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 1.5m(59.1 in) 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.

unit, then put them on pipe/tube having completed

work)
