• Before doing repair work, please read the " SAFETY PRECAUTIONS" carefully and fully understand them. • The precautionary items here are divided into " W arning" and " Caution" items.
W arning If refrigerant gas blows off during the work, do not touch the refrigerant gas as it may cause frostbite. If refrigerant gas leaks during the work, ventilate the room. If refrigerant gas catches fire, harmful gas may be generated. Do not mix any gas other than the specified refrigerant gas in the refrigerating cycle.
