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.
For Hanging
Installations:
Use manufacturer’s

choose a location
with the shortest
possible duct run
and minimum
number of elbows.
Do not mount near
cooking equipment, as
shown in Fig. 1.
2. Attach adjustable
mounting brackets
to fan, but leave the
screws loose until
proper height is
determined, shown
in Fig. 2. Cut hole to
dimensions shown
in table 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.
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.

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.
Washable aluminum mesh filters specifically designed
for these fans are available, please consult your
representative for more information.
General Maintenance Suggestions
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.
