ELECTRIC WIRING WORK

8-1 GENERAL INSTRUCTIONS
• All fi eld supplied parts and materials and electric works must
conform to local codes.
• Use copper wire only.
• For electric wiring work, refer to also "Wiring diagram label"
attached to the control box lid.
• For remote controller wiring details, refer to the installation
manual attached to the remote controller.
• All wires must be performed by an authorized electrician.
• An earth leakage circuit breaker capable of shutting down
power supply to the entire system must be installed.
• Refer to the installation manual attached to the outdoor unit
for the size of power supply wiring connected to the outdoor
unit, the capacity of the circuit breaker and switch, and wiring
instructions.
• Be sure to ground the air conditioner.
DANGER
• Do not ground units to water pipes, telephone wires or
lightning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, and
to gas pipes because a gas leak could result in an explosion
which could lead to severe injury or death.

9. WIRING EXAMPLE AND HOW TO SET
THE REMOTE CONTROLLER
9-1 HOW TO CONNECT WIRES
CAUTION
• Even if the control box lid is removed, pull the remote control-
ler wire, transmission wire and the power supply wire inside
the unit using conduits for each, so that the wires do not come
into contact with the opening section of the metal casing.
• Pass conduits through the wall and secure along with the
refrigerant pipe in order to prevent external pressure being
applied to transmission wire and power supply wire.
• To avoid short circuits in the electric parts box, be sure to apply
the sealing material or putty (not included) to the wiring hole to
prevent the infi ltration of water, insects or other small creatures.
• Arrange the wires and fi x a lid fi rmly so that the lid does not
fl oat during wiring work.
• Do not clamp remote controller wire and transmission wire
together with power supply wire. Doing so may cause mal-
function.
• Remote controller wire, transmission wire and power supply
wire should be located at least 5 in. from other electric wires.
Not following this guideline may result in malfunction due to
electrical noise.
<Method of wiring power supply, units and connect-
ing remote controller wiring> (Refer to Fig. 26)
• Attaching the resin bush
Attach the resin bush (10) for remote controller wiring.
• Installlation of conduit
Insert the conduit for power supply wire in the conduit hole,
and fi x it with the lock nut.

Resin bush (10)
• Power supply wire
Holding the control box lid, loosen the 2 securing screws,
remove the control box lid, match up the phases on the power
supply terminal block inside (2P), and make the connections.
After this is done, use the attached clamp (4) to bind wire
between units to the anchor point. (Refer to Fig. 27)
• Remote controller wire and transmission wire
Holding the control box lid, loosen the 2 securing screws,
remove the control box lid.
Thread the remote controller wire and transmission wire
through the insulating tube (11) and secure with the clamp
(4), and cut off the insulating tube (11) to suitable length. Pull
the wires inside through resin bush and connect the wires to
the transmission terminal block (6P) inside the control box.
After connecting, use the clamp (4) to bind the remote con-
troller wire together with the transmission wire to the anchor.
