001A00, (small chassis) and accessory kit number CPADCURB002A00, (large chassis) includes roof curb adapter and gaskets for the perimeter seal and duct openings. No additional modifications to the curb are required when using this kit.

2. An alternative to the adapter curb is to modify the existing curb by removing the outer horizontal flange and use accessory kit number CPGSKTKIT001A00 which includes spacer blocks (for easy alignment to existing curb) and gaskets for the perimeter seal and duct openings. This kit is used when existing curb is modified by removing outer horizontal flange.

UNIT/STRUCTURAL DAMAGE HAZARD

Failure to follow this caution may result in property damage.

Ensure there is sufficient clearance for saw blade when cutting the outer horizontal flange of the roof curb so there is no damage to the roof or flashing.

Step 3 Field Fabricate Ductwork Secure all ducts to roof curb and building structure on vertical discharge units. Do not connect ductwork to unit. For horizontal applications, unit is provided with flanges on the horizontal openings. All ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.

If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes.

See unit rating plate for any required clearances around ductwork. Cabinet return- air static shall not exceed - .25 IN. W.C.

Step 4 Provide Clearances The required minimum operating and service clearances are shown in Fig. 2 and 3.

IMPORTANT: Do not restrict outdoor airflow. An air restriction at either the outdoor- air inlet or the fan discharge may be detrimental to compressor life.

The condenser fan pulls air through the condenser coil and discharges it through the top grille. Be sure that the fan discharge does not recirculate to the condenser coil. Do not locate the unit in either a corner or under an overhead obstruction. The minimum clearance under a partial overhang (such as a normal house overhang) is 48- in. (1219 mm) above the unit top. The maximum horizontal extension of a partial overhang must not exceed 48- in. (1219 mm).

Do not place the unit where water, ice, or snow from an overhang or roof will damage or flood the unit. Do not install the unit on carpeting or other combustible materials. The unit may be installed on Class A, B, or C roof covering materials. Slab mounted units should be at least 2- in. (51 mm) above the highest expected water and runoff levels. Do not use unit if it has been under water.

Step 5 Rig and Place Unit

PERSONAL INJURY OR PROPERTY DAMAGE HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

When installing the unit on a rooftop, be sure the roof will support the additional weight.

! WARNING

Rigging and handling of this equipment can be hazardous for many reasons due to the installation location (roofs, elevated structures, etc.).

Only trained, qualified crane operators and ground support staff should handle and install this equipment.

When working with this equipment, observe precautions in the literature, on tags, stickers, and labels attached to the equipment, and any other safety precautions that might apply.

Training for operators of the lifting equipment should include, but not be limited to, the following:

1. Application of the lifter to the load, and adjustment of the lifts to adapt to various sizes or kinds of loads.

2. Instruction in any special operation or precaution.

3. Condition of the load as it relates to operation of the lifting kit, such as balance, temperature, etc.

Follow all applicable safety codes. Wear safety shoes and work gloves.

Inspection Prior to initial use, and at monthly intervals, all rigging shackles, clevis pins, and straps should be visually inspected for any damage, evidence of wear, structural deformation, or cracks. Particular attention should be paid to excessive wear at hoist

48 EZ -- A

7

hooking points and load support areas. Materials showing any kind of wear in these areas must not be used and should be discarded.

UNIT FALLING HAZARD

Failure to follow this warning could result in personal injury or death.

Never stand beneath rigged units or lift over people.

! WARNING

PROPERTY DAMAGE HAZARD

Failure to follow this warning could result in personal injury/death or property damage.

When straps are taut, the clevis should be a minimum of 36 in. (914 mm) above the unit top cover.

! WARNING

Rigging/Lifting of Unit (See Fig. 5) Lifting holes are provided in base rails as shown in Fig. 2 and 3.

1. Leave top shipping skid on the unit for use as a spreader bar to prevent the rigging straps from damaging the unit. If the skid is not available, use a spreader bar of sufficient length to protect the unit from damage.

2. Attach shackles, clevis pins, and straps to the base rails of the unit. Be sure materials are rated to hold the weight of the unit (See Fig. 5).

3. Attach a clevis of sufficient strength in the middle of the straps. Adjust the clevis location to ensure unit is lifted level with the ground.

After the unit is placed on the roof curb or mounting pad, remove the top skid.

Step 6 Connect Condensate Drain NOTE: When installing condensate drain connection be sure to comply with local codes and restrictions.

This model disposes of condensate water through a 3/4 in. NPT fitting which exits through the compressor access panel (See Fig. 2 and 3 for location).

Condensate water can be drained directly onto the roof in rooftop installations (where permitted) or onto a gravel apron in ground level installations. Install a field- supplied condensate trap at end of condensate connection to ensure proper drainage. Make sure that the outlet of the trap is at least 1 in. (25 mm) lower than the drain- pan condensate connection to prevent the pan from overflowing (See Fig. 6). Prime the trap with water. When using a gravel apron, make sure it slopes away from the unit.

If the installation requires draining the condensate water away from the unit, install a 2- in. (51 mm) trap at the condensate connection to ensure proper drainage (See Fig. 6). Make sure that the outlet of the trap is at least 1 in. (25 mm) lower than the drain- pan condensate connection. This prevents the pan from overflowing.

Prime the trap with water. Connect a drain tube - using a minimum of 3/4- in. PVC or 3/4- in. copper pipe (all field- supplied) - at the outlet end of the 2- in. (51 mm) trap. Do not undersize the tube. Pitch the drain tube downward at a slope of at least 1- in. (25 mm) for every 10 ft (3 m) of horizontal run. Be sure to check the drain tube for leaks.

Step 7 Install Flue Hood The flue assembly is secured and shipped in the return air duct. Remove duct cover to locate the assembly (See Fig. 8).

NOTE: Dedicated low NOx models MUST be installed in California Air Quality Management Districts where a Low NOx rule exists.

