SPECIAL OPERATION, HEATING — Outdoor cooling units may be matched with heat pump ceiling-suspended fan coil units to provide supplemental electric heat. All other operation is the same as a cooling-only system, except these units have heating capability as follows:

When the room thermostat initiates a call for heating, the electric heater is turned on. The indoor unit fan will start at the same time, if it was not already running.

When the heating requirement is satisfied, the room thermo- stat will open, and the heater will turn off.

CLEANING AND MAINTENANCE

To avoid the possibility of electric shock, before performing any cleaning and maintenance operations, always turn off power to the system by pressing the mode button on the remote thermostat until the display shows “OFF,” and turn- ing off the outdoor disconnect switch located near the out- door unit. If the indoor unit is on a separate switch, be sure to turn this disconnect off as well.

Do not wash filter in water over 120 F (to avoid shrinkage). Do not expose filter to fire (to avoid fire damage). Do not expose filter to direct sunlight. Clean filter more frequently when air is extremely dirty.

For proper system operation, perform the cleaning and maintenance operations in Table 6.

Lubrication — The indoor-fan, automatic air sweep, and the outdoor-fan motors are factory lubricated and require no oiling.

Air Filters (Fig. 23)

Operating the system with dirty air filters may damage the indoor unit and, in addition, can cause reduced cooling per- formance, intermittent system operation, frost build-up on the indoor coil, and blown fuses. Inspect and clean or replace the air filters monthly.

REMOVE AIR FILTERS — Remove filters by pulling them straight out.

CLEAN OR REPLACE FILTERS — Filters can be vacu- umed or washed in warm water. Shake filter to remove any ex- cess water, and replace by sliding filter behind grille until filter snaps in place. Refer to Fig. 23.

If the filter has begun to break down or is torn, replace it. Replacement filters are available through your dealer.
