When your heat pump needs additional heat to keep you comfort- able, your Bryant electronic thermostat will turn on the supple- mental heat (if equipped) and will display the ªAUX HTº message.
IV. DEFROST MODE
When your heat pump is providing heat to your home and the outdoor temperature drops below 45ÊF, moisture may begin to freeze on the surface of the coil. If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat absorbed from the outside air. So, to maintain
Do not be alarmed if steam or fog appears at the outdoor unit during defrost mode. Water vapor from the melting ice may condense into a mist in the cold outside air. During certain weather conditions such as heavy snow and freezing rain it is not uncommon for ice to build up on the unit grille. This is normal for these weather conditions. Do not attempt to remove the ice from the unit grille. This condition will not affect the proper function of the unit and will clear a few days.
PERFORMING ROUTINE MAINTENANCE
With the proper maintenance and care, your heat pump will operate economically and dependably. Maintenance can be accom- plished easily by referring to the following directions. However, before performing maintenance, consider these important safety precautions:
WARNING: Disconnect all electrical power to the in- door 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 1 electrical disconnect switch. Electrical shock can cause serious injury or death.
CAUTION: Although special care has been taken to minimize sharp edges in the construction of your unit, to avoid injury be extremely careful when handling parts or reaching into the unit.
I.CHECK THE AIR FILTER
A dirty air filter will cause excessive strain on the compressor and blower motor. This can cause the components to overheat and automatically shut down. In the worst case, the components will fail and need to be replaced. To avoid inefficient or failed operation of your unit, CHECK THE FILTER(S) EVERY 3 TO 4 WEEKS. Replace filter(s) when necessary, or clean the filter(s) if you have the reusable type.
Disposable filters should be replaced by similar, new filters of the same dimensions.
Reusable, permanent filters should be washed in a solution of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER MUST BE COMPLETELY DRY BEFORE BEING REINSTALLED. To avoid prolonged shutdown of your unit while a filter is drying, you should have an extra filter on hand. This allows you to rotate between the two with minimal downtime for your comfort system. Extra filters may be purchased from your dealer.
The filters(s) and filter rack for a packaged system are supplied and installed by the contractor or dealer. Typically, the filter(s) and rack are located in the

If your system includes a high efficiency or electronic air cleaner, refer to air cleaner User's Manual for proper filter cleaning or replacement.
II.OUTDOOR COIL
If grass clippings, leaves, shrubbery, and debris are kept away from the unit, minimal care should be sufficient to keep the system functioning properly. However, if the outdoor coil becomes dirty, use a vacuum cleaner or shop vac with soft brush attachment to clean the exterior surface. Vacuum coil surface using an up and down motion. Be careful not to bend or damage fins.
If dirt is deep in the coil, contact your dealer for service. Do not attempt this yourself.
III.OUTDOOR COILÐSEA COAST
If your unit is located near the ocean, special maintenance is required. Ocean mist/breeze carries salt, which is corrosive to most metals. Although your new unit is made out of galvanized metal and is protected by
IV. UNIT SUPPORT
Your packaged heat pump unit should be maintained at a level position. If its support should shift or settle so that the unit is no longer level, you should correct the condition. Relevel it promptly to assure water drains out of the unit. If you notice that water or ice collects beneath the unit, arrange for it to be drained away from the unit.
BEFORE YOUR REQUEST A "SERVICE CALL"
CHECK FOR THESE EASILY SOLVED PROBLEMS:
1.Check the indoor and outdoor disconnect switches. Verify that circuit breakers are ON or that fuses have not blown.
2.Check for sufficient airflow. Check the air filter(s) for any accumulations of dirt. Check for blocked
3.Check the settings on your indoor thermostat. If you desire cooling, make sure that the temperature control selector is set below room temperature and the SYSTEM or MODE control is set to COOL or AUTO. If you require warmth, make sure that the temperature control selector is set above room temperature and the SYSTEM or MODE control is set to HEAT or AUTO. The FAN control should be set to ON for continuous blower operation or AUTO if you wish blower to function only while your heat pump is operating. If your comfort system still fails to operate, turn your system off and contact your servicing dealer for trouble- shooting and repairs. Specify your apparent problem, and state the model and serial number of your equipment. (You should have them recorded on the last page of this booklet.) With this information, your dealer may be able to offer helpful suggestions over the phone or save valuable time through knowledgeable preparation for the service call.
