ELECTRIC WIRING WORK
General instructions
All field supplied parts and materials and electric works must
conform to local codes.
Use copper wire only.
Follow the 'Wiring diagram' attached to the unit body to wire the
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.
A circuit breaker capable of shutting down power supply to the
entire system must be installed.
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 attached to the outdoor unit for
the size of power supply electric wire connected to the outdoor
unit, the capacity of the circuit breaker and switch, and wiring
instructions.
Be sure to ground the air conditioner.
Do not connect the ground wire to gas pipes, water pipes,
lightning rods, or telephone ground wires.
Gas pipes: might cause explosions or fire if gas leaks.
•Water pipes: no grounding effect if hard vinyl piping is used.
•Telephone ground wires or lightning rods: might cause
abnormally high electric potential in the ground during lightning
storms.

WIRING EXAMPLE AND HOW TO SET THE
REMOTE CONTROLLER
How to connect wiring (See figure 22)
Wiring between units and ground wire
Remove the control box lid and connect wires of matching
number to the power supply terminal block (4P) inside. (See C).
And connect the ground wire to the terminal block. In doing this,
pull the wires inside through the hole and fix the wires securely
with a field supplied clamp. (See B).
Give enough slack to the wires between the clamp and power
supply terminal block. (Use the figure as a guide and allow at
least 80 mm for removing the sheath.)
Pull the wires inside through the hole and connect to the
terminal block for remote controller (6P). (See A). (no polarity)
Securely fix the remote controller cord with a field supplied
clamp.
Give enough slack to the wires between the clamp and the
terminal block for the remote controller.
After connection, attach sealing material. (See D).
Be sure to attach the sealing material to prevent the infiltration of
water, as well as of any insects or other small creatures. Other-
wise a short circuit may occur inside the control box. (See D).
