Fan - In this mode the fan circulates air but the compressor does not run. Use the Fan Speed button to set fan speed to High or Low. In this mode, you cannot adjust the set temperature.

Heat - This mode is ideal on cold days to heat the room quickly. Use the Temp buttons to set the desired room temperature and use the Fan Speed button to set the desired fan circulation speed.

Additional Features

Slinger Fan

This air conditioner is equipped with a slinger fan. (See drawing.)

The fan’s outer ring picks up the condensed water from the base pan if the water level gets high enough. The water is then picked up by the fan and expelled through the condenser, making the air conditioner more efficient.

Drain Pipe

In humid weather, excess water may cause the base pan to overflow. To drain the water, remove the drain cap and secure the drain pipe to the rear hole of the base pan. Press the drain pipe into the hole by pushing down and away from the fins to avoid injury

MAINTENANCE

Air Filter

Check the air filter last twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator.

Cleaning the Air Filter

1.Lift the inlet grille. Remove the air filter from the front grille by pulling it up slightly

2. Wash the filter using lukewarm water below 40 °C (104 °F).

3. Gently shake the excess water from the filter and replace.

Cleaning the Air Conditioner

●Wipe the front grille and inlet grille with a cloth dampened in a mild detergent solution.

●Wash the cabinet with mild soap or detergent and lukewarm water, then polish using liquid appliance wax.

NOTE

• To ensure continued peak efficiency, the condenser coils (outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from outside air.

• For repair and maintenance, contact an Authorized Service Center. See the warranty page for details or call 1-800-243-0000. Have your model number and serial number available. They can be found on the side of the cabinet. Record them on page 27 for future reference.
