Proper installation
Pay attention to operating noises!
• When you install the unit, take care to choose a place that can comfortably stand the weight of the unit and does not increase the
operating noise or vibration. If vibration is transmitted through the house, fi x the unit with the aid of vibration-proof pads between the
unit and the fi ttings.
• Select a place where cold or hot air, operation noises from the indoor and outdoor units do not cause any inconvenience to your
neighbours.
• Do not leave any obstacles near the outlet and inlet of the outdoor unit. This may cause malfunctioning and increased operating noise.
• If you hear an irregular noise during operation, contact your dealer.
Inspection and maintenance
Depending on operating environment, the inside of the air-conditioner may become dirty after a few year operations. This will reduce
performance. In addition to normal cleaning, we would recommend inspection and maintenance. (This may lead the air-conditioner to
having a longer life without any trouble.)
• Contact your dealer, or any distributor, for inspection and maintenance. (There will be a charge for this service).
• We would recommend inspection and maintenance to be carried out during the off-season.
• If the supply cord of this appliance is damaged, it must only be replaced by a repair shop appointed by the manufacturer, because
special purpose tools are required.
Suitable installation position
The air-conditioner does not work at all.
Has the timer been set in the
“ON” position?
Has the power switch been
turned off?
Is there a power failure or a
blown fuse?
