3.4.3 Drilling a Piping Hole in the Wall
Follow the left or right piping-clearance recommendations.
1. Using a 2-5/8 in. (0.65 mm) hole-core drill bits, drill a hole at either the right or left side of the wall
mounting, Figure 3-13.
• The slant of the hole should be 3/16 to 5/16 of an inch from level with an upward slant on the
indoor-unit side and downward on the outdoor-unit side.
2. Finish-off the newly-drilled hole as shown in Figure 3-13 with a bushing and sleeve covering.
• The sleeve and bushing prevents damage to the tubing/bundling of the piping.
