6. MAINTENANCE
• Before washing the air filter, stop the unit operation and turn off the circuit breaker.
The fan rotates at high speed may cause injury.
• Do not wash the unit with water.
Water may cause short circuit or electric shock.
• When cleaning the air filter, ensure that you have a good footing.
If you are standing on a ladder or other types of platform, ensure that it is secured to avoid accident.
Removing the air filter
1 Open the inlet grille.
Press the knobs (two) on the ends of the grille
inward and pull down the grille.
2 Remove the air filter.
1Grasp the air filter’s grip and pull it towards you.
2Pull downwards.
Installing the air filter
1 Insert the air filter to the hooks of the grille for fixing (4 positions).
2 Close the suction grille in the reverse order of the above steps 1 and 2.
NOTE
Do not operate the air conditioner with the air filter removed. Otherwise, dirt will be accumulated
and cause damages to the air conditioner occasionally.
Cleaning the inlet air filter
Indication for cleaning;
• For wired remote control...
“FILTER CLEAN” will appear on the remote control display.
• For wireless remote control...
the filter indicator on the ray receiver will illuminate.
• Use vacuum cleaner or water to clean the air filter.
When the air filter is very dirty
Soak the filter in lukewarm water (45° or below) with mild
detergent.
Cleaning the outer cover
• Wipe with a dry soft cloth or a cloth slightly moistened with
water or neutral detergent solution.
End of season cleaning
• Clean the filter and the body of both the indoor and outdoor
units.
• Turn off the circuit breaker.
The unit contains a crank case heater to protect the
compressor. When the unit is not in use for a long period
of time, turn off the circuit breaker (the heater consumes
25 to 40 watts of electricity per hour).
Before starting the air conditioner for the first time in the season
• Check that the inlet and outlet vents of both the indoor and
outdoor units are not blocked.
• Check that the ground wire is connected and is in good
condition.

7. PROPER USE
Avoid direct sunlight while cooling
Close the windows’ curtains or blinds.
Do not block the airflow
Do not place anything near to the inlet
and outlet vents.
Blocking the airflow will reduce the
unit’s efficiency.
Do not cool or heat excessively
This will save energy and electricity.
8. TROUBLESHOOTING
• If abnormal operations (burning smell etc.) occur, stop the
air conditioner and disconnect the power supply.
Continuous operation may damage the unit or cause electric
shock or fire.
Please engage an authorized dealer.
• Do not try to repair the air conditioner by yourself.
Improper repairs may cause electric shock or fire. Please
engage an authorized dealer.
CAUTION
!
Check the following before calling for servicing
Problem

on the power.
Cause
• Is there a power outage?
• Is the circuit breaker on?
• Are the wireless remote control’s
batteries weak?
Do not use other heating equipments in the same room
while operating the unit
Using heating equipment will reduce the unit’s cooling
efficiency.
Do not leave the doors or windows open for a long period
of time.
The airflow will reduce the unit’s efficiency.
Cleaning the air filter
Use a vacuum cleaner or water to clean
the air filter.
Clogged air filter will reduce the unit’s efficiency.
Solution
Turn off the operation button once, then
turn it on again.
If the circuit breaker is off, turn it on.

Symptom
Indoor unit does not operate
immediately when the air conditioner
is restarted.
Sound of running water can be heard
during operation.
Creaking noise can be heard when
start or stop the operation.
The room has a peculiar odour
during operation.
Mist is emitted during cooling
operation (at places where large
quantities of oil is used.)
Dew formed near the outlet vents
during cooling.
The unit switches to FAN operation
and the air become humid.
The air being blown out is cool.
The air conditioner starts
automatically when the power
resumed after a power failure.
Airflow does not start immediately
after operation is started.
(“PRE HEAT” appears in the remote
control display.)
Operation stops occasionally.
(“DEFROST” appears in the remote
control display.)
Operation does not stop immediately
after you pressed the OFF/ON
button.
Changes in fan speed.
During heating, some noise may be
heard.
During heating, steam is emitted
occasionally.
Outdoor unit (Heat Pump type only)
Cause
•Once the air conditioner is stopped, it will not be operated for approximately 3
minutes. This is to protect the unit.
•This is caused by the refrigerant flowing inside the unit.
•This is caused by the panel expanding or contracting due to the changes in
temperature.
•This may be a dump smell emitted by the walls, carpet, furniture or clothing in
the room.
•The cold airflow causes the oil vapour etc. to condense.
•The cold airflow causes the moisture in the air to condense.
•This happens when the room temperature reaches the set temperature,
operation switches to FAN mode and the humidity increases.
•This is because cooling operation is running in a low fan speed. If operating the
indoor unit for a long period of time, use dry operation to lower the humidity.
•This is a normal operation as there is a auto restart operation function. The
operation will resume based on the previous settings.
•The unit is warming up to provide warm air.
Wait until the unit is warmed up.
•The system is defrosting because frost has formed in the outdoor unit.
This process can take up to 12 minutes to complete. Please wait for a while.
•This is because the unit is discharging heat.
Operation will stop automatically after approximately 60 seconds.
•When the room warms up and the temperature reaches the remote control set
temperature, the fan speed will switch to LOW and STOP automatically.
When the room temperature drops again, the fan speed will return to the remote
control settings.
•This is due to the changes in flow of refrigerant gas when operation stops and
starts.
•Due to the frosted heat exchanger, the defrost operation will begin.
During heating operation (Heat Pump type only)
The following symptoms does not indicate a malfunction
