Work procedure
Straighten the coiled copper pipe.
Key point
Uncoil the pipe.
(Reason)
• It is difficult to cut the coiled pipe
correctly, which increases the
chance of failure.
Cut the pipe with the pipe cutter.
Use the reamer to remove burrs
from the cut surface of the pipe.
Clear out the inside of the pipe by
tapping on the end with a
screwdriver.
Insert the flare nut.
1. Position the blade of the cutter
so that it will cut the pipe at a
perpendicular angle.
2. Rotate the pipe cutter to the
left to cut the pipe.
3. Move the pipe cutter slowly.
1 . Keep the opening of the pipe
facing downwards.
2. Be careful not to scratch the
inner surface of the pipe.
Make sure that all scraps of metal
are out of the tube by lightly
tapping on the tube while the
opening is pointing down.
• The cut surface will be at an
angle.
• The cutter will bite too tightly.
• The copper pipe will be
deformed.
• Scraps will get inside of the
pipe.
• A gas leak could result.
• Metal scraps in the tube can
damage the compressor.
• If the scraps adhere to the
flared region, a gas leak may
result.
Be certain to insert the flare nut
before beginning the flare
process.
• The flare nut will not fit inside
the copper pipe after the flare
process.
