and speed controls. Capacities range from 25 to 1,600
cfm (42 to 2,718 m
Licensed for Sound and Air Performance.

ENERGY STAR® Certified models include:
XCR-A, 50, 70, 90, 200, 250, 290 and 410;
XCR-B, 50, 70, 80 and 90.

To reduce the risk of fire, electric shock, or injury to persons,
observe the following:

• Suitable for use with solid state speed controls.

• Use this unit only in the manner intended by the manufacturer. If
you have questions, contact the manufacturer.

• Before servicing or cleaning unit, switch power off at service panel
and lock service disconnecting means to prevent power from being
switched on accidentally. When the service disconnecting means
cannot be locked, securely fasten a prominent warning device,
such as a tag, to the service panel.

• Installation work and electrical wiring must be done by qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction.

• Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment
to prevent back drafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE) and the local code authorities.

• When cutting or drilling into wall or ceiling, do not damage
electrical wiring or other hidden utilities.

• Acceptable for use over a bathtub or shower when installed
in a GFCI protected branch circuit. (Up through size SP-A390)

• Never place a switch where it can be reached from a tub or
shower.

• Ducted fans must always be vented to the outdoors.

• These fans are not recommended for cooking exhaust
applications. They are designed primarily for low temperature,
clean air applications only. The diagram shows the minimum
distance these fans should be placed in relation to cooking
equipment.

• Fan/Light
insulated to a value greater than R40.

• For general ventilating use only. Do not use to exhaust hazardous
or explosive materials and vapors.

Remove the two screws holding the power assembly
in and pull power assembly out. Rotate power
assembly 180 degrees and put back into fan. Use
the same screws to reattach power assembly to fan
housing. Flip fan over and remove the four screws
holding the discharge duct and damper assembly.
Exchange the assembly with plate mounted on top of
fan, as shown in these illustrations.

Ceiling Radiation Damper (CRD)

A

A

If fan is to be used in a fire resistive membrane
ceiling, a ceiling radiation damper must be used.

If the ceiling radiation damper is already mounted to
the fan from the factory, proceed to Install the Fan.

To mount the ceiling radiation damper to fan, make sure
grille attachment tabs are facing down. Then place the inlet
part of the fan into the ceiling radiation damper collar, and
use self-tapping sheet metal screws (by others) to screw
through the damper collar and into the fan housing. If the
fan/light combination is being used, make sure ceiling

radiation damper has
an electrical plug in it.
The electrical plug must
be inserted into the fan.
Make sure the electrical
wire will not interfere with
damper operation as
shown in figure below.
