Main cause for refrigerant leakage
is due to defect in the flaring work.
Carry out correct flaring work
using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory or pipes
purchased locally.
2. Measure the distance between the indoor
and the outdoor unit.
3. Cut the pipes a little longer than the
measured distance.
4. Cut the cable 1.5m longer than the pipe
length.

B: Burr removal
1. Completely remove all burrs from the cut
cross section of pipe/tube.
2. 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.
