4. CARE AND MAINTENANCE
Cleaning Your Air Filters
A dirty air filter will cause a reduction of airflow. Reduction of airflow causes overloading
and consumes more electricity. Therefore, regular cleaning is necessary for efficient and
trouble-free operation.
Remove the air filter from the return air
grille.
Remove dust from the air filter by using
vacuum cleaner or, if it is very dirty,
wash it with soap and wipe it dry
before reinstalling it.
Remove the return air grille.
For plastic return grilles, no screw
is used. Start removing the return grille
by pulling the bottommost part of the
grille.
WARNING: Ensure that the power supply is switched off
before commencing maintenance work.

Cleaning The Unit
Clean the air conditioner with a
damp cloth and wipe it dry.
Do not use water above 40
o
C for
cleaning, as this will cause discolo-
ration and deformation.
Remove dust from the louver area
with your vacuum cleaner’s thin
nozzle.
Do not splash directly with water to
the body of the unit, as this may
cause a short circuit.
Do not use thinner, benzene,
abrasive powder, nor hot water to
clean the unit.
5. CLEANING THE UNIT
Not to be Operated for a Long Period of Time
When the air conditioner is not going to be used for a long period
of time, switch off the power from the circuit breaker.
Before Putting The System Back To Operation
Turn on the main power to the system at the outdoor unit.
Run the unit in fan mode for a while to clear the air flow before you operate
it in another mode.
Tips on Using the Air Conditioner
After a Power Failure
Auto-restart function and non-volatile memory will automatically turn ON the unit
and return it to its previous setting.
Clean the filter every other week for higher efficiency.
Use curtains or blinds to prevent heat gain from the sunlight to the room.
Doing so will help reduce electric consumption.
Close all windows and doors when operating the unit so that there is no
leakage of conditioned air outside the room.
Do not locate a heater or any other heat source near the unit. The heat
may deform plastic parts.
THE FOLLOWING ARE JUST NORMAL CONDITIONS FOR THE UNIT:
The unit does not operate upon
restart.
If you restart the unit within 3 minutes after turning it
OFF, or change the mode during operation, a
protective device will work to shut OFF the
valve for 3 minutes. Cooling will resume
automatically after the 3-minute delay.
Low Noise.
A soft, swishing noise can be heard during operation or
immediately after the unit is turned OFF. This is the
sound of the circulating refrigerant.
Condensate water or water droplets
present on the air outlet.
In COOL mode, condensate water can sometimes be
seen forming on the air outlet due to the
differences in temperature between the room air
and the outlet air.
