SAFETY CONSIDERATIONS

See Fig.1 for Proposition 65 warning label.

Fig. 1 Proposition 65 Warning Label

GENERAL The overhead induction beam distribution unit has been de- signed to give the customer many years of trouble-free ser- vice. Each unit contains a row or number of rows of aerody- namic airflow nozzles located within the 20-gage heavy duty housing assembly. These airflow nozzles deliver the proper ventilation air from the main outdoor ventilation unit and pro- duce an airflow profile across the coil. This aerodynamic air- flow causes a venturi effect across the coil face, which induc- es air from the room across the coil surface. When cool water or hot water is pumped through the coil, the induced airflow across the coil is heated or cooled, then mixed with the prima- ry airflow from the nozzles to deliver conditioned airflow to the space.

SAFETY NOTE Air-handling equipment will provide safe and reliable service when operated within design specifications. The equipment should be operated and serviced only by authorized personnel who have a thorough knowl- edge of system operation, safety devices and emer- gency procedures. Good judgment should be used in applying any manu- facturers instructions to avoid injury to personnel or damage to equipment and property.

This product can expose you to chemicals including styrene-butadiene rubber (SBR), which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov

Storage and Handling Inspect for damage upon receipt. Shipping damage claims should be filed with shipper at time of delivery. Store in a clean, dry, and covered location. Do not stack cartons. When unpacking units, care should be taken that the inlet collars and water connections do not become damaged.

The 36IBAC unit packaging includes a base tray and an in- verted box cover. Remove the box cover to fully expose the unit. The 36IBAN and 36IBAR units are packaged in cardboard cartons. Open the carton top and fold the flaps back to gain access to the unit. Two people are required to lift the unit out of the carton. These units are shipped with the grille attached, and when setting the unit down, care must be taken to put it on a clean, soft surface so as not to scratch the grille face. The 36IBAS, M, L, and J units are packaged in cardboard cartons. Open the carton top and cut the carton vertically on the side where the duct collar is located. The grille is attached to the unit and should not be removed. After cutting the side of the carton, remove the unit from the box and set it on a clean surface being careful not to scratch the grille.

Initial Inspection Once items have been removed from the carton, check care- fully for damage to duct connections, coils, or controls. File damage claim immediately with transportation agency and notify Carrier.

Installation Precaution Check that construction debris does not enter unit or ductwork. Accumulated dust and construction debris distributed through the ductwork can adversely affect unit operation.

Codes Install units in compliance with all applicable code requirements.

PRE-INSTALLATION

Prepare Jobsite for Unit Installation To save time and to reduce the possibility of costly errors, set up a complete sample installation in a typical room at jobsite. Check all critical dimensions such as pipe, wire, and duct connection requirements. Refer to job drawings and product dimension drawings as required (see Fig. 2-29). Instruct all trades in their part of the installation. Refer to Tables 1-6 and Fig. 2-29 for unit data.

CAUTION

Do not lift the unit by the drain pipes, water piping, or metal duct. To prevent damage, units should be lifted us- ing the mounting brackets.

IMPORTANT: Prior to hanging the unit, remove the two cotter pins holding the supply/return section to the grille frame. Failure to remove these pins will pre- vent access to coils and internal workings of the units.

INSTALLATION It is recommended that unit locations be separated by a mini- mum of 8 ft from grille edge to grille edge.

Step 1 Install Unit 36IBAC

There are two mounting brackets bolted to each side of the unit. These brackets will accept field-supplied 1/4-in. all- thread rod to facilitate the hanging of this unit. These brackets can also be used for wire hanging systems such as Sheet Met- al and Air Conditioning Contractors National Association (SMACNA) approved hanging systems. Set the unit on a ca- ble lift or other lifting device to lift it above the ceiling level. Be careful to ensure the lifting platform is wide enough to reach the outer shell of the unit. The center drain pan and coil should not be used to support the unit. To hang the unit, the factory recommends securing two strut channels, 24-in. apart, to the building structure where the unit is to be hung. Secure two 1/4-in. all-thread rods or wire about 20-in. apart on each channel so that they hang down to the top of where the unit is to be hung. Raise the unit and screw the all-thread rod or wire hanging from the building channels into the mounting brackets. The rod should be secured with a washer and lock nut. Final elevation and horizontal adjustments can be made to align the unit with the diffuser. The mounting brackets have holes for the rod approximately every inch. The unit can be adjusted to meet the ceiling grid using these bracket holes, and by raising and lowering the unit to align with the ceiling by adjusting the nuts on the all-thread rod or wire on the building channel.

