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.
UNIT DOES NOT SEND OUT WARM AIR
The unit is preheating or de-icing.
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 COOL (OR HEAT) 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 compo-
nent 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.
• In the HEAT operation, water vapour may
flow out of the outdoor unit during de-icing.
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 ionizer. Density of the ozone is very
little, having no adverse effect over your
health. The ozone released into the air will
decompose soon, and its density in the
room will not increase.
IF THE UNIT FAILS TO OPERATE
• Check to see if the circuit breaker has tripped or the fuse has blown.
• Check if the louvre unit is properly installed. All lamps on the indicator panel will blink when
the louvre unit is not properly installed.
A LOW BUZZ NOISE EMITTED
This is a sound emitted when the unit is
generating Plasmacluster ions.
THE OUTDOOR UNIT DOES NOT STOP
After stopping the operation, the outdoor
unit will rotate its fan for about a minute to
cool down the unit.
