Flaring work
Main cause for refrigerant leakage is
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 1.5m 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. Putting nut on.
A) Remove flare nuts attached to
indoor and outdoor unit, then put
them on pipe/tube having
completed burr removal.(not
possible to put them on after flaring
work)
