Electric wiring work

General instructions
I All field supplied parts and materials and electric works must
conform to local codes.
Use copper wire only.
I
Follow the "Wiring diagram" attached to the switch box cover to
I
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".
I All wiring must be performed by an authorized electrician.
I A circuit breaker capable of shutting down power supply to the
entire system must be installed.
This system consists of multiple indoor units. Mark each indoor
I
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.

How to connect wiring
Open the switch box cover, as shown in figure 7, to make
I
connections.
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.
Keep total current of crossover wiring between indoor units less
2.
than 12A. Branch the line outside the terminal board of the unit
in accordance with electrical equipment standards, when using
two power wiring of a gauge greater than 2 mm
The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.
3. Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
4. Remote controller cords and wires connecting the units should
be located at least 50 mm away from power supply wiring. Not
following this guideline may result in malfunction due to electrical
noise.
5. For the remote controller wiring, refer to the "Installation manual
of the remote controller" supplied with the remote controller.
6. Never connect the power supply wiring to the terminal board for
transmission wiring. This mistake could damage the entire
system.
7. Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worse case, electric shock
or fire.
