Step 6: Connect signal cable
The signal cable enables communication between
the indoor and outdoor units. You must first
choose the right cable size before preparing it for
connection.

CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal
cable, fuse, and switch needed is determined
by the maximum current of the unit. The
maximum current is indicated on the nameplate
located on the side panel of the unit. Refer to
this nameplate to choose the right cable, fuse,
or switch.

TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner' s circuit board (PCB) is
designed with a fuse to provide overcurrent
protection. The specifications of the fuse
are printed on the circuit board, such as:
T3.15A/250VAC, T5A/250VAC, etc.
1. Prepare the cable for connection:
a. Using wire strippers, strip the rubber jacket
from both ends of signal cable to reveal
about 15cm (6in) of the wires inside.
b. Strip the insulation from the ends of the
wires.
c. Using wire crimper, crimp u-type lugs on
the ends of the wires.
PAY ATTENTION TO LIVE WIRE
While crimping wires, make sure you clearly
distinguish the Live ("L") Wire from other wires.
2. Open front panel of the indoor unit.
3. Using a screwdriver, open the wire box cover
on the right side of the unit. This will reveal
the terminal block.
The Wiring Diagram is located
on the inside of the indoor unit's
WARNING
ALL WIRING MUST PERRFORMED STRICTLY
IN ACCORDANCE WITH THE WIRING
DIAGRAM LOCATED ON THE INSIDE OF THE
INDOOR UNIT S WIRE COVER. '
4. Unscrew the cable clamp below the terminal
block and place it to the side.
5. Facing the back of the unit, remove the plastic
panel on the bottom left-hand side.
