(5) Use shielded wires for inter-unit control wiring (c)
and ground the shield on both sides, otherwise
misoperation from noise may occur. (Fig. 5-8)

WARNING
Loose wiring may cause the terminal to overheat or result
in unit malfunction. A fire hazard may also occur. Therefore,
ensure that all wiring is tightly connected.
When connecting each power wire to the terminal, follow the
instructions on "How to connect wiring to the terminal" and
fasten the wire securely with the terminal screw.
How to connect wiring to the terminal
■ For stranded wires
(1) Cut the wire end with cutting pliers, then strip the insulation
to expose the stranded wire about 10 mm and tightly twist
the wire ends. (Fig. 5-9)

(2) Using a Phillips head 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 pressure terminal.
(4) Put the removed terminal screw through the ring pressure

7. HOW TO PROCESS TUBING

The liquid tubing side is connected by a flare nut, and the gas
tubing side is connected by brazing.

7-1. Connecting the Refrigerant Tubing

Use of the Flaring Method
Many of conventional split system air conditioners employ the
flaring method to connect refrigerant tubes that run between
indoor and outdoor units. In this method, the copper tubes are
flared at each end and connected with flare nuts.
Flaring Procedure with a Flare Tool
(1) Cut the copper tube to the required length with a tube
cutter. It is recommended to cut approx. 30 – 50 cm longer
than the tubing length you estimate.
(2) Remove burrs at each end of the copper tubing with a
tube reamer or file. This process is important and should
be done carefully to make a good flare. Be sure to keep
any contaminants (moisture, dirt, metal filings, etc.) from
entering the tubing. (Figs. 7-1 and 7-2)

NOT E

When reaming, hold the tube end downward and be sure that
no copper scraps fall into the tube. (Fig. 7-2)
(3) Remove the flare nut from the unit and be sure to mount it
on the copper tube.
(4) Make a flare at the end of the copper tube with a flare tool.
(Fig. 7-3)
NOT E
A good flare should have the following characteristics:
● inside surface is glossy and smooth
● edge is smooth
● tapered sides are of uniform length
