Cleaning the air intake grille
1 Remove the air intake grille.
Hold the two sides of the air intake grille and open
upwards.
Move the centre arm to the left and remove the
grille.
2 Wash it with water using a soft sponge or
towel. (Do not use metallic scrubbing brush
or other hard brushes.)
• Use of such hard objects will cause scratches
on the surface of the grille, and the metal
coating to peel off.
• If very dirty, clean the air intake grille with a
neutral detergent for kitchen use, and rinse it off
with water.
3 Wipe out water from the air intake grille and
dry it.
4 Fit the left and right arms of the air intake
grille to the shafts on the two sides of the air
conditioner and push in completely, and
then push in the centre arm.
5 Check that the centre arm has been
completely inserted and close the air intake
grille.
Push the arrow locations (four) at the bottom of the
air intake grille to check whether the grille is
completely closed.
◆ When not used for a long time
1 Perform the fan operation for a couple of
hours to dry inside.
2 Push button on the remote controller
to stop running, and turn off the circuit
breaker.
3 Clean the air filters and reinstall them.
◆ Before the cooling season
Clean the drain pan
Contact the dealer where you purchased the product.
(Drain does not work if the drain pan or vent is clogged.
In some cases the drain may overflow and wet the wall
or floor. Clean the drain pan before the cooling
season.)
◆ Check periodically
• If the unit is used for a long time, parts may
deteriorate and cause malfunction or bad drainage of
dehumidified water depending on the heat, humidity,
or dust.
• In addition to the usual maintenance, it is
recommended that you have the unit checked and
maintained by the dealer where you purchased it.
NOTE
For environmental conservation, it is strongly
recommended that the indoor and outdoor units of the air
conditioner in use be cleaned and maintained regularly
to ensure efficient operation of the air conditioner.
When the air conditioner is operated for a long time,
periodic maintenance (once a year) is recommended.
Furthermore, regularly check the outdoor unit for rust
and scratches, and remove them or apply rustproof
treatment, if necessary.
As a general rule, when an indoor unit is operated for 8
hours or more daily, clean the indoor unit and outdoor
unit at least once every 3 months. Ask a professional for
this cleaning / maintenance work.
Such maintenance can extend the life of the product
though it involves the owner’s expense.
Failure to clean the indoor and outdoor units regularly
will result in poor performance, freezing, water leakage,
and even compressor failure.
