PERSONAL INJURY, DEATH AND / OR PROPERTY DAMAGE HAZARD

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

Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer, service agency, or your distributor or branch for information or assistance. The qualified installer or service agency must use factory- authorized kits or accessories when modifying this product.

Read and follow all instructions and warnings, including labels shipped with or attached to unit before operating your new heat pump.

! WARNING

ABOUT YOUR HEAT PUMP SYSTEM Identifying Your System Your new Carrier heat pump system is what we call a split system. It has an outdoor unit and an indoor unit connected to each other with copper tubing called refrigerant lines. Each of these units has a rating plate with the model and serial numbers you will need to reference when calling an authorized Carrier dealer about your system.

Take a few moments now to locate those numbers and record them in the spaces provided on the cover of this booklet.

USING YOUR NEW CARRIER SYSTEM Your Carrier heat pump system is controlled by a wall- mounted thermostat installed inside your home. Because there are so many thermostats available, please refer to the owners manual supplied with your thermostat for complete details on system operation.

INFINITY OPERATION If you own an Infinity two- stage heat pump system, you may notice your system runs for longer periods of time. Nearly 80% of the time its running, it is operating in low- stage, and your indoor temperature will remain more consistent with fewer drafts, better humidity control, enhanced comfort and enhanced energy efficiency.

HEATING AND COOLING YOUR HOME For heating or cooling operation, make sure the System or Mode control is set to the appropriate mode. Then, adjust the Temperature control to your desired setting. Finally, use the Fan control to select Automatic (turns on and off as heating is needed) or On (runs continuously). Depending on your typical heating needs, your home comfort system may also include a supplementary heating source that will automatically turn on as needed. You may also select this heat source manually if desired.

OPERATION UNDER EXTREME CONDITIONS Your heat pump will run as long as necessary to maintain the indoor temperature selected on your thermostat. On extremely hot days, your heat pump will run for longer periods at a time than on moderate days. Your system will also run for longer periods of time under the following conditions:

S Frequent opening of exterior doors S Operating laundry appliances S Taking hot showers S More than the usual number of people present in the home S More than the normal number of electric lights in use S Drapes or blinds are open on the sunny side of the home IMPORTANT HEAT PUMP FACTS Heat pump systems have a few unique features and operations that you should be aware of: S During the heating cycle, air from your registers may seem

cooler than you may expect. This is because your heat pump delivers a constant flow of air at around 90 to about 105 F, compared to sudden blasts of hot air provided by a typical furnace. This air may feel cool if it is slightly below your body temperature, however it is warm enough to keep your home comfortable.

S Ice or frost may form on the outdoor coil during winter heating operation. Your heat pump will automatically melt the ice using its defrost cycle. During defrost, you may see steam or fog rising from the outdoor unit, which is normal.

S Heat pumps installed in areas expecting snow are elevated with support feet.

ROUTINE MAINTENANCE Simple, routine maintenance as described below will enhance your heat pump systems ability to operate economically and dependably. Always remember the following safety precautions:

! WARNING ELECTRICAL SHOCK HAZARD

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

Disconnect all electrical power to the indoor air handler or furnace before removing access panels to perform any maintenance. Disconnect power to both the indoor and outdoor units.

NOTE: There may be more than one electrical disconnect switch.

PERSONAL INJURY AND/OR PRODUCT AND PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in personal injury or product and property damage.

Although special care has been taken to minimize sharp edges in the construction of your unit, be extremely careful when handling parts or reaching into the unit.

CAUTION!

S Keep Filter Clean A clogged or improperly installed air filter on your indoor unit will increase operating costs and shorten the life of the unit. For detailed filter cleaning information refer to indoor unit literature. S Do Not Block Floor, Wall or Ceiling Vents When drapes, furniture, toys or other common household items block vents, the restricted airflow lessens the systems efficiency and life span. S Do Not Cover or Block Outdoor Unit The outdoor unit needs unrestricted airflow. Do not cover it or place items on or next to it. Do not allow grass clippings, leaves, or other debris to accumulate on the sides or top of the unit. And, maintain a 12 (304.8 mm) minimum clearance between the outdoor unit and tall grass, vines, shrubs, etc. S Check Condensate Drain Your heat pump removes humidity from your home during the cooling season. After a few minutes of operation, water should trickle from the condensate drain of the indoor coil. Check this occasionally to be sure the drain system is not clogged. Drainage will be limited if you live in a very dry environment. S Do Not Operate Below 55F/12.78C in Cooling Mode Your outdoor unit is not designed to operate when outdoor temperatures are lower than 55_F/12.78_C without modification. If operation below this temperature is required, consult your Carrier dealer. S Do Not Operate Above 66F/18.89_C in Heating Mode Your outdoor unit is not designed to operate on heating mode when outdoor temperatures are higher than 66F/18.89_C. You can safely operate the system above 66F/18.89_C on emergency or auxiliary heat. S Base Pan Drainage Periodically check for and remove debris that has settled around the base of your outdoor unit. This will ensure proper drainage of the base pan and eliminate standing water inside the outdoor unit. S Level Installation Your Carrier dealer will install the outdoor unit in a level position. If the support base settles or shifts and the unit is no longer level,

be sure to re- level it promptly to assure proper drainage. If you notice water or ice collecting beneath the unit, arrange for it to be drained away from the unit.

SEA COAST COIL MAINTENANCE Coastal locations often require additional maintenance of the outdoor unit due to highly corrosive airborne ocean salt. Although your new Carrier system is made of galvanized metal and is protected by top- grade paint, take the additional precaution of periodically washing all exposed surfaces and the outdoor coil approximately every 3 months. Consult your installing Carrier dealer for proper cleaning intervals and procedures for your geographic area or ask about a service contract for regularly scheduled professional cleaning and inspections.

TROUBLESHOOTING Before you request dealer service, check for these easily solved problems: S Check the indoor and outdoor disconnect switches Also check

your main electrical panel circuit breakers or fuses. S Check for sufficient airflow. Air filter(s) should be reasonably

clean and interior vents should be open and unobstructed. S Check thermostat settings. For cooling, your desired

temperature setting should be LOWER than the displayed room temperature, and the System/Mode control should be on Cool or Auto. For heating, your temperature setting should be HIGHER than the displayed room temperature, and the System/Mode control is set to Heat or Auto.

S Time delays - depending on the Carrier heat pump you have, there may be delays in unit operation that are built-in to protect the equipment and your comfort. Don't be alarmed if you notice a time delay in operation. It may be a standard protection feature of your equipment. Check with your Carrier Dealer for more information on time delays.

If you need to contact your Carrier dealer for troubleshooting and/or repairs, be sure to have the model and serial numbers of your equipment available (there are spaces on the cover for you to write this information).

REGULAR DEALER MAINTENANCE In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a properly trained service technician. Many dealers offer this service at a reduced rate with a service contract. Some service contracts offer additional benefits such as parts discounts and no additional charge for after hours or emergency service. Your annual system inspection should include: S Routine inspection of air filter(s) with replacement or cleaning

as required S Inspection and cleaning of the blower wheel housing and

motor S Inspection and, if required, cleaning of indoor and outdoor

coils S Inspection of the indoor coil drain pan, as well as the primary

and secondary drain lines. If the system has an auxiliary drain pan and line, they should be inspected at this time as well. Service should include cleaning if required.

S Check all electrical wiring and connections S Check for secure physical connections of individual parts in

each unit S Operational check of the heat pump system to determine actual

working condition. Necessary repair and, or adjustment should be performed at this time.
