Bundling
If a conduit or piping set cover is not used on the connection from
the outdoor unit to the interior, bundle both separately insulated
refrigerant pipes, the drain hose, and outdoor unit to indoor unit
communication / connection (power) cable together with wide vinyl
tape.
1. Both piping must be fully and separately encased in insulation
material: Overlap the field installation piping insulation material
and the indoor unit piping insulation material.
2. Bind together the two pipes, using vinyl tape. Make sure there
are no gaps during the binding.
3. Be sure the cutting line is placed upward.
4. Wrap the rear piping section with narrow vinyl tape.
5. Continue to wrap the indoor unit pipe as connected to the outdoor
connection pipe.
6. Using a wider vinyl tape, bundle the piping and drain hose
together.
• Tape must be sufficient to cover the piping in order to fit into the
rear piping housing area at the back of the indoor unit.
• Always include insulation on all refrigerant and drain piping to en-
sure condensate does not form and cause damage to walls, floors,
etc.
• For systems with wiring greater than 130 feet, see the “Communica-
tion / Connection (Power) Cable Specifications from Outdoor Unit to
Indoor Unit” in the Electrical System Installation section for informa-
tion.
