Cleaning the air filter
NOTE: Supply power must be disconnected before cleaning
the indoor unit.
A clogged air filter reduces the cooling efficiency of this unit.
Please clean the filter every month or more often if necessary.
1
Lift the indoor unit front panel up to an angle until it
stops with a clicking sound.
2
Take hold of the handle of the air filter and lift it up
slightly to take it out from the filter holder, then pull
it downwards.
3
Remove the AIR FILTER from the indoor unit. Clean the
AIR FILTER with a vacuum cleaner or water, then dry it
in cool place.
4
Remove the Air Freshening Filter from its support frame
Optional Filters: Plasma Duster Collector / Silver Ion
Filter / Bio Filter / Vitamin C Filter / 3M air purifier Filter
from its support frame.
(There is slight difference on installation/removing the
filter, 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 a vacuum cleaner, then dry it in a cool place.
warning
Do not touch the Plasma Dust Collector Filter within 10
minutes after opening the front panel, it may cause an
electric shock.
5
Install the air freshening filter back into position.
6
Insert the upper portion of air filter back into the unit,
taking care that the left and right edges line up correctly
and place filter into position.
Maintenance
If the air conditioner is not going to be used for some period
of time:
1
Let the fans run for 3~4 hours to allow the device to
completely dry out.
2
Switch off the device and pull the power plug. 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.
Checks before operation
•
Check that the wiring is not broken off or disconnected.
•
Check that the air filter is installed.
•
Check if the air outlet or inlet is blocked after the air
conditioner has not been used for a long time.

caution
•
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, leading to
possible electric shock.
•
When cleaning the unit, first make sure that the power
and circuit breaker are turned off.
Troubleshooting Tips
Before you contact customer service, check the
following first:
The air conditioner does not start. Check the following:
1
Is voltage present at the plug socket outlet?
2
Check the plug fuse!
3
Is the timer set?
The air conditioner does not provide satisfactory cooling.
Check the following:
1
Has an appropriate temperature been set?
2
Is the air filter soiled? Clean and fit back in place.
3
Are the inlets and outlets on the outdoor unit blocked?
4
Are the doors and windows closed?
The remote control does not work. Check the following:
1
Important! It only works within a range of 8m from the
indoor unit.
2
Are the batteries still OK? Replace if necessary!
3
Have the batteries been inserted correctly? Check that
the + and - terminals are in the correct positions!
Stop the air conditioner immediately if one of the following
faults occur. Disconnect the power and contact your
service center.
1
Fuse blows frequently or circuit breaker trips frequently.
2
Other objects or water penetrate the air conditioner.
3
If one of the malfunction codes appears on the LED
display window: E0, E1, E2, E3, E4, E5, F0, F1, F2, F3, F4,
F5, P0, P1, P2, P3 or P4.

NOTE: When more than one malfunction occur, pressing any
button on the remote control will display the error
codes in sequence, and the unit will respond by a
beep for each press.

Other abnormal situations.
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
•
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 starting.
B) Defrosting.
C) Low temperature heating.
•
The indoor or outdoor fan stop running when defrosting.
Defrosting
•
Frost may be generated on the outdoor unit during
heat cycle when outdoor temperature is low and
humidity is high resulting in lower heating efficiency
of the air conditioner.
•
During this condition the 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 buildup on the outdoor unit.
2
A white mist coming out from the indoor unit
•
A white mist may be generated due to a large
temperature difference between air inlet and air outlet
on COOL mode in an indoor environment that has a high
relative humidity.
•
A white mist may be generated due to moisture
generated from the defrosting process when the
air conditioner restarts in HEAT mode operation
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 sound of the refrigerant flowing or
coming to a stop.
