INSTALLATION
Installing for Condensate Drainage / Drilling the Piping Hole
Installing for Condensate
Drainage
• It is very important to include a slope for indoor unit
installation to ensure proper condensate drainage
Drilling the Piping Hole
Follow all piping clearance recommendations.
1. Using a 2-5/8 inch hole core drill bit, drill a hole fol-
lowing installation guidelines and application needs. 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 inches to 5/16 inches 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 to prevent dam-
age to the insulation and piping.
• Sleeve and bushing prevents piping / bundling damage.
• See Refrigerant Piping Connections for Indoor Unit for information on piping installation.
• See the Refrigerant Piping Connections section of this manual for information on indoor unit
piping connection installation.
• See the Electrical Connections section of this manual for information on conduit / electrical wiring to the indoor unit.
