COOK Duct Blower - Manual

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.
Failure to follow these instructions could result in
death or serious injury.
