TROUBLESHOOTING

Instructions relating to heating (*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
WARNING
Before requesting service, perform the following checks:
Symptom
NORMAL Does not operate
FUNCTION immediately:
Noise is heard:
Smells:
Mist or steam are
emitted:
In following events, immediately stop operation of the air conditioner, and disconnect all the power sup-
ply by turning off the electrical breaker or disconnecting the power plug. Then consult your dealer or
authorized service personnel.
As long as the unit is connected to the power supply, it is not insulated from the power supply even if
the unit is turned off.
• Unit smells of something burning or emits smoke
• Water leaks from the unit
If the unit is stopped and then immediately started again, the compressor will
●
not operate for about 3 minutes, in order to prevent fuse blowouts.
Whenever the power supply plug is disconnected and then reconnected to a
●
power outlet, the protection circuit will operate for about 3 minutes, prevent-
ing unit operation during that period.
During operation and immediately after stopping the unit, the sound of water
●
fl owing in the air conditioner's piping may be heard. Also, noise may be par-
ticularly noticeable for about 2 to 3 minutes after starting operation (sound of
coolant fl owing).
During operation, a slight squeaking sound may be heard. This is the result
●
of minute expansion and contraction of the front panel due to temperature
changes.
* During heating operation, a sizzling sound may be heard occasionally. This
●
sound is produced by the automatic defrosting operation.
Some smell may be emitted from the indoor unit. This smell is the result of
●
room smells (furniture, tobacco, etc.) which have been taken into the indoor
unit.
During cooling or dry operation, a thin mist may be seen emitted from the
●
indoor unit. This results from the sudden cooling of room air by the cool air
emitted from the indoor unit, resulting in condensation and misting.
* During heating operation, the outdoor unit's fan may stop, and steam may be
●
seen rising from the unit. This is due to the automatic defrosting operation.
