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?
