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. 

N

ot follo

w

ing this guideline may result in 

malfunction due to electrical noise.

Method of wiring power supply, units, and connecting
