PLAN THE INSTALLATION
The unit can
be installed
anywhere
between ceiling
joists using
mounting
brackets
provided.
*
Install in a fl at
ceiling only.
Typical Installation
Ducting has a strong effect on the air fl ow, noise and energy use of
the fan. Use the shortest, straighest duct routing possible for best
performance, and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce energy loss
and inhibit mold growth. Fans installed with existing ducts may not
achieve their rated airfl ow. The unit will operate most quietly and
effi ciently when located where the shortest possible duct run and
minimum number of elbows will be needed.
Plan to supply the unit with proper line voltage and appropriate power cable.
