Low Profile Centrifugal Exhaust Fans

INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

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

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.

Damper Installation

If your fan is supplied with dampers, follow the directions

below. If your fan does not include dampers, proceed to

Belt and Pulley Installation.

a. Place the damper inside the curb. Ensure the damper

will open freely for the correct direction of the airflow.

b. Secure to curb at the damper shelf.

c. Drill a hole in the curb shelf for conduit needed for

motor wiring.

d. Operate the dampers manually to ensure the baldes

move freely.

e. Install ventilator over curb.

The attachment of roof mounted fans to the roof curb

as well as the attachment of roof curbs to the building

structure must exceed the structural requirements

based on the environmental loading derived from the

applicable building code for the site. The local code

official may require variations from the recognized

code based on local data. The licensed engineer of

record will be responsible for prescribing the correct

attachment based on construction materials, code

requirements and environmental effects specific to

the installation.

Failure to follow these instructions could result in

death or serious injury.

moving parts.

damage.

Handling

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.
