Air is not blown out for 5 to 10 min. or blown out not warm
wind for a moment at HEATING operation.
RUN light blinks slowly
(1.5 sec ON, 0.5 sec OFF)
Please remember!
You cannot restart the unit immediately after you have
stopped it.
(RUN light is on)
Not
operating?
Air is not blown out when starting the HEATING operation.
RUN light blinks slowly
(1.5 sec ON, 0.5 sec OFF)
Air flow has stopped to prevent blowing out of cold air until the indoor
heat exchanger has warmed up. (2 to 5 min.) (HOT KEEP)
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.
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.
If the unit is operated for a long time in high humidity, moisture may
form on the air outlet grills and start dripping.
You hear a slight gurgling sound.
You hear a slight cracking sound.
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 grills.
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 hissing or clicking sound.
This is caused by the operation of the refrigerant control valves or
electric components.
The noise means that the revolution speed is picking up on the com-
pressor.
Whistling noise is heard from the outdoor unit.
Indoor fan
: Fan will not stop after 2 hours if set to CLEAN operation.
Outdoor fan : Fan will not stop about a 1 minute period in order to
protect the unit.
Fan won't stop immediately after unit operation was
stopped.
RUN light stays on even though operation was stopped.
The RUN light blinks during CLEAN operation.
Run light turns off when CLEAN operation ends.
This is caused by expansion and contraction of plastic body. Tempera-
ture change of plastic material due to compressor’s alternative opera-
tion cause a slight cracking noise.
This is caused by liquid refrigerant moving within the piping of indoor
unit. Liquid refrigerant will be evaporated and become as gaseous re-
frigerant during passing through the pipe in order to absorb the heat
inside the room.
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.
