Check periodically
• If the unit is used for a long time, parts may deteriorate and cause malfunction or bad drainage of dehumidifi ed
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 effi cient 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, water leakage, and even
compressor failure.
