Operating outside of this range may result in the protection devices being activated, preventing the unit from working.Cooling operation Heating operationOutside temperatureApproximately -15 to 46 °C Approximately -15 to 21 °CInside temperatureApproximately 18 to 32 °C Approximately 15 to 30 °CBelow approximately 80%The long-term use of the unit with a humidity levelInside humidityexceeding 80% may result in condensation formingon the surface of the indoor unit, leading towater drips. 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.Press the FAN SPEED buttonSet the fan speed as preferred. RKW012A401B_EN_001-022 12/08/2010, 13:579–10–

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

• 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.

HEAT (Horizontalblowing)(Slant forwardblowing) COOL, DRY • Recommended angle of the flap whenstopping • 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 tem-

perature 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. (Swing)(Flap stopped)(Louver stopped)(Swing)

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

• Do not leave any obstacles near the outlet and inlet of the outdoor unit. This may cause malfunctioning and increased operating

• 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.

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.

About the Multiple Air-conditioner

Refrigerant (oil) recovery 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.

• 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 tem-

peratures 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.)

Simultaneous 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).
