Has the unit been installed correctly?
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.
Inspection and maintenance
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.
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.
Installing, inspecting, and replacing the natural enzyme filter and the photocatalytic washable deodorizing filter

Inspecting and replacing the natural enzyme filter and the photocatalytic washable deodorizing filter
1. Open the air inlet grill and remove the air filters.
2. Remove the filter holders, with the natural enzyme filter and the photocatalytic washable
deodorizing filter installed in the holders, from the air conditioner.
3. Remove the natural enzyme filter from the filter holder and inspect the filter. Use a vacuum
cleaner to remove any dust or dirt from the natural enzyme filter. Replace the natural enzyme
filter if it cannot be cleaned or if it has been used for about 1 year.
(The natural enzyme filter should be replaced after about 1 year of use. However, the actual
replacement period may vary depending on the conditions in which the filter is used.)
Remove the photocatalytic washable deodorizing filter from the filter holder and inspect the
filter. Periodically, remove any dust or dirt from the photocatalytic washable deodorizing
filter. If the photocatalytic washable deodorizing filter is particularly dirty, it may be washed
with water. However, the filter is fragile so be sure to wash it installed in the filter holder to
avoid damaging it. After washing the filter, place it in sunlight to dry. Placing the filter in
sunlight revitalizes the deodorizing effect.
(Do not dispose of the filter holders. They are reused.)
4. Install the natural enzyme filter and the photocatalytic washable deodorizing filter in the filter
holders, and then install the filter holders in the air conditioner.
5. Install the air filters and close the air inlet grill.
NOTE
The natural enzyme filter and the photocatalytic washable
deodorizing filter may be installed on either the right or left side of
the air conditioner.
CAUTION
Do not expose natural enzyme filters to direct sunlight for an extended period. The bacteriolytic effect will be lost.
