General instructions
All field supplied parts and materials and electric works must
I
conform to local codes.
Use copper wire only.
I
I 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.
I
A circuit breaker capable of shutting down power supply to the
I
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.
I This system consists of multiple indoor units. Mark each indoor
unit as unit A, unit B..., and be sure the terminal board wiring to
the outdoor unit and HR box are properly matched. If wiring and
piping between the outdoor unit and an indoor unit are
mismatched, the system may cause a malfunction.

IRING EXAMPLE AND HOW TO SET THE
REMOTE CONTROLLER
How to connect wiring
(See figure 12)
I Power supply wiring
Remove the switch box lid (1) and connect the wires to the
power supply terminal board inside. While doing this, pull the
wires inside through the rubber bush A and clamp the wires
along with other wires using clamp A, untightening the clip of
clamp A by pressing. After the connection, tighten clamp A as
before.
Unit wiring and remote controller wiring
I
Remove the switch box lid (2) and pull the wires inside through
the rubber bush B and connect to the terminal board for unit
transmission wiring.
I 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.

Precautions
1 Observe the notes mentioned below when wiring to the power
supply terminal board.
• Do not connect wires of different gauge to the same power supply
terminal. (Looseness in the connection may cause overheating.)
• When connecting wires of the same gauge, connect them
according to the figure.
Use the specified electric wire. Connect the wire securely to the
terminal. Lock the wire down without applying excessive force to
the terminal. (tightening torque 1.31 Nm ±10 %)
