piping connection
Unit comes with 16.4 feet tubing bundle. It is not recommended to cut. If too
long, loop for excess.

Flaring work

due to defect in the flaring work.
Carry out correct flaring work using the
following procedure:
1. Cut the pipes and the cable.
A) Use the piping kit accessory or
pipes purchased locally.
B) Measure the distance between the
indoor and the outdoor unit.
C) Cut the pipes a little longer than the
measured distance.
D) Cut the cable 4.92 feet longer than
the pipe length.
2. Burr removal
A) Completely remove all burrs from
the cut cross section of pipe/tube.
B) Put the end of the copper
tube/pipe in a downward direction
as you remove burrs in order to
avoid dropping burrs into the
tubing.
3. Put nut on.
Remove flare nuts attached to
indoor and outdoor unit, then put
them on pipe/tube having
completed burr removal.fit is not
possible to put them on after flaring
work)
