MAINTENANCE
NOTE
• 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 dust or oil mist, the pump will be clogged and proper drainage is disabled.
Clean the drain pump periodically. For cleaning the drain pump, contact the dealer.
