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 power cord loosened or unplugged?
• Is the fuse blown or has the circuit breaker been tripped?
• Did you restart the unit within 3 minutes after power failure? If the power was off for less
than 3 minutes, and you restart the air conditioner within 3 minutes, a protective device
may cause the air conditioner to shut off, preventing cooling operation for about 20
minutes.
AIR CONDITIONER DOES NOT COOL PROPERLY
• Is the SELECTOR set to LOW FAN or HIGH FAN?
Cooling will not be conducted in LOW FAN and HIGH FAN . Change the SELECTOR
setting to LOW COOL or HIGH COOL.
• Is the filter covered with heavy dirt?
A dirty filter can cause the cooling coils to freeze. If this happens, clean the filter and
replace it. Run the air conditioner on the HIGH FAN setting until it defrosts.
• Is the THERMOSTAT set properly?
If your room is too warm, adjust the THERMOSTAT knob to a higher cooling setting.
If your room is too cool, adjust the THERMOSTAT knob to a lower cooling setting.
• Is the VENTILATION lever set in the RIGHT (OPEN) position?
The lever should be set in the LEFT (CLOSED) position during cooling operation.
• Are the windows exposed to direct sunlight?
Close curtains or blinds to minimize the heat in the room.
• Are the windows or doors open?
Close all windows and doors for maximum cooling effect.
LEFT / RIGHT AIR FLOW ADJUSTMENT LOUVRES DO NOT SWING
• Is the crank shaft fitted properly into the louvre link?
Remove the front panel, and replace it again. Make sure to slide the crank shaft into
the opening of the louvre link at the back of the front panel. (See page 4, step 6-(3))
• Is the SELECTOR set to LOW FAN or HIGH FAN? The auto swing louvre can be
activated only at LOW COOL or HIGH COOL setting.
