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.
