Pre-Installation Requirements

• Wiring for units must be provided by the installer and must comply with all national and local

electrical codes.

• Rooftop curb mounted units must be sealed tightly to the curb. Use proper sealants and roof

to curb sealing techniques to prevent water and air leakage.

Note: Preparation of the roof curb or pier mount and roof openings should be completed prior to

lifting the unit to the roof.

Roof Curb Installation Checklist

It is recommended that the curb be installed directly on the support members and fastened to the

supports using tack welds or other equivalent methods. Properly supported decking should be

installed inside the air handler section of the curb when this method is used. See Figure 1.

NOTICE

Roof Curb Structurally Sound

Check with curb manufacturer and job engineer to ensure the roof curb is structurally sufficient

to support the weight of the unit. The curb should be checked to ensure it is level and square.

Curb bowing, buckling, or sagging can lead to unit assembly and operation problems up to

complete failure.
