▼ Periodic 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.
1, 3
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.
