5.4 Refrigerant pipe connection

5.4.1 Flaring work

Main cause for refrigerant leakage is due to
defect in the flaring work. Carry out correct
flaring work using the following procedure:
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.

cut cross section of pipe/tube.

pipe in a downward direction as
you remove burrs in order to avoid
dropping burrs into the tubing.
