In-Line Duct Fans
are designed to boost dry conditioned (heated or cooled) indoor airflow in ducts of forced air systems with temperatures between 40°F (4°C) and 140°F (60°C). Suncourt accepts no
TM
responsibility for use of this product in other applications.
EXPOSURE TO AIRFLOW TEMPERATURES EXCEEDING 140°F (60°C) WILL PERMANENTLY DAMAGE THE FAN AND VOID THE WARRANTY.
ELECTRICAL SAFETY INSTRUCTIONS
WARNING – To Reduce the Risk Of Fire, Electrical Shock, or Injury to Persons, Observe the Following:
Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction and accessibility.
Your In-Line Duct Fan
must be connected to a 110/120 Volt AC, 60Hz fuse or circuit breaker protected power source only in a manner approved by all applicable codes. Never connect your In-Line Duct Fan
TM
a 240 Volt AC blower motor or other 240 Volt AC system. Never connect your In-Line Duct Fan
taps on the furnace blower; always use isolation relays.
The power source must be protected by a fuse or circuit breaker rated at a minimum of 15 amperes.
You may also supply power to your In-Line Duct Fan
For In-Line Duct Fans
without power cord attached, all connections to the power supply must be made inside the electrical box provided with the unit. Use power supply conductors and wire nuts of appropriate
TM
size and type. Attach a wire nut to any unused lead in a 2-speed In-Line Duct Fan
For In-Line Duct Fans
with power cord attached, the cord can be plugged in to any standard (NEMA 5-15) 3-prong outlet. The outlet supplying power to the cord must include a ground terminal properly
TM
connected to a ground source. The power cord should be secured to a location where it is not subject to damage, abrasion, or temperatures exceeding 140°F (60°C).
GENERAL INSTALLATION NOTES
For maximum performance and minimum noise, the best location to install your In-Line Duct Fan
To prevent air leaks, use a good quality aluminum foil duct tape to seal the seams in the ductwork after installing the In-Line Duct Fan
By utilizing tapered reducers, you may install larger diameter duct fans in smaller diameter ducts to achieve greater boosted airflow.
Always leave your In-Line Duct Fan
accessible for maintenance, cleaning, or repair.

ACCESSORY INFO
Ductstat
Temperature Sensitive Switch
®
The In-Line Duct Fan
can be controlled by our Ductstat
TM
to operate the fan only when conditioned air is sensed inside the boosted duct. Please visit www.suncourt.com for more info on the Ductstat
Standard Variable Speed Control, model VS100
The speed of your non-corded In-Line Duct Fan
adjust the fan speed without damaging the motor. The speed control mounts inside a standard 2x4 electrical box and includes a cover plate and mounting hardware.
WARNING – NEVER USE A RHEOSTAT OR LIGHT DIMMER SWITCH TO CONROL YOUR FAN SPEED. A SOLID-STATE SPEED CONTROLLER MUST BE USED TO AVOID DAMAGE TO THE MOTOR.

MODEL: DB100C
1. Locate the place in the duct where you wish to install the In-Line Duct Fan™.
2. Tape the enclosed template to the duct with the arrow pointing in the direction of the airflow. Cut out the required opening by first drilling a pilot hole and cutting along the dashed
line using a jig saw or tin snips.
3. Place the Inductor® In-Line Duct Fan™ in the opening, making sure that the fan blade can turn freely. Align the arrow on the unit in the direction of airflow.
4a. Connect the spring through the middle hole provided in the base plate, stretch the spring over the duct and through the middle hole on the other side of the loose plate. Bend the
ends of the spring over to secure, providing a snug installation.
4b. Secure the In-Line Duct Fan™ in position with the supplied #6 sheet metal screws using the provided holes in the base plate of the unit.
5. Finish the installation by covering the seams in the duct with a good quality aluminum foil duct tape.
MODELS: DB200C, DB204C
1. Locate the place in the duct where you wish to install the In-Line Duct Fan™. Align arrow label on unit in direction of airflow.
FLEXIBLE DUCT
2a. Simply cut the flexible duct and slide the In-Line Duct Fan™ in place by slipping the cut flexible duct ends over the crimped ends on the In-Line Duct Fan™,
making sure the unit is well supported.
Complete the installation by securing the In-Line Duct Fan™ to the flexible duct with a good quality aluminum foil duct tape or nylon cable ties.
METAL DUCT
2b. Remove a section of the existing ductwork and slide the In-Line Duct Fan™ in place by slipping the duct ends over the crimped ends of the unit. Complete the
installation by securing the In-Line Duct Fan™ to the metal duct with the supplied #6 sheet metal screws spaced evenly around the circumference on each end of
the unit.
3. Finish the installation by covering the seams in the duct with a good quality aluminum foil duct tape.
