thickness
When properly flared, the internal surface
of the flare will evenly shine and be of even
thickness.
After the flare part comes into contact with
the connectors, carefully check the flare
finish.
(3) Piping and Drainage of Indoor Unit
for field supplied tubing and wiring
1) Preparation of Interconnecting
Piping and wiring
1. Cut the pipe and wring cable.
•
Measure the distance between the indoor and the outdoor
unit.
•
Cut the pipes a little longer than measure distance.
•
Cut the cable 5 foot longer than the length of the pipe.
2. Remove burrs.
•
Remove burrs from cut edges of pipe.
•
Turn the pipe end down to avoid metal powder entering the
pipe.
Caution
If burrs are not removed, they will cause refrigerant leakage.
3. Flaring the pipes.
•
Insert the flare nuts, mounted on the connection ports of
both indoor and outdoor unit, onto the copper pipes. Some
nitrogen may leak, when the flare nuts are removed from
the indoor unit, as some nitrogen is charged in the indoor
unit to prevent the inside of the pipe from rusting.
•
Fit the copper pipe end into the bar of flare tool about 1/4”
to 5/8” higher. (See illustration)
•
Make a flare at the end of copper pipe with a flare tool*.
* Use “RIDGID” or equivalent.
