Ceiling Exhaust and Inline Fans
PN 461342
Installation, Operation and Maintenance Manual
Prepare the Fan
1. If power assembly (motor, wheel, and scroll) is not
installed in housing, insert the electrical plug into fan
socket, then slide scroll end of power assembly into
fan housing. Attach by using two sheet metal screws
provided, as shown in figure 1.
2. Remove either top or side wiring knockout,
depending on wiring direction, by bending it back and
forth to break tabs, as shown in figure 2.
3. Check duct work to see if the fan’s discharge needs
to be rotated from horizontal to vertical discharge, as
shown in figure 3. To rotate from horizontal to
vertical discharge, 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 figure 4.
4. 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 next step. 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 the self-tapping sheet metal
screws provided to screw through the damper collar and into the
fan housing, as shown in figure 5. If the fan/light combination is
being used, make sure ceiling radiation damper has a 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 6.

WARNING !
To reduce the risk of fire, electric shock, or injury to
persons, observe the following:
• If a speed controller is used, this fan should only be
used with fan speed control, manufactured by KB
Electronics, Inc.
• 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.
• The combustion airflow needed for safe operation of
fuel burning equipment may be affected by this
unit's operation. 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.
• This unit is suitable for use directly over a tub or
shower with a GFI branch circuit wiring. (Up through
size SP-A390)
• Ducted fans must always be vented to the outdoors.
• For general ventilating use only. Do not use to
exhaust hazardous or explosive materials and
vapors.
• 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.

Install the Fan
1. For best performance, choose a location with the shortest possible duct run
and minimum number of elbows. Do not mount near cooking equipment, as
shown in figure 7.
2. Attach adjustable mounting brackets to fan, but leave the screws loose until
proper height is determined, as shown in figure 8. Cut hole to dimensions
shown in Table A:
2a. 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, as shown in figure 10.
2b. For hanging installations, use Greenheck’s optional vibration isolator kit Part Number
VI Kit. Using the fan’s standard adjustable mounting brackets and 10 by 32 threaded
rod - by others, hang unit as shown in figure 11.
3. Installation of ductwork is critical to the performance of the fan as shown in figure 12.
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.
Note: If round duct is to be used, Model RDC (Round Duct Connector) can be purchased
from Greenheck that bolts in place of the standard square duct connector.
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 and wire nuts. 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 as shown in figure 13. Then wire unit to the
correct installation type, as shown in figure 13a, 13b, and 13c.

Installation Recommendations
Attach the Grille
Other Installation Considerations:
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, as shown in figure 14a
and 14b.
4. If lighted grille is being used, install light
bulb(s) into light socket(s). For incandescent
lights, use maximum 100 watt bulb – not
included. For fluorescent lights, use only Greenheck’s Part Number
382854, provided, 13 watt flicker resistant light bulbs. For replacement
bulbs please contact Greenheck at phone number 715-359-6171.
5. If lighted grille is being used, snap lens into place, by pushing on the outside
edges of lens, as shown in figure 14b. To remove lens, use small screw
driver and pry on one side of lens.
6. Turn on power and check fan and light operation.
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.
Greenheck offers washable aluminum mesh filters
specifically designed for these fans. Please consult
SP/CSP catalog for more information.

Warranty
Greenheck warrants this equipment to be free from defects in material and workmanship for a period of three years from
the purchase date. Any units or parts which prove to be defective during the warranty period will be replaced at our
option when returned to our factory, transportation prepaid.
Greenheck will not be responsible for any installation or removal costs.
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. (See Filters). 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.
