defect in the flaring work. Carry out correct
flaring work using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory or pipes
purchased locally.
2. Measure the distance between the indoor and the outdoor
unit.
3. Cut the pipes a little longer than the measured
distance.
4. Cut the cable 1.5m longer than the pipe length.
B: Burr 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.
C: 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)
D: Flaring work
