4. Troubleshooting

Before you ask for repair service, check the following points:
State of Machine
It does not run.
Air flows out but it does not cool enough or
heat enough.
Cool air or warm air does not come out.
The sound of the exhaust and rotation of the
motor can still be heard after stop of running.
The following symptoms are not air conditioner failures:
• The air blown out from the air conditioner can sometimes give off odors. This is due to cigarette smoke contained in the air of the room, the smell of
cosmetics, the walls, furniture, etc., absorbed in the air conditioner.
• A hissing noise can be heard immediately after the air conditioner is started or stopped. This is the sound of the refrigerant flowing inside the air
conditioner. The problem is insignificant.
• The air conditioner sometimes snaps or clicks at the beginning or end of cooling/heating operation. This is the sound of friction on the front panel and
other sections due to inflation and contraction caused by temperature change. The problem is insignificant.
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 Indoor unit
Cooling 15 °C - 24 °C WB
Heating 15 °C - 27 °C DB
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.
