ELECTRIC WORK
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
• If incorrect/incomplete wiring is carried out, it
will cause an electrical fire or smoke.
• Be sure to install an earth leakage breaker that
is not tripped by shock waves.
If an earth leakage breaker is not installed, an
electric shock may be caused.
• 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 cord and Inter-connecting wire
of specified thickness, type, and protective
devices required.
• Never connect 220–240V power to the terminal
blocks (
,
,
,
, etc.) for control
wiring.
(Otherwise, the system will fail.)
REQUIREMENT
• For power supply wiring, strictly conform to the
Local Regulation in each country.
• For wiring of power supply of the outdoor units,
follow the Installation Manual of each outdoor
unit.
• Perform the electric wiring so that it does not
come to contact with the high-temperature part
of the pipe.
The coating may melt resulting in an accident.
• After connecting wires to the terminal blocks,
provide a trap and fix wires with the cord clamp.
• Run the refrigerant piping line and control wiring
line in the same line.
• Do not turn on the power of the indoor unit until
vacuuming of the refrigerant pipes completes.
