• Do not place any combustion appliance in a place where it is directly
exposed to the wind of Air to Air Heat Exchange with DX Coil unit,
otherwise it may cause imperfect combustion.
• If refrigerant gas has leaked during the installation work, ventilate the
room immediately. If the leaked refrigerant gas comes in contact with
fire, noxious gas may be generated.
• After the installation or servicing work, check the refrigerant gas does
not leak.
• If refrigerant gas leaks in the room, poisonous gas generates when
gas touches to fire such as fan heater, stove or cooking stove though
the refrigerant gas itself is innocuous.
• Inspect the Air to Air Heat Exchanger with DX Coil Unit for any falling
hazard of the unit before maintenance or repair.
• Do not modify the products. Do not also disassemble or modify the
parts. It may cause a fire, electric or injury.
