Storage

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

tion, completely fill the bearings with grease or moisture-

inhibiting oil (refer to Lubricants on page 5). 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.

Outdoor Storage

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 com-

pound.

• Wrap bearings for weather protection.

• Cover the entire fan to prevent the accumulation of dirt

and moisture in the fan.

• Periodically rotate the wheel and operate the dampers (if

supplied).

• Periodically inspect the fan to prevent damaging condi-

tions.

Installation

Most motors are shipped mounted on the fans with belts

and drives installed. However, extremely heavy motors and

drives are shipped separately and some motors are shipped

separately due to height limitations. These motors and

drives will require field installation. Please refer to page 4.

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 foun-

dation’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

CPL

This publication contains the installation, operation and

maintenance instructions for standard units of the CPL

Centrifugal Plenum Fans.

Carefully read this publication and any supple-

mental documents prior to any installation or

maintenance procedure.

Loren Cook catalog CPL provides additional information

describing the equipment, fan performance, available

accessories, and specification data.

For additional safety information, refer to AMCA publica-

tion 410-96, Safety Practices for Users and Installers of

Industrial and Commercial Fans.

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 dam-

age 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 on the housing.

NOTICE! Never lift by the shaft, wheel, or motor.

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.

CPL Centrifugal Plenum Fans INSTALLATION, OPERATION, AND MAINTENANCE MANUAL This publication contains the installation, operation and maintenance instructions for standard units of the CPL Centrifugal Plenum Fans. Carefully read this publication and any supplemental documents prior to any installation or maintenance procedure. Loren Cook catalog CPL provides additional information describing the equipment, fan performance, available accessories, and specification data.
PAGE 2
Duct Installation 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 fan and its motor. Efficient fan performance relies on proper installation. If the fan has an open inlet (no duct work), be sure it is placed one fan wheel diameter away from walls and bulkheads. Refer to figure 2.

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. Wiring Line reactors may be required to reduce over-voltage spikes in the motors. The motor manufacturer should be consulted for recommended line impedence and usage of line reactors or filters, if the lead length between the VFD and the motor exceeds 10 feet (3m).
PAGE 4
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). c. Lock the motor plate adjustment bolts in place d. Ensure pulleys are properly aligned.

• Bearings should be inspected as recommended in the Conditions Chart. • Inspect variable inlet vanes for freedom of operation and excessive wear. The vane position should agree with the position of the control arm. As the variable inlet vanes close, the entering air should spin in the same direction as the wheel. • Inspect isolation base for freedom of movement. • Inspect springs and rubber isolators for deterioration and replace as needed. • Inspect for cleanliness. Clean exterior surfaces only.

Lubrication - Motor Bearings Max Class Speeds of PLC Motors are provided with prelubricated bearings. Any lubrication instructions shown on the motor nameplate supersede instructions below. Motor bearings without provisions for relubrication will operate up to 10 years under normal conditions with no maintenance.

Troubleshooting p. Repeat the process for opposite bearing. q. Adjust the belt tension. r. Test run and retighten all setscrews and bolts. Trim balance as necessary (.0785 in/sec max.). After 24 hours of operation, retighten the setscrews to the appropriate torque. This assures full locking of the inner race to the shaft. Make sure the socket key or driver is in good condition with no rounded corners.
