Drilling the Piping Hole in the Wall
Follow all piping clearance recommendations.
1. Using a 2-5/8" hole core drill bit, drill a hole at the selected location. Avoid
obstructions in the wall such as electrical wires or conduits and water or gas
pipes.
• The slant of the hole must be 3/16" to 5/16" from level with the slant being
upward on the indoor unit side and downward on the outdoor unit side.
2. Finish off the newly drilled hole as shown with bushing and sleeve covering.
• Sleeve and bushing prevents damage to the tubing/bundling of the piping.
See Refrigerant Piping Connections for Indoor Unit for information on piping installation.

• Go to the Electrical Connections section of this manual for information on conduit /
