NOTE
ANNUAL MAINTENANCE
• 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.
• 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 how to
clean the drain pump, contact the dealer.
