THIS PROCEDURE APPLIES TO THE FOLLOWING

RANGE HOOD SERIES

K

 

Close the control access panel and reinstall the blower by reversing 

steps

 

to

 D 

on first page. Run the ADA cable section through the 

provided ferrite, making 2 loops. The ferrite must be as close as possible 
to the access panel.

HD0953

L

 

Open the provided connection box. Using long nose pliers, break away 
2 cable entry notches on the lid (one per side).

HR0156

M

 

Peel off the paper backing on back of connection box base and install 
the base at the location shown. Make sure that the surface is clean. This 
will place the connection box within the Wire Cover area near the blower 
connector. IMPORTANT NOTE: The base must be positioned flush to the 
notches (see circled area below).

HD0954

HE0278

O

 

Using  small UL approved wire nuts (suitable for 22 AWG wires), connect 
wires as follow: WHITE wire with WHITE wire, BLACK wire with BLACK 
wire and RED wire with RED wire.

HD0955

P

 

Put the wire nuts inside the connection box base, then snap the 
connection box lid on its base, ensuring the ADA cable runs through 
the open notches.

R

 

Install a momentary contact switch at a convenient place for the user. 
Connect the end without connector of the provided ADA cable to this 
switch as shown below:

HE0277

N

 

Use the remaining cable length of 15 ft. (from step 

H

) to connect to the 

remote ADA switch outside the hood (step 

R

). IMPORTANT: Leave a 

cable length of at least 12” that protrudes from the wall (at the same 
location of the 120 V house wiring). Run one end of the remaining 
section of the ADA cable though the range hood wire clamp, along with 
the power cable, giving enough length to make the connections inside 
the box. Tighten the wire clamp, then strip the end of the 3 wires from 
both ADA cable ends.

NOTE: The wire clamp must be suitable for 2 cables.

Reinstall the hood wiring cover and attach it to the hood using its
