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.

cutter, taking care to ensure that the cut edge remains
at a 90° angle with the side of the pipe. Refer to the
