WARNING
WRITE DOWN THE SPECIFICATIONS OF THE
FUSES.
The air conditioner board (PCB) is equipped
with a fuse for overcurrent protection. Fuse
specifications are printed on the circuit board,
for example:
Indoor unit: T5A/250VAC
NOTE: The fuse is ceramic.
1 Prepare the cable for connection:
– Using a wire stripper, strip the rubber sheath at
both ends of the cable and expose approximately
15 cm of the internal conductors.
– Strip the insulation sheath at the ends of the
conductors.
– Using a crimping tool, crimp U-type wire terminals
to the ends of the conductors.
m
CAUTION
When crimping, clearly identify live cables ("L")
and other cables.
2 Open the front panel of the indoor unit.
3 Take the cover off the electrical panel on the indoor
unit with a screwdriver. This will give you access to the
terminal block.
l
WARNING
All connections must be made exactly as
shown in the wiring diagram on the inside of
the terminal block cover of the indoor unit.

Match the colours/labels of the cables to the labels
on the terminal block, then screw the U-shaped wire
terminal of each cable firmly to the corresponding
terminal block. Refer to the serial number and wiring
diagram on the cover of the electrical panel.
6 Route the electrical cables through this opening,
proceeding from the back of the unit to the front.

of the cables to the labels on the terminal block,
connect the U-shaped terminals and screw each
cable securely to the corresponding terminal.
