Fan Installation - Fantech DBF110 Installation And Operation Manual

Fan Installation

Step 1. Selecting Fan Location
Fan must be mounted a minimum of 15 feet from the dryer outlet.
In order to perform recommended maintenance, fan location should allow
sufficient access for service. Refer to dimensional drawings shown above.
Step 2. Mount Bracket
Using the wood screws provided, attach the mounting bracket to a support
beam at the selected location. Bracket is provided with grommets in order
to isolate any vibration and prevent the transmission of sound through the
structure. Be careful not to overtighten. Fan mounting can be in any angle
(see ill. 2), however, vertical mounting is recommended to reduce
condensation buildup in the fan. If a horizontal installation is necessary and
condensation buildup may pose a problem, a ¼" hole drilled in the bottom
of the housing (along with an NPT insert [by others] and drain tubing) may
be installed to allow condensation to drain.
Step 3. Mount Fan
For proper operation, the switch diaphragm must be positioned vertically.
(Illustrations below show diaphragm position for horizontal, vertical 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.
Steps 2 & 3 may be reversed.
