Cabinet Fans

INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

Handling

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

the shaft, motor, or housing.

Storage

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

tion, store it in its original shipping crate and protect it from

dust, debris and the weather.

Installation

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 mounting slots.

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 name-

plate. Refer to the Wiring Diagrams, on page 2.

Lock off all power sources before unit is wired to power

source.

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.

damage.

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.
