never tap with a hammer near the pipe outlet.
Otherwise, it may cause product damage such as
warping of the cabinet.
• After connecting the pipes with pipe outlet, plug the
space around the pipes.
• After connecting the pipes, proceed exactly as directed in
the guide to prevent interference with the internal parts.
• Tighten the nuts to the specified torques. If overtightened,
the nuts could be broken so refrigerant may leak.
• Protect or enclose refrigerant tubing to avoid
mechanical damage.
• After installing pipes, block the unused knock hole
to prevent small animal from entering. However, the
radiant heat hole(A) should be able to intake air.
Step 6 Optional: Cutting and flaring

2 If you wish to shorten the pipes, cut it with a pipe
cutter, taking care to ensure that the cut edge remains
at a 90° angle with the side of the pipe. Refer to the
illustrations below for examples of edges cut correctly
and incorrectly.
