Receiving and Inspection
Carefully inspect the fan and accessories for any damage and
shortage immediately upon receipt of the fan.
• Turn the wheel by hand to ensure it turns freely and does not
bind.
• Inspect dampers for free operation of all moving parts.
• Record on the Delivery Receipt any visible sign of damage.
Handling
Lift the fan by the outside housing (box) and support bracket.
Never lift by the shaft or motor.
Storage
If the fan is stored for any length of time prior to installation, store
it in its original shipping crate and protect it from dust, debris and
the weather.
To maintain good working condition of a CV when it is stored
outdoors, or on a construction site, follow the additional steps
below:
• Cover the inlet and outlet, and belt tunnel opening to prevent
the accumulation of dirt and moisture in the housing.
• Periodically rotate the wheel and operate dampers (if supplied)
to keep a coating of grease on all internal bearing parts.
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.
UCV Fan Installation
The fan support (roof curb) should provide a level surface for
installation. If the roof is pitched more than 1/2:12, a sloped curb
must be used to correct for the incline. If the unit is installed on a
non-level surface, the damper door pivot should be positioned
perpendicular to the peak of the roof.
Place fan over roof opening. Secure the fan with lag screws,
anchor bolts, or other suitable fasteners.
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.

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.
