WARNING Loose wiring may cause the terminal to overheat or result

in unit malfunction. A fire hazard may also exist. There- fore, be sure all wiring is tightly connected.

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. 28) 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.

(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.

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. 30

 

and 31)
