(The pipe cover needs to be removed before
performing piping and wiring works.)
NOTES:
•
Do not run the power supply wiring and
communication wiring through the same conduit
tube.
Moreover, keep at least 5cm between the power
supply wiring and communication wiring.
•
Pull out each wire from each corresponding knockout
hole. Cut an "X" in rubber bush (accessory) and

WARNING
•
The ELB (earth leakage breaker), FUSE and S (main
switch) must be installed for each outdoor unit and
also for each indoor unit group. If not, it may cause
an electrical shock or fire.
•
Perform the electrical work according to the
regulation of each region and the Installation and
Maintenance Manual, and the dedicated electrical
circuit must be used. If the electrical wiring work
is performed incorrectly or there is a capacity
shortage of the power circuit, it will damage
electrical parts and cause an electric shock or a
fire.
•
Check that the ground wire is securely connected.
If the unit is not correctly grounded, it may lead to
an electrical shock.
Do not connect the ground wiring to a gas piping,
water piping, lighting conductor or ground wiring
for telephone.
•
The power sources for the indoor unit and outdoor
unit should be supplied respectively.
•
The power source for each indoor unit group
should be supplied respectively.
