Before performing any electrical or wiring
work, turn o the main power to the
system.
1. Prepare the cable for connection
a. You must rst choose the right cable
size. Be sure to use H07RN-F cables.
Minimum Cross-Sectional Area of
Power and Signal Cables (For reference)
Rated Current of
Appliance (A)
> 3 and ≤ 6
> 6 and ≤ 10
> 10 and ≤ 16
> 16 and ≤ 25
> 25 and ≤ 32
> 32 and ≤ 40
b. Using wire strippers, strip the rubber jacket
from both ends of the signal cable to reveal
approximately 15cm (5.9") of wire.
c. Strip the insulation from the ends.
d. 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.
2. Unscrew the electrical wiring cover and
remove it.(see the gure of outdoor unit A)
Remove the 8 screws xed on the front
panel and side panel, then take it down
to perform wire connection(see the gure
of outdoor unit B).
3. Connect the u-lugs to the terminals
Match the wire colors/labels with the labels
on the terminal block, Firmly screw the u-lug
of each wire to its corresponding terminal.
4. Clamp down the cable with the cable clamp.
