Connecting Pipe Preparation
11.5.1 Pipe Preparation
1. Pipe & Electrical Wire Cutting
● Use cutting tools easily found in the market.
● Measure precisely both outer & inter pipes.
● The length of the pipe should be a little longer
than the actual measured value.
● The wire should be 1.5m longer than the refrigerant
tube.
2. Reaming
● Clean the inside of the inner refrigerant tube.
● While reaming, the tube end must be on the top of the
reamer to prevent any dust going back into the tube.
3. 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.
