TROUBLESHOOTING

WARNING!

Symptom

Doesn’t operate immedi-
ately:

Noise is heard:

Smells:

Mist or steam are
emitted:

Airflow is weak or stops:

Problem

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 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 flowing 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 flowing).

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.

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.

The fan may operate at very low speed during Dry operation or
when the unit is monitoring the room’s temperature.

During SUPER QUIET operation, the fan will operate at very low
speed.

In the monitor AUTO operation, the fan will operate at very low
speed.

source. Always be sure to turn off the electrical breaker or disconnect the power supply plug to
ensure that power is completely off.
