Has the unit been installed correctly?
Suitable installation position
• Is there any obstruction in front of the indoor unit, preventing proper ventilation and functioning?
• Don't install the unit in any of the following places:
• Where there is a danger of leaking inflammable gases.
• Where there is substantial splashing of oil.
• Malfunctioning due to corrosion may occur if the unit is installed in a spa where sulfide gases are generated, or in a seaside resort exposed to
sea breezes. Contact your dealer.
• The air-conditioner and remote control must be at least 1 metre away from a TV set or radio.
• Drain the dehumidified liquid from the indoor unit into a spot that drains well.
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 there is any likelihood that vibration may be transmitted through the house, fix the unit with the aid of vibration-proof pads
between the unit and the fittings.
•
Select a place where cold or hot air and 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.
Dependent upon service conditions and operating environment, the inside of the air-conditioner may become dirty after a number of seasons'
service (3 to 5 years). This will reduce performance. In addition to normal cleaning, we would recommend inspection and maintenance. (The air-
conditioner has 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.
