least 90oC (194oF)
NOTE: Do not use the green screw and the ADA wire harness included in HAWSK3 ADA kit.
120 VAC POWER CABLE ENTERING THE SWITCH BOX
Install 2 included rocker switches at a convenient place for the user. Feed the switch box with 120 VAC house wiring and use two 14/2 cable to wire it to the range hood (see diagram below).
NOTES:
-
Allow enough length of both 14/2 cables to perform the RED, the BLUE and the BLACK wire connections in the top right side of right blower scroll.
-
Use appropriate wire nuts for all connections.
-
Insert both 14/2 cable coming from switches in the hood through an UL approved wire clamp. With a short ground wire (not provided), connect all ground wires together as shown below. Connect the other end of the short ground wire to the GREEN ground screw.
-
Connect WHITE wire from no. 2 14/2 cable to WHITE wire from range hood wiring.
-
Run BLACK wire from no. 2 14/2 cable along with BLACK and WHITE wires from no. 1 14/2 cable to top right side of right blower scroll. See next page for continuation.
