Refrigerant Piping
Cut the pipes
- Use the accessory piping kit or the pipes
purchased locally.
- Measure the distance between the indoor
and the outdoor unit.
- Cut the pipes a little longer than measured
distance.
Burrs removal
- Completely remove all burrs from the cut
cross section of pipe/tube.
- Put the end of the copper tube/pipe to
downward direction as you remove burrs in
order to avoid to let burrs drop in the tubing.
Pipe brazing
- Always make sure to flow Nitrogen at
0.2kgf/cm
2
within the pipe while brazing.
- If the brazing is done without flowing
Nitrogen, it can generate a thick oxidized
coating within the pipe to interfere with normal
operation of valve and compressor etc.
Insulation
- Use insulation material with high thermal
resistance and rated for the anticipated
operating temperature range.
- When installed in humid environment, use
thicker insulation material as specified by
system designer.
