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.

Greenheck offers washable aluminum mesh filters
specifically designed for these fans. Please consult our
SP/CSP catalog for more information.

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.
