TROUBLESHOOTING

WARNING!
Before requesting service, perform the following checks:
Symptom
NORMAL Doesn't operate immedi-
FUNCTION ately:
Noise is heard:
Smells:
Mist or steam are emitted:
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.
● If the unit is stopped and then immediately started again, the com-
pressor 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,
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 occasional.
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 air conditioner.
● 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 air emitted from the air conditioner, 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 Automatic Defrosting
operation.
Please buy delicated deodorizing fi lter (UTR-FA13-2) (Sold
separately) when exchanging the fi lters.
