WARNING
•
Sufficient structural support must be determined prior
to locating and mounting the curb and package unit.
•
Ductwork must be constructed using industry
guidelines. The duct work must be placed into the
roof curb before mounting the package unit. Our full
perimeter curbs include duct connection frames to be
assembled with the curb. Cantilevered type curbs
are not available from the factory.
•
Curb insulation, cant strips, flashing and general
roofing material are furnished by the contractor.
The curbs must be supported on parallel sides by roof mem-
bers. The roof members must not penetrate supply and re-
turn duct opening areas as damage to the unit might occur.
NOTE:
The unit and curb accessories are designed to allow
vertical duct installation before unit placement. Duct
installation after unit placement is not recommended.
