OPERATING INSTRUCTIONS
How the air conditioner works
AUTO operation
• When the air conditioner is set to AUTO mode, it will
automatically select cooling, heating (cooling/heating
models only), or fan-only operation depending on
what temperature you have selected and the room
temperature.
• The air conditioner will control room temperature
automatically depending on the temperature set by you.
• If the AUTO mode is uncomfortable, you can select
desired conditions manually.
SLEEP operation
When the SLEEP button is pressed on remote controller
during cooling, heating (cooling & heating models only),
or AUTO operation, the air conditioner will automatically
increase (cooling) or decrease (heating) at the rate of 1ºC
per hour for the first 2 hours, then hold steady for the next
5 hours. After that it will switch off. This characteristic saves
energy and maintains comfort levels during night operation.
DRYING operation
• The fan speed will be automatically controlled under dry
operation.
• During the dry operation, if the room temperature is
lower than 10ºC, the compressor stops operation and
restarts once the room temperature rises above 12ºC.
Optimal operation levels
To achieve optimal performance, please note the following;
• Adjust the air flow direction correctly so that it is not
directed on people.
• Adjust the temperature to achieve the highest comfort
level. Do not adjust the unit to excessive temperature
levels.
• Close doors and windows on COOL or HEAT modes or
performance may be reduced.
• Use TIMER ON button on the remote controller to select a
time you want to start your air conditioner.
• Do not put any object near the air inlet or outlet, as the
efficiency of the air conditioner may be reduced and the
air conditioner may stop running.
• Clean the air filter periodically, otherwise cooling or
heating performance may be reduced.
• Do not operate unit with horizontal louvre in closed
position.

then dry it up in cool place.
CARE AND MAINTENANCE
CAUTION
• A cloth dampened with cold water may be used on
the indoor unit if it is very dirty. Then wipe with a dry
cloth.
• Do not use a chemically treated cloth or duster to
clean the unit.
• Do not use benzene, thinner, polishing powder or
similar solvents for cleaning. These may cause the
plastic surface to crack or deform.
• Never use water hotter than 40ºC to clean the front
panel as it could cause deformation or discolouration. Filter Handle
CARE AND MAINTENANCE
4. Remove the Air Freshening Filter from its support frame
(on some models).
(The optional filter includes: Plasma Dust Collector/Silver Ion
filter/Bio filter/Vitamin C filter/3M air purifier filter, etc. The
removing and installation methods are slightly different, see
the pictures marked 1 and 2 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 cool place.
Do not touch the Plasma Dust Collector Filter
within 10 minutes after opening the front panel – it
may cause an electric shock.
5. Insert 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.
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.
Maintenance
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 controller.
3. The outdoor unit requires periodic maintenance and
cleaning. Do not attempt to do this yourself. Contact your
dealer or service provider.
Checklist before operation:
• Check that the wiring is not broken, loose or
disconnected.
• Check that the air filter is installed correctly.
• Check that the air outlet or inlet is not blocked after the
air conditioner has not been used for a long time.

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 started.
b) Defrosting.
c) Low temperature heating.
• The indoor or outdoor fan stops running when
defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models only)
• 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 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 generate 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 generate due to moisture
generated from defrosting process when the air
conditioner restarts in HEAT mode operation after
defrosting.
3. Low noise emitted from 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.
• You can also hear a low “squeak” sound when
the compressor is running or has just stopped
running. This is caused by heat expansion and cold
contraction of the plastic parts in the unit when the
temperature is changing.
• A noise may be heard due to louvre returning to its
original position when power is first turned on.
4. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has
not been used for a long time or during first use of the
unit.
5. A peculiar smell comes out 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 air conditioner, the compressor will stop
automatically, and the air conditioner turns 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) to the set point.
7. Dripping water may accumulate on the surface of the
indoor unit when cooling in a high relatively humidity
(relative humidity higher than 80%). Adjust the horizontal
louvre to the maximum air outlet position and select
HIGH fan speed.
8. Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor
unit and releases it via the indoor unit during heating
operation. When the outdoor temperature falls, heat
drawn in by the air conditioner decreases accordingly.
At the same time, heat loading of the air conditioner
increases due to larger difference between indoor and
outdoor temperature. If a comfortable temperature can’t
be achieved by the air conditioner, we suggest you use a
supplementary heating device.
OPERATING TIPS
9. Auto-restart function
Power failure during operation will stop the unit
completely.
• For the unit without Auto-restart feature, when the
power restores, the OPERATION indicator on the
indoor unit starts flashing. To restart the operation,
push the ON/OFF button on the remote controller. For
the unit with Auto-restart feature, when the power
restores, the unit restarts automatically with all the
previous settings preserved by the memory function.
• For some models, the machine is specially designed
with an Auto-restart function for the open angle of
the horizontal louvre. Power failure during operation
or pressing the ON/OFF button on the remote
controller will stop the unit completely. When the
power restores or pressing the ON/OFF button
on the remote controller again, the unit restarts
automatically with all the previous settings including
the open angle of the horizontal louvre by virtue of
the memory function. We strongly suggest that the
open angle of the horizontal louvre should not be set
too small, in case condensed water forms and drops
from the horizontal louvre. Press the AUTO/COOL
button under the front panel and the open angle of
the horizontal louvre will be restored to the standard
angle when the condensed water forms on the
horizontal louvre.
10. Lightning or a car mobile phone operating nearby may
cause the unit to malfunction.
Disconnect the unit from the power source and then
re-connect the unit again. Push the ON/OFF button on
the remote controller to restart operation.
