Warnings
DO NOT CONNECT POWER SUPPLY until unit is completely installed. Make sure electrical service to the fan and light is locked in
“OFF” position.
WARNING! TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS – OBSERVE THE FOLLOWING:
a. Use this unit only in the manner intended by the manufacturer. If you have any questions, contact your manufacturer's representative.
b. CAUTION: Before installation, servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power from being
switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as tag, to the service panel.
c. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards. This unit is only for use in non-
fire-rated installations.
d. When cutting or drilling into wall and ceiling, do not damage electrical wiring and other hidden utilities.
e. NEVER place a switch where it can be reached from a tub or shower.
f. If this unit is installed over a tub or shower, it must be connected to a GFCI (Ground Fault Circuit Interrupter) – protected branch circuit.
g. The combustion airflow needed for safe operation of fuel burning equipment may be affected by this unit’s operation. Follow the heating equipment manufac-
turer’s guidelines and safety standards such as those published by the National Fire Protection association (NFPA), the American Society of Heating,
Refrigeration, and Air Conditioning Engineers (ASHRAE) and the local code authorities.
h. Exhaust fans must always be vented to the outdoors.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Exterior Wall Fan Installation
1. When selecting the fan mounting location, the following criteria should be considered:
a) With any exhaust system, the fan should be located a minimum of 6 feet
horizontally and 8 feet vertically from any fresh air intakes for HVAC systems, heat recovery systems, etc. to prevent re-entrainment of exhaust air
streams. Windows that are frequently opened during moderate seasons
may also be considered fresh air intakes.
b) Although system noise at the point of exhaust will be virtually silent, win-
dows and other structural openings may be sources for noise entry during
fan operation. Proximity to windows and openings should be considered.
Select the location on the exterior wall where the fan is to be mounted. Make a hole
through the wall that is 1/2” larger than the diameter of the fan duct connection collar. A short piece of rigid duct (not included) approximately 2” longer than the wall
thickness is recommended for use as an extension through the wall.
2. Remove the four screws securing the white fan discharge cover and remove the
cover. Place the fan against the wall, as centered as possible on the wall opening, then mark the location of the four backplate mounting holes and the electrical knockout. Drill a hole for the electrical service that is 1/8” larger than the
size of conduit to be used. A 1” diameter electrical service opening is provided
on the fan backplate (see dimensional drawing on Page 1). When mounting the
fan on a masonry wall, drill 7/32” holes for the four anchors and mounting
screws (provided). Tap the anchors flush into the holes. When mounting the fan
on a wood surface, wood screws should be used.
If the fan is to be mounted on a wall surface which is Lapped Siding, a mounting frame
made from 1x1 board may be necessary for a flush fit (see I-2).
3. Before mounting the fan, bring the electrical supply through the wall. Attach the
extension collar to the fan duct connection collar. The connection should be as
air tight as possible to prevent leakage from the wall cavity. Apply a generous
amount of polyurethane caulk to the exterior side of the fan housing backplate
(except the bottom so that water that leaked in can drain back out). This will
ensure an airtight/waterproof connection between the fan and the wall surface.
If a mounting frame is used in conjunction with lapped siding, be certain to apply
a generous amount of caulk between the frame and the wall as well as the fan
backplate and the frame. Mount the fan to the wall.
Be certain to make an airtight seal around all interior wall penetrations before attaching duct work.
FINAL INSTALLATION NOTE: If the fan is being mounted in a location where it is not
protected by an eve, it is highly recommended that a standard flashing be installed
and sealed against the wall and upper edge of the fan discharge cover to prevent rain
water running down the wall surface from entering the fan housing (see I-1).

Electrical Connection
1. Remove the screws securing the terminal box cover plate located on the
side of the fan. All fan motor connections are pre-wired to an electrical ter-
minal strip. A ³|₈" romex type cable restraint connector will be needed to
secure the wiring through the knockout provided 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".
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 (at right) 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.

Flexible Duct Installation Hints
Flexible insulated duct is strongly recommended where allowed by local code for
bathroom exhaust applications, where ducting passes through unconditioned space
or where noise is a factor. Failure to use insulation could result in excessive condensation buildup within the duct, and undesirable sound levels within the room.
For the quietest possible installations, Fantech recommends a minimum of 8' of
insulated flexible duct between any inlet grille and fan. When using flexible type
duct work, duct should be stretched as tight and straight as possible. Failure to do
so could result in dramatic loss of system performance. Flexible duct should be
connected to the fan with plastic zip ties or duct tape. All connections should be
as airtight as possible to maximize system performance
