Owner’s Manual

Be careful with noise or vibrations

•Do not install the air conditioner in a place where noise by outdoor unit or hot air from its air outlet annoys your neighbors.

•Install the air conditioner on a solid and stable foundation so that it prevents transmission of resonating, operation noise and vibration.

•If one indoor unit is operating, some sound may be audible from other indoor units that are not operating.

WARNING

Re-Installation

Ask the dealer or an installation professional to re-install the air conditioner to a new place or move it to another place and to observe the following items.

If the air conditioner is inappropriately installed by yourself, it may cause electric shock or fire.

Maintenance

•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.

CAUTION

Be sure to clean the heat exchanger with pressurized water.

If an commercially detergent (strong alkaline or acid cleaning agent) is used, the surface treatment of the heat exchanger will be marred, which may degrade the self cleaning performance.

For details, contact the dealer.
