Safety Precautions
• Contact an authorized service technician for
repair or maintenance. Improper repair and
maintenance may cause water leakage,
electrical shock, or re, and may void your
warranty.
• DO NOT
substitute a blown fuse with a fuse
that has a higher or lower amperage rating,
as this may damage the circuit or cause an
electrical re.
• Make sure the drain hose is set up according
to the instructions. Failure to do so could
cause leakage and result in personal
property damage, re and electric shock.
• Make sure that all wires are connected
properly. Failure to connect wires according
to instructions can result i n electrical shock
or re.
Unit Maintenance
BEFORE CLEANING OR
MAINTENANCE
• Always turn off your air conditioning system
and disconnect its power supply before
cleaning or maintenance.
•
DO NOT
use chemicals or chemically treated
cloths to clean the unit.
•
DO NOT
use benzene, paint thinner,
polishing powder or other solvents to clean
the unit. They can cause the plastic surface
to crack or deform.
•
DO NOT
wash the unit under running
water. Doing so causes electrical danger.
•
DO NOT
use water hotter than 40°C (104°F)
to clean the front panel. This can cause the
panel to deform or become discolored.
• Clean the unit using a damp, lint-free cloth
and neutral detergent. Dry the unit with a
dry, lint-free cloth.
How To Clean The Air Filter
The lter prevents dust and other particles from
entering the indoor unit. Dust buildup can reduce
the efciency of the air conditioner. For optimum
efciency, clean the air lter every two weeks or
more frequently if you live in a dusty area. Replace
the lter with a new one if it’s heavily clogged and
cannot be cleaned.
WARNING: DO NOT REMOVE OR
CLEAN THE FILTER BY YOURSELF
Removing and cleaning the lter can be
dangerous. Removal and maintenance must be
performed by a certied technician.
NOTE: In households with animals, you will
have toperiodically wipe down the grille to
prevent animal hair blocking airow.
Care And Maintenance 4
Carry the lter and pull
it out sidewards.
Cleaning the dust lters back of the unit:
Hold the handler of
the lter.
3. Remove the air lter.
4. Clean the air lter by vacuuming the surface
or washing it in warm water with mild
detergent.
A. If using a vacuum cleaner, the inlet side
should face the vacuum.

Repairing Refrigerant Leaks
WARNING
• If the refrigerant leaks, turn off the air
conditioner and any combustible heating
devices, ventilate the room and call your
dealer immediately. Refrigerant is both toxic
and ammable.
DO NOT
use the air
conditioner until the leak is repaired.
• When the air conditioner is installed in a
small room, measures must be taken to
prevent the refrigerant concentration from
exceeding the safety limit in the event of
refrigerant leakage. Concentrated
refrigerant causes a severe health and safety
threat.
Refrigerant Leak Detection System (some
models)
• In the event of a refrigerant leak, the LCD
screen will display “EC” and the LED
indicator light will ash.
Preparation For Periods Of Non-Use
Maintenance after Extended Non-Use
1. Remove any obstacles blocking the vents of
both the indoor and outdoor units.
2. Clean the air lter and the front grille of the
indoor unit. Reinstall the clean, dry air lter in
its original position.
3. Turn on the main power switch at least 12
hours prior to operating the unit.
Storing the Unit While Not In Use
1. Run the appliance on FAN mode for 12 hours
in a warm room to dry it and prevent mold.
2. Turn off the appliance and unplug it.
3. Clean the air lter according to the
instructions in the previous section. Reinstall
the clean, dry lter before storing.
4. Remove the batteries from the remote control.
5. Rinse the lter with clean water and allow
it to air-dry.
DO NOT
let the lter dry in
direct sunlight.
6. Reinstall the lter.
B. If using water, the inlet side should face
down and away from the water stream.
