4. Install Outdoor Unit
4-1. Wiring Instructions for the Outdoor Unit
Regulations on wire size differ from locality to locality.
For field wiring requirements, please refer to your local
electrical codes. Make sure that the installation fully
complies with all local and national regulations.
(1) Disassemble the handle on the outdoor unit right
side plate. (Screw x 1pc)
(2) Take off the wire clamp, then connect and fix the
power connect cord to the terminal of the line bank.
Connect the inter-unit wiring and power line
according to the drawing on the handle.
(3) Be sure to secure the wiring with the clamp.
(Fig. 24a)
NOTE
Use the wire clamp to fix the signal control wire, then
connect to the corresponding connector.
(4) Be sure to size each wire allowing approx. 10 cm longer than the required length for wiring. Store excess wiring
inside the cabinet.
(5) When connections are completed, check that all connections are correct as shown in the wiring system diagram
on the handle.
(6) Be sure to ground the unit according to your local codes.
(7) Reinstall the handle. (Screw x 1pc)
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 7 mm. See the label (Fig. 24b) 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 25 mm. (Fig. 24c)
(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.
For stranded wiring
(1) Cut the wire end with a cutting pliers, then strip the insulation to
expose the stranded wiring about 10 mm and tightly twist the wire
ends. (Figs. 24d and 24e)
(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. 24d)
(4) Place the ring connector wire, and replace and tighten the removed terminal screw using a screwdriver. (Fig. 24f)
