WARNINGS

DO NOT CONNECT POWER SUPPLY UNTIL FAN IS
COMPLETELY INSTALLED. MAKE SURE ELECTRICAL
SERVICE TO THE FAN IS LOCKED IN "OFF" POSITION.

1. TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS - OBSERVE
THE FOLLOWING:

a. Use this unit only in the manner intended by

the manufacturer. If you have questions,
contact the factory.

b. Before servicing or cleaning, switch power off

at service panel and lock service panel to
prevent fan from being switched on
accidentally. When the service disconnecting
means cannot be locked, securely fasten a
prominent warning device, such as a tag, to
the service panel.

Installation Guidelines

Fan and Switch Mounting

The DBF110 is to be mounted a minimum of 5 linear (not equivalent) feet
from the dryer outlet. A secondary lint trap (DBLT 4W) is recommended
if the fan is installed between 5 and 15 linear (not equivalent) feet from
the dryer outlet in applications, where excessive dryer lint generation is
likely or to increase the time interval between routine maintenance of the
Dryer Booster Fan (See illustration to left). An NB mounting bracket
attached to a rafter or joist should be used to stabilize the fan. Although
not recommended, a vertical rigid duct may support the fan if the duct is
securely stabilized. (Consult local codes prior to supporting the fan in the
duct alone.) Duct work should be attached to the inlet and outlet of the
fan by means of FC vibration isolation clamps (not included) or duct tape.
The duct connection should be properly sealed to prevent leakage and
loss of fan performance. Flex duct connections between the dryer duct
connection and exhaust duct should be stretched as smooth as possible.

Calculating Duct Run

To calculate the length of your planned duct run, measure from the dryer
to external venting point in roof or wall. For each bend or elbow add 5-7
feet to your total duct run calculations. The DBF110 can be used on runs
up to 108 feet.

Pressure Sensor Switch Operation

Fantech’s DBF110 is equipped with Fantech's Patented DB10 pressure
switch. The DB10 is a positive pressure sensing switch which
recognizes dryer operation and activates the booster fan from an
independent electrical circuit. This eliminates connections through the
dryer circuit which may void the manufacturers’ warranty as well as
manual systems which require the attention of the operator or costly
current/temperature sensing systems.

The electricity to the booster fan is connected in series through a
normally open terminal on the switch. A pressure tap is connected to a
fitting on the side of the switch. When the dryer begins operation,
positive pressure in the duct causes the switch diaphragm to expand,
closing the circuit to the booster fan. An integral delay-on-break timer in
the switch will cycle the fan on for intervals of 10 minutes. This will con­tinue until the dryer has stopped and the timer delay period has lapsed.
Drying cycles, the booster fan, the delay timer and the pressure switch
are not adversely affected by the starting/stopping intervals.

Sensitivity Adjustment Instruction

a. Disconnect power to the booster fan.
b. Looking from the inlet (dryer side), the switch should be at the

12-o-clock position.

c. Remove the 2 mounting screws holding the switch to the fan.
d. Rotate the switch to the 10-o-clock position for less sensitivity or

2-o-clock position for more sensitivity then secure it there, you may
have to adjust (bend) the bracket to fit. Secure the switch with the
2 screws previously removed.

e. Apply power to the fan and check for operation.

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.
