Installing Fan and Bracket
1. Before selecting mounting location for fan, consider the following:
a) For optimized performance the 6x6x6 wye connector and the inline
fan should be located near the end of the duct system. Additionally,
choose a wall or roof cap that is less restrictive to air flow.
b) Mounting the fan as far as possible from the intake point will
ensure quiet operation. A minimum of 8' of insulated flexible duct
is recommended between exhaust grille and fan.
c) Place fan where it can be easily accessed for service.
2. Attach the mounting bracket to a
support beam with wood screws
provided. Rubber vibration isola-
tion grommets are included with
bracket to prevent transmission of
sound through the structure. Do
not overtighten. Fan can be
mounted at any point along the
duct and at any angle. Vertical mounting is recommended to reduce
condensation in the fan. For horizontally mounting, either wrap
insulation around the fan or drill a

drainage of condensation.
3. Attach fan to the mounting
bracket with the sheet metal
screws provided. Position wiring
box for easy access. Screws are
self tapping but for best results
pilot holes no larger than
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.

A minimum of 8' of insulated flexible duct is recommended between

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 to maximize performance.

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 three open ports on the terminal strip.
Using a small regular screwdriver, secure the ground wire (bare or
green) to the open port with the incoming green/yellow wire. 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".
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.
