TROUBLESHOOTING

WARNING!
Before requesting service, perform the following checks:
Symptom
NORMAL Doesn't operate immedi-
FUNCTION ately:
Noise is heard:
Smells:
Mist or steam is emitted:
In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the Power
Supply Plug, and consult authorized service personnel.
Merely turning off the indoor unit's power switch will not completely disconnect the unit from the power
source. Always be sure to disconnect the Power Supply Plug or turn off your circuit breaker to ensure
that power is completely off.
● If the indoor 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 recon-
nected to a power outlet, the protection circuit will operate for about
3 minutes, preventing unit operation during that period.
● During operation or 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 refrigerant 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 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 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 conden-
sation and misting.
● During Heating operation, water may be produced from the outdoor
unit due to Automatic Defrosting operation.
