Smells:
Mist or steam are
emitted:

Water is produced from

During operation and immediately after stopping the unit, the
sound of water flowing in the air conditioners piping may be
heard. Also, noise may be particularly noticeable for about 2 to 3
minutes after starting operation (sound of coolant flowing).
*During Heating operation, a sizzling sound may be heard occa-
sional. This sound is produced by the Automatic Defrosting op-
eration.
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, 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 units 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 is temporarily stop, to al-
low internal parts to warm up.
*During Heating operation, if the room temperature rises above
the thermostat setting, the indoor and the outdoor unit will stop.
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 2 and 16 minutes) as the Automatic Defrosting mode
operates. During Automatic Defrosting operation, DEFROST will
be shown on the remote controller display.
The fan may stop when the unit is monitoring the rooms tem-
perature.
*During Heating operation, water may be produced from the out-
door unit due to Automatic Defrosting operation.

Items to check
Has there been a power failure?
Has a fuse blown out, or a circuit breaker been tripped?
Is the timer operating?
Is the air filter dirty?
Are the air conditioners intake grille or outlet port blocked?
Did you adjust the room temperature settings (thermostat) cor-
rectly?
Is there a window or door open?
In the case of Cooling operation, is a window allowing bright sun-
light to enter? (Close the curtains.)
In the case of Cooling operation, are there heating apparatus and
computers inside the room, or are there too many people in the
room?
If the problem persists after performing these checks, or if you notice burning smells, stop operation immediately, turn off the
