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.
a. Using wire strippers, strip the rubber jacketfrom
both ends of the signal cable
to reveal approximately 15cm (5.9") of wire.
b. Strip the insulation from the ends.
c.
Using a wire crimper, crimp u-lugs on the
ends.
NOTE:
When connecting the wires, strictly follow the
wiring diagram found inside the electrical box cover.
1.
Remove the electric cover of the outdoor unit. If there
is no cover on the outdoor
unit, take off the bolts from the maintenance boardand

Match the wire colors/labels with the labels on the
terminal block. Firmly screw the u-lug of each wire to
its corresponding terminal.
3. Clamp down the cable with the cable clamp.
4. Insulate unused wires with electrical tape.
