indoor and the outdoor unit.
C) Cut the pipes a little longer than the
measured distance.
D) Cut the cable 1.5m longer than the
pipe length.
2. Burr removal
A) Completely remove all burrs from
the cut cross section of pipe/tube.
B) Put the end of the copper.
tube/pipe in a downward direction
as you remove burrs in order to
avoid dropping burrs into the
tubing.

indoor and outdoor unit, then put
them on pipe/tube having
completed burr removal.(not
