Handling
Lift propeller wall fans by attachment to the power
assembly.
NOTICE! Never lift by the shaft, motor or housing.
Storage
If the fan is stored for any length of time prior to installa-
tion, coat the shaft with grease or a rust preventative com-
pound. Store it in its original shipping crate and protect it
from dust, debris and the weather.
Rotate the wheel several revolutions every three to five
days to keep a coating of grease on all internal bearing
parts.
Installation
Fans mounted to a wall require a different wall opening
size than fans mounted in wall collars or wall housings. For
specific dimensions, refer to the submittal drawing for the
specific fan type.
Motor Installation
To prevent damage to the fan during shipping, motors 5
HP and larger, and extremely heavy motors (cast iron or
severe duty) are shipped loose and must be field mounted
by bolting the motor on the motor mounting plate in the
existing slots.
The motor should be mounted in order that the motor
plate is between the fan shaft and the motor shaft.
1.
Remove the motor plate mounting bolts and motor plate.
2.
Remove the motor mounting bolts from the motor plate.
3.
Mount the motor to the motor plate aligning the appropriate
holes.
4.
Place the motor plate on the power assembly and reinstall
the mounting bolts.
Belt and Pulley Installation
Belt tension is determined by the sound of the belts when
the fan is first started. The belts will produce a loud squeal,
which dissipates after the fan is operating at full capacity.
If belt tension is too tight or too loose, lost efficiency and
damage can occur.
Do not change the pulley pitch diameter to change ten-
sion. The change will result in a different fan speed.
1.
Loosen the motor plate adjustment nuts on motor base and
move motor plate in order that the belts can easily slip into
the grooves on the pulleys. Never pry, roll, or force the belts
over the rim of the pulley.
2.
Adjust the motor plate until proper tension is reached. For
proper tension, a deflection of approximately 1/4" per foot of
center distance should be obtained by firmly pressing the
belt. See Figure 3.
3.
Lock the motor plate adjustment nuts in place.
4.
Ensure pulleys are properly aligned. See next section.
Pulley Alignment
Pulley alignment is adjusted by loosening the motor pulley
setscrew and by moving the motor pulley on the motor shaft.

The drawing below indicates where to measure the al-
lowable gap for the drive alignment tolerance. All contact
points (indicated by WXYZ) are to have
a gap less than the tolerance shown in
the table. When the pulleys are not the
same width, the allowable gap must
be adjusted by half of the difference in
width. Figure 3 illustrates using a car-
penter's square to adjust the position of
the motor pulley until the belt is parallel
to the longer leg of the square.
Installation
Insert the fan into the wall opening and secure with lag
screws, anchor bolts, or other suitable fasteners.
Always mount belt drive wall fans in order that the motor
base is below the fan shaft.
Wiring
NOTICE! Correctly label the circuit on the main
power box and always identify a closed switch to
promote safety (i.e., red tape over a closed switch).
All wiring should be in accordance with local ordinances
and the National Electrical Code, NFPA 70. Ensure the
power supply (voltage, frequency, and current carrying ca-
pacity of wires) is in accordance with the motor nameplate.
Follow the wiring diagram in the disconnect switch and
the wiring diagram provided with the motor.
Leave enough slack in the wiring to allow for motor move-
ment when adjusting belt tension. Some fractional motors
have to be removed in order to make the connection with
the terminal box at the end of the motor.
Wall Fans
1. Extend wires to the fan.
2. Prevent excess wire from entering the shaft and pro-
peller area by restraining the excess wire to a point
outside the base.
Wall Fans with Wire Guard
1. Remove end panel from the wire guard to gain access
to the motor.
2. Extend wires through a side panel of the wire guard to
gain access to the motor.
3. Prevent excess wire from entering the shaft and pro-
peller area by restraining the excess wire to a point
outside the base.
