Proper installation
Notice
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, fix the unit with the aid of vibration-proof pads between the
unit and the fittings.
• 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.
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
Troubleshooting
Please carry out the following checks before making a service call.
• Do not put any obstruction in front of the indoor unit, preventing proper ventilation and functioning.
• Do not install the unit in any of the following places:
− Where there is a danger of leaking flammable 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 meter away from a TV set or radio.
• Drain the dehumidified liquid from the indoor unit into a spot that drains well.
Inspection and maintenance
The air-conditioner does not work at all.
• Has the power source been turned on?
• Has the timer been set in the “ON” position?
• Is there a power failure or a blown fuse?
Poor cooling or heating
• Have you set the thermostat at a suitable temperature?
• Is the air filter clean? (Not clogged?)
• Have you left any doors or windows open?
• Is there any direct sunlight entering the room?
• Is there a heat source in the room?
• Are there too many people in the room?
Air is not blown out when starting the HEATING operation.
RUN light flashes slowly
(1.5 seconds ON, 0.5 seconds OFF)
Airflow has stopped to prevent blowing out of cold air until the
indoor heat exchanger has warmed up. (2 to 5 minutes)
Air is not blown out for 5 to 15 minutes or cool air is
blown out for a moment at HEATING operation.
RUN light flashes slowly
(1.5 seconds ON, 0.5 seconds OFF)
When outdoor temperature is low and humidity is high, the
unit sometimes performs defrosting automatically. Please
wait. During defrosting, water or steam may release from the
outdoor unit.
Air is not blown out when starting the DRY operation.
(RUN light is on)
The indoor fan may stop to prevent re-evaporation of
dehumidified moisture and to save energy.
Airflow
In the following cases, switch
off the power and contact your
dealer.
• If the air-conditioner does not
operate properly after you
have checked the left points.
• If any doubt still exists after
you have consulted the Notice
(page 31 - 32).
• If things happen as shown on
page 33.
