Installation, Operation and Maintenance Manual
Please read and save these instructions for future reference. Read carefully before attempting to assemble, install,
operate or maintain the product described. Protect yourself and others by observing all safety information. Failure
to comply with instructions could result in personal injury and/or property damage!
Model XCR
Model XCR is a direct drive ceiling
exhaust fan designed for clean
air applications where low sound
levels are required. Many options
and accessories are available such
as lights, motion detectors, ceiling radiation dampers
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.

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.

NOTE
Model XCR-A 50-90 are standard with a round duct.
Should Model XCR-A 110-190 require a round duct,
Model RDC (Round Duct Connector) may be ordered
from Manufacturer for field installation.
Wire the Fan
1. Remove wiring cover.
If fan/light combination
is being used, make
sure the fan plug is
connected to the fan
receptacle and the light
plug is connected to the
light receptacle, shown
in Fig. 6. Using proper
Fig. 6
wire connectors, wire
the fan as shown in Fig. 7a.
For wiring of light proceed to Fig. 7b.
2. Push all wiring into the unit’s cover and replace
wiring cover.

4. Slide ductwork over the fan’s discharge collar and
securely attach it with sheet metal screws.
Make sure the screws do not interfere with damper
operation. Check damper to make sure it opens freely.

Attach the Grille
1. If lighted grille is being used, plug wire into fan
socket.
If lighted grille and ceiling radiation damper are
being used, plug wire from lighted grille into ceiling
radiation damper socket. Do not plug wire directly
into the fan socket. Make sure the wire does not
interfere with the ceiling radiation damper operation.
2. Attach grille with two screws provided. Make sure
not to over tighten; over tightening will damage
grille.
3. Slide attachment screw covers over the attachment
screws, shown in Figure 8 and 9.
4. If lighted grille is being used, install light bulb(s) into
light socket(s). For incandescent lights, use maximum
100 watt bulb (by others). For fluorescent lights, use
27W GU24 bulbs. Manufacturer has replacement
27W GU24 bulbs call 1-800-355-5354 to order.
5. If lighted grille is being used, snap lens into place, by
pushing on the outside edges of lens, shown in Fig.9.
To remove lens, use small screw driver and pry on
one side of lens.
6. Turn on power and check fan and light operation.

Other Installation Considerations
Ductwork and Noise
Fiberglass ductboard is a better choice than metal
ductwork for reducing fan noise and is highly
recommended for low sound applications. Where metal
duct is used, sound transmission can be reduced with
flexible duct connections between the fan and the duct.
Sound and Location
The location of these fans must be taken into
consideration before installation. In critical sound
installations, insulated ductwork, flexible duct
connections or placing the fan in a remote section of
ductwork are solutions to meeting the required fan
sound levels.
Filters
The addition of an intake filter is highly recommended
for these fans, even in clean air environments excess
dirt can accumulate on wheels and motors causing
reduced performance and imbalance.
Filters, once installed, should be checked and cleaned
periodically to maintain performance.
Manufacturer offers washable aluminum mesh filters
specifically designed for these fans. Contact your
Accurex representative for more information.

General Maintenance Suggestions
Model XCR/XIR ceiling exhaust fans require very little maintenance. But since small problems over time left
unchecked could lead to loss of performance or early motor failure, we do recommend that the unit be inspected
periodically (once or twice a year).
The fan motor and wheel should be checked for dust and dirt accumulations. Dirt buildup can lead to loss of
performance and motor overheating. Cleaning can be accomplished by brushing off any dust that may have
accumulated. Even filtered units can accumulate build-up and should be checked when cleaning filters.
The motor should be checked for lubrication at this time. Lubricate only those motors which have an oil hole
provided. A few drops of all purpose oil (SAE 20) will be sufficient.
