cloth.
9-2 INDOOR COIL CLEANING
It is recommended to clean the coil at least at the beginning of each cooling season or when necessary;
turn the unit off first.
• Use a vacuum cleaner or a long-bristle brush to avoid damage to the coil fins.
• Watch the fin edges to avoid injury.
• Damage to the fins may cause reduced coil efficiency resulting in increased running costs. Use
of flames, liquid or aerosol solvents must be avoided. Use of these substances will cause serious
damage to the panels and electric parts.

12. OPERATION TIPS
The following events may occur during normal operation of the air conditioner:
1. A slight white mist (water vapor)coming out from the indoor unit during cooling
ƒ 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.
The cool air from the indoor unit is coming into contact with the room air.
ƒ A white mist may generate due to moisture generated from defrosting process when the air
conditioner restarts in HEAT mode operation after defrosting.
2. Low noise of the air conditioner
ƒ You may hear a low hissing sound when the air conditioner is running or has just stopped
running.
This sound is the sound of the refrigerant beginning to circulate or an adjustment of the
refrigerant pressures after stopping.
ƒ You can also hear a low short "squeak" when the indoor unit is in operation or when it has
stopped.
These are generally due to the temperature changes on the plastic parts ( expansion or
contraction ).
A noise may be heard due to louver restoring to its original position when power is first turned on.
3. 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.
4. Unpleasant smells coming out from the indoor unit.
ƒ Unpleasant smells can be caused by substances accumulated in the air filters of indoor unit.
ƒ In this case, you must switch the system off and air filters must be cleaned.
ƒ Restart the unit in ventilation ( fan only ) mode and open windows to change the room air,
5. The air conditioner turns to FAN only mode from COOL or HEAT.
When indoor temperature reaches the temperature setting on air conditioner compressor will stop
automatically the ,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 (only for heat pump system) to the set point.
6. Dripping water may generate on the surface of the indoor unit
(when cooling in a high relatively humidity higher than 80%).
Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.
7. Heating mode For.
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.
8. Mist (water vapor) coming out from the outdoor unit during heating
It is normal in heat pump operation when defrost is automatically activated during heating operation
at very low ambient.
9. 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.
