1. These values have been accessed using a model of sound propagation from a point source into the hemispheric\free field. The dBA val-
ues provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan manufacture has no
way of knowing the details of each system. This constitutes and expectation to any specification or guarantee requiring a dBA value or
sound data in any other form than sound power level ratings.

For units with VFD and electric or gas heat, the
speed of the indoor blower motor continues to be
controlled by duct static pressure via the VAV con-
trol board.
If there are VAV boxes present in the duct system,
the boxes must be driven to the full-open position
using a customer-supplied power source to assure
adequate airflow across electric heating elements or
gas heat exchanger tubes.
