WARNING
1. Using the specified wires, ensure that the wires
are connected, and fix wires securely so that the
external tension to the wires does not affect the
connecting part of the terminals.
Incomplete connection or fixation may cause a fire,
etc.
2. Be sure to connect the earth wire. (Grounding
work)
Incomplete earthing may lead to electric shock.
Do not connect earth wires to gas pipes, water pipes,
lightning rods or earth wires for telephone wires.
3. The appliance shall be installed in accordance
with national wiring regulations.
Capacity shortages of the power circuit or an
incomplete installation may cause an electric shock
or fire.

line of this air conditioner.
• Incorrect / incomplete wiring may lead to an electrical
fire or smoke.
• Prepare an exclusive power supply for the air
conditioner.
• This product can be connected to the mains power.
Fixed wire connections:
A switch that disconnects all poles and has a contact
separation of at least 3 mm must be incorporated in
the fixed wiring.
• Be sure to use the cord clamps attached to the
product.
• Do not damage or scratch the conductive core or inner
insulator of the power and indoor/outdoor connecting
