Connecting wiring to outdoor unit:
1
Remove the wiring access cover on the
outdoor unit.
2
Drill a hole through the plastic plug cap
appropriate for the passage of connecting cable
(for low voltage line).
3
Pass the connecting cable through hole.
4
Properly connect the wire onto the terminal
block.
5
Fix the connecting cable with the clamp cord
provided on the unit to avoid strain at the
terminal when the connecting cable is pulled
outside by up to a 35-pound weight.
6
Wind vinyl tape over the connecting cable for
sealing between the surface of the connecting
cable and cap.
7
Mount the taped part of the cable on the cap.
8
Mount the holed cap with the wound cable on the
conduit panel.
WARNING:
Loose wiring may cause the terminal to
overheat or result in unit malfunction. A fire hazard
may also exist. Be sure all wiring is tightly connected.
How to connect wiring to the terminals:
■For solid core wiring (or F-cable)
1
Cut the wire end with a wire cutter or wire-cutting
pliers, then strip the insulation to expose the solid
wire about 15/16².
2
Using a screwdriver, remove the terminal
screw(s) on the terminal plate.
3
Using pliers, bend the solid wire to form a loop
suitable for the terminal screw.
4
Shape the loop wire properly, place it on the
terminal plate and tighten securely using a
screwdriver.
■For strand wiring
1
Cut the wire end with a wire cutter or wire cutting
pliers, then strip the insulation to expose the
strand wiring about 3/8².
2
Using a screwdriver, remove the terminal
screw(s) on the terminal plate.
3
Using a round terminal fastener or pliers,
securely clamp each stripped wire end with a
round terminal.
4
Position the round terminal wire, and replace
and tighten the terminal screw using a
screwdriver.
