ADA HIGH VOLTAGE WIRING INSTRUCTIONS FOR SINGLE BLOWER RANGE HOODS WITH
ROCKER SWITCH CONTROL
WARNING
For residential (domestic) installation only. Before proceeding, switch power off at service panel and lock service
disconnecting means to prevent power from being switched on accidentally. Installation work and electrical wiring
must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated
construction codes and standards. Also, it is recommended to wear safety glasses and gloves.
ACCESS TO RANGE HOOD CONTROL PANEL CONNECTIONS
NOTE: The illustrations in this procedure are generic; some hood details may slightly differ from the hood you have on hand but the
procedure itself applies to all single blower range hoods listed in this document (see page 3).
Remove filters from the hood and set them aside.
NOTE: Some models have only one filter.
Remove the wiring cover (shaded part in illustration below)
retaining screw. Slide the wiring cover out of the hood and set it
aside with its screw.

Unplug the blower connector from the main harness.
Using a 11/32'' socket, remove the 6 nuts retaining the blower
chamber to the hood assembly (2 nuts on inner back and 2 other
nuts per sides), then use a Phillips no. 2 screwdriver to remove
both front corner screws. See picture below for nuts and screws
locations. Pull the blower chamber out of the hood assembly and
set it aside with its retaining screws and nuts.

Use standard switches that are rated 120 VAC, 15 A. Only use wires suitable for at least 90C (194F). Ensure the
wires are reliably routed away from the halogen lights (if present).
To suit your needs, there are 2 ways to wire a 2-rocker switch control to these range hoods: 120 VAC power cable entering the range hood
or 120 VAC power cable entering the switch box.
120 VAC POWER CABLE ENTERING THE HOOD
Install a 2-rocker switch at a convenient place for the
user. Use a 14/3 cable to wire it to the range hood
(see diagram at right).
NOTE: The code requires both ends of the WHITE
wire insulation to be colored; use a permanent
marker.
NOTE: Allow enough length of 14/3 cable to perform the RED wire
connection in the hood nose.
Insert the 14/3 cable along with the 14/2 house wiring cable in the
hood through an UL approved wire clamp, suitable for 2 cables.
Add a GROUND wire and connect one of its end to the GREEN
ground screw. Use an appropriate wire nut to connect the other
end of the added GROUND wire with the ground wire coming
from the 14/3 cable and the ground wire coming from 14/2 house
wiring cable.
Connect BLACK wire from house wiring to WHITE wire from
14/3 cable using an appropriate wire nut.
Connect BLACK wire from 14/3 cable to BLACK wire from range
hood wiring using an appropriate wire nut.
Connect WHITE wire from house wiring to WHITE wire range
hood wiring using an appropriate wire nut.
Run RED wire from 14/3 cable through bend plate wiring opening
for hood control connection. See next page for RED wire
connection.

120 VAC POWER CABLE ENTERING THE SWITCH
Install a 2-rocker switch at a convenient place for the
user. Feed the switch box with 120 VAC house wiring
and use a 14/3 cable to wire it to the range hood (see
diagram at right).
NOTE: Allow enough length of 14/3 cable to perform the RED wire
connection in the hood nose.
Insert the 14/3 cable in the hood through an UL approved wire
clamp. Connect ground wire to the GREEN ground screw.
Connect WHITE wire from 14/3 cable to WHITE wire from range
hood wiring using an appropriate wire nut.
Connect BLACK wire from 14/3 cable to BLACK wire from range
hood wiring using an appropriate wire nut.
Run RED wire from 14/3 cable through bend plate wiring opening for
hood control connection. See next page for RED wire connection.
