Sealing Holes
Proper sealing of all holes drilled into the cargo box is very important. Air leaks will greatly affect the performance of
the unit and water leakage can damage or ruin the cargo.
All component mounting holes and access holes for electrical and refrigerant hoses must be sealed both inside and
outside the cargo box.
Sealing Methods
Any of the following sealing methods are acceptable:
• Silicone Sealant (neutral/alcohol cure, exterior grade, flexible, non-hardening)
• Strips of foam rubber material applied between surfaces (closed cell foam only)
• Molded gaskets (for specific applications)
• Expandable Spray Foam (for larger holes)
• Plumbers putty
All unit mounting holes must be sealed both inside and outside the cargo box.
