Flaring Work and Connection of Piping

Flaring Work and Connection of Piping

Flaringwork

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.

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 (5.0ft) 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 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)

Flaring work

Carry out flaring work using flaring tool as shown below.

Firmly hold copper pipe in a die in the dimension shown in the table above.