These models meet the California maximum oxides of nitrogen (NOx) emissions requirements of 40 nanograms/joule or less as shipped from the factory.

NOTE: Low NOx requirements apply only to natural gas installations.

CARBONMONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury or death.

The venting system is designed to ensure proper venting. The flue hood assembly must be installed as indicted in this section of the unit installation instructions.

! WARNING

Install the flue hood as follows:

1. This installation must conform with local building codes and with the National Fuel Gas Code (NFGC) NFPA 54 / ANSI Z223.1, (in Canada, CAN/CGA B149.1, and B149.2) latest revision. Refer to Provincial and local plumbing or wastewater codes and other applicable local codes.

2. Remove flue hood from shipping location (inside the return section of the blower compartment- see Fig. 8). Remove the return duct cover to locate the flue hood. Place flue hood assembly over flue panel. Orient screw holes in flue hood with holes in the flue panel.

3. Secure flue hood to flue panel by inserting a single screw on the top flange and the bottom flange of the hood.

Step 8 Install Gas Piping The gas supply pipe enters the unit through the access hole provided. The gas connection to the unit is made to the 1/2- in. (12.7 mm) FPT gas inlet on the gas valve.

Install a gas supply line that runs to the heating section. Refer to Table 2 and the NFGC for gas pipe sizing. Do not use cast- iron pipe. It is recommended that a black iron pipe is used. Check the local utility for recommendations concerning existing lines. Size gas supply piping for 0.5 IN. W.C. maximum pressure drop. Never use pipe smaller than the 1/2- in. (12.7 mm) FPT gas inlet on the unit gas valve.

For natural gas applications, the gas pressure at unit gas connection must not be less than 4.0 IN. W.C. or greater than 13 IN. W.C. while the unit is operating. For propane applications, the gas pressure must not be less than 11.0 IN. W.C. or greater than 13 IN. W.C. at the unit connection.

A 1/8- in. (3.2 mm) NPT plugged tapping, accessible for test gauge connection, must be installed immediately upstream of the gas supply connection to the gas valve.

When installing the gas supply line, observe local codes pertaining to gas pipe installations. Refer to the NFGC NFPA 54/ANSI Z223.1 latest edition (in Canada, CAN/CGA B149.1).

NOTE: In the state of Massachusetts:

1. Gas supply connections MUST be performed by a licensed plumber or gas fitter.

2. When flexible connectors are used, the maximum length shall not exceed 36 in. (915 mm).

3. When lever handle type manual equipment shutoff valves are used, they shall be T- handle valves.

4. The use of copper tubing for gas piping is NOT approved by the state of Massachusetts.

In the absence of local building codes, adhere to the following pertinent recommendations:

1. Avoid low spots in long runs of pipe. Grade all pipe 1/4 in. (6.35 mm) for every 15 ft (4.6 m) of length to prevent traps. Grade all horizontal runs downward to risers. Use risers to connect to heating section and to meter.

2. Protect all segments of piping system against physical and thermal damage. Support all piping with appropriate straps, hangers, etc. Use a minimum of one hanger every 6 ft (1.8 m). For pipe sizes larger than 1/2 in., (12.7 mm) follow recommendations of national codes.

3. Apply joint compound (pipe dope) sparingly and only to male threads of joint when making pipe connections. Use only pipe dope that is resistant to action of liquedfied petroleum gases as specified by local and/or national codes. Never use Teflon tape.

4. Install sediment trap in riser leading to heating section (See Fig. 7). This drip leg functions as a trap for dirt and condensate.

5. Install an accessible, external, manual main shutoff valve in gas supply pipe within 6 ft (1.8 m) of heating section.

6. Install ground- joint union close to heating section between unit manual shutoff and external manual main shut- off valve.

7. Pressure test all gas piping in accordance with local and national plumbing and gas codes before connecting piping to unit.

NOTE: Pressure test the gas supply system after the gas supply piping is connected to the gas valve. The supply piping must be disconnected from the gas valve during the testing of the piping systems when test pressure is in excess of 0.5 psig. Pressure test the gas supply piping system at pressures equal to or less than 0.5 psig. The unit heating section must be isolated from the gas piping system by closing the external main manual shutoff valve and slightly opening the ground- joint union.

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in personal injury, death and/or property damage.

- Connect gas pipe to unit using a backup wrench to avoid damaging gas controls.

-Never purge a gas line into a combustion chamber. Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections. A fire or explosion may result causing property damage, personal injury or loss of life.

-Use proper length of pipe to avoid stress on gas control manifold.

- If a flexible connector is required or allowed by authority having jurisdiction, black iron pipe shall be installed at furnace gas valve and extend a minimum of 2 in. (51 mm) outside furnace casing.

- If codes allow a flexible connector, always use a new connector. Do not use a connector which has previously serviced another gas appliance.

! WARNING

Adhere to the following criteria when selecting, sizing, and installing the duct system:

1. Units are shipped for horizontal duct installation (by removing duct covers).

2. Select and size ductwork, supply- air registers, and return- air grilles according to American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) recommendations.

3. Use flexible transition between rigid ductwork and unit to prevent transmission of vibration. The transition may be screwed or bolted to duct flanges. Use suitable gaskets to ensure weather tight and airtight seal.

4. All units must have field- supplied filters or accessory filter rack installed in the return- air side of the unit. Recommended sizes for filters are shown in Table 1.

5. Size all ductwork for maximum required airflow (either heating or cooling) for unit being installed. Avoid abrupt duct size increases or decreases or performance may be affected.

6. Adequately insulate and weatherproof all ductwork located outdoors. Insulate ducts passing through unconditioned space, and use vapor barrier in accordance with latest issue of Sheet Metal and Air Conditioning Contractors National Association (SMACNA) and Air Conditioning Contractors of America (ACCA) minimum installation standards for heating and air conditioning systems. Secure all ducts to building structure.

