Care And Maintenance
Safety Precautions
•
Contact an authorized service technician for
repair or maintenance. Improper repair and
maintenance may cause water leakage,
electrical shock, or fire, and may void your
warranty.
•
DO NOT
substitute a blown fuse with a
higher or lower amperage rated fuse, as this
may cause circuit damage or an electrical fire.
•
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, fire, and electric shock.
•
Make sure that all wires are connected
properly. Failure to connect wires according
to instructions can result in electrical shock
or fire.
Unit Maintenance
BEFORE CLEANING OR
MAINTENANCE
•
Always turn off your air conditioning system
and disconnect the 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 creates an electrical hazard.
•
DO NOT use water hotter than 40°C (104°F)
to clean the front panel. This can cause the
panel to become deformed or 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 filter prevents dust and other particles from
entering the indoor unit. Dust buildup can reduce
the efficiency of the air conditioner. For optimum
efficiency, clean the air filter every two weeks or
more frequently if you live in a dusty area. Replace
the filter with a new one if it’s heavily clogged and
unable to be cleaned.
WARNING: DO NOT REMOVE OR
CLEAN THE FILTER BY YOURSELF
Removing and cleaning the filter can be
dangerous. Removal and maintenance must be
performed by a certified technician.
NOTE:
In households with animals, you will
have to periodically wipe down the grille to
prevent animal hair blocking airflow.
1. Open the air intake with a screwdriver or
similar tool. Detach the grille from the main
unit by holding the grille at a 45° angle,
lifting it up slightly, and then pulling the grille
forward.
2. Take out the air filter. (applicable to
3.2~10.5KW air conditioners only).
