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 OPERATE
Check to see if the circuit breaker has tripped or the fuse has blown.
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 in-
let 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 tempera-
ture.
Check whether any heat-gen-
erating appliances are operat-
ing 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.
Please call for service when OPERATION Lamp, TIMER Lamp and TEMPERATURE INDICATOR
on the indicator panel blink.
A LOW BUZZ NOISE EMITTED
This is a sound emitted when the unit is generating ion
clusters.
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 va-
pour 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.
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.
ODOR EMITTED FROM THE
PLASMACLUSTER AIR OUTLET
This is the smell of ozone generated from the
ionizer. Density of the ozone is very little, hav-
ing no adverse effect over your health. The
ozone released into the air will decompose soon,
and its density in the room will not increase.
During PLASMACLUSTER AUTO OPERATION, the air conditioner operates in the REFRESHING OP-
ERATION even when there is odor in the room.
• In case for example, when the room is full of tobacco smokes before the air conditioner is turned on, the
ODOR SENSOR may become unreactive.
