Your heat pump will work longer to keep your home comfortable under these conditions: 1. Entrance doors are frequently opened and closed 2. Laundry appliances are being operated 3. A shower is running 4. More than the usual number of people are present in the home 5. More than the normal number of electric lights are in use 6. Drapes are open on the sunny side of the home II. HEATING MODE With the SYSTEM or MODE control of your indoor thermostat set to HEAT, your heat pump will run in heating mode until room temperature is raised to the level you have selected. Of course, your heat pump will have to operate for longer periods to maintain a comfortable environment on cooler days and nights than on moderate ones. III. SUPPLEMENTAL HEAT Your heat pump is your primary heating source. Your system may also be equipped with a supplemental heating source such as electric heat. On cold days and nights, your system will automatically turn on the supplemental heat in order to maintain the level of comfort you have selected. —2— When your heat pump needs additional heat to keep you comfortable, your Bryant electronic thermostat will turn on the supplemental heat (if equipped) and will display the “AUX HT” message. IV. DEFROST MODE When your heat pump is providing heat to your home and the outdoor temperature drops below 45°F, 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 energy-efficient operation, your heat pump has an automatic defrost mode. The defrost mode starts at a preset time interval of 90 minutes, although, it may be reset to either 30 or 50 minutes. Defrost will start at the preset time only if the ice is sufficient to interfere with normal heating operation. After the ice is melted from the coil, or after a maximum of 10 minutes in defrost mode, the unit automatically switches back to normal heating operation. 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 accomplished easily by referring to the following directions. However, before performing maintenance, consider these important safety precautions: WARNING: 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 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 return-air duct at the outdoor unit or behind the return-air grille(s). Have your dealer show you the location of your filter(s) and the procedures for removal and replacement.
