outdoor unit, indoor units and the remote controller. For details
on hooking up the remote controller, refer to the "Installation
manual of the remote controller".
All wiring must be performed by an authorized electrician.
Attach the earth leakage circuit breaker and fuse to the power
supply line.
A main switch or other means for disconnection, having a

wiring in accordance with relevant local and national legislation.
Note that the operation will restart automatically if the main
power supply is turned off and then turned back on again.
Refer to the installation manual delivered with the outdoor unit
for the size of power supply electric wire connected to the
outdoor unit, the capacity of the earth leakage breaker and fuse
and for wiring instructions.
Be sure to ground the air conditioner.
Do not connect the ground wire to:
-
gas pipes: might cause explosions or fire if gas leaks.

telephone ground wires or lightning rods: might cause
abnormally high electric potential in the ground during
lightning storms.
-
plumbing pipes: no grounding effect if hard vinyl piping is
