Step 2. Mount Bracket
Using the wood screws provided, attach the mounting bracket to a sup-
port beam at the selected location. Bracket is provided with grommets
i
n order to isolate any vibration and prevent the transmission of sound
through the structure. Be careful not to overtighten. Fan mounting can
b
e in any angle (see ill. 2), however, vertical mounting is recommended
to reduce condensation buildup in the fan. If a horizontal installation is
n
ecessary and condensation buildup may pose a problem, a

rilled in the bottom of the housing (along with an NPT insert [by oth-

S
tep 3. Mount Fan
For proper operation, the switch diaphragm must be positioned verti-
c
ally. (Illustrations below show diaphragm position for horizontal, verti-
cal and ducts installed at an angle.) Wiring box should be positioned for
easy access. Attach fan to the mounting bracket with the self tapping
screws provided. Care should be taken not to strip the plastic housing.
Although screw pilot holes are not required,
³|₃₂" (or smaller) pilot holes
are recommended.
NOTE: Steps 2 & 3 may be reversed.
