Care and Maintenance
Care and Maintenance
CAUTION: Before performing any maintenance, turn off the main power to the system.
You can do some of the periodic maintenance for your unit yourself; this includes cleaning air filters, cleaning unit
cabinet, clearing the condenser coil, and conducting a general unit inspection on a regular basis.
WARNING: Before removing access panels to service unit, disconnect power supply.
Failure to disconnect power before attempting any servicing can result in severe injury
or death.
This product has anti-bacteria washable filters. It is very important to keep air filters clean in the central duct
system. Be sure to inspect them at least once each month when the system is in constant operation. (In new
buildings, check the filters every week for the first 4 weeks.)
Washable type filters can be cleaned by washing with a mild detergent and water. Ensure that the filters are
thoroughly dried before reinstalled them in the unit (or duct system).
Condenser coil
Unfiltered air circulates through the unit's condenser coil and can cause the coil's surface to become clogged with
dust, dirt, etc.. To clean the coil, vertically (i.e., along the fins) stroke the coil surface with a soft bristled brush.
Keep all vegetation away from the condenser coil area.
Maintenance Performed by serviceman-Cooling Season
To keep your unit operating safely and efficiently, the manufacturer recommends that a qualified serviceman
check the entire system at least once each year, or more frequently if conditions warrant. Your serviceman may
examine these areas of your unit:
1. Filters (for cleaning)
2. Motors and drive system components
3. Condenser coils (for cleaning)
4. Safety Controls (for mechanical cleaning)
5. Electrical components and wiring (for possible replacement or connection tightness)
6. Condensate drain (for cleaning)
7. Inspect the unit duct connections to ensure they are physically sound and sealed to the unit casing.
8. Inspect the unit mounting support to see that it is sound.
9. Inspect the unit to ensure there is no obvious deterioration.
Maintenance Performed by serviceman-Heating Season
Complete the unit inspections and service routines described below at the beginning of each heating season.
• Inspect the controller panel wiring to verify that all electrical connections are tight and that wire insulation is

Operation Tips
Do not overcool the room.
This is not good for your health and
wastes electricity.
Keep blinds or curtains
Do not let direct sunshine enter the
room when the air conditioner is in
Clean the air filter regularly.
Blockages in the air filter reduce the
airflow and lower cooling and
dehumidifying effects.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and windows
as much as possible to keep the
cool air in the room.
Ventilate the room
Since windows are kept closed, it is
a good idea to open them and
ventilate the room now and then.
Before removing access panels to
draw out air filters, disconnect
power supply.
Since the fan rotates at high speed, it
may cause a serious injury
Clean at least once every
month using a vacuum
cleaner or washing with a
neutral detergent in
lukewarm water.
After washing with water,
dry it well in the shade.
• Do not expose the air filter to
direct sunlight or heat from a
