Air-conditioner operable temperature setting

■ Use within the following operational range. Operating outside of this range may result in the protection devices being activated, preventing the unit from working.

Cooling operation Heating operation

Outside temperature

Inside temperature

Inside humidity

Approximately -15 to 46 °C Approximately -15 to 24 °C

Approximately 18 to 32 °C Approximately 10 to 30 °C

Below approximately 80% The long-term use of the unit with a humidity level exceeding 80% may result in condensation forming on the surface of the indoor unit, leading to water drops.

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 efﬁ cient 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 ﬁ lter

1. Open the air inlet panel and remove the air ﬁ lters. Page 26

2. Remove the ﬁ lter holders, with the air-cleaning ﬁ lter installed in the folders, from the air-conditioner.

3. Remove the allergen clear ﬁ lter (Light orange) from ﬁ lter holder and inspect the ﬁ lter. Use a vacuum cleaner to remove any dust or dirt from the allergen clear ﬁ lter. Replace the allergen clear ﬁ lter if it cannot be cleaned or if it has been for about 1 year. (The allergen clear ﬁ lter should be replaced after about 1 year of use. However, the actual replacement period may vary depending on the conditions in which the ﬁ lter is used.)

Remove the photocatalytic washable deodorizing ﬁ lter (orange) from the ﬁ lter holder and inspect the ﬁ lter. Periodically, remove any dust or dirt from the photocatalytic washable deodorizing ﬁ lter. If the photocatalytic washable deodorizing ﬁ lter is particularly dirty, it may be washed with water. However, the ﬁ lter is fragile so be sure to wash it installed in the ﬁ lter holder to avoid damaging it. After washing the ﬁ lter, place it in sunlight to dry. Placing the ﬁ lter in sunlight revitalizes the deodorizing effect.

(Do not dispose of the ﬁ lter holders. They are reusable. )

4. Install the air-cleaning ﬁ lter in the ﬁ lter holders, and then install the ﬁ lter

holders in the air-conditioner.

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 dehumidiﬁ ed 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 vibration is transmitted through the house, ﬁ x the unit with the aid of vibration-proof pads between the unit and the ﬁ ttings.

• 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.

Troubleshooting

Please carry out the following checks before making a service call.

The air-conditioner does not work at all.

Has the power switch been turned off?

Have you set the thermostat at a suitable temperature?

suitable

temperature

Is there any direct sunlight entering the room?

Has the timer been set in the “ON” position?

Poor cooling or heating

Is the air filter clean? (Not clogged?)

Poor cooling

Is there a heat source in the room?

Is there a power failure or a blown fuse?

Did you leave any doors or windows open?

Are there too many people in the room?

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 29, or if things happen as shown on page 30, switch off the power and contact your dealer.

An alternative refrigerant (R410A) is used in this air-conditioner. When asking your dealer for service or inspection and maintenance, explain the dealer about it.

When outdoor temperature is low and humidity is high, the unit sometimes performs defrosting automatically. Please wait. During defrosting, water or steam may escape from the outdoor unit.

The indoor fan may stop to prevent re-evaporation of dehumiﬁ ed moisture and to save energy.

Noise

You hear a slight gurgling sound. This is caused by refrigerating liquid moving within the unit.

You hear a slight cracking sound. This is caused by heat expansion or contraction.

You hear a hissing or clicking sound. This is caused by the operation of the refrigerant control

■ Turn off the power switch immediately and inform your dealer in any of the following situations:

The fuse or switch blows continuously.

Fuse often blows.

The cable becomes extremely hot. The covering of the cable is cracked.

CAUTION

If the power cord becomes damaged, ask your dealer or a qualiﬁ ed engineer to install the replacement to avoid accidents.

The TV, radio or other equipment starts to malfunction.

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.

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 ﬁ rst 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 ﬁ rst to match that of the unit operated second.

• When other indoor units are operating in different modes, the RUN light illuminates.

0.5 sec.

OFF

0.5 sec.

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 ﬂ owing may be heard from the stopped indoor unit(s).
