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 inlet or
outlet. Check the thermostat is
for 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 temeperature. 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 in-
stallation 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 va-
pour may flow out of the outdoor
unit during de-icing.
