Safety Precautions
Keep this manual where the operator can easily fi nd them.•
Read the precautions in this manual carefully before operating the unit.•
The precautions described herein are classifi ed as WARNING and CAUTION. They both contain important information •
regarding safety. Be sure to observe all precautions without fail.
WARNING
CAUTION
Failure to follow these instructions properly may result in
personal injury or loss of life.
Failure to observe these instructions properly may result in
property damage or personal injury, which may be serious
depending on the circumstances.
Never attempt.
Never wet the air conditioner nor the remote controller with
water.
Be sure to follow the instructions.
Never touch the air conditioner nor the remote controller with

Beware of fi re in case of refrigerant leakage. If the air conditioner is not operating correctly, i.e. not generating cool or •
warm air, refrigerant leakage could be the cause. Consult your dealer for assistance. The refrigerant within the air
conditioner is safe and normally does not leak.
However, in the event of a leakage, contact with a naked burner, heater or cooker may result in generation of noxious
gas. Do not longer use the air conditioner until a qualifi ed service person confi rms that the leakage has been
repaired.
Do not attempt to install or repair the air conditioner yourself. Improper workmanship may result in water leakage, •
electric shocks or fi re hazards. Please contact your local dealer or qualifi ed personnel for installation and
maintenance work.
When the air conditioner is malfunctioning (giving off a burning odour, etc.) turn off power to the unit and contact your •
local dealer. Continued operation under such circumstances may result in a failure, electric shocks or fi re hazards.
Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks or fi re.
•
Be sure to earth the unit. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect •
earthing may result in electric shocks.
CAUTION
Do not use the air conditioner for purposes other than those for which it is intended. Do not use the air conditioner for •
cooling precision instruments, food, plants, animals or works of art as this may adversely affect the performance,
quality and/or longevity of the object concerned.

NOTE
MODE Notes on each operation mode
HEAT
Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in •
lower outdoor temperatures. If the heating effect is insuffi cient, it is recommended to use another heating appliance in
combination with the air conditioner.
The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation, •
it takes some time before the room gets warmer.
In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches •
into defrosting operation to take away the frost.
During defrosting operation, hot air does not fl ow out of indoor unit.•
COOL
This air conditioner cools the room by blowing the hot air in the room outside, so if the outside temperature is high, the •
performance of the air conditioner drops.
DRY
The computer chip works to rid the room of humidity while maintaining the temperature as much as possible. It automatically •
controls temperature and airfl ow rate, so manual adjustment of these functions is unavailable.
AUTO
In AUTO operation, the system selects a temperature setting and an appropriate operation mode (COOL or HEAT) based on •
the room temperature at the start of the operation.
The system automatically reselects setting at a regular interval to bring the room temperature to user-setting level.•
FAN This mode is valid for fan only.•

For cooling: 26-28°C•
For heating: 20-24°C•
Tips for saving energy
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 fi lters cause ineffi cient operation and waste energy. Clean them once in about every 2 weeks.•
Notes on the operating conditions
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.•
