Having trouble?
Here is the solution. (Unit is operating normally.)
Air conditioner does not heat or cool well.
■
&OHDQWKH¿OWHU$LUÀRZLVUHGXFHGZKHQWKH¿OWHULVGLUW\RUFORJJHG
■
Check the temperature adjustment and adjust the set temperature.
■
Make sure that there is plenty of space around the outdoor unit. Is the
indoor unit air intake or outlet blocked?
■
Has a door or window been left open?
When heating operation starts, warm air does not blow from the indoor
unit soon.

During heating mode, the air conditioner stops before the set room tem-
perature is reached.
■
When the outdoor temperature is low and the humidity is high, frost
may form on the outdoor unit. If this occurs, the outdoor unit performs a
defrosting operation. Normal operation should begin after approximately
10 minutes.
During cooling mode, the air conditioner stops when the set room tem-
perature is reached.
■
For SLZ-M·FA series, when the set room temperature is reached during
cooling mode, the fan operates at the lowest speed.

A cracking or creaking sound is heard.
■
These sounds can be heard when parts rub against each due to expan-
sion and contraction from temperature changes.
The room has an unpleasant odor.
■
The indoor unit draws in air that contains gases produced from the walls,
carpeting, and furniture as well as odors trapped in clothing, and then
blows this air back into the room.
A white mist or vapor is emitted from the indoor unit.
■
If the indoor temperature and the humidity are high, this condition may
occur when operation starts.

mist.
Water or vapor is emitted from the outdoor unit.
■
During cooling mode, water may form and drip from the cool pipes and
joints.
■
During heating mode, water may form and drip from the heat exchanger.
■
During defrosting mode, water on the heat exchanger evaporates and
water vapor may be emitted.
“
” appears in the remote controller display.
■
During central control, “
” appears in the remote controller display and
air conditioner operation cannot be started or stopped using the remote
controller.
When restarting the air conditioner soon after stopping it, it does not oper-
ate even though the ON/OFF button is pressed.
■
Wait approximately three minutes.
(Operation has stopped to protect the air conditioner.)
