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. Vertical mounting is recommended to reduce condensation in
the fan. For horizontally mounting, either wrap insulation around the
fan or drill a

⁄

" hole in the bottom of the housing. Add NPT insert

and drain tube (purchased separately) for drainage of condensation.

3. For PB Series fans, if bracket is used to mount fan, refer to illustration 1.

If suspending fan with hanger straps, refer to illustration 2.

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.

Installing Fan and Bracket

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.

Wiring Diagrams

Multiple Location Switching Wiring Diagram

Electrical Connection

Remove the screws securing the terminal box cover located on the side
of the fan. All fan motor connections are pre-wired to an electrical
terminal strip. A

⁄

" romex type cable restraint connector 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 three 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". Tighten the ground (green) wire of the incoming supply
under the open terminal strip port labeled with the Ground symbol. If the
terminal strip is not labeled, follow the wiring diagram found on the inside
of the electrical cover.

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.
