BEFORE CALLING FOR SERVICE
If the unit appears to be malfunctioning, check the following points before calling for a ser-
vice.
UNIT DOES NOT OPERATE AT ALL
• Is the unit plugged in or is the plug loose?
• Has the fuse blown or is the circuit breaker tripped?
• Did you restart the unit within 3 minutes of a power failure?
If the power was off for less than 3 minutes when, you restarted the unit, a protective de-
vice may cause the compressor to shut off, preventing cooling for about 5 minutes.
• Are the AIR CON, TIMER and MAXIMUM lamps blinking?
The water tank inside the unit is full. It must be drained. (See page 26)
• Check the power plug. (See page 16)
UNIT DOES NOT COOL PROPERLY
• Is it set to FAN, DEHUMIDIFICATION, VENTILATION, ION GENERATOR mode?
Cooling does not take place in these modes. Change the MODE setting.
• Is the filter clogged with dust?
Clean the filter.
• Is the cooling coil frozen?
No air will blow out if the cooling coil is frozen.
Run the unit in FAN mode with the fan speed set to "HIGH" until all ice dissipates.
• Is the temperature set properly?
• Is the window exposed to direct sunlight?
Close the curtains or blinds to minimize solar energy heating the room.
• Is the exhaust hose too long?
For efficient operation, make the hose as short as possible. The exhaust hose must not
be twisted or bent.
SOUNDS
• The unit may seem rather loud for the first 2 to 3 minutes when the unit is turned on.
This is the sound of the compressor starting-up and is perfectly 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.
• A low buzzing noise is emitted when the unit is generating Plasmacluster ions.
• This unit evaporates water condensed during cooling operation within the unit through
the exhaust air outlet. Although water flowing sound way be heard, this is normal.
• An audible gurgling sound may be heard when the unit is operated on a gently sloping
floor. Place the unit on a level floor.
TIMER DOES NOT WORK PROPERLY
• If a power failure occurs while the TIMER is set, the TIMER setting will be cancelled and
will not be retrieved even after the power is restored. This is normal for this unit.
THE UNIT FAILS TO REACT TO THE REMOTE CONTROL SIGNAL
• Check the batteries in the remote control. Replace if necessary.
• Try to send the signal again with the remote control pointed directly at the unit’s signal
receiver window.
• Check whether the remote control batteries are installed with the polarities properly
aligned.
THE DISCHARGED AIR HAS AN ODOR
• Plasmacluster ion generator emits small traces of ozone which may produce an odor.
These ozone emissions are below safety levels and comply with the federal ozone
emissions limit.
