Installation, Operation, and Maintenance Manual
Installation
Move fan to desired location and fasten securely through mounting holes in base. Shims may be necessary depending upon
roofing material thickness. The diagram below shows dimensions for Model XRUD.
Access to the motor compartment is accomplished by removing the screws designated "R" in the drawing below. The cover
can then be removed and placed on a flat surface in an area protected from strong winds that could blow it off the roof.
The voltage rating of the motor must be checked for compatibility to supply voltage prior to final electrical connection. For
NFPA - restaurant applications, the electrical supply must enter the motor compartment through the breather tube. For other
non-flammable applications, the electrical supply can be routed through the conduit chase between the curb cap and the
bottom of the motor compartment. Consult local code authorities for your specific requirements.
IMPORTANT: UL/cUL 762 Installations are for Restaurant Applications.
A, B, and C motor RPMs are only approved for this installation. All must include the suffix "G".
A drain trough is provided on all XRUD fans for one point drainage of residue. Some means of collection of this residue must
be provided by either placing a container directly under the trough or by utilizing an adapter to direct the residue to another
location.

Pre-Starting Checks
Check all fasteners for
tightness. The wheel
should rotate freely and
be aligned as shown at
right. Wheel position
is preset and the unit
tested at the factory.
However, movement may
occur during shipment,
and realignment
may be necessary. Centering (height alignment) may be
accomplished by loosening the
set screws in the wheel and
moving the wheel to desired
position.
Please read and save these instructions for future reference. Read carefully before attempting to assemble, install, operate
or maintain the unit. Failure to comply with instruction could result in personal injury and/or property damage!
Upon receiving unit, check for any damage that may have occurred during transit and report it immediately to the shipper.
CORRECT
Also check to see that all accessory items are accounted for.

Dimension "A" is the inside dimension of the curb cap.
The roof curb should be 1-1/2" less than the curb cap to allow for
roofing and flashing.
*May vary depending on motor size.

Wheel Rotation

Direction of rotation is very critical. Improper
rotation will result in loss of performance,
excessive horsepower and possible motor
burnout. Check rotation by energizing the
H
unit only momentarily. The rotation should
be as shown in the
diagram at right and
should be in the
same direction as
the rotation decals
affixed to the unit.
