Receiving and Inspection

Immediately upon receipt of an SRSH fan, carefully

inspect the fan and accessories for damage and shortage.

• Turn the wheel by hand to ensure it turns freely and

does not bind.

• Check dampers (if included) for free operation of all

moving parts.

• Record on the Delivery Receipt any visible sign of dam-

age.

Handling

Lift the fan by the shipping carton or fan skirt only. 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.

INSTALLATION, OPERATION AND MAINTENANCE MAN-

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

If the fan was delivered with the motor unmounted, see the

maintenance section for belt and pulley installation.

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 or inside the duct

work. Ensure the damper will open freely for the correct

direction of the airflow.

b. Secure to curb at the damper shelf.

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

wiring.

d. Operate the dampers manually to ensure the blades

move freely.

e. Install fan over curb while aligning the conduit location

with the conduit hole in the 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.
