Complete Preparation
1. Determine and make all necessary cuts for the vent system.
IMPORTANT: When cutting or drilling into the ceiling or wall,
do not damage electrical wiring or other hidden utilities.
2. Determine the location where the 1/2"(1.3 cm) wiring conduit
will be routed through the ceiling or wall between the in-line
blower and the range hood.
3. Drill a 1V4" (3.2 cm) hole at this location.
4. Locate the electrical terminal boxes in the in-line blower
housing and range hood (see "Complete Preparation" in the
"Prepare Location" section). Remove the terminal box covers
and set the covers and screws aside.

A. Mounting holes
1. Position the in-line blower motor housing in its mounting
location and mark the 4 mounting hole locations.
2. Drill 4 mounting pilot holes using a 3/16"(0.48 cm) drill bit.
3. Attach the in-line blower motor housing to the mounting
location with four 6 x 80 mm mounting screws and washers.
4. If it is removed, reinstall the blower motor assembly and
secure it with the screws previously removed.
5. If it is removed, reattach the motor electrical plug to the
connector on the blower motor assembly.

A. Electrical terminal box
B. Electrical knockout
5. Remove the electrical knockout from the in-line blower
housing and range hood (see "Complete Preparation" in the
"Prepare Location" section) to prepare for the installation of
the UL listed or CSA approved 1/2"(1.3 cm) wiring conduit and
conduit connector.
6. With the range hood mounted (see the "Install Range Hood"
section), run the 1/2"(1.3 cm) wiring conduit between the in-
line blower motor housing and the range hood. Pull enough
1/2"(1.3 cm) wiring conduit to allow for easy connection to the
terminal boxes in the in-line blower housing and range hood.
7. Run the six 18 AWG wires through the 1/2"(1.3 cm) wiring
conduit and conduit connectors and into the terminal boxes
on the in-line blower housing and range hood. Leave enough
wire length in each terminal box to make the wiring
connections.
8. Install the conduit connectors and conduit to the in-line
blower housing and range hood electrical terminal boxes.
9. Connect the vent system to the range hood and in-line blower
system and seal all joints with clamps.
