Flaring Work
Main cause for gas leakage is due to defect of flaring work. Carry out correct flaring work in the following procedure.
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 outdoor unit.
3. Cut the pipes a little longer than measured distance.
4. Cut the cable 1500mm 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 dropping burrs into the tubing.

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 finishing flare work)
