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
TM
(4°C) and 140°F (60°C). Suncourt® accepts no 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
TM
applicable codes. Never connect your In-Line Duct Fan
to a variable-speed (ECM) furnace blower. For a two-speed In-Line Duct Fan
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
Separately).
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
TM
power supply conductors and wire nuts of appropriate size and type. Attach a wire nut to any unused lead in a 2-speed In-Line Duct Fan
wiring must always include a ground wire properly terminated at the fan (green wire).
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
TM
cord must include a ground terminal properly 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

Standard Variable Speed Control, model VS100
The speed of your non-corded In-Line Duct FanTM (models DB412E, DB414E, DB416E) can be controlled with our model VS100 Variable Speed Control.
This speed control utilizes solid-state circuitry to safely 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.
