ALWAYS disconnect power prior to working on fan.
Centrifugal Filtered Supply Fans
INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
This publication contains the installation, operation and maintenance instructions for standard
units of the ASP/KSP-Centrifugal Filtered Supply
Fans.
Carefully read this publication prior to any installation or maintenance procedure.
Loren Cook catalog, ASP/ASP-T and KSP, provides
additional information describing the equipment, fan
performance, available accessories, and specification
data.
For additional safety information, refer to AMCA publication 410-96, Safety Practices for Users and Install-
ers of Industrial and Commercial Fans.
All of the publications listed above can be obtained
from Loren Cook Company by phoning 417/869-6474,
extension 166; by F AX at 41 7/832-9431 ; or by e- mail at
info@lorencook.com.
For information on special equipment, contact Loren
Cook Company Customer Service Department at 417/
869-6474.
Receiving and Inspection
Carefully inspect the fan and accessories for any
damage and shortage immediately upon receipt of the
fan.
• Turn the wheel by hand to ensure it turns freely and
does not bind.
• Inspect dampers (if supplied) for free operation of
all moving parts.
• Record on the Delivery Receipt any visible sign of
damage.
Installation
Motor Installation
To prevent damage to the fan du ring 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 e xisting mo unting
slots.
KSP Assembly
NFPA 96 installation guidelines for KSP fans are shown in
figure 1 and 2 on page 2.
a. Remove the top cap (item 3) from the fan.
b. Remove the intake hood (item 2) and the filter(s) (item 1)
from the inside of the fan.
c. Replace the topcap.
d. Slide the intake hood over the flange on the fan and
secure with the nine screws provided.
e. Remove the two thumb screws and the filter retainer.
f. Slide the filter(s) down between the angles inside the
intake hood and the flange on the front of the hood.
g. Replace the filter retainer and secure with the two thumb
screws.
h. Caulk the top of the intake hood where the hood meets
the fan. Use an appropriate caulk for exterior use.
Handling
Lift the fan by the base or lifting eye s. Never lift by the
shaft, motor, or housing.
Storage
If the fan is stored for any length of time prior to
installation, store the fan in its original crate and protect
it from dust, debris and the weather.

Personal Safety
Disconnect switches are recommended. Place the
disconnect switch near the fan in order that the
power can be swiftly cut off in case of an
emergency, and in order that maintenance
personnel are provided complete control of the
power source.

Leave enough slack in the wiring to allow for motor
movement 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. To
remove motor, remove bolts securing motor base to power
assembly. Do not remove motor mounting bolts.
Follow the wiring diagram in the disconnect switch
and the wiring diagram provided with the motor. 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).
Do not allow the fan to run in the wrong direction.
This will overheat the motor and cause serious damage. For 3-phase motors, if the fan is running in the
wrong direction, check the control switch. It is possible to interchange two leads at this location so that the
fan is operating in the correct direction.
Wiring Installation
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
capacity of wires) is in accordance with the motor nameplate.
Lock off all power sources before unit is wired to
power source.
Belt and Pulley Installation
Belt tension is determined by the sound the belts make
when the fan is first started. Belts will produce a loud
squeal which dissipates after the fan is operating at full
capacity. If the belt tension is too tight or too loose, lost efficiency and possible damage can occur.
