The ducting from this fan to the outside of the building has a
strong effect on the air flow, noise, and energy use of the fan.
Use the shortest, straightest duct routing possible for the best
performance, and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce energy
loss and inhibit mold growth. Fans installed with exisiting ducts
may not achieve their rated flow.
To ensure quiet operation of ENERGY STAR
®
qualified inline and remote fans, each fan shall be
installed using sound attenuation techniques appropriate for the installation. For bathroom and general
ventilation applications, at least 8 feet of insulated flexible duct shall be installed between the exhaust or
supply grille(s) and the fan. For remote ventilation applications, where metal duct is generally required
by code, a metal sound attenuator shall be installed between the hood and the fan.
5. ELECTRICAL CONNECTION
All TD-SILENT series fans operate from a standard 120V, 60Hz AC electrical supply. All wiring must
be carried out in accordance with National Electrical Code and all applicable state and local buildings
codes.
Electrical connections should be made in accordance with the following diagram:
See Figure (3)
3. ENVIRONMENT
The TD-SILENT series of fans are suitable for operation within indoor environments only.
The TD-SILENT units are suitable for the exhaust or supply of both conditioned and un-
conditioned airstreams within the temperature ranges. Size 125XS and 200S are suitable
for working airstreams up to 104 deg F (40C), whereas sizes 150S is suitable for working airstreams
up to 140 deg F (60C).
4. MOUNTING
The TD-SILENT series can be mounted in any orientation, horizontal or vertical, and is suitable
for numerous types of applications.
See Figure (1)
. Illustration of some typical applications. If the
installation is made to rigid or flexible ducting, then we would recommend the correct diameter
ducting is used to couple to the fan flanges. If it is necessary to bend the duct at the discharge of the
fan, then the bend radius should be as large as possible.
All models include a robust mounting bracket which enables easy and quick installation of the fan.

Installation Diagrams For TD-MIXVENT Duct Fans.
Seal penetrations, duct, and fan with duct fast clamps, duct tape, or other similar material (available
through your local distributor) to create an air-tight path from the ventilated space to the building exterior.
Use flexible or rigid insulated duct and wrap the fan with insulation where allowed by code in order to
reduce: heard noise, building heat loss/gain, and condensation.
