FLARING WORK AND CONNECTION OF PIPING

ENGLISH

Flaring work

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

following procedure.

Cut the pipes and the cable

- Use the piping kit accessory or the pipes pur-

chased locally.

- Measure the distance between the indoor

and the outdoor unit.

- Cut the pipes a little longer than measured

distance.

- Cut the cable 1.5m longer than the pipe

length.

Burrs removal

- Completely remove all burrs from the cut

cross section of pipe/tube.

- 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)
