Bundling and Cutting Line

Indoor Unit Drain Pan
1. Install a drain pan if required by local code.
2. Figure 51 shows typical drain pan installation.
Checking the Indoor Unit Drain Hose for Leaks
1. Pour a glass of water on the evaporator.
2. Verify that the water flows appropriately through and out of the
drain hose of the indoor unit without any leaks.
Bundling and Cutting Line
Piping and cabling must be insulated and bundled together correctly
for safety and usage. Follow proper methods and procedures as
outlined here and on the next pages to ensure installation and piping
are correctly installed.
1. Piping must be fully 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 (see figure below).
4. Wrap the rear piping house 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 plenty of insulation on all refrigerant and drain piping to
ensure condensate does not form and cause damage to walls, floors, etc.
