Installing Fan and Bracket
1. Before selecting mounting location for fan, consider the following:
a) Mounting the fan as far as possible from the intake point will
assure quiet operation. A minimum of 8' of insulated flexible duct
is recommended between exhaust grille and fan.
b) Place fan where it can be easily accessed for service.
2. Attach the mounting bracket to a
support beam with wood screws
provided. Fan can be mounted at
any point along the duct and at any
angle.

horizontally mounting, either wrap
insulation around the fan or drill a

housing. Add NPT insert and drain
tube (purchased separately) for
drainage of condensation.
3. Attach fan to the mounting bracket with the sheet metal screws
provided. Position wiring box for easy access. Rubber vibration
isolation grommets are included with bracket to prevent
transmission of sound through the structure. Do not overtighten.
Screws are self tapping but for best results pilot holes no larger than
3

" are recommended.

4. Connect duct to inlet and outlet of fan using plastic ties or duct tape
(purchased separately). When using insulated flexible duct, the inner
vinyl core should be clamped or taped to the inlet and outlet and the
vapor barrier surrounding the insulation should be duct taped to the
fan housing. Fantech recommends insulated flexible duct for all
bathroom exhaust applications.
Please Note: Steps 2 & 3 may be reversed.
Flexible Duct Installation Hints
Fantech strongly recommends the use of flexible insulated duct where
ducting passes through unconditioned space or where noise is a factor.
Check local code requirements before installing. Failure to use insulated
flexible duct could result in excessive condensation buildup within the
duct, and undesirable sound levels within the room.
A minimum of 8' of insulated flexible duct is recommended between
the fan and any inlet grille. Duct should be stretched as tight and straight
as possible. Failure to do so could result in dramatic loss of system
performance. Connect flex duct to the fan with plastic zip ties or duct tape.
Connections should be airtight as possible for maximize performance.
Electrical Connection
Remove the screws securing the terminal box cover located on the
1.
side of the fan. All fan motor connections are pre-wired to an
electrical terminal strip. A
will be needed to secure the wiring through the knockout on the side
of the terminal box.
2. Bring incoming electrical service through the romex connector and the
fan knockout. Be sure to place the connector nut over the wiring coming
into the terminal box. There are two open ports on the terminal strip.
Using a small regular screwdriver, tighten the neutral (white) wire of the
incoming supply under the open terminal strip port labeled "N". Tighten
the line (black) wire of the incoming supply under the open terminal strip
port labeled "L". Since the fan motor is isolated within a plastic housing,
grounding is not necessary.
3. Secure the romex connector. Secure the incoming supply with the
romex connector. Replace the fan terminal box cover. All fan motor
and capacitor connections have been pre-wired from the factory. No
additional fan wiring is necessary.

Troubleshooting
If fan fails to operate, please check the following:
1. Consult wiring diagrams (above) to ensure proper connection.
2. Check motor lead wiring, capacitor leads and incoming supply leads
to insure definite contact.
3. If possible, use a meter to test for continuity across the fan motor
leads. In order to do this, the capacitor must be disconnected (do
not test the capacitor - it will not meter continuity). If motor leads
show continuity, consult factory for a replacement capacitor.
Maintenance Instructions
Since fan bearings are sealed and provided with an internal lubricating
material, no additional lubrication is necessary.
