TROUBLESHOOTING

In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the

WARNING! 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 disconnect the Power Supply Plug or turn off your circuit breaker to ensure that power is completely off.

Before requesting service, perform the following checks:

ately:

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.

 

 

 

 

 

 

Noise is heard:

● 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.

 

 

 

 

 

 

Smells:

● 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.

 

 

 

 

 

 

Mist or steam are

● During Cooling or Dry operation, a thin mist may be seen emitted

 

 

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.

 

 

 

 

 

 

Airflow is weak or stops:

● The fan may operate at very low speed during Dry operation or

5

 

 

when the unit is monitoring the room’s temperature.

 

 

 

 

 

 

 

 

 

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

5

 

 

speed.

 

 

 

 

 

 

 

 

 

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

5

 

 

speed.
