OPERATION TIPS
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
The compressor can't restart for 3 minutes after it stops.
Anti-cold air
(Cooling and heating models only)
The unit is designed not to blow cold air on HEAT mode, when the indoor heat
exchanger is in one of the following three situations and the set temperature has not
been reached.
A) When heating has just start
ed
.
B) Defrosting.
C) Low temperature heating.
The indoor or outdoor fan
will
stop running when defrosting (Cooling and heating
models only).
Defrosting
(Cooling and heating models only)
Frost may be generated on the outdoor unit during
the
heat cycle when outdoor temperature
is low and humidity is high
. This will
result in lower heating efficiency of the air conditioner.
During this condition air conditioner will stop heating operation and start defrosting
automatically.
The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature
and the amount of frost build up on the outdoor unit.
2. A white mist coming out from the indoor unit
A white mist may
appear
due to a large temperature difference between
the
air
-
inlet
s
and
air
-
outlet
s
on COOL mo
de when there is
high relative humidity
indoors
.
A white mist may
appear
due to moisture from
the
defrosting process
if the air
conditioner restarts in HEAT mode after defrosting.
3. Low noise of the air conditioner
You may hear a low hissing sound when the compressor is running or has just stopped
running. This sound is the
refrigerant flowing or coming to a stop.
You can also hear a low "squeak" sound when the compressor is running or has just
stopped running. This is caused by
the
heat expansion
and/or
cold contraction of the
plastic
parts in
side
the unit when the temperature is changing.
A noise may be heard due to louver restoring to its original position when power is first
turned on.
4. Dust is blown out from the indoor unit.
This is a normal when the air conditioner has not been used for a long time or
during first use of the unit.
5. A peculiar smell comes from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, from
furniture, or smoke.
6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and
heating models only) mode.
When indoor temperature reaches the temperature setting on
the unit
, the compressor
will stop automatically and
switch
to FAN only mode. The compressor will start again
when the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling
and heating models only).
CARE AND MAINTENANCE
Maintenance
Checks before operation
If you plan to idle the unit for a long time, perform
the following:
(1) Operate the fan for about half a day to dry the
inside of the unit.
(2) Stop the air conditioner and disconnect power.
Remove the batteries from the remote control.
(3) The outdoor unit requires periodic maintenance
and cleaning. Do not attempt to do this yourself.
Contact your dealer or servicer.
Check that the wiring is not broken or
disconnected.
Check that the air filter is installed.
Check
that
the air
-
outlet
s
or
air-
inlet
sare not
blocked after the air conditioner has not been
used for a long time.
Do not touch the metal parts of the unit when
removing the filter. Injuries can occur when
handling sharp metal edges.
Do not use water to clean inside the air conditioner.
Exposure to water can destroy the insulation,
and also
lead to possible electric shock.
When cleaning the unit, first make sure that the
power and circuit breaker are turned off.

purifier filter, etc. The removing and installation
methods are slightly different, see the pictures
marked and on the left.
Clean the air freshening filter at least once a
month and replace it every 4-5 months.
Clean it with vacuum cleaner, then dry
(if
necessary)
.
5. Install the air freshening filter back into position.
6. Insert the upper portion of air filter back into the
