WARNING
1. Using the specified wires, ensure to connect the
wires, and fix wires securely so that the external
tension to the wires do not affect the connecting
part of the terminals.
Incomplete connection or fixation may cause a fire,
etc.
2. Be sure to connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water
pipes, lightning rods or ground wires for telephone
wires.
3. Appliance shall be installed in accordance with
national wiring regulations.
Capacity shortage of power circuit or incomplete
installation may cause an electric shock or a fire.
CAUTION
• Wrong wiring may cause a burn-out to some electrical
parts.
• Be sure to use the cord clamps attached to the
product.
• Do not damage or scratch the conductive core and
inner insulator of power and inter-connecting wires
when peeling them.
• Use the power and Inter-connecting wires with
specified thickness, specified type and protective
devices required.
• Remove the panel, and you can see electric parts on
the front side.
• A metal pipe can be installed through the hole for
wiring. If the hole size does not fit the wiring pipe to
be used, drill the hole again to an appropriate size.
• Be sure to clamp the power wires and hydro/outdoor
connecting wires with banding band along the
connecting pipe so that the wires do not touch the
compressor or discharge pipe. (The compressor and
the discharge pipe become hot.)
