■ Care and Cleaning
WARNING
●
For safety, be sure to turn the air conditioner off and
also to disconnect the power before cleaning.
●
Do not pour water on the indoor unit to clean it. This will
damage the internal components and cause an electric
shock hazard.
Air intake and outlet side (Indoor unit)
Clean the air intake and outlet side of the indoor unit with a
vacuum cleaner brush, or wipe them with a clean, soft cloth.
If these parts are stained, use a clean cloth moistened with
water. When cleaning the air outlet side, be careful not to force
the vanes out of place.
CAUTION
● Never use solvents or harsh chemicals when cleaning
the indoor unit. Do not wipe plastic parts using very hot
water.
● Some metal edges and the fins are sharp and may
cause injury if handled improperly; be especially careful
when you clean these parts.
● The internal coil and other components of outdoor
unit must be cleaned regularly. Consult your dealer or
service center.
Air filter
The air filter collects dust and other particles from the air and
should be cleaned at regular intervals as indicated in the
table below or when the filter indication ( ) on the display of
the remote controller (wired type) shows that the filter needs
cleaning. If the filter gets blocked, the efficiency of the air
conditioner drops greatly.
Type U1
Period 6 months
NOT E
The frequency with which the filter should be cleaned depends
on the environment in which the unit is used.
<How to clean the filter>
1. Remove the air filter from the air intake grille.
2. Use a vacuum cleaner to remove light dust. If there is
sticky dust on the filter, wash the filter in lukewarm, soapy
water, rinse it in clean water, and dry it.
<How to remove the filter>
4-Way Cassette Type (U1):
1. Use a screwdriver to remove the bolt screw on each side
for the two latches. (Be sure to reattach the two bolt screws
after cleaning.)
2. Slide the latches of the air intake grille in the direction of
the inside to open the grille.
3. The air intake grille opens downward.
CAUTION
● When cleaning the air filter, never remove the safety
chain. If it is necessary to remove it for servicing and
maintenance inside, be sure to reinstall the safety chain
securely (hook on the grille side) after the work.
● When the filter has been removed, rotating parts (such
as the fan), electrically charged areas, etc. will be
exposed in the unit's opening. Bear in mind the dangers
that these parts and areas pose, and proceed with the
work carefully.
4. Push the side of the air filter marked with the indication
arrow and pull it toward you. The air filter will be
disengaged.
