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.
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.
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.
INDOOR UNIT BECOMES WARM
EVEN WHEN IDLE
This is because the refrigerant also floes
through the idle indoor unit's pipes when the
other unit is operated in HEAT mode.
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.
Make sure windows and doors
are closed tightly.
IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL
Check whether the remote con-
trol batteries have become old
and weak.
Please call for service when TEMPERATURE INDICATOR on the indicator panel blink.
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.
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.
UNIT DOES NOT OPERATE IN YOUR
REQUESTED MODE
• When one indoor unit is operating in COOL or DRY
mode, you can not operate the other unit in HEAT
mode. (After a few seconds, a long BEEP will be
emitted, and the temperature indicator on the indica-
tor panel will indicate"
lamp and TIMER lamp will blink alternately.)
• When one indoor unit is operating in HEAT mode,
you can not operate the other unit in COOL nor DRY
mode. (After a few seconds, a long BEEP will be
emitted, and the temperature indicator on the indica-
tor panel will indicate"
lamp and TIMER lamp will blink alternately.)
Check the outdoor unit to make
sure nothing is blocking the air in-
let or outlet.
A large number of people in the
room can prevent the unit from
achieving the desired tempera-
ture.
Try to send the signal again with
the remote control pointed prop-
erly towards the unit's signal re-
ceiver window.
