BEFORE CALLING FOR SERVICE
The following conditions do not denote equipment malfunctions
UNIT DOES NOT OPERATE
The unit will not operate if it is turned on
immediately after it is turned off. The unit will not
operate immediately after the mode is changed.
This is to protect the internal mechanisms. Wait 3
minutes before operating the unit.
CRACKING NOISE
The unit may produce a cracking noise. This sound
is generated by the friction of the front panel and
other components expanding or connecting due to
a temperature change.
If the unit appears to be malfunctioning, check the following points before calling for
service.
IF THE UNIT FAILS TO OPERATE
• Check to see if the circuit breaker has tripped or the fuse has blown.
• Check if the louver unit is properly installed. All lamps on the indicator panel will blink when
the louver unit is not properly installed.
IF THE UNIT FAILS TO COOL THE ROOM EFFECTIVELY
Check the filters. If dirty,
clean them. Check the outdoor unit to
make sure nothing is blocking
the air inlet or outlet. Check the thermostat is
proper setting.
Make sure windows and
doors are closed tightly. A large number of people in
the room can prevent the unit
from achieving the desired
temperature.
Check whether any heat-
generating appliances are
operating in the room.
ODORS
Carpet and furniture odors that entered into the
unit and the air conditioner's inner component
odors at the early stage of installation may be
sent out from the unit.
SWISHING NOISE
The soft, swishing noise is the sound of
the refrigerant flowing inside the unit.
WATER VAPOUR
In the COOL and DRY operation, water
vapour can sometimes be seen at the
air outlet due to the difference between
the room air temperature and the air
discharged by the unit.
Please call for service when OPERATION Lamp and TIMER Lamp on the indicator panel blink.
ODOR EMITTED FROM THE
PLASMACLUSTER AIR OUTLET
This is the smell of ozone generated
from the Plasmacluster ion generator.
The ozone concentration is very small,
posing no adverse effect on your health.
The ozone discharged into the air rap-
idly decomposes, and its density in the
room will not increase.
A LOW BUZZING NOISE EMITTED
This is a sound emitted when the unit is generating
Plasmacluster ions.
