• Operation outside this humidity or temperature range may cause a safety device to disable the system.

• The displayed items on the LCD will change whenever either one of the buttons is

pressed.

The temperature setting is
not variable.

Press to raise the temperature and press to lower the
temperature.

• For cooling: 26-28˚C

• For heating: 20-24˚C

• Be careful not to cool (heat) the room too much.

Keeping the temperature setting at a moderate level helps save energy

• Cover windows with a blind or a curtain.

Blocking sunlight and air from outdoors increases the cooling (heating) effect.

• Clogged air filters cause inefficient operation and waste energy. Clean them once in about every 2 weeks.

• The outdoor unit consumes some power to have its electric components work even while it is not operating.

Connecting outdoor unit RXG25/35: 1-15W
Other outdoor units: 15-20W

The outdoor unit consumes 40 to 55W of power at the time of compressor preheating.

• If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker off.

• Use the air conditioner in the following conditions.

• A safety device may work to stop the operation.

(In multi system, it may work to stop the operation of the
outdoor unit only.)

• Condensation may occur on the indoor unit and drip.

Outdoor temperature : <2/3/4/5MXS> –10-46˚C

<RXG> –10-46˚C

Indoor temperature : 18-32˚C
Indoor humidity : 80% max.

Outdoor temperature : <2MXS> –10-24˚C