7. Flash, weatherproof, and vibration- isolate all openings in building structure in accordance with local codes and good building practices.

Step 10 Install Electrical Connections

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

The unit cabinet must have an uninterrupted, unbroken electrical ground. This ground may consist of an electrical wire connected to the unit ground screw in the control compartment, or conduit approved for electrical groundwhen installed in accordance with NEC, NFPA 70 National Fire Protection Association (latest edition) (in Canada, Canadian Electrical Code CSA C22.1) and local electrical codes.

! WARNING

UNIT COMPONENT DAMAGE HAZARD

Failure to follow this caution may result in damage to the unit being installed.

1. Make all electrical connections in accordance with NEC NFPA 70 (latest edition) and local electrical codes governing such wiring. In Canada, all electrical connections must be in accordance with CSA standard C22.1 Canadian Electrical Code Part 1 and applicable local codes. Refer to unit wiring diagram.

2. Use only copper conductor for connections between field- supplied electrical disconnect switch and unit. DO NOT USE ALUMINUM WIRE.

3. Be sure that high- voltage power to unit is within operating voltage range indicated on unit rating plate. On 3- phase units, ensure phases are balanced within 2 percent. Consult local power company for correction of improper voltage and/or phase imbalance.

4. Insulate low- voltage wires for highest voltage contained within conduit when low- voltage control wires are in same conduit as high- voltage wires.

5. Do not damage internal components when drilling through any panel to mount electrical hardware, conduit, etc.

! CAUTION

High-Voltage Connections When routing power leads into unit, use only copper wire between disconnect and unit. The high voltage leads should be in a conduit until they enter the duct panel; conduit termination at the duct panel must be watertight.

The unit must have a separate electrical service with a field- supplied, waterproof disconnect switch mounted at, or within sight from, the unit. Refer to the unit rating plate, NEC and local codes for maximum fuse/circuit breaker size and minimum circuit amps (ampacity) for wire sizing.

The field- supplied disconnect switch box may be mounted on the unit over the high- voltage inlet hole when the standard power and low- voltage entry points are used (See Fig. 2 and 3 for acceptable location).

NOTE: Field supplied disconnect switch box should be positioned so that it does not cover up any of the unit gas combustion supply air louvers.

See unit wiring label (Fig. 14) and Fig. 9 for reference when making high voltage connections. Proceed as follows to complete the high- voltage connections to the unit.

Special Procedures for 208-V Operation

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Makesure thepower supply to theunit is switchedOFFbefore making any wiring changes. Tag the disconnect switch with a suitable warning label. With disconnect switch open, move blackwire from transformer (3/16 in.) terminalmarked 230 to terminal marked 200. This retaps transformer to primary voltage of 208 vac.

! WARNING

ELECTRICAL SHOCK AND EXPLOSION HAZARD

Failure to follow this warning could result in personal injury or death.

Beforemaking anywiring changes, make sure the gas supply is switched off first. Then switch off the power supply to the unit and install lockout tag.

! WARNING

Control Voltage Connections Do not use any type of power- stealing thermostat. Unit control problems may result.

Use no. 18 American Wire Gage (AWG) color- coded, insulated (35_C minimum) wires to make the control voltage connections between the thermostat and the unit. If the thermostat is located

48 EZ -- A

13

more than 100 ft (30.5 m) from the unit (as measured along the control voltage wires), use no. 16 AWG color- coded, insulated (35_C minimum) wires.

Locate the eight low voltage thermostat leads in 24 volt splice box. See Fig. 9 for connection diagram. Run the low- voltage leads from the thermostat, through the control wiring inlet hole grommet (Fig. 2 and 3), and into the low- voltage splice box. Provide a drip loop before running wires through panel. Secure and strain relief all wires so that they do not interfere with operation of unit. A gray wire is standard on 3- phase unit for connection to an economizer. Balance Point Setting-Thermidistat or Hybrid Thermostat BALANCE POINT TEMPERATURE-The balance point temperature is a setting which affects the operation of the heating mode. This is a field- selected input temperature (range 5 to 55_F) (- 15 to 12_C) where the Thermidistat or dual fuel thermostat will monitor outdoor air temperature and decide whether to enable or disable the heat pump. If the outdoor temperature is above the balance point, the heat pump will energize first to try to satisfy the indoor temperature demand. If the heat pump does not make a sufficient improvement within a reasonable time period (i.e. 15 minutes), then the gas furnace will come on to satisfy the indoor temperature demand. If the outdoor temperature is below the balance point, the heat pump will not be allowed to operate (i.e. locked out), and the gas furnace will be used to satisfy the indoor temperature. There are three separate concepts which are related to selecting the final balance point temperature. Read each of the following carefully to determine the best balance point in a hybrid installation:

1. Capacity Balance Temperature: This is a point where the heat pump cannot provide sufficient capacity to keep up with the indoor temperature demand because of declining outdoor temperature. At or below this point, the furnace is needed to maintain proper indoor temperature.

2. Economic Balance Temperature: Above this point, the heat pump is the most cost efficient to operate, and below this point the furnace is the most cost efficient to operate. This can be somewhat complicated to determine and it involves knowing the cost of gas and electricity, as well as the efficiency of the furnace and heat pump. For the most economical operation, the heat pump should operate above this temperature (assuming it has sufficient capacity) and the furnace should operate below this temperature.

3. Comfort Balance Temperature: When the heat pump is operating below this point, the indoor supply air feels uncomfortable (i.e. too cool). This is purely subjective and will depend on the homeowners idea of comfort. Below this temperature the gas furnace should operate in order to satisfy the desire for indoor comfort.

Transformer Protection The transformer is of the energy- limiting type. It is set to withstand a 30- sec. overload or shorted secondary condition. If an overload or short is present, correct overload condition and check for blown fuse on gas control board or Interface Fan Board. Replace fuse as required with correct size and rating.

