7.2 Air Handler Mounting to Roof Curb
After the curb has been installed, the air handler may be placed on the curb. See Page 16, Figure 6. After the
air handler is in place, the installer must fasten the air handler to the curb. This is accomplished by drilling
holes down through the floor of the air handler and into the curb. At least three #12 sheet metal screws
(supplied by others) equally spaced on each side must be used to attach the air handler to the curb. After the
curb has been installed, the air handler may be placed on the curb. The installer is responsible for tying the
air handler to the curb per all applicable codes.
FIGURE 6: Curb Mounting
There must be a 1/8" (.3 cm) x 2" (5.1 cm) neoprene closed cell, adhesive-back gasket (supplied by others)
between the top of the curb and the base surface of the air handler to prevent moisture from leaking into the
building from either driving rains or melting snow.
