Safety precautions

• Before starting to use the system, please read these “Safety precautions” carefully to ensure proper operation of the system.

• The safety precautions are classified as “

DANGER” and “ CAUTION”. Precautions as shown in the column “ DANGER” indicate that improper handling could have dramatic consequences like death, serious injury, etc. Nevertheless, even precautions as shown in the column

“ CAUTION” might pose a serious problem, depending on the circumstances. Please observe these precautions with great care, since they are essential to your safety.

• Symbols which appear frequently in the text have the following meaning:

Strictly prohibited

Observe instructions with great care

Provide positive earthing

• When you have read the instruction manual, please keep it near at hand for consultation. If someone else takes over as operator, make certain that the manual is also passed on to the new operator.

INSTALLATION PRECAUTIONS

DANGER

The system is meant for domestic, residential etc. use.

The system must be installed by your dealer or a qualified professional.

If used in inferior environments, such as an engineering workplace, the equipment may function poorly.

It is not advisable to install the system yourself, as faulty handling may cause leakage of water, electric shock or fire.

CAUTION

Do not install near places where inflammable gas may leak.

Depending on the place of installation, a circuit breaker may be necessary.

LPG

Gas leaks may cause fire.

Make sure that you drain the hose properly, so that all the water has dripped out.

If you don’t fit a circuit breaker, you may cause an electric shock.

Make sure that the system has been properly earthed.

Negligence may cause flooding in the room resulting in wet furniture.

Earth cables should never be connected to a gas pipe, municipal water pipe, lightning conductor or telephone earth cable. Incorrect installation of the earth cable may produce an electric shock.

OPERATION PRECAUTIONS

Do not expose yourself to the cooling air for prolonged periods.

DANGER

Do not insert anything into the air inlet.

Air-conditioner operating conditions

■ 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

Outside temperature Approximately -15 to 46 °C

Heating operation

Approximately -15 to 21 °C

Inside temperature Approximately 18 to 32 °C

Inside humidity

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 drips.

Approximately 15 to 30 °C

Characteristics of HEAT mode operation

Mechanism and capacity of HEAT mode operation

Mechanism

• The unit draws in heat from the cold outside air, transfers it indoors and heats the room. The heating capacity of the heat pump mechanism decreases when the outside air temperature gets colder.

• The hot air circulation system takes a while before warming up the room temperature.

• 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 defroster is activated and during defrosting the heating operation stops for 5 to 10 minutes.

• Both indoor and outdoor fans stop and the RUN light (green) 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.

Change to AIRFLOW (LEFT/RIGHT) mode.

(LEFT/RIGHT) button on the remote control. Each time when you press this

(Louver stopped)

(Swing)

NOTE

• When heating operation starts, the cold air outlet is blocked, so the flap and louver move to the horizontal / center position, and resume the position that was set after the warm air output begins.

• When the compressor stops because the room temperature is higher than the temperature setting and it is in DEFROSTING operation, the flap and louvers will be in the horizontal / center position.

• The air flow direction cannot be set in the instances above. Change the air flow direction settings after the warm air starts flowing and it moves to the airflow direction that had been set.

Multi-directional Air Flow (up/down air scroll and left/right air scroll)

■ Activating both up/down air swing and left/right air swing at the same time results in a multi-directional air flow.

MEMORY FLAP (FLAP OR LOUVER STOPPED)

When you press the AIRFLOW (UP/DOWN or LEFT/RIGHT) button once while the flap or louver is operating, it stops swinging at an angle.Since this angle is memorized in the microcomputer, the flap or louver will automatically be set at this angle when the next operation is started.

DANGER

• Avoid constant airflow to the body for hours on end.

CAUTION

• When in COOL or DRY operation, do not operate for hours on end with the air flow blowing straight down. Otherwise, condensation may appear on the outlet grill and drip down.

• Do not try to adjust the flaps and louvers by hand, as the control angle may change or the flap or louver may not close properly.

Installing, inspecting, and replacing the allergen clear filter and the photocatalytic washable deodorizing filter

1. Open the air inlet panel and remove the air filters.

2. Remove the filter holders, with the allergen clear filter and the photocatalytic washable deodorizing filter installed in the folders, from the air-conditioner.

3. Remove the allergen clear filter 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 from the filter holder and inspect the filter. Periodically, remove any dust or dirt or from he 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.

(Do not dispose of the filter holders. They are reused. )

4. Install the allergen clear filter and the photocatalytic washable deodorizing filter in the filter holders, and then install the filter holders in the air-conditioner.

Has the unit been installed correctly?

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.

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 airconditioner 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.

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?

Has the timer been set in the

“ON” position?

Is there a power failure or a blown fuse?

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

20, or if things happen as shown on page 21, switch off the power and contact your dealer.

Have you set the thermostat at a suitable temperature?

suitable temperature

Poor cooling or heating

Is the air filter clean? (Not clogged?)

Did you leave any doors or windows open?

Is there any direct sunlight entering the room?

Poor cooling

Is there a heat source in the room?

Are there too many people in the room?

(RUN light is on)

Some steam escapes during COOL operation.

There is a slight smell.

You hear a slight gurgling sound.

Air flow has stopped to prevent blowing out of cold air until the indoor heat exchanger has warmed up. (2 to 5 min.) (HOT KEEP)

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 dehumified moisture and to save energy.

This may occur if the room's temperature and humidity are very high.

It disappears as soon as the temperature and humidity decrease.

Air blown out during operation may smell. This is caused by tobacco or cosmetics sticking to the unit.

This is caused by refrigerating liquid moving within the unit.

You hear a slight cracking sound.

You hear a hissing or clicking sound.

After a power cut, you cannot re-start, even if power has been restored, unless you have the power blackout auto restart function.

Remote control signals are not received.

This is caused by heat expansion or contraction.

This is caused by the operation of the refrigerant control valves or electric components.

The memory circuit of the microcomputer has been wiped out. Use the remote control to start the operation again.

Remote control signals may not be received if the signal receiver on the air-conditioner is exposed to direct sunlight or other bright light.

If so, cut out the sunlight or reduce the other light.

Moisture may form on the air outlet grills.

Whistling noise is heard from the outdoor unit.

If the unit is operated for a long time in high humidity, moisture may form on the air outlet grills and start dripping.

The noise means that the revolution speed is picking up on the compressor.