PRE-START-UP

FIRE,EXPLOSION,ELECTRICALSHOCKHAZARD

Failure to follow this warning could result in personal injury, death or property damage. 1. Follow recognized safety practices and wear protective goggles when checking or servicing refrigerant system.

2. Do not operate compressor or provide any electric power to unit unless compressor terminal cover is in place and secured.

3. Do not remove compressor terminal cover until all electrical sources are disconnected and tagged.

4. Relieve and recover all refrigerant from system before touching or disturbing anything inside terminal box if refrigerant leak is suspected around compressor terminals.

5. Never attempt to repair soldered connection while refrigerant system is under pressure.

6. Do not use torch to remove any component. System contains oil and refrigerant under pressure. To remove a component, wear protective goggles and proceed as follows:

a. Shut off electrical power to unit and install lockout tag.

b. Relieve and reclaim all refrigerant from system using both high- and low- pressure ports.

Use a commercially available soap solution made specifically for the detection of leaks to check all connections. A fire or explosion may result causing property damage, personal injury or loss of life.

! WARNING

4. Verify the following conditions:

a. Make sure gas line is free of air. Before lighting the unit for the first time, perform the following with the gas valve in the OFF position:

NOTE: If the gas supply pipe was not purged before connecting the unit, it will be full of air. It is recommended that the ground joint union be loosened, and the supply line be allowed to purge until the odor of gas is detected. Never purge gas lines into a combustion chamber. Immediately upon detection of gas odor, retighten the union. Allow 5 minutes to elapse, then light unit.

b. Make sure that condenser- fan blade is correctly positioned in fan orifice. Leading edge of condenser- fan blade should be 1/2 in. (12 mm) maximum from fan orifice.

c. Make sure that air filter(s) is in place.

d. Make sure that condensate drain trap is filled with water to ensure proper drainage.

e. Make sure that all tools and miscellaneous loose parts have been removed.

START-UP Step 1 Check for Refrigerant Leaks

EXPLOSION HAZARD

Failure to follow this warning could result in death, serious personal injury, and/or property damage.

Never use air or gases containing oxygen for leak testing or operating refrigerant compressors. Pressurized mixtures of air or gases containing oxygen can lead to an explosion.

! WARNING

Proceed as follows to locate and repair a refrigerant leak and to charge the unit:

1. Locate leak and make sure that refrigerant system pressure has been relieved and reclaimed from both high- and low- pressure ports.

2. Repair leak following Refrigerant Service procedures.

NOTE: Install a bi- flow filter drier whenever the system has been opened for repair.

3. Add a small charge of R- 410A refrigerant vapor to system and leak- test unit.

4. Recover refrigerant from refrigerant system and evacuate to 500 microns if no additional leaks are not found.

5. Charge unit with Puron (R- 410A) refrigerant, using an electronic scale. Refer to unit rating plate for required charge.

Step 2 Unit Sequence of Operation Sequence of Operation

a. CONTINUOUS FAN

(1.) Thermostat closes circuit R to G energizing the blower motor for continuous fan.

b. COOLING MODE

(1.) If indoor temperature is above temperature set point thermostat closes circuits R to G, R to Y and R to O-The unit delivers cooling airflow.

c. HEAT PUMP HEATING MODE Outdoor temperature above balance point setpoint of thermostat.

(1.) On a call for heating, terminals Y and G of the Hybrid thermostat are energized. The Y signal is sent to the Defrost Board (DB) terminal Y. The DB has a built in five minute anti- short cycle timer which will not allow the compressor to restart before the time delay has expired.

(2.) T2 energizes the compressor contactor via the High Pressure Switch (HPS) and Low Pressure Switch (LPS). The compressor and outdoor fan start. Thermostat G energizes the Interface Fan Board terminal G. The blower motor is energized through contacts of the IFB.

(3.) When the thermostat removes the Y and G calls, the compressor contactor and outdoor fan are de- energized. The evaporator motor is de- ener- gized after a 90 sec. delay.

d. GAS HEATING MODE Outdoor temperature below balance point setpoint of thermostat.

Heating Sequence of Operation (See Fig. 14 and unit wiring label.)

On a call for heating, terminal W of the thermostat is energized, starting the induced- draft motor. When the pressure switch senses that the induced- draft motor is moving sufficient combustion air, the burner sequence begins. This function is performed by the integrated gas unit controller (IGC). The indoor (evaporator)- fan motor is energized 45 sec after flame is established. When the thermostat is satified and W is de- energized, the burners stop firing and the indoor (evaporator) fan motor shuts off after a 45- sec time- off delay. Please note that the IGC has the capability to automatically reduce the indoor fan motor on delay and increase the indoor fan motor off delay in the event of high duct static and/or partially- clogged filter.

NOTE: An LED (light- emitting diode) indicator is provided on the control board to monitor operation. The control board is located by removing the burner access panel (see Fig. 17). During normal operation, the LED is continuously on.

Step 3 Start- up Heating and Make Adjust- ments

UNIT COMPONENT DAMAGE HAZARD

Failure to follow this caution may result in damage to the unit being installed.

Complete the required procedures given in the Pre- Start-Up section before starting the unit. Do not jumper any safety devices when operating the unit.

! CAUTION

Complete the required procedures given in the Pre- Start-Up section before starting the unit. Do not jumper any safety devices when operating the unit. Make sure that burner orifices are

48 EZ -- A

15

properly aligned. Unstable operation my occur when the burner orifices in the manifold are misaligned.

Follow the lighting instructions on the heating section operation label (located on the inside of the control access panel) to start the heating section.

NOTE: Make sure that gas supply has been purged, and that all gas piping has been checked for leaks.

