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.
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 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 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 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 Health 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 generate on the surface of the indoor unit
when cooling in a high relatively humidity (relative humidity higher
than 80%). Adjust the horizontal louver 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.
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.
10. Lightning or a car wireless telephone operating nearby may
cause the unit to malfunction.Disconnect the unit with power and
then re-connect the unit with power again. Push the ON/OFF
button on the remote controller to restart operation.

1
Use a dry cloth to wipe the indoor unit and remote controller.
2
A cloth dampened with cold water may be used on the indoor
unit if it is very dirty.
3
Do not splash water on unit. This may cause damage to the
inner parts or an electric shock.
CAUTION
Do not use a chemical-treated duster for wiping or leave
such material on the unit for long.
Do not use benzine, thinner, polishing powder, or similar
solvents for cleaning. These may cause the plastic surface
to crack or deform.
Cleaning the air outlet
After using for a period, the air outlet and louvers will become
dirty. It is recommended to dip a soft cloth into warm water or a
mild kitchen cleanser, ring it out, then wipe any soiling from the
unit. After, wipe with a dry cloth.
4. CARE AND MAINTENANCE
Cleaning the Lower front panel and Air Filter
If the air filter becomes clogged, the performance will decrease
and electricity will be wasted.
The air filter should be checked and cleaned about once every 2
weeks to maintain optimal performance of the air conditioner.
1
The air filter is located under the lower front panel (see figure
above).
2
First take down the screw cover on both side of the panel, then
remove the screws using the screwdriver.
3
Hold both side of the panel and pull it downwards, then take it
down.
4
Take hold of the air filter holder and pull it up, and then take it
out.
5
The lower front panel can be wiped with water or
dipped water. Wash it with water and dry it in a cool place.
6
Use a vacuum cleaner to remove the dust or wash the air filter
with water, and dry it in the shadow.
7
Installation process of the air filter and lower front panel is the
reverse of the removal process.
