Sealing Refrigerant Lines and Electrical Harnesses
Once the access hole has been cut and all refrigerant hoses and electrical harnesses have been routed and connected,
the hole must be sealed properly by following these steps:
1. Position rubber grommet around the access hole to determine cut length.
2. Cut the grommet so the ends touch and no sharp edges of the wall are exposed.
3. Cut one piece of grommet for each side of the box.
4. Fill hole with expandable foam (installer supplied). Spray the foam in between the hoses and harnesses so the hole
is completely filled with foam.
5. Once the foam has cured, trim excess foam around hoses and harnesses so the foam is flush with the wall or roof.
6. Seal the foam hole from moisture with either silicone sealant or plumbers putty.
