<Maintenance/Check list>
Aiming in environmental preservation, it is strictly recommended to clean and maintain the indoor/outdoor units
of the operating air conditioning system regularly to secure effective operation of the air conditioner.
It is also recommended to maintain the units once a year regularly when operating the air conditioner for a long
time.
Check periodically signs of rust or scratches, etc. on coating of the outdoor units.
Repair the defective position or apply the rust resisting paint if necessary.
If an indoor unit operates for approx. 8 hours or more per day, usually it is necessary to clean the indoor/outdoor
units once three months at least.
These cleaning and maintenance should be carried out by a qualified dealer.
Although the customer has to pay the charge for the maintenance, the life of the unit can be prolonged.
Failure to clean the indoor/outdoor units regularly will cause shortage of capacity, freezing, water leakage or
trouble on the compressor.
