12.5 Connecting Pipe Preparation
12.51 Pipe Preparation
Pipe & Electrical Wire Cutting
1. Use cutting tools easily found in the market.
2. Measure precisely both outer & inter pipes.
3. The length of the pipe should be a little longer
than the actual measured value.
4. The wire should be 1.5m longer than the
refrigerant tube
Reaming
1. Clean the inside of the inner refrigerant tube.
2. While reaming, the tube end must be on the top of
the reamer to prevent any dust going back into the
tube.
Flaring the Pipe End
Flare both ends of the pipe with flaring kits by
fitting the flare nut on the pipe before flaring. Set the die
on the pipe in the way that the pipe end is 0.5mm above
the top of the die. Then, check if the pipe end is even and
perfectly round or not.
