When connecting each power wire to the corresponding terminal, fol-
low the instructions “How to connect wiring to the terminal” and fasten
the wire securely tight with the fixing screw of the terminal plate.
How to connect wiring to the terminal
a) For Indoor Unit
(1) Cut the wire end with a cutting pliers, then strip the insulation to
expose the wire about 9/32" (7 mm). See the label (Fig. 9) near the
terminal plate.
(2) Using a screwdriver, loosen the terminal screw on the terminal
plate.
(3) Insert the wire and tighten the terminal screw completely using a
screwdriver.
b) For Outdoor Unit
For solid core wiring (or F-cable)
(1) Cut the wire end with a cutting pliers, then strip the insulation to
expose the solid wire about 15/16"
(25 mm). (Fig. 10)
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
plate.
(3) Using the 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 fix
it securely with the removed terminal screw using a screwdriver.
Loose wiring may cause the ter-
minal to overheat or result in unit
malfunction. A fire hazard may
also exist. Therefore, be sure all
wiring is tightly connected.
