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 the service panel and lock service disconnecting means to prevent power from being switched on accidentally. Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-ratedconstruction 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 the 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 an 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 screwslocations. Pull the blower chamber out of the hood assembly andset it aside with its retaining screws and nuts.
• Remove and set aside the 4 front screws retaining the bent plate to the hood.
• Fold back the bent plate to access the control panel connections.

CAUTION: Use standard switches that are rated 120 VAC, 15 A. Only use wires suitable for at least 90oC (194oF). 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.
• Allow enough length of 14/3 cable to perform the RED wire connection in the hood nose.

1. 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 GREE ground screw. Use an appropriate wire nut to connect the othe 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.
2. Connect BLACK wire from house wiring to WHITE wire from 14/3 cable using an appropriate wire nut.
3. Connect BLACK wire from 14/3 cable to BLACK wire from range hood wiring using an appropriate wire nut.
4. Connect WHITE wire from house wiring to WHITE wire range hood wiring using an appropriate wire nut.
5. 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.

1. Insert the 14/3 cable in the hood through an UL approved wireclamp. Connect ground wire to the GREEN ground screw.
2. Connect WHITE wire from 14/3 cable to WHITE wire from range hood wiring using an appropriate wire nut.
3. Connect BLACK wire from 14/3 cable to BLACK wire from range hood wiring using an appropriate wire nut.
4. Run RED wire from 14/3 cable through bend plate wiring opening for hood control connection. See next page for RED wire connection.

RED WIRE CONNECTION

NOTE: The light switch in the range hood rocker switch controls differs from one model to another; some light switches have 2 terminals while others have 3 terminals. The illustrations below apply to both light switch models.

• Cut the BLACK wire that is connected to motor switch and light switch.
• Cap off the BLACK wire connected to the light switch terminal. Connect the RED wire from 14/3 cable to the BLACK wire from the motor switch, using an appropriat wire nut.
• Once all the connections are done, finalize the installation by reversing steps 6 to1 on first page.

NOTE: Be careful while reinstalling the wiring cover to the hood.

CAUTION: Ensure both tabs on inner top of hood are engaged in their corresponding slots in wiring cover. Also, take care no to pinch wires while reinstalling wiring cover.