Check Heating Control Start and check the unit for proper heating control operation as follows (see furnace lighting instructions located on the inside of the control access panel):

1. Place room thermostat SYSTEM switch in the HEAT position and the fan switch is placed in AUTO position.

2. Set the heating temperature control of the thermostat above room temperature.

3. The induced- draft motor will start. 4. On a call for heating, the main burner should light within 5 sec. of the spark being energized. If the burners do not light, there is a 22- sec. delay before another 5- sec. try. If the burners still do not light, this sequence is repeated. If the burners do not light within 15 minutes from the initial call for heat, there is a lockout. To reset the control, break the 24- v power to W.

5. The evaporator fan will turn on 45 sec. after the flame has been established. The evaporator fan will turn off 45 sec. after the thermostat has been satisfied. Please note that the integrated gas unit controller (IGC) has the capability to automatically reduce the evaporator ON delay and in- crease the evaporator OFF delay in the event of high duct static and/or partially- clogged filter.

Check Gas Input Check gas input and manifold pressure after unit start- up (See Table 3). If adjustment is required proceed as follows: S The rated gas inputs shown in Table 3 are for altitudes from sea

level to 2000 ft (610 m) above sea level. These inputs are based

on natural gas with a heating value of 1025 Btu/ft3 at 0.60

specific gravity, or propane gas with a heating value of 2500

Btu/ft3 at 1.5 specific gravity.

IN THE U.S.A.:

The input rating for altitudes above 2,000 ft (610 m) must be reduced by 4% for each 1,000 ft (305 m) above sea level.

For installations below 2,000 ft (610 m), refer to the unit rating plate.

For installations above 2,000 ft (610 m) multiply the input by on the rating plate by the derate multiplier in Table 4 for correct input rate.

*In Canada see Canadian Altitude Adjustment. {Derate multiplier factors are based on midpoint altitude for altitude range.

IN CANADA:

The input rating for altitudes from 2,000 to 4,500 ft (610 m to 1372 m) above sea level must be derated 10% by an authorized Gas Conversion Station or Dealer.

EXAMPLE:

90,000 Btu/hr Input Furnace Installed at 4300 ft (1311 m).

Furnace Input Rate at Sea Level

X Derate Multiplier Factor

= Furnace Input Rate at Installation Altitude

90,000 X 0.90 = 81,000

When the gas supply being used has a different heating value or specific gravity, refer to national and local codes, or contact your distributor to determine the required orifice size.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in reduced unit and/or component life.

Do Not redrill an orifice. Improper drilling (burrs, out- of- round holes, etc.) can cause excessive burner noise and misdirection of burner flame. If orifice hole appears damaged or it is suspected to have been redrilled, check orifice hole with a numbered drill bit of correct size.

! CAUTION

Adjust Gas Input The gas input to the unit is determined by measuring the gas flow at the meter or by measuring the manifold pressure. Measuring the gas flow at the meter is recommended for natural gas units. The manifold pressure must be measured to determine the input of propane gas units.

Measure Gas Flow (Natural Gas Units)

Minor adjustment to the gas flow can be made by changing the manifold pressure. The manifold pressure must be maintained between 3.2 and 3.8 IN. W.C.

If larger adjustments are required, change main burner orifices following the recommendations of national and local codes.

NOTE: All other appliances that use the same meter must be turned off when gas flow is measured at the meter.

Proceed as follows:

1. Turn off gas supply to unit.

2. Remove pipe plug on manifold (See Fig. 11) and connect manometer. Turn on gas supply to unit.

3. Record number of seconds for gas meter test dial to make one revolution.

4. Divide number of seconds in Step 3 into 3600 (number of seconds in one hr).

5. Multiply result of Step 4 by the number of cubic feet (cu ft) shown for one revolution of test dial to obtain cubic feet (cu ft) of gas flow per hour.

6. Multiply result of Step 5 by Btu heating value of gas to obtain total measured input in Btuh. Compare this value with heating input shown in Table 3 (Consult the local gas supplier if the heating value of gas is not known).

EXAMPLE: Assume that the size of test dial is 1 cu ft, one revolution takes 32 sec, and the heating value of the gas is 1050 Btu/ft3. Proceed as follows:

1. 32 sec. to complete one revolution.

2. 3600 32 = 112.5.

3. 112.5 x 1 =112.5 ft3 of gas flow/hr.

4. 112.5 x 1050 = 118,125 Btuh input.

If the desired gas input is 115,000 Btuh, only a minor change in the manifold pressure is required.

FIRE AND UNIT DAMAGE HAZARD

Failure to follow this warning could result in personal injury or death and/or property damage.

Unsafe operation of the unit may result if manifold pressure is outside this range.

! WARNING

3. Replace regulator cover screw on gas valve (See Fig. 12).

4. Turn off gas supply to unit. Remove manometer from pressure tap and replace pipe plug on gas valve. (See Fig. 11.) Turn on gas to unit and check for leaks.

Measure Manifold Pressure (Propane Units)

Refer to propane kit installation instructions for properly checking gas input. NOTE: For installations below 2,000 ft (610 m), refer to the unit rating plate for proper propane conversion kit. For installations above 2,000 ft (610 m), contact your distributor for proper propane conversion kit.

Check Burner Flame With control access panel (see Fig. 17) removed, observe the unit heating operation. Watch the burner flames to see if they are light blue and soft in appearance, and that the flames are approximately the same for each burner. Propane will have blue flame (See Fig. 10). Refer to the Maintenance section for information on burner removal.

Normal Operation An LED (light- emitting diode) indicator is provided on the integrated gas unit controller (IGC) to monitor operation. The IGC is located by removing the control access panel (see Fig. 17). During normal operation, the LED is continuously on (See Table 5 for error codes).

Airflow and Temperature Rise The heating section for each size unit is designed and approved for heating operation within the temperature- rise range stamped on the unit rating plate.

Table 7 shows the approved temperature rise range for each heating input, and the air delivery cfm at various temperature rises for a given external static pressure. The heating operation airflow must produce a temperature rise that falls within the approved range.

Refer to Indoor Airflow and Airflow Adjustments section to adjust heating airflow when required.

