PIPE & ELECTRICAL WIRE CUTTING
●
Use cutting tools easily found in the market.
●
Measure precisely both outer & inner pipe.
●
Provide a little bit longer pipe than the measurement.
●
Wire must be 1.5 m. longer than the refrigerant tube.
■
FLARING THE PIPE END
■
REAMING
●
Clean 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.
●
Flare both ends of the pipe with flaring kit by fitting the
flare nut on the pipe before flaring. Set the die on the
pipe so that pipe end is 0.5 mm. above top of the die.
Check if the pipe end is even and perfectly round.
