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.
