Unpacking
When receiving the unit, inspect carefully for any damage that may have occurred during transit.
Shipping damage claim must be filed with carrier.
General Safety Information
This unit should be assembled and installed by a qualified technician.
Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
Motor must be securely and adequately grounded. This can be accomplished by wiring with a grounded,
metal-clad raceway system by using a seperate ground wire connected to the motor's ground lug, or
other suitable means.
Protect power cable from coming in contact with sharp objects.
Do not kink power cable and never allow cable to come in contact with oil, grease, hot surfaces, or
chemicals.
Make certain that the power source conforms to requirements of your equipment.

7
Installation
Fans should be installed in an exterior wall located
where there will be no obstructions to the flow of
air into or out of the fan.
Once a location has been determined; an opening
should be made in the wall and framed to provide
enough clearance around the fan housing (SeeRough
Opening Chart page 12).
Framing must be able to support the weight of the
fan assembly.
Manual handling of the fans may result in serious
injury.Where appropriate, usemechanical methods
of lifting during installation. Where manual
handling is required enure you have adequate
assistance.
Position fan assembly in the framed opening.
Rigidly mount the housing side flanges to the
framework using mounting screws.
Remove electrical cover and connect power leads
to motor terminals using approved wiring method.
It is recommended to use the Watertight Connector
included with the motor if it is possible in your
application. (Motor terminal connection data is provided on
motornameplate).Use adequate size wirefor all branch
andfeeder runs.Whenspeed controlis used,follow
the installation procedures recommended by the
speed control manufacturer.
Re-install electrical cover.
Unit is now ready for operation.
Operation
Units may be operated using a switch, thermostat,
timer, or controller.
Followwiringand operation instructionsfurnished
with the control system selected.
When using speed controllers, follow the
operation procedures recommended by the
controller manufacturer.
Set thermostat setting to a desired temperature.
Fan will operate only when ambient temperature
is above the thermostat set temperature.
Some controllers have idle speed controls. Set
idle speed such that the blade RPM is within the
RPM range listed in the Performance Table.
Cleaning
It is advisable to clean blade and shutter at regular
intervals. This will remove any accumulated dirt,
whichwould causefan bladeto becomeunbalanced
and result in excessive vibration and poor
performance.
Lubrication
Motor is prelubricated at factory and will not
require any further lubrication.
Safety in Maintenance
Whilethe APPFan isdesignedto keepmaintenance
to a minimum, some repairs will be necessary in
thecourse ofthelife ofthe machine.Do not attempt
any repairs on the machine unless you are
competent to do so. Remember that the APP Fan
may in cases operate under automatic control and
willstart without warning.Neverattempt any work
on the APP Fan without first isolating the machine
from the mains power, and locking the isolator so
that only you can turn the power back on.

8
Motor overload protection should be provided
for each fan. A Circuit Breaker Switch or slow
blow motor type fuses must be used.
Note: a safety cut-off switch should be located
adjacent to each fan, such as "AP"#'s:
E100A1063 - 2.5 Amp
E100-A1064 - 5.0 Amp
E100-A1065 - 8.0 Amp
E100-A1066 - 15.0 Amp
Back-up Thermostats such as the TH-1, should
always be used in conjunction with your Control
System. These should be placed on a seperate
circuit to give your animals ventilation in the
event that your controller fails.
ElectricalWiring
All wiring should be installed in accordance with
National,State,and Local electrical codes.Fans used
to ventilate livestock buildings or other rooms where
continuous air movement is essential should be
connected to individual electrical circuits, with a
minimum of (2) circuits per room. We strongly
recommend the installation of supplementary natural
ventilation as well as a back-up thermostat and an
alarm system on at least one cooling stage.
For electrical connection requirements, refer to
diagram on motor nameplate and to information
enclosed with the "AVS" fan control to be used.

9

box

14
3. Attach motor mount leg (part # 11-0209) to the bearing plate
(part # 11-208), using two of the 3/8” bolts. Place two of the
3/8” bolts through the bearing plate and attach the motor mount
leg securely to it, using one washer per bolt. Slide the 1/4”eye
bolt through the hole on the motor mount leg, place the two
1/4” washers on the eye side of the bolt as shown below.
Tighten the eyebolt down securely, with its 1/4” nylock nut.
4. Attach spring tensioner plate part # 16-0034 to the motor
mount with the remaining 3/8” hardware, the slotted flat face of
the spring tensioner will face the U-shaped bottom of the bear-
ing.

15
5. Take the assembled motor mount and slide it into back end of
the housing with the “T” facing upwards. Line up the the holes
on the assembly to the predrilled holes in the housing. The as-
sembly should be 10” in from the housing edge. Cut a board to
approximately 29.5”, wedge this board into the space above the
“T” on the motor mount assembly. This will hold the assembly
in proper position to offset any settling the housing may have
experienced in shipment.

16
7. Get one 1” shaft part # 16-0005, two pillow block bearings part
# 16-0076, four 3/8” x 1-1/2”, four 3/8”-16 nuts part # S-8452,
and four 3/8” washers part # S-7021 from the hardware pack.
Slide the two pillow block bearings onto the shaft, have the
allen screw collars facing each other inwards. Insert bolt
through bearings and into the bearing mount plate, loosely fas-
ten.
6. Gather six 5/16” x 1” bolts part # S-7009, 5/16” washers part #
S-7005, and 5/16”-18 nuts part # S-8452 from the hardware
pack. Fasten two 5/16” bolts loosely to the “T” and the hous-
ing, one to each side. Remove board from its position.

17
8. Locate the prop, trantorque and the large driven pulley, part #s
13-0044, 13-0046, and 16-0007 respectively. Slide the prop
onto orifice end of the shaft and slightly tighten the trantorque.
Keep the shaft flush with the nut of the trantorque . Slide the
driver pulley onto the other end of the shaft, do not tighten.

18
9. Cut a spacer out of rigid substance (wood, metal, plastic,etc.) to
a distance of 3-3/8”. Loosen the trantorque until the prop can
be moved along the shaft. Place the spacer between the front
bearing and the backside hub of the prop. Slide the prop until
the hub is pressed against the spacer. Tighten trantorque down.
Making sure the bearing remains flush against the spacer,
tighten the front bearing down.

19
10. Cut a board to approximately 50”. Wedge this board into the
orifice of the fan. This will even out any settling that may have
occurred during shipment. Spin the prop until one blade points
directly down. Measure from the blade to the edge of the ori-
fice. Move the bottom leg of the motor mount assembly “T”
until this measurement reads 7.5”. Spin the bottom prop until
that same blade is facing straight up, and than measure again.
When the 7.5” measurement is established, secure the bottom
leg with the 5/16” bolts. Spin the prop and insure a consistent
gap between the tips of the blades and the wall of the orifice
housing.
