Maintenance

WARNING
Cleaning the air fi lter and other parts of the air fi lter involves dangerous work in high places, so be sure
to have a qualifi ed installer or qualifi ed service person to do it.
Do not attempt it by yourself.
CAUTION
Do not push buttons with wet hands.
Doing so may result in electric shock.
Cleaning the air fi lters
• When the fi lter indicator is displayed on the remote controller, clean the air fi lters.
(Only for RBC-AMTU*** and RBC-AMSU*** remote controllers.)
• Clogged fi lters may lower the cooling and heating performance.
When the unit will not be used for a long time
1. Perform the fan operation for a couple of hours to dry inside.
2. Stop the air conditioner with the remote controller and turn off the circuit breaker.
3. Clean the air fi lters and reinstall them.
Before the cooling season
Clean the drain pan
• Contact the dealer where you purchased the product.
(Drain does not work if the drain pan or vent is clogged. In some cases the drain may overfl ow and wet the wall
or fl oor. Be sure to clean the drain pan before the cooling season.)
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, freezing, water leakage,
and even compressor failure.