Limit Switches Normally closed limit switch (LS) completes the control circuit. Should the leaving- air temperature rise above the maximum allowable temperature, the limit switch opens and the control circuit breaks. Any interruption in the control circuit instantly closes the gas valve and stops gas flow to the burners. The blower motor continues to run until LS resets.

When the air temperature at the limit switch drops to the low- temperature setting of the limit switch, the switch closes and completes the control circuit. The direct- spark ignition system cycles and the unit returns to normal heating operation.

Rollout Switch The function of the rollout switch is to close the main gas valve in the event of flame rollout. The switch is located above the main burners. When the temperature at the rollout switch reaches the maximum allowable temperature, the control circuit trips, closing the gas valve and stopping gas flow to the burners. The indoor (evaporator) fan motor (IFM) and induced draft motor continue to run until switch is reset. The IGC LED will display FAULT CODE 7.

Step 4 Start- up Cooling and Make Adjust- ments Complete the required procedures given in the Pre- Start-Up section before starting the unit. Do not jumper any safety devices when operating the unit. Do not operate the compressor when the outdoor temperature is below 40F (4.4C) (unless accessory low- ambient kit is installed). Do not rapid- cycle the compressor. Allow 5 minutes between on cycles to prevent compressor damage.

Checking Cooling Control Operation Start and check the unit for proper cooling control operation as follows:

1. Place room thermostat SYSTEM switch in OFF position. Observe that blower motor starts when FAN switch is placed in ON position and shuts down when FAN switch is placed in AUTO position.

2. Place SYSTEM switch in COOL position and FAN switch in AUTO position. Set cooling control below room temperature. Observe that compressor, condenser fan, and evaporator blower motors start. Observe that cooling cycle shuts down when control setting is satisfied. The evaporator fan will continue to run for 90 sec.

IMPORTANT: Three- phase, scroll compressors units are direction oriented. Unit must be checked to ensure proper compressor 3- phase power lead orientation. If not corrected within 5 minutes, the internal protector will shut off the compressor. The 3- phase power leads to the unit must be reversed to correct rotation. When turning backwards, the difference between compressor suction and discharge pressures will be near zero.

Checking and Adjusting Refrigerant Charge The refrigerant system is fully charged with PuronR (R- 410A) refrigerant and is tested and factory sealed. Allow system to operate a minimum of 15 minutes before checking or adjusting charge.

EXPLOSION HAZARD

Failure to follow this warning could result in death, serious personal injury, and/or property damage.

Never use air or gases containing oxygen for leak testing or operating refrigerant compressors. Pressurized mixtures of air or gases containing oxygen can lead to an explosion.

! WARNING

NOTE: Adjustment of the refrigerant charge is not required unless the unit is suspected of not having the proper PuronR (R- 410A) charge.

The charging label and the tables shown refer to system temperatures and pressures in cooling mode only. A refrigerant charging label is attached to the inside of the compressor access panel (see Fig. 17). The chart includes the required liquid line temperature at given discharge line pressures and outdoor ambient temperatures.

An accurate thermocouple- or thermistor- type thermometer, and a gauge manifold are required when using the subcooling charging method for evaluating the unit charge. Do not use mercury or small dial- type thermometers because they are not adequate for this type of measurement.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit damage.

When evaluating the refrigerant charge, an indicated adjustment to the specified factory charge must always be very minimal. If a substantial adjustment is indicated, an abnormal condition exists somewhere in the cooling system, such as insufficient airflow across either coil or both coils.

! CAUTION

Proceed as follows:

1. Remove caps from low- and high- pressure service fittings.

2. Using hoses with valve core depressors, attach low- and high- pressure gauge hoses to low- and high- pressure service fittings, respectively.

3. Start unit in Cooling Mode and let unit run until system pressures stabilize.

4. Measure and record the following:

a. Outdoor ambient- air temperature (F [C] db).

b. Liquid line temperature (F [C]). c. Discharge (high- side) pressure (psig).

d. Suction (low- side) pressure (psig) (for reference only).

5. Using Cooling Charging Charts, compare outdoor- air temperature(F [C] db) with the discharge line pressure (psig) to determine desired system operating liquid line temperature (See Fig. 15).

6. Compare actual liquid line temperature with desired liquid line temperature. Using a tolerance of 2F (1.1C), add refrigerant if actual temperature is more than 2F (1.1C) higher than proper liquid line temperature, or remove refrigerant if actual temperature is more than 2F (1.1C) lower than required liquid line temperature.

NOTE: If the problem causing the inaccurate readings is a refrigerant leak, refer to the Check for Refrigerant Leaks section.

Indoor Airflow and Airflow Adjustments

UNIT OPERATION HAZARD

Failure to follow this caution may result in unit damage.

For cooling operation, the recommended airflow is 350 to 450 cfm for each 12,000 Btuh of rated cooling capacity. For heating operation, the airflow must produce a temperature rise that falls within the range stamped on the unit rating plate.

CAUTION!

NOTE: Be sure that all supply- and return- air grilles are open, free from obstructions, and adjusted properly.

ELECTRICAL SHOCK AND EXPLOSION HAZARD

Failure to follow this warning could result in personal injury or death.

Before making any indoor wiring adjustments, shut off gas supply. Then disconnect electrical power to the unit and install lockout tag before changing blower speed.

! WARNING

This unit has independent fan speeds for gas heating and cooling. In addition, this unit has the field-selectable capability to run two different cooling fan speeds: A normal cooling fan speed (350~400 CFM/Ton) and an enhanced dehumidification fan speed (As low as 320 CFM/Ton) for use with either a dehumidistat or a thermostat that supports dehumidification.

This unit is factory-set up for use with a single cooling fan speed. The cooling speed is marked LOW on the interface fan board (IFB) (See Fig. 13) . The factory-shipped settings are noted in Table 7. There are 3 additional speed tap wires available for use in either gas heating or cooling (For color coding on the indoor fan motor leads, see Table 6). The additional 3 speed tap wires are shipped loose with vinyl caps and are located in the control box, near the interface fan board (IFB) (See Fig. 13).

