INSTALLATION(joist mounting)
Fig.3
STEP.1:PLAN THE INSTALLATIONS
The unit operates most quietly and efficientlywhen located
where the shortest possible duct run and minimum number of
elbows are needed.(Fig.3)
Plan to supply the unit with proper line voltage and appropriate
power cable.
NOTE
THE FOLLOWING INSTALLATION ILLUSTRATIONS SHOW 2X6 JOISTS. IF YOU HAVE A
TRUSS OR "I"- JOIST INSTALLATION, MOUNT THE VENTILATOR TO THE ADDITIONAL
FRAMING IN THE SAME MANNER.
STEP.2:INSTALL THE HOUSING
1. Choose the location for your fan in the ceiling. For best possible performance, use the
shortest possible duct run and a minimum number of elbows.
2. Position mounting brackets against joist so that bottom edge of housing will be flush
with finished ceiling.
Additional positioning feature for 1/2", 3/4", 1", &1-1/4" thick ceiling material:
Holes in corners of housing are labeled with various ceiling material
thicknesses. Positionhousing so bottom edge of joist is visible through
a matched set of holes. The housing is now in the proper position for
that ceiling material thickness.(Fig.4)
