Flaring Work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the follow-
ing 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 out-
door unit.
3. Cut the pipes a little longer than measured distance.
4. Cut the cable 1.5m(59.1in) longer than the pipe length.
Burrs 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 drop-
ping 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)
