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 SP

Model CSP

Model SP 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 m3/hr) and 1 in. wg (248 Pa).
AMCA Licensed for Sound and Air Performance.

Model CSP is a direct drive inline exhaust fan designed
for clean air applications where low sound levels are
required. Capacities range from 70 to 3,800 cfm (119 to
6,456 m3/hr) and 1 in. wg (248 Pa). AMCA Licensed for
Air Performance.

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

WARNING!
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 combination not to be installed in a ceiling thermally
insulated to a value greater than R40.

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

Ceiling Radiation Damper (CRD)
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.

3. Installation of ductwork
is critical to the performance
of the fan, shown in Fig. 5.
Straight ductwork (1) or
ductwork that turns in
the same direction as the
wheel (2) is recommended.
Ductwork turning opposite
the wheel direction (3) will
cause turbulence and back
pressure resulting in poor
performance.

For Frame Construction:
Position unit between
joists. Position brackets
such that bottom
edge of housing will
be flush with finished
ceiling, and tighten the
adjustable mounting
brackets, shown in
Fig. 3.

NOTE
Model SP-A 50-90 are standard with a round duct.
Should Model SP-A 110-190 require a round duct,
Model RDC (Round Duct Connector) may be ordered
from Greenheck for ﬁeld installation.

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.

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

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. Greenheck has replacement 27W
GU24 bulbs call 1-800-355-5354 to order.

Squeeze

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

Flex Duct
Connections

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

speciﬁcally designed for these fans. Please consult our

General Maintenance Suggestions
Model SP/CSP 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.
