ELECTRIC WIRING WORK
8-1 GENERAL INSTRUCTIONS
• All field-supplied parts, materials, and electrical
w
orks
must conform to local codes.
• Use only copper
w
ire .
• For electrical
w
iring
w
ork, refer to the
Wiring Diagram
Label
attached to the control box lid.
• For remote controller
w
iring details, refer to the installation
manual attached to the remote controller.
• All
w
iring must be performed by an authorized electrician.
• This system consists of multiple indoor units. Mark each
indoor unit as unit A, unit B,and so on, and be sure the ter-
minal board
w
iring to the outdoor unit and BS unit are prop-
erly matched. If controls
w
iring and piping bet
w
een the
outdoor and indoor units are mismatched, a communica-
tions malfunction is likely
.
• An ground leakage circuit breaker capable of shutting
do
w
n the po
w
er supply to the entire system must be
installed.
• Refer to the installation manual attached to the outdoor unit
for the size of po
w
er supply
w
iring connected to the outdoor
unit, the capacity of the circuit breaker and s
w
itch, and
w
ir-
ing instructions.
• Be sure to ground the air conditioner.
DANGER
• Do not ground units to
w
ater pipes, telephone
w
ires, or
lightning rods because incomplete grounding can cause a
severe shock hazard resulting in severe injury or death. Do
not ground to gas pipes because a gas leak can result in an
explosion leading to severe injury or death.

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 con-
troller
w
ire, transmission
w
ire, and the po
w
er supply
w
ire
inside the unit, using conduits for each, so that the
w
ires do
not come into contact
w
ith the opening section of the metal
casing.
• Pass conduits through the
w
all and secure them along
w
ith
the refrigerant pipe in order to prevent external pressure to
transmission
w
ire and po
w
er supply
w
ire.
• Prevent dust from entering into the unit by filling the gap
around the pipe or
w
ire
w
ith corking or putty.
• Arrange the
w
ires and fix the lid firmly so that it does not
float during
w
iring
w
ork.
• Do not clamp remote controller
w
ire and transmission
w
ire
together
w
ith po
w
er supply
w
ire. Doing so may cause mal-
function.
• Remote controller
w
ire, transmission
w
ire, and po
w
er sup-
ply
w
ire should be located at least 5 inches from other
electrical
w
ires.
