When connecting each power wire to the corresponding
terminal, follow 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. 26) 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 com-
pletely using a screwdriver.
b) For
O
utdoor Unit
I
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. 27)
(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 termi-
nal plate and fix it securely with the removed termi-
nal screw using a screwdriver.
I
For stranded wiring
(1) Cut the wire end with a cutting pliers, then strip the
insulation to expose the stranded wiring about 3/8"
(10 mm) and tightly twist the wire ends. (Figs. 28
and 29)
(2) Using a screwdriver, remove the terminal screw(s)
on the terminal plate.
(3) Using a ring connector fastener or pliers, securely
clamp each stripped wire end with a ring connector.
(Fig. 28)
