When outdoor temperature is low and humidity is high, the unit some-
times performs defrosting automatically. Please wait. During defrost-
ing, water or steam may escape from the outdoor unit.
Air is not blown out when starting the DRY operation.
(RUN light is on)
The indoor fan may stop to prevent re-evaporation of dehumified
moisture and to save energy.
Some steam escapes during COOL operation.
This may occur if the room's temperature and humidity are very high.
It disappears as soon as the temperature and humidity decrease.
If the unit is operated for a long time in high humidity, moisture may
form on the air outlet grilles and start dripping.
There is a slight smell. Air blown out during operation may smell. This is caused by tobacco
or cosmetics sticking to the unit.
You hear a slight gurgling sound. This is caused by refrigerating liquid moving within the unit.
You hear a slight cracking sound. This is caused by heat expansion or contraction.
Remote control signals may not be received if the signal receiver on
the air conditioner is exposed to direct sunlight or other bright light.
If so, cut out the sunlight or reduce the other light.
After a power cut, you cannot re-start, even if power has been re-
stored, unless you have the power blackout auto restart function.
The memory circuit of the microcomputer has been wiped out. Use the
remote control to start the operation again.
Remote control signals are not received.
Moisture may form on the air outlet grilles.
The noise means that the revolution speed is picking up on the com-
pressor.
Whistling noise is heard from the outdoor unit.
This is the sound when operation of another indoor unit is stopped.Sometimes a “Shooooo” sound might come for a short time
from the unit that is turned off.
If one unit is operating in COOL mode while another is in operating in
HEAT or any other different operation mode, FAN mode operation
will be implemented. Individual operation modes need to be matched.
FAN operation will be performed even if COOL, DRY, or
HEAT have been selected.
Restarting has been blocked for 3 minutes after you have stopped or
after switching off the power during operation, to protect the unit.
The three-minute protection timer in the microcomputer automatically
starts up again.
Please wait for
three minutes.
