Having trouble?
Noise is louder than specifi cations.
Nothing appears in the wireless remote controller display, the display
is faint, or signals are not received by the indoor unit unless the remote
controller is close.
The operation lamp near the receiver for the wireless remote controller
on the indoor unit is fl ashing.
Warm air blows from the indoor unit intermittently when heating mode is
off or during fan mode.
Range of application
The range of working temperatures for both the indoor and outdoor units of the series Y, R2, Multi-S is as below.
Caution:
The use of your air conditioner outside the range of working temperature and humidity can result in serious failure.
Mode
Cooling 15 °C - 24 °C WB, 59 °F - 75 °F WB
Heating
Note: As an applicable humidity standard for both indoors and outdoors, we recommend use within a range of 30 - 80% relative humidity.
Warning:
If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since there may be a refrigerant
leak. Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors and
comes into contact with the fi re of a fan heater, space heater, stove, etc., harmful substances will be generated.

small rooms, etc., stop the operation of the indoor unit temporarily.
