Pipe Expanding Method
Note: Improper pipe expanding is the main cause of refrigerant leakage. Expand the
pipe according to the following steps:
(A) Cut the Pipe
Determine the line length based on the distance between the indoor and outdoor air
conditioners. Cut the required cable length with a cable cutter.
(B) Remove the Burrs
Remove the burrs with a shaper. Make sure that the end of the line is pointing
downwards towards the top of the shaper to prevent dust from getting back into the line.
