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.

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.

Airflow direction adjustment

Adjusting airflow direction

Up/down direction can be adjusted with the AIRFLOW (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 (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 FOR HEATING OPERATION

(Swing)

 

When operation starts, the flap and louver direction is fixed 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 flap 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 airflow direction cannot be set during the period mentioned above. Change the airflow direction settings after the warm air is supplied and the flap/louver goes to the set position.

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 the position. 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

• Do not expose directory to airflow from the air-conditioner for a long time.

CAUTION

When in COOL or DRY operation, do not operate for a long period with the airflow 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 be closed completely.

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.

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

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

 

holders in the air-conditioner.

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 flammable 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 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.
