CARE AND MAINTENANCE

CLEANING YOUR INDOOR UNIT
CAUTION
BEFORE CLEANING OR MAINTAINING THE UNIT
Always turn the unit off and disconnect its power supply before
cleaning or maintaining the unit.
When removing filter, do not touch metal parts in the unit. The
sharp metal edges can cut.
DO NOT use water to clean the inside of the indoor unit. This can
destroy insulation and cause an electrical shock.
DO NOT expose the filter to direct sunlight when drying. This can
shrink the filter.
CAUTION
Any maintenance and cleaning of the outdoor unit should be
performed by an authorized dealer or a licensed service provider.
Any unit repairs should be performed by an authorized dealer or a
licensed service provider.
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 rating
fuse, as this may cause circuit damage or an electrical fire.
Ensure the drain hose is set up according to the instructions. Failure to do
so may cause leakage and result in personal property damage, fire and
electric shock.
Ensure all wires are connected properly. Failure to connect wires according to
instructions can result in electrical shock or fire.
CAUTION
MAINTAINING THE UNIT
Only use a soft, dry cloth to wipe the unit clean. If the unit is
especially dirty, you can use a cloth soaked in warm water to wipe
it clean.
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 use water hotter than 104°F (40°C) to clean the front
panel. This can cause the panel to deform or become discolored.
DO NOT wash the unit under running water. Doing so creates an
electrical hazard. Clean the unit using a damp, lint-free cloth and
neutral detergent. Dry the unit with a dry, lint-free cloth.
