If refrigerant gas has leaked during the installation work, ventilate the room immediately.

After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a fan heater, cooking stove or heating
unit, noxious gas may be generated.
