Planning Your Fan Location
As with any exhaust system, your exhaust fan should be located a minimum
of 6 feet horizontally and 8 feet vertically from any fresh air intakes to
prevent re-entrainment of exhaust air streams. For example HVAC systems,
heat recovery systems, and windows would all be considered fresh air
intakes.
When planning your fan placement keep in mind that you will need to
be able to run your duct work from the exterior fan to the bathroom inlet.
Considering access for the duct run before hand will make installation easier.
Installating Exterior Wall Fan
1. Once you have chosen the location where you wish to mount the fan, cut
a 4 3 / 8 " diameter hole in the exterior of the wall. Prepare a piece of rigid
duct (purchase separately) approximately 2" longer than the wall thickness.
This will be used as a collar extension placed through the wall.
2. Take off the fan discharge cover by removing the four screws. Center the
fan in the hole that was cut into the wall. Mark the locations of the mounting
holes and electrical knockout. Drill a hole for the electrical that is 1 / 8 " larger
than the conduit being used. A 1" electrical service opening is provided on
the fan backplate .
NOTE: When mounting the fan to a masonry wall, drill 7 / 32 " holes for the
four anchors and mounting screws (provided). Anchors should be flush with
the edge of the holes. For mounting to wood surfaces use wood screws
(purchased separately).
3. Bring your electrical supply through the wall. Attach the fan collar to the
extension collar using duct tape. Be sure this connection is as airtight as
possible to prevent leakage. Apply polyurethane caulk to the exterior of fan
housing backplate, leaving bottom uncaulked for drainage. This will ensure an
airtight/waterproof connection between the fan and wall.
NOTE: If installing on lapped siding it may be necessary to use a mounting
frame made from 1x1 board to insure a flush fit.
4. Mount the fan to the wall. Replace the
discharge cover. Connect your ducting to the
extension collar using plastic ties or duct tape
(purchased separately).
FINAL INSTALLATION NOTE: If fan location is
not protected by an eve, a standard flashing
should be installed. Seal against the wall and
upper edge of the fan discharge cover to
prevent rain water from entering fan housing.
Fantech recommends insulated flexible duct for
all bathroom exhaust applications.
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
1. Remove the screws securing the terminal box cover located on the fan
motor mounting bracket. All fan motor and capacitor connections are pre-
wired to an electrical terminal strip. A 3/8" 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 electrical service opening. 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" to the ground connection on the terminal block.
3. Secure the romex connector. Secure the incoming supply with the romex
connector. Place the capacitor back into the terminal box. 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.
