It is also possible to cover the end of the pipe temporarily using high quality adhesive tape.
•
Do not wind and unwind the pipe continuously, as the properties of the copper for refrigeration pipes are altered,
making it more rigid and brittle.
Cutting
Define the necessary length of pipe and add a few more centimetres to give yourself enough margin in case the cut has to
be repeated.
Cut the pipe using a pipe cutter.
C A U T I O N
Ensure the pipe cutter rollers remain perfectly seated on the
copper pipe.
Remove any internal burrs arising from the pipe cutter using a pipe
reamer.

•
While making the cut, slant the pipe downwards to prevent burrs or shavings from falling inside the pipe.
•
Do not use hand saws, circular saws, abrasive grinders or other tools that generate shavings.
•
Strictly follow national or local regulations regarding occupational health and safety.
•
Wear appropriate means of protection during cutting or brazing operations and installation (gloves, eye
protection, etc).
