■ Refrigerant precautions

• If a refrigerant leak is suspected contact the dealer who supplied
the system, in the case of a recharge of refrigerant ask service
personnel for details of the leak and confirmation of the repairs
completed.
• Generally the refrigerant does not leak, however, if the refrigerant
should leak into a room and a heater or stove burner in the room
is lit, toxic gas may be generated.
• Do not install the system in a location subject to a risk of exposure
to a combustible gas.
If a combustible gas leaks and stays around the unit a fire may
occur.
