Mount Main Housing to Structure
When mounting the Main Blower Housing, the (4)
lag bolts must be attached to joists or studs, or
other structural members.
When mounting the main
blower housing between fl oor joists or walls studs,
it is necessary to space the blower housing off the
fl oor or wall using a minimum 2x4 wood spacer. The
wood spacers should be properly secured to the joists
or studs. DO NOT secure the wood spacers to the
sub-fl oor or wall materials.
Make the required electrical connections according
to the attached wiring diagram.
When mounting the main blower housing, be sure
to fully engage the inlet collar of the blower with the
round duct inlet from the downdraft ventilation unit.
Secure the outlet to the exhaust duct.
All duct connections should be sealed with duct tape
and secured with screws.
Connect the Romex cable from the downdraft
ventilation unit to the main blower housing.
DO NOT mount the main blower housing directly to
sub-fl ooring or wall materials, this will not support
the remote blower housing correctly.
When mounting the unit, do not warp or bend
the housing, or mount in such a manner that the
connected ductwork causes the housing to fl ex.
Before making any electrical connections, verify
that the blower wheel spins freely.
