Be extra careful not to damage, dent, or deform the pipe while cutting.
This will drastically reduce the heating efficiency of the unit.

Note On Pipe Length
The length of refrigerant piping will affect the performance and energy efficiency of
the unit. Nominal efficiency is tested on units with a pipe length of 16.5ft (5 meters).
Refer to the table below for specifications on the maximum length.

Refrigerant Piping Connection Instructions
Improper pipe shorten or expanding might cause refrigerant leakage. Please take
extra care to cut and flare them properly to ensure the efficient operation and
minimize the need for future maintenance.
a. Cut pipes
● Measure the distance between the indoor and outdoor units.
● Using a pipe cutter, cut the pipe a little longer than the measured distance.
● Make sure that the pipe is cut at a perfect 90° angle.
