Cleaning of air outlet louver
The air outlet louver can be removed to clean if necessary.
1
Remove the air outlet louver.
• Holding both ends of the air outlet louver, remove it by sagging the
center downwards.
2
Clean the air outlet louver with water.
• If dirt is heavy, clean the air outlet louver using tepid water with neutral
detergent or just water.
3
Mount the air outlet louver.
• First push in the one side, and insert the opposite side by sagging
the center downwards.
Be careful to insert the louver in the correct direction.
Insert the louver with the printed mark facing upwards, and
the arrow on the louver pointing in the outward direction.
REQUIREMENT
Be sure to clean the heat exchanger with pressurized water.
If a commercially available detergent (strong alkaline or acid) cleaning agent is used, the surface treatment of the
heat exchanger will be marred, which may degrade the self cleaning performance.
For details, contact the dealer.
NOTE

ANNUAL MAINTENANCE

• For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air condi-
tioner 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.
• This product incorporates a drain pump.
If it is used in a place full of duct or oil mist, the pump will be clogged and proper drainage is disabled.
Clean the drain pump periodically. For method to clean the drain pump, contact the dealer.