36IBAN

There are two holes (1/4-in. for 36IBANA, 1/2-in. for 36IBANB) on each side of the unit to facilitate hanging with an S hook and cable or chain to the building support. The drain pan and coil should not be used to support the unit. These units should be hung in a manner to align with the planned ceiling grid. Final elevation and horizontal adjust- ments can be made to align the diffuser in the ceiling grid by raising and lowering the unit to the ceiling grid.

36IBAS,M,R,L,J

There is a hanging bracket with two 5/16-in. holes on each side of the unit to facilitate hanging with 1/4-in. all-thread rod or wire. The drain pan and coil should not be used to support the unit. To hang the unit, hang four 1/4-in. all-thread rod or wire from the building support, aligning the unit with the planned ceiling grid. Final elevation and horizontal adjustments can be made to align the diffuser in the ceiling grid by raising and lowering the unit to the ceiling grid.

Step 2 Connect Induction Beams to the Pip- ing System All piping connections can be made before the ceiling grid is in place. It is important to connect the supply water to the supply water connections and return water to the return water connections. These connections have been labeled on the unit pipe stub-outs. Be sure all air is vented at the coil before mak- ing final connections at the return. Pipes for chilled water systems must be covered with sealed insulation to prevent condensation. Both the supply and re- turn pipework should be insulated. Induction beams must be capable of being shut off and hav- ing flow controlled. A valve set providing these functions should be field-supplied and installed on every zone. In order to permit adjustment of the induction beam in verti- cal and lateral directions, it may be practical to connect it us- ing flexible pipes. Flexible pipes offer greater resistance to flow than fixed pipes; therefore, it may be suitable to select flexible pipes with larger dimensions than fixed pipes.

Step 3 Connect Induction Beams to the Con- densate Drainage System The 36IB units have one 3/4-in. condensate drain pan connec- tion. When not piping to a condensate drain, the unit should be supplied with a plug or a float switch (shipped separately). The float switch should be wired in series to a room control- ler to shut off the coil valve if sufficient condensate should build up. If multiple units are used in a single zone, the switches should be wired in series to the room controller. If the unit is piped to a condensate removal system, the unit may be supplied with a trap and connection fitting (shipped sepa- rately). A height extension collar option may be factory-pro- vided and installed to give additional height for gravity drain- age. A standard unit provides 33/4-in. of height without any extension collar for gravity drainage of condensate. For grav- ity drainage, a slope of 1/4-in. per foot of condensate pipe length is required.

Step 4 Connect Induction Beams to the Pri- mary Air Ducting System A short section of insulated flexible duct can be used to con- nect the primary air ductwork to the unit. Make sure that the

flexible duct connection to the unit is sealed airtight. A field- supplied balancing damper should be provided in this prima- ry air duct to facilitate the air supply balancing of each unit to the scheduled static pressure at the unit inlet.

ADJUSTMENT

Airflow Balancing Procedure To balance the air system for the induction beams, it is only necessary to adjust the inlet static pressure at each induction unit to the values shown on the schedule for each room. The inlet static pressure should be read at the duct connection to each induction beam. A static pressure tap is supplied on each induction unit for a balancer to take their readings at. The bal- ancing contractor should attach a magnehelic gage to the fac- tory-mounted pressure tap and adjust the volume damper to the proper inlet pressure. If multiple induction beams in a given space are not accessi- ble to measure the static pressure at the inlet to each unit, they can be balanced as a group, as follows. 1. Add up all the scheduled primary air to each induction

beam on a given primary air duct branch feeding a com- mon area.

2. Adjust the damper to that branch to allow the primary air quantity determined above to the space. Since induction beams all operate linearly at static pressures between 0.4 and 1.0-in. wg, all terminals on the primary air branch to a given space will operate at the common static pressure available in that branch duct that will produce the total primary air measured.

3. Total supply air is dependent on the primary air and static pressure at the unit. It cannot be directly measured.

MAINTENANCE Once per year, remove the center core of grille and vacuum the internal heating and cooling coil with a soft vacuum brush. The removable grille can also be vacuumed as re- quired. If the unit was provided with a lint screen filter in- stalled, remove the filter and vacuum off the lint. The diffuser is used to access the coil. No tools are required. On 36IBAC units, the diffuser is spring loaded to allow ac- cess by pushing from one side. Pull back on the face core and remove the face core out of its channel frame. The unit con- tains a quick spring latch arrangement that slides in and out of the diffuser frame. On 36IBAM,N,R,S,L,J units, the coil can be accessed by removing the fasteners located on the face of the grille. Supply and return face sections are separate and can be removed.

Condensate Float Switch Wiring The float switch is a normally closed dry contact electric circuit. When the float senses water, the circuit opens and the motorized water control valve is deactivated (closed). If the water control valve is a power open/spring return device, no relay is required to reset the valve. If the water control valve is a power open/ power cl
