2. Flaring Work and Connection of Piping

1) Flaring work

Main cause for refrigerant leakage is due to defect in the flaring work. Carry out correct flaring work using the following procedure.

1.Cut the pipes and the cable.

•Use the piping kit accessory or pipes purchased locally.

•Measure the distance between the indoor and the outdoor unit.

•Cut the pipes a little longer than the measured distance.

•Cut the cable 1.5m longer than the pipe length.

4.Flaring work

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

2.Burr removal

•Completely remove all burrs from the cut cross sec- tion of pipe/tube.

•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.

5. Check

•Compare the flared work with figure below.

•If flare is noted to be defective, cut off the flared sec- tion and re-flare it.
