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.
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 fire of a fan heater, space heater, stove, etc., harmful substances will be generated.