Gas Heating Fan Speed Set-up To change the gas heating speed:

1. Remove the vinyl cap off of the desired speed tap wire (Refer to Table 6 for color coding). Table 7 shows the temperature rise associated with each fan speed for a given static pressure. Make sure that the speed chosen delivers a temperature rise within the rise range listed on the unit rating plate.

2. Remove the current speed tap wire from the GAS HEAT terminal on the interface fan board (IFB) (Fig. 13) and place vinyl cap over the connector on the wire.

3. Connect the desired speed tap wire to the GAS HEAT terminal on the interface fan board (IFB).

Single Cooling Fan Speed Set-up (Dehumidification feature not used) To change cooling speed:

1. Remove the vinyl cap off of the desired speed tap wire (Refer to Table 6 for color coding). Add the wet coil pressure drop in Table 9 to the system static to determine the correct cooling airflow speed in Table 7 that will deliver the nominal cooling airflow as listed in Table 1 for each size.

2. Remove the current speed tap wire from the LOW terminal on the interface fan board (IFB) (See Fig. 13) and place vinyl cap over the connector on the wire.

3. Connect the desired speed tap wire to the LOW terminal on the interface fan board (IFB).

Two Cooling Fan Speeds Set-up (Dehumidification feature used) IMPORTANT: Dehumidification control must open control circuit on humidity rise above set point.

Use of the dehumidification cooling fan speed requires use of either a 24 VAC dehumidistat or a thermostat which includes control of a 24 VAC dehumidistat connection. In either case, the dehumidification control must open the control circuit on humidity rise above the dehumidification set point.

1. Remove fan speed tap wire from the LOW terminal on the interface fan board (IFB) (See Fig. 13).

2. Determine correct normal cooling fan speed for unit and application. Add the wet coil pressure drop in Table 9 to the system static to determine the correct cooling airflow speed in Table 7 that will deliver the nominal cooling airflow as listed in Table 1 for each size.

3. Remove the vinyl cap off of the desired speed tap wire (Refer to Table 6 for color coding) for the normal cooling fan speed and place desired speed tap wire on HIGH on the interface board.

4. Refer to airflow tables (Table 7) to determine allowable speeds for the dehumidification cooling fan speed. In Table 7, speeds that are not allowed for dehumidification cooling are shaded.

5. Remove the vinyl cap off of the desired speed tap wire (Refer to Table 6 for color coding) for the dehumidification cooling fan speed and place desired speed tap wire on the LOW connection on the interface board (IFB). Verify that static pressure is in the acceptable range for the speed tap to be used for dehumidification cooling.

6. Use any spare vinyl plugs to cap any unused speed tap wires.

Continuous Fan Operation When the DEHUM feature is not used, the continuous fan speed will be the same as cooling fan speed. When the DEHUM feature is used, the continuous fan will operate on IFB LOW speed when the DH control lead is not energized, or IFB HIGH speed when the DH lead is energized (see Fig. 13).

NOTE: For heat pump operation, the recommended airflow is 350 to 450 CFM for each 12,000 Btuh of rated cooling capacity.

EXPLOSION, PERSONAL INJURY AND ENVIRONMENTAL HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

System under pressure. Relieve pressure and recover all refrigerant before system repair or final unit disposal. Use all service ports and open all flow- control devices, including solenoid valves.

! WARNING

If oil is detected or if low cooling performance is suspected, leak- test all refrigerant tubing using an electronic leak- detector, halide torch, or liquid- soap solution. If a refrigerant leak is detected, refer to the Check for Refrigerant Leaks section.

If no refrigerant leaks are found and low cooling performance is suspected, refer to the Checking and Adjusting Refrigerant Charge section.

Gas Input The gas input does not require checking unless improper heating performance is suspected. If a problem exists, refer to the Start-Up section.

Indoor Airflow The heating and/or cooling airflow does not require checking unless improper performance is suspected. If a problem exists, be sure that all supply- and return- air grilles are open and free from obstructions, and that the air filter is clean. When necessary, refer to

the Indoor Airflow and Airflow Adjustments section to check the system airflow.

Check Defrost Thermostat The defrost thermostat is usually located on the lowest liquid leaving circuit of the left condenser coil (see Fig. 20). The thermostat closes at 32_F (0_C) and opens at 65_F (18_C).

Puron Items Metering Device (Thermostatic Expansion Valve & Piston) This unit uses both a hard shutoff, balance port TXV in the indoor coil and a piston in each side of the outdoor coil. The TXV maintains a constant superheat at the evaporator coil exit (cooling mode) resulting in higher overall system efficiency.

Pressure Switches Pressure switches are protective devices wired into control circuit (low voltage). They shut off compressor if abnormally high or low pressures are present in the refrigeration circuit. These pressure switches are specifically designed to operate with Puron (R- 410A) systems. R- 22 pressure switches must not be used as replacements for the Puron (R- 410A) system.

Loss of Charge Switch This switch is located on the liquid line and protects against low suction pressures caused by such events as loss of charge, low airflow across indoor coil, dirty filters, etc. It opens on a pressure drop at about 20 psig. If system pressure is above this, switch should be closed. To check switch:

1. Turn off all power to unit.

45

C99097

Fig. 23 - Refrigerant Circuit

2. Disconnect leads on switch.

3. Apply ohm meter leads across switch. You should have continuity on a good switch.

NOTE: Because these switches are attached to refrigeration system under pressure, it is not advisable to remove this device for troubleshooting unless you are reasonably certain that a problem exists. If switch must be removed, remove and recover all system charge so that pressure gauges read 0 psi. Never open system without breaking vacuum with dry nitrogen.

High-Pressure Switch

The high- pressure switch is located in the discharge line and protects against excessive condenser coil pressure. It opens at 650 psig.

