Typical Installation

DANGER
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power
source can result in fire, shock or serious injury.
DANGER
Pour écarter les risques d'incendie, de choc électrique
ou de blessure grave, veiller à toujours débrancher,
verrouiller et étiqueter la source de courant avant
l'installation ou l'entretien.
Move fan to the desired location and determine the
method by which the fan is to be mounted as shown
in Figures 1-5 shown on page 3. Optional wall mount
housings (Figure 1) and wall mount collars (Figure 2)
provide a convenient means of mounting sidewall
propeller fans while maintaining the proper distance
between propeller and damper.
Attach the fan by inserting a suitable fastener through
each of the prepunched mounting holes in the fan panel.
Care should be taken not to bend or distort the fan
panel or drive components during installation.
Support Braces
Wall Housing sizes 42 and larger with heavy motors
and all Filtered Supply Wall Housings need additional
bracing.

Pre-Start-Up Checks

Check all fasteners and setscrews for tightness. This is
especially important for bearing setscrews.
The propeller should rotate freely and not rub on the
fan panel venturi. Rotation direction of the propeller
should be checked by momentarily turning the unit on.
Propeller blade should
cup and throw the air
when rotating in the
correct rotation as
shown in the figure.
Rotation should be
in the same direction
as the rotation decal
affixed to the unit.

For 3-phase installations, fan rotation can be reversed
by simply interchanging any two of the three electrical
leads. For single-phase installations follow the wiring
diagram located on the motor.
For belt drive fans, the adjustable motor pulley is preset
at the factory for the specified fan RPM. Fan speed can
be increased by closing or decreased by opening the
adjustable pulley. Two or three groove variable pitch
pulleys must be adjusted an equal number of turns
open. Any increase in fan speed represents a substantial
increase in horsepower required from the motor. Always
check motor load amperage and compare to nameplate
rating when changing fan speed.
