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 main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in the fixed
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 attached to the outdoor unit for
the size of power supply electric wire connected to the outdoor
unit, the capacity of the earth leakage circuit breaker and fuse,
and 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 
used.

How to connect wiring 

(See figure 10)

Inter unit wiring
Remove the control box lid (1) and connect the inter unit wiring
terminal block inside with the matching numbers and connect
the ground wire to the grounding terminal. While doing this, pull
the wires inside through the hole in the casing and clamp the
wires along with other wires using a clamp as indicated in the
figure.

Remote controller wiring
Remove the control box lid (1) and pull the wires inside through
the hole in the casing and connect to the remote controller
wiring terminal block. Securely fix the wiring using a clamp as
indicated in the figure.

After connection
Attach the small sealing (supplied with the unit) around the
cables to prevent infiltrating of water from the outside into the
unit. If two or more cables are used, divide the small sealing into
the required number of pieces and wrap them around all the
cables.

Attach the control box lid

Precautions

1

Observe the notes mentioned below when wiring to the power
supply terminal board.

-

Use a round crimp-style terminal for insulation sleeve for 
connection to the terminal block for wiring the units. When 
none are available, follow the instructions below.

-

Do not connect wires of different gauge to the same power 
supply terminal. (Looseness in the connection may cause 
overheating.)

-

When clamping wiring, use the clamps (delivered with the 
unit) to prevent outside pressure being exerted on the wiring 
connections. Tie up firmly. When doing the wiring, make sure 
the wiring is neat and does not cause the control box to stick 
up. Close the cover firmly.
