Use only copper pipes with the correct wall thickness -
please refer to your usual copper pipe supplier for detail
Make sure you cut the copper pipe with a proper pipe cutter only
Remove any burrs with the utmost care
Make sure that no swarf or other impurities get into the piping
When brazing make sure that Nitrogen (OFN) is used at all times
Brazed joints must be bare and clean
The importance of correct brazing
Brazed joints should only be made using Nitrogen
(OFN) as without it carbon deposits are left on the
pipe surface. The carbon deposits are then washed
off of the surface of the pipe when the refrigerant
is circulated and it then travels with the
refrigerant.
Carbon deposits can cause the refrigerant
and refrigeration unit oil to decompose.
This is likely to result in operation
defects and warranty will become null
and void.
