8.1 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.
⚫ 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.
⚫ Putting nut on
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).
