BEFORE CALLING FOR SERVlCE

IF YOUR AIR CONDITIONER DOES NOT OPERATE PROPERLY, PLEASE CHECK THE FOLLOWING ITEMS BEFORE CALLING FOR SERVICE.

AIR CONDITIONER DOES NOT OPERATE AT ALL

•Is the unit plugged in or is the plug loose?

•Is the fuse blown or the circuit breaker tripped?

•Did you restart the unit within 3 minutes after a power failure? If the power was off for less than 3 minutes, and you restarted the air conditioner within 3 minutes, a protective device may cause the compressor to shut off, preventing cooling for about 5 minutes.

AIR CONDITIONER DOES NOT PROPERLY COOL

•Is the SELECTOR set to fan only (HIGH FAN, MED FAN, LOW FAN)mode? Cooling will not take place in the fan only mode. Change the SELECTOR setting.

•Is the filter clogged with dust?

A dirty filter can cause the cooling coils to freeze. If this happens, clean the filter and replace. Run the air conditioner on the MED FAN setting until all ice dissipates.

•Is the temperature set properly?

If your room is too warm, adjust the temperature setting lower. If your room is too cool, adjust the temperature setting higher.

•Is the EXHAUST lever in the OPEN position.?

The lever should be in the CLOSED position during cooling.

•Is the window exposed to direct sunlight?

Close curtains or blinds to minimize solar energy heating the room.

•Are the windows or doors open?

Close all windows and doors for maximum cooling.

TIMER DOES NOT WORK PROPERLY

•If a power failure occurs while the ON or OFF TIMER is set, the TIMER setting will be cancelled and will not resume even after the power is reinstated. This is the normal operation for this unit.

NOTE: WATER IN BOTTOM OF TRAY

•Water will collect in the bottom tray of the unit. This is normal. Water condenses on the evaporator coil at the front of the unit and is channeled to the rear where it is picked up by the condenser fan. The water is blown onto the condenser coil fins and this creates a "splashing" noise which is normal. If excess water builds up in this tray it will drain outside through a grooved channel in the tray.

SOUNDS

•The operating sound may seem rather loud for 2 to 3 minutes when the unit is first turned on. This is the sound of the compressor's start-up and is normal.

•A soft, swishing noise can be heard immediately after the unit is turned on or off, and also during operation. This is the sound of the refrigerant flowing inside the unit.

IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL

•Check the remote control batteries. Replace if necessary.

•Try to send the signal again with the remote control pointed directly at the unit's receiver window.

•Check whether the remote control batteries are installed with the polarities properly aligned.
