■ 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.

Airfl ow direction adjustment

■ Up/down direction can be adjusted with the AIRFLOW U/D (UP/DOWN) button on the remote control. Every time you press this button the mode changes as follows:

Change on AIRFLOW (UP/DOWN) mode.

(Flap stopped) (Swing)

■ Left/right direction can be adjusted with the AIRFLOW L/R (LEFT/RIGHT) button on the remote control. Every time you press this button the mode changes as follows:

Change on AIRFLOW (LEFT/RIGHT) mode.

(Louver stopped)

NOTE

(Swing)

• The actual position of the fl ap and louver may differ from the display shown.

NOTE FOR HEATING OPERATION

• When operation starts, the fl ap and louver direction is fi xed at the horizontal / center position in order to avoid cold draft, and return to the set the position that was set after the warm air supply is starting.

• The fl ap and louver direction will be controlled to the horizontal/center position when the room temperature reaches the set temperature and compressor stops or when defrosting is in operation.

• The airfl ow direction cannot be set during the period mentioned above. Change the airfl ow direction settings after the warm air is supplied and the fl ap/louver goes to the set position.

MEMORY FLAP (FLAP OR LOUVER STOPPED)

When you press the AIRFLOW (U/D or L/R) button once while the fl ap or louver is operating, it stops swinging at the position. Since this angle is memorized in the microcomputer, the fl ap or louver will automatically be set at this angle when the next operation is started.

WARNING

• Do not expose directly to airfl ow from the air-conditioner for a long time.

CAUTION

• When in COOL or DRY operation, do not operate for a long period with the airfl ow blowing straight down. Otherwise, condensation may appear on the outlet grill and drip down.

• Do not try to adjust the fl aps and louvers by hand, as the control angle may change or the fl ap or louver may not be closed completely.

• Recommended angle of the flap when stopping

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.

NOTE

• The allergen clear fi lter and the photocatalytic washable deodorizing fi lter may be installed on either the right or left side of the air-conditioner.

• Install the allergen clear fi lter with the light orange side front.

5. Install the air fi lters and close the air inlet panel. Page 26

CAUTION

• The heat exchanger may injure your fi ngers.

• Stand fi rmly on a stepladder or other stable object when removing the inlet panel and fi lters.

For replacement the air-cleaning fi lter, contact your dealer.

Proper installation

Suitable installation position

• 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 fl ammable gases.

• Where there is substantial splashing of oil.

• Malfunctioning due to corrosion may occur if the unit is installed in a spa where sulfi de 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 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?

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 29, or if things happen as shown on page 30, 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?

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.

Notice

Air fl ow

Airfl ow is not blown out when starting the HEATING operation.

RUN light blinks slowly

(1.5 sec ON, 0.5 sec OFF)

Airfl ow is not blown out for 5 to 15 min. or blown out not warm wind for a moment at HEATING operation.

RUN light blinks slowly

(1.5 sec ON, 0.5 sec OFF)

Airfl ow is not blown out when starting the DRY operation.

(RUN light is on)

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

KEEP program)

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.

You hear a slight cracking sound.

You hear a hissing or clicking sound.

Whistling noise is heard from the outdoor unit.

Sometimes a “Shooooo” sound might come for a short time from the unit that is turned off.

Others

The unit does not restart immediately after you have stopped it.

(RUN light is on)

Not operating?

This is caused by refrigerating liquid moving within the unit.

This is caused by heat expansion or contraction.

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

The noise means that the revolution speed of the compressor is increasing or decreasing.

This is the sound when operation of another indoor unit is stopped.

Restart is blocked for 3 minutes after you have stopped the operation to protect the unit.

Please wait for three minutes.

The three-minute protection timer in the microcomputer automatically starts it up again.

Some steam escapes during COOL operation.

There is a slight smell.

After a power cut, the unit does not restart even if power has been restored.

Remote control signals are not received.

Moisture may form on the air outlet grills.

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 adhering to the unit.

If the auto restart function is not set, the unit will not restart automatically. 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.

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

Fan will not stop immediately after unit operation was stopped.

RUN light stays on even though operation was stopped.

Indoor fan : Fan will not stop after 2 hours if set to CLEAN operation.

Outdoor fan : Fan will not stop about a 1 minute period in order to protect the unit.

– 29 –

The RUN light illuminates during CLEAN operation.

Run light turns off when CLEAN operation ends.

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.

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.

A switch does not activate properly.

You hear a strange noise 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 sec. ON; 0.5 sec. OFF) and do not work.

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.

ON

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).
