of infants.
Failure to observe this may result in
the batteries being swallowed or
other accidents.
CAUTION
Only use approved fuses.
Do not handle the switches with wet
hands.
Use of steel or copper wire instead of
an approved fuse is strictly prohibited, as it may cause a breakdown or
fire.
This may cause an electric shock.
Do not place a flammable insecticide or
paint spray near the blower, nor spray it
directly on the system.
You should not expose any combustion appliance directly to the air
stream of the air-conditioner.

Characteristics of HEAT mode operation
Mechanism and capacity of HEAT mode operation
■ Mechanism
• The unit draws heat from the cold outside air, transfers it to indoors and heats the room. As a characteristic of heat pump system, the heating capacity
reduces when the outside air temperature gets colder.
• It may take some time to supply hot air after turning on the air-conditioner.
• If the outside temperature becomes extremely low, it would be better to use an additional source of heating.
Defrosting
If the outside temperature becomes low and humidity is high, the heat exchanger in the outdoor unit may frost over, which prevents efficient heating.
If this happens, the automatic defrost function is activated and during defrosting the heating operation stops for 5 to 15 minutes
during defrosting.
• Both indoor and outdoor fans stop and the RUN light blinks slowly (1.5 sec. ON, 0.5 sec. OFF) during defrosting.
• The outdoor unit may give off some steam during defrosting. This is to help the defrosting process and is not a defect.
• The HEAT operation resumes as soon as defrosting has been completed.

Installing, inspecting, and replacing the air-cleaning filter
1. Open the air inlet panel and remove the air filters.
Page 17
2. Remove the filter holders, with the air-cleaning filter installed in the folders, from the airconditioner.
3. Remove the allergen clear filter (Light orange) from filter holder and inspect the filter. Use
a vacuum cleaner to remove any dust or dirt from the allergen clear filter. Replace the
allergen clear filter if it cannot be cleaned or if it has been for about 1 year.
(The allergen clear 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 (orange) 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 dirt, 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.
Filter holder
(Do not dispose of the filter holders. They are reusable. )

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.
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.

About the Multiple Air-conditioner
Simultaneous Operation
• The air-conditioners cannot be in different operating modes at the same time, such as one unit being in the “Cool” mode and one unit being in
the “Heat” mode.
• When conducting different operations, the air-conditioner that was operated first will be given priority, so the air-conditioner that is operated
after that will conduct air blowing operation.
• When you want to give priority to the air-conditioner that was started later, either stop the air-conditioner that has priority or cause the
operation type of the unit operated first to match that of the unit operated second.
Automatic Operation
• When the remote control operation switch is in the “Auto” mode the air-conditioner automatically selects either “Cool,” “Dry,” or “Heat” when
operation is started depending on the room temperature.
• During simultaneous operation of air-conditioner units, operation modes may be automatically changed in response to the temperatures of the
individual rooms; this will result in the operation of the outdoor unit being stopped. In such a case, COOL or HEAT mode should be used
instead of AUTO. (This is only relevant when more than one air-conditioner unit is being used.)
Refrigerant (oil) recovery operation
• If the all of the indoor units are not operated at the same time for an extended period, the cooling or heating performance may temporarily
decrease. This is in order to control the recovery of the refrigerant (oil) in the stopped indoor unit(s). At this time, the sound of refrigerant
flowing may be heard from the stopped indoor unit(s).
