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 grounding may lead to electric
shock.
Do not connect ground wires to gas pipes, water
pipes, lightning rods or ground 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.
CAUTION
• Wrong wiring may cause a burn-out of some electrical
parts.
• 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 inter-connecting wires
when peeling them.
• Use the power and inter-connecting wires with
specified thicknesses, specified types 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 system
interconnection wires with a 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.)
Ensure all wires are secured using the cord clamps on
the pipe valve fixing plate located inside the unit
