Symptom

G 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.

G 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.

*G During Heating operation, the outdoor unit's fan may stop, and

steam may be seen rising from the unit. This is due to the Auto-

matic Defrosting operation.

*G When Heating operation is started, fan speed is temporarily very

low, to allow internal parts to warm up.

*G 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 to a higher setting.

*G During Heating operation, the unit will temporarily stop opera-

tion (between 7 and 15 minutes) as the Automatic Defrosting mode

operates. During the Automatic Defrosting operation, the OPERA-

TION indicator lamp will flash.

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

when the unit is monitoring the room's temperature.

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

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

speed.

*G During Heating operation, water may be produced from the out-

door unit due to the Automatic Defrosting operation.

G Clean the filter. Afterwards, turn the FILTER lamp off.

G Has the circuit breaker been turned off?

G Has there been a power failure?

G Has a fuse blown out, or a circuit breaker been tripped?

G Is the timer operating?

G Is the air filter dirty?

G Are the air conditioner's intake grille or outlet port blocked?

G Did you adjust the room temperature settings (thermostat) cor-

rectly?

G Is there a window or door open?

G In the case of Cooling operation, is a window allowing bright sun-

light to enter? (Close the curtains.)

G In the case of Cooling operation, are there heating apparatus and

computers inside the room, or are there too many people in the

room?

G Is the unit set for QUIET operation?

G Are the remote control unit's batteries dead?

G Are the remote control unit's batteries loaded properly?

G Are you using an air conditioner signal code other than signal

code A?
