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, 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.
If the air-conditioner does not
operate properly after you have
checked the left points, or if any
doubt still exists after you have
consulted page 21, or if things
happen as shown below, switch
off the power and contact your
dealer.
• 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 switch been turned off?
• 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?
Contact your dealer
■ Turn off the power switch immediately and inform your dealer in any of the following situations:
• The fuse or switch blows continuously.
• The cable becomes extremely hot.
The covering of the cable is cracked.
• The TV, radio or other equipment starts to malfunction.
• A switch does not activate properly.
• A strange noise is heard during operation.
• When abnormalities occur, turn off the power source immediately and turn it on after 3 minutes. Restart the operation with ON/OFF
button of the remote control and the abnormalities still continue.
• The RUN and TIMER lights on the unit display section blink quickly (0.5 seconds ON; 0.5 seconds OFF) or the lights do not work.
