Installation
1. Before installing the blower, unpack the unit and check
for physical damage to the motor and blower assembly.
To do so, reach in through the intake collar and spin
the fan blades slowly. They should spin freely and qui-
etly without vibration.
2. Remove the blower’s top cover by removing the screws
around the edge that hold it in place.
3. Apply sealant between the blower and the mounting
surface where the flange around the edge of the blower
will rest.
4. With assistance, pick up the blower assembly and cen-
ter it on the mounting surface inserting the intake collar
into the cutout.
5. While holding the blower in place, fasten it to the
mounting surface with eight (8) mounting screws. The
mounting holes are located inside the blower assembly
chassis near the sides.
6. Install the duct work according to the installation
instructions for the hood or downdraft vent. Support the
duct weight as necessary to ensure properly sealed
joints.
