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.

Attach the earth leakage circuit breaker and fuse to the power
supply line.

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.

This system consists of multiple indoor units. Mark each indoor
unit as unit A, unit B..., and be sure the terminal block wiring to
the outdoor unit and BS unit are properly matched. If wiring and
piping between the outdoor unit and an indoor unit are
mismatched, the system may cause a malfunction.

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)

Power supply wiring
Remove the control box lid (1) and connect the wires to the
power supply terminal block inside (L, N) 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.

Unit transmission wiring and remote controller wiring
Remove the control box lid (1) and pull the wires inside through
the hole in the casing and connect to the terminal block for unit
transmission wiring (F1, 

F2) and remote controller wiring

(P1, P2). 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 block.

-

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.
