In order to perform recommended maintenance, sufficient
access to the fan should be allowed at its location. Fan should
be mounted a minimum of 15' away from the dryer outlet, up to
a maximum of 90'. To calculate the length of the duct, measure
the length from the dryer outlet to the termination point; add 5'
of duct for each bend or elbow.
Note: An auxiliary lint trap (LT100) may be used to minimize lint
build up in the system.

Attach mounting brackets to the fan
housing as shown in Figure 1a or Figure
1b. Attach the fan to a support beam at
selected location. Vertical mounting is
recommended to reduce condensation
build-up in the fan, however, the fan may
be mounted in any position. The terminal
box (wiring box) should be positioned for
easy access. The airflow direction arrow
located on the junction box cover shows
the direction of the airflow, which cannot
be reversed.
SSTTEEPP33..CCOONNNNEECCTTDDUUCCTT
Connect the duct to the inlet and outlet
ends of the fan housing (by means of
mounting clamps or duct tape). The duct
connection should be properly sealed to
prevent air leakage and loss of fan per-
formance. Rigid duct is recommended
and should be installed as straight as
possible. If using flex duct, it should be
stretched as smooth as possible.

DDVVKK110000BBfans are not explosion proof and should not be used
when a potentially explosive situation exists. Do not use where
temperatures will exceed 140oF/60oC.
1. Ensure that the electrical service to the fan is locked in the
“OFF” position. Do not re-establish power supply until fan
and activation device are completely installed.
2. DDVVKK110000BBfans are not suitable for outdoor use.
3. This unit has rotating parts! Safety precautions must be
exercised during installation, operation and maintenance.
Turn centrifugal impeller by hand to make sure it rotates
freely.
4.
CCAAUUTTIIOONN::
For general ventilation use only. Do not use to
exhaust hazardous or explosive materials and vapors.
5.
WWAARRNNIINNGG::
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 manu-
facturer. If you have questions, contact the factory.
b) A qualified person(s) must perform installation work and
electrical wiring in accordance with all applicable codes
and standards, including fire-rated construction.
c) The combustion airflow needed for safe operation of fuel
burning equipment may be affected by this unit’s opera-
tion. Follow the heating equipment manufacturer’s
guidelines and safety standards as published by the
National Fire Protection Association (NFPA), the
American Society of Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE), and local code
authorities.
d) When cutting or drilling into walls or ceilings, take care
not to damage electrical wires or other hidden utilities.
e) Ducted fans must always be vented to the outdoors when
used to exhaust moist/humid air.
6.
WWAARRNNIINNGG::
Check voltage at the fan to see that it corresponds
to the motor nameplate.
Note:
The DVK100B-T kit cannot be used in systems where the duct length is 25' or less. The DVK100B-T is suitable to overcome an equivalent of 90' of 4" rigid duct.

If fan fails to start, please follow the procedure listed below:
1. Check the incoming supply for proper voltage.
2. Ensure that the electrical service to the fan is locked in the
“OFF” position.
3. Consult wiring diagram to ensure proper connection.
4. Use a meter to test the continutity across the fan motor leads.
5. If the motor leads show continuity, rewire the fan and timer.
6. Turn on the electrical supply and restart.
7. Check to be certain that fan starts.
8. If fan fails to start:
a) Ensure that the electrical service to the fan is locked in
the “OFF” position.
b) Remove the timer from the circuit.
c) Connect the incoming power supply directly to the fan motor.
d) Turn on power to fan.
9. If fan fails to start, please contact technical support @
1-800-779-4021.

CCAAUUTTIIOONN::
1. Before servicing or cleaning, ensure that the electrical
service to the fan is locked in the “OFF” position.
2. Fan bearings are sealed. No additional lubrication is necessary.
3. Periodic inspection, based upon usage, should be performed
to ensure that the fan impeller is not obstructed. The fan
should be inspected a minimum of every six (6) months.
4. Excessive fan noise or vibration may indicate an obstructed
impeller.
5. To inspect and clean impeller:
a) Ensure that the electrical service to the fan is locked in
the “OFF” position.
b) Remove the duct from the fan inlet and remove any
obstruction from the impeller.
c) Reconnect the duct to the fan.
d) Turn power supply on.

The CCTT--1100000-1 hour spring wound interval timer is
easily installed in a standard electrical box. This
spring wound timer will automatically turn the fan off
after a preset period. For automatic operation, turn
timer clockwise to desired drying time. Timer will
turn “OFF” at the end of preset timed period.

Ensure that the electrical service to the fan is locked in the
“OFF” position. Wiring must be done in accordance with all
applicable codes and standards. The unit must be properly
grounded. Ensure the supply voltage corresponds to the volt-
age listed on the name plate.
