Fan Installation - Fantech DBF 110 Manual De Instalación Y Mantenimiento

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.
Step 4. Installing Grommet and tubing
First, drill a 5/16 inch to 3/8 inch diameter hole in the duct wall.
Carefully insert the grommet into the hole. (Drilling a metal duct may
produce burrs. Be careful not to be cut or pricked by the burrs or the
duct.) Next, force one end of the tubing over the nipple on the control.
Make a mark a distance of 1/2 inch from the other end of the tubing.
Slide this end of the tubing through the center of the grommet up to the
mark as illustrated.
