• Install the air conditioner according to this Installation Manual.
• Have all electric work done by a licensed electrician according to local
regulations.
• Do not use intermediate connection of electric wires.
• If the air conditioner is installed in a small room, measures must be taken to
prevent the refrigerant concentration from exceeding the safety limit even if
the refrigerant should leak.
Caution:
• Do not use the existing refrigerant piping, when use R410A refrigerant.
• Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil
to coat flares and flange connections, when use R410A refrigerant.

• When installing or relocating, or servicing the air conditioner, use only the
specified refrigerant (R410A) to charge the refrigerant lines. Do not mix it
with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other
hazards.
T he use of any refrigerant other than that specified for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to securing product safety.
