1. Prepare the cable for connection:
• Using wire strippers, strip the rubber jacket from both
ends of signal cable to reveal about 40mm (1.57in) of
the wires inside.
• Strip the insulation from the ends of the wires.
• Using wire crimper, crimp u-type lugs on the ends of
the wires.
2. Open and fix the position of the panel, then, open the
covers of the two lock blocks, unscrew the screw , then
hold both sides of the lower panel in the place marked
"PULL", pull it upwards to release the buckles, then take
the lower panel down
3. Open the wire box cover to connect the cable.
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.
6. Feed the signal wire through this slot, from the back of
the unit to the front.
7. Facing the front of the unit, connect the wire according
to the indoor unit's wiring diagram, connect the u-lug and
firmly screw each wire to its corresponding terminal.
First open the front panel, then remove
the lower panel.

NOTE: If the size of the cable is too big, remove the middle
small plastic knock-out panel to create a slot through
which the cable can exit. If you want to remove the chassis
or drain hose, please remove the rat baffle first.
In North America：
First remove the knok-out panel to create a slot through
whick the conduit tube can install. Then make the cable
through the conduit tube and connect to the indoor unit.
8. After checking to make sure every connection is secure,
use the cable clamp to fasten the signal cable to the unit.
Screw the cable clamp down tightly.
9. Replace the wire cover on the front of the unit, and the
plastic panel on the back.
NOTE:
• 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
