Install In-line Blower System
NOTE: The blower motor housing can be mounted using 4 holes
from either the inlet side or the outlet side of the blower.
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" (4.8 mm) 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.
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 1¹⁄
4
" (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.
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.
Make Electrical Connections for In-
Line Blower Motor System
Electrical Connection Inside In-line Blower System
1. Disconnect power.
2. Connect the wires from the wiring conduit to the wires from
the motor electrical plug cable inside the in-line blower
housing terminal box.
3. Use UL listed wire connectors and connect the black wires
(C) together.
