Storage

If the fan is stored for any length of time prior to

installation, completely fill the bearings with grease or

moisture-inhibiting oil (refer to Lubricants on page 6).

Rotate the wheel several revolutions every three to five

days to keep a coating of grease on all internal bearing

parts.

Store the fan in its original crate and protect it from dust,

debris and the weather.

To maintain good working condition of the fan when it is

stored outdoors, follow the additional instructions below.

• Coat the shaft with grease or a rust preventative

compound.

• Wrap bearings for weather protection.

• Cover the inlet and outlet to prevent the accumulation of

dirt and moisture in the housing.

• Periodically rotate the wheel and operate dampers (if

supplied).

• Periodically inspect the unit to prevent damaging

conditions.

Installation

Motor Installation

Most motors are shipped mounted on the fans with belts

and drives installed. However, extremely heavy motors and

drives are shipped separately. These motors and drives will

require field installation.

Foundation

This fan requires a strong, level foundation of reinforced

poured concrete. A correctly designed concrete foundation

provides the best means for mounting floor units. The

foundation’s size is determined by fan size and

arrangement, motor size and position, and the specific

location of the installation.

INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

FCP

This publication contains the installation, operation and

maintenance instructions for standard units of the FCP

Fiberglass Blowers.

Carefully read this publication and any

supplemental documents prior to any

installation or maintenance procedure.

Loren Cook Company’s Fiberglass Catalog 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 Installers

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 FAX at (417)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.

Handling

Lift the fan by the base or lifting eyes. NOTICE! Never lift

by the shaft, motor, or housing.

Rotating Parts & Electrical Shock Hazard:

Disconnect electric power before working on unit.

Follow proper lockout / tagout procedures to ensure

the unit cannot be energized while being installed or

serviced.

A disconnect switch should be placed 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.

Grounding is required. All field-installed wiring must

be completed by qualified personnel. All field-

installed wiring must comply with National Electric

Code (NFPA 70) and all applicable local codes.

Failure to follow these instructions could result in

death or serious injury.

FCP Fiberglass Blowers INSTALLATION, OPERATION, AND MAINTENANCE MANUAL This publication contains the installation, operation and maintenance instructions for standard units of the FCP Fiberglass Blowers. Carefully read this publication and any supplemental documents prior to any installation or maintenance procedure. Loren Cook Company’s Fiberglass Catalog provides additional information describing the equipment, fan performance, available accessories, and specification data.

Use the following guidelines to calculate foundation size: • The overall dimensions of the foundation should extend at least 6 inches beyond the outline of the fan and its motor. • The weight of the foundation should be 2 to 3 times the weight of the unit and its motor. Isolation NOTICE! Although a certain amount of vibration is inherent in operating centrifugal fans, extreme vibration is a serious problem that may cause structural and mechanical failure.
PAGE 3
Wheel-to-Inlet Clearance The correct wheel-to-inlet clearance is critical to proper fan performance. This clearance should be verified before initial start-up since rough handling during shipment could cause a shift in fan components. Refer to wheel/inlet drawing for correct overlap. Adjust the overlap by loosening the wheel hub and moving the wheel along the shaft to obtain the correct value.
PAGE 4
Pulley Alignment 9. Restore power to the fan. Pulley alignment is adjusted by loosening the motor pulley setscrew and by moving the motor pulley on the motor shaft. Figure 4 indicates where to measure the allowable 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 Figure 5 the pulleys are not the same width, the allowable gap must be adjusted by half of the difference in width (As shown in A & B of Figure 4).
PAGE 5
Maintenance Establish a schedule for inspecting all parts of the fan. The frequency of inspection depends on the operating conditions and location of the fan. Inspect fans exhausting corrosive or contaminated air within the first month of operation. Fans exhausting contaminated air (airborne abrasives) should be inspected every three months. Regular inspections are recommended for fans exhausting non-contaminated air. It is recommended the following inspection be conducted twice per year.

Lubrication - Fan Bearings Greasable fan bearings are lubricated through a grease fitting on the bearing. For motors with provisions for relubrication, follow intervals of the following table.

number 3RAR9 or equal. 10. Reapply beeswax to protect the set screw heads. 11. Install the new shaft by sliding the bearings to the desired location using the measurement record earlier and loosely mounting the bearing support. Bearing bolts and bearing set screws should be loose enough to allow shaft position later. Please note the wheel to inlet clear matches as close as possible the diagram on page 3 12.
