ADA LOW VOLTAGE WIRING INSTRUCTIONS FOR SINGLE BLOWER RANGE HOODS (PAGE 1 AND 2)
AND DOUBLE BLOWER RANGE HOODS (PAGE 3 TO 5)
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.
BRemove filters from the hood and set them aside.
CRemove 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.
DUnplug the blower connector from the main harness.
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 2).

EUsing 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.

THIS PROCEDURE APPLIES TO THE FOLLOWING
RANGE HOOD SERIES
KClose the control access panel and reinstall the blower by reversing
steps G 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
LOpen the provided connection box. Using long nose pliers, break away
2 cable entry notches on the lid (one per side).
HR0156
MPeel 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
OUsing 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
PPut 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.
RInstall 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
NUse 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.
QReinstall the hood wiring cover and attach it to the hood using its
retaining screw.

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,

ACCESS TO RANGE HOOD MAIN HARNESS
Due to their particular design, some range hood series have a different way to access to their main harness. These range hoods series are: EPLEC1,
NPLEC1 and SPE1 series and ALT4, EDJLD1 and EQLD1 series. For all other range hood series, go to page 4.
EPLEC1, NPLEC1 AND SPE1 SERIES
Remove both filters from the hood and set them aside.
Remove both side fillers by removing the 3 screws holding each one of them. Slide each one towards the center of the hood and tilt it up to remove it
completely. Set the fillers and screws aside.
