TROUBLESHOOTING

Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).

In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the elec-
trical breaker, 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 to ensure that power is completely off.

Before requesting service, perform the following checks:

WARNING!

Symptom

Doesn’t operate immedi-
ately:

Noise is heard:

Odor:

Mist or steam are
emitted:

Airflow is weak or stops:

Water is produced from
the outdoor unit:

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 is disconnected and then recon-
nected, 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.

*

During Heating operation, a swoosh sound may be heard occa-
sionally. This sound is produced by the Automatic Defrosting op-
eration.

Occasionally an odor may be emitted from the indoor unit. This
may be the result of room odors (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.

*

When Heating operation is started, fan speed is temporarily very
low, to allow internal parts to warm up.

*

During Heating operation, if the room temperature rises above
the thermostat setting, the outdoor unit will stop, and the indoor
unit will operate at very low fan speed. If you wish to warm the
room further, set the thermostat for a higher setting.

*

During Heating operation, the unit will temporarily stop opera-
tion (between 7 and 15 minutes) as the Automatic Defrosting mode
operates. During Automatic Defrosting operation, the OPERATION
indicator light will flash.

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

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

*

During Heating operation, water may be produced by the out-
door unit due to Automatic Defrosting operation.