High pressure may be caused by a dirty outdoor coil, failed fan motor, or outdoor air recirculation. To check switch:

1. Turn off all power to unit.

2. Disconnect leads on switch.

3. Apply ohm meter leads across switch. You should have continuity on a good switch.

Copeland Scroll Compressor (Puron Refrigerant)

The compressor used in this product is specifically designed to operate with Puron (R- 410A) refrigerant and cannot be interchanged.

The compressor is an electrical (as well as mechanical) device. Exercise extreme caution when working near compressors. Power should be shut off, if possible, for most troubleshooting techniques. Refrigerants present additional safety hazards.

EXPLOSION HAZARD

Failure to follow this warning could result in personal injury or death and/or property damage.

Wear safety glasses and gloves when handling refrigerants. Keep torches and other ignition sources away from refrigerants and oils.

! WARNING

The scroll compressor pumps refrigerant throughout the system by the interaction of a stationary and an orbiting scroll. The scroll compressor has no dynamic suction or discharge valves, and it is more tolerant of stresses caused by debris, liquid slugging, and flooded starts. The compressor is equipped with an internal pressure relief port. The pressure relief port is a safety device, designed to protect against extreme high pressure. The relief port has an operating range between 550 and 625 psig differential pressure.

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this warning could result in personal injury or equipment damage.

This system uses Puron (R- 410A) refrigerant which has higher operating pressures than R- 22 and other refrigerants. No other refrigerant may be used in this system. Gauge set, hoses, and recovery systemmustbe designed to handlePuron. If you are unsure, consult the equipment manufacturer.

WARNING! Refrigerant System

This information covers the refrigerant system of the 48EZ-A, including the compressor oil needed, servicing systems on roofs containing synthetic materials, the filter drier and refrigerant charging.

Compressor Oil If additional oil is needed use Uniqema RL32- 3MAF. If this oil is not available, use Copeland Ultra 32CC or Mobil Artic EAL22CC. This oil is extremely hygroscopic, meaning it absorbs water readily. POE oils can absorb 15 times as much water as other oils designed for HCFC and CFC refrigerants. Take all necessary precautions to avoid exposure of the oil to the atmosphere.

47

Servicing Systems on Roofs and with Synthetic materials

POE (polyolester) compressor lubricants are known to cause long term damage to some synthetic roofing materials.

Exposure, even if immediately cleaned up, may cause embrittlement (leading to cracking) to occur in one year or more. When performing any service that may risk exposure of compressor oil to the roof, take appropriate precautions to protect roofing. Procedures which risk oil leakage include, but are not limited to, compressor replacement, repairing refrigerant leaks, replacing refrigerant components such as filter drier, pressure switch, metering device, coil, accumulator, or reversing valve.

Synthetic Roof Precautionary Procedure

1. Cover extended roof working area with an impermeable polyethylene (plastic) drip cloth or tarp. Cover an approximate 10x10 ft (3x3 m) area.

2. Cover area in front of the unit service panel with a terry cloth shop towel to absorb lubricant spills and prevent run- offs, and protect drop cloth from tears caused by tools or components.

3. Place terry cloth shop towel inside unit immediately under component(s) to be serviced and prevent lubricant run- offs through the louvered openings in the unit base.

4. Perform required service.

5. Remove and dispose of any oil contaminated material per local codes.

Liquid Line Filter Drier

This filter drier is specifically designed to operate with Puron. Use only factory- authorized components. Filter drier must be replaced whenever the refrigerant system is opened. When removing a filter drier, use a tubing cutter to cut the drier from the system. Do not unsweat a filter drier from the system. Heat from unsweating will release moisture and contaminants from drier into system.

Puron (R- 410A) Refrigerant Charging

Refer to unit information plate and charging chart. Some R- 410A refrigerant cylinders contain a dip tube to allow liquid refrigerant to flow from cylinder in upright position. For cylinders equipped with a dip tube, charge Puron units with cylinder in upright position and a commercial metering device in manifold hose. Charge refrigerant into suction- line.

TROUBLESHOOTING Use the Troubleshooting Guides (See Tables 12- 14) if problems occur with these units.

START-UP CHECKLIST Use Start-Up checklist to ensure proper start- up procedures are followed.

PURONR (R- 410A) QUICK REFERENCE GUIDE

S Puron refrigerant operates at 50- 70 percent higher pressures than R- 22. Be sure that servicing equipment and replacement

components are designed to operate with Puron

S Puron refrigerant cylinders are rose colored.

S Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400 or DOT BW400.

S Puron systems should be charged with liquid refrigerant. Use a commercial type metering device in the manifold hose when

charging into suction line with compressor operating

S Manifold sets should be minimum 700 psig high side and 180 psig low side with 550 psig low- side retard.

S Use hoses with minimum 700 psig service pressure rating.

S Leak detectors should be designed to detect HFC refrigerant.

S Puron, as with other HFCs, is only compatible with POE oils.

S Vacuum pumps will not remove moisture from oil.

S Do not use liquid- line filter driers with rated working pressures less than 600 psig.

S Do not leave Puron suction line filter driers in line longer than 72 hrs.

S Do not install a suction- line filter drier in liquid line.

S POE oils absorb moisture rapidly. Do not expose oil to atmosphere.

S POE oils may cause damage to certain plastics and roofing materials.

S Wrap all filter driers and service valves with wet cloth when brazing.

S A factory approved liquid- line filter drier is required on every unit.

S Do NOT use an R- 22 TXV.

S Never open system to atmosphere while it is under a vacuum.

S When system must be opened for service, recover refrigerant, evacuate then break vacuum with dry nitrogen and replace filter

driers. Evacuate to 500 microns prior to recharging.

S Do not vent Puron into the atmosphere.

S Observe all warnings, cautions, and bold text.

S All indoor coils must be installed with a hard shutoff Puron TXV metering device.
