Flaring Work

Main cause for gas leakage is due to defect of flaring work. Carry out correct flaring work in the following proce-

dure.

Cut the pipes and the cable.

1. Use the piping kit accessory or the pipes purchased

locally.

2. Measure the distance between the indoor and the out-

door unit.

3. Cut the pipes a little longer than measured distance.

4. Cut the cable 1.5m longer than the pipe length.

Burrs removal

1. Completely remove all burrs from the cut cross section

of pipe/tube.

2. While removing burrs put the end of the copper

tube/pipe in a downward direction while removing

burrs location is also changed in order to avoid drop-

ping burrs into the tubing.

then put them on pipe/tube having completed burr

removal.

(not possible to put them on after finishing flare work)
