Leading out the pipes
• The indoor/outdoor unit connecting pipes can be connected in any of 3 directions. Use a screwdriver to punch out
the knockout part of the piping/wiring panel or base. Wear heavy work gloves to protect yourself from injury while
doing this work. After punching out the knockout hole in a manner which ensures that the pipes and wires will not be
damaged in any way, remove the burrs from around the hole. Use the protective edge guard around the opening.
