if it is, ask your dealer to instruct you on its maintenance. Your indoor coil is equipped witk a drain pan to collect condensate formed as your system removes humidity from the inside air. Have your dealer show you where the main condensate drain (and auxiliary drain, if applicable) runs and how to check the drain for any obstruction.

Leaves, trash or skruks crowding tlie unit cause tke outdoor unit to work karder and use more energy. Keep skrukkery trimmed away from tke unit and periodically ckeck for dekris wkick may kave collected around tke unit. UNIT OPERATION Your new Lennox keat pump kas several ckaracteristics tkat you skould ke aware of: Your keat pump satisfies keating demand ky delivering large amounts of warm air into tke living space. Tkis is quite different from gas- or oil-fired furnaces or an electric furnace wkiak deliver lower volumes of considerably warmer air to keat tke space. Do not ke alarmed if you noticc frost on tke outdoor coil in tke winter montks. Frost develops on tke outdoor coil during tke keating: cycle wken temperatures are kelow 45°F (7°C). An electronic control activates a defrost cycle lasting 5 to 15 minutes at preset intervals to clear tke outdoor coil of tke frost. During tke defrost cycle, you may notice steam rising from tke outdoor unit. Tkis is a normal occurrence. Tke tkermostat may engage auxiliary keat during tke delrosfc cycle to satisfy a keating demand; kowever, tke unit will return to normal operation at tke conclusion of tke defrost cycle.

TEMPERATURE SETTING LEVERS Most heat pump thermostats have two temperature selector levers: one for heating and one for cooling. Set the levers or dials to the desired temperature setpoints for hoth heating and cooling. Avoid frequent temperature adjustment; turning the unit off and hack on before pressures equalize puts stress on the unit compressor. FAN SWITCH In AUTO or INT (intermittent) mode, the blower operates only when the thermostat calls for heating or cooling. This mode is generally preferred when humidity control is a priority. The ON or CONT mode provides continuous indoor hlower operation, regardless of whe ther the compressor or auxiliary heat are operating. This mode is required when constant air circulation or filtering is desired. SYSTEM SWITCH Set the system switch for heating, cooling or auto operation. The auto mode allows the heat pump to BEFORE YOU CALL if your systems fails to operate, check the following before calling for service: • Check to see that all electrical disconnect switches are ON. • Make sure the room thermostat temperature selector is properly set. • Make sure the room thermostat system switch is properly set. • Replace any blown fuses, or reset circuit breakers. • Make sure unit access panels are in place. • Make sure air filter is clean. • Locate unit model number and have it handy before calling. automatically switch from heating mode to cooling mode to maintain predetermined comfort settings. Many heat pump thermostats are also equipped with an emergency heat mode which locks out heat pump operation and provides temporary heat supplied by the auxiliary heat. INDICATING LIGHT Most heat pump thermostats have an amber light which indicates when the heat pump is operating in the emergency heat mode. TE...
