TROUBLESHOOTING

WARNING!
Before requesting service, perform the following checks:
NORMAL Doesn't operate immedi-
FUNCTION ately:
Noise is heard:
Smells:
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical
breaker or disconnect the power supply plug, and consult authorized service personnel.
Merely turning off the unit's power switch will not completely disconnect the unit from the power source.
Always be sure to turn off the electrical breaker or disconnect the power supply plug to ensure that
power is completely off.
Symptom
● 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 re-
connected to a power outlet, the protection circuit will operate for
about 3 minutes, preventing 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 particularly 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 cover
due to temperature changes.
● During Heating operation, a sizzling sound may be heard occa-
sional. This sound is produced by the Automatic Defrosting opera-
tion.
● 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 air conditioner.
