INSTALLATION INSTRUCTION

4 Please refer to the following directions

when connecting the indoor unit and the

wired remote controller together.

1) Please connect the cables as shown in the

figure below when connecting the plug

type cable from the indoor unit’s C/BOX

and the housing type of the extension

cable.

2) When connecting Terminal Blocks of the in-

door C/BOX and the wired remote con-

troller with the extension cable, refer to the

steps below.

① Remove the screw on the cable which is

fastened to the wired remote controller’s

Terminal Block by loosening with a screw

driver.

② Remove the housing of the provided 32ft

extension cable with a cutting nipper and

peel it as shown in the figure below. (when

purchasing the extension cable at the site

directly, please peel it as shown in the fig-

ure below.)

③ Make sure each wire is securely fastened

under each screw terminal and the wires

are not in contact with each other.

④ Please connect the Terminal blocks of in-

door unit’s C/BOX and wired remote con-

troller by referring to the images and

contents shown below.

Connect the yellow(signal) part of the wired

remote controller’s terminal block and the

‘YL’ part of the indoor unit’s terminal block.

Connect the red(12V) part of the wired re-

mote controller’s terminal block and the

‘RD’ part of the indoor unit’s terminal block.

Connect the black(GND) part of the wired

remote controller’s terminal block and the

‘BK’ part of the indoor unit’s terminal block.

* In case of loosened screws or insufficient

contact between the terminal and the wire,

remote controller may not function properly.

* When the power is off on the remote con-

troller, check the connection between the

remote controller and Terminal Block.

* Use an appropriate screwdriver for tighten-

ing the terminal screws. A screwdriver with

a small head will strip the head and make

proper tightening impossible.

* Over-tightening the terminal screws may

break wires and terminal block structure.
