STEP 6:

Using a flat blade screwdriver, loosen the screw for the left "NI" (POWER INPUT)

terminal _ inside the electrical access hole r_. rt is the fourth one down from the top
on the left side of the terminal block.

Remove the bJack and white wires [] from the terminal block. Separate the two wires

from each other.

Using a fiat blade screwdriver, pry off the clip _ that connects lifting arm i_l from
the motor assembly [] to the pin on the bottom of the plenum D (the plenum is the

portion of the vent that raises up when activated). Remove the lifting arm from the pin
on the plenum. Keep the clip for later use.

STEP 7:

Inside the motor assembly compartment II, disconnect the red and blue wires _ on

the motor wiring harness.

STEP 9:

Remove and retain the four (4)
screws O that hold the motor

assembly iq in place. Pull the motor
assembly out of the access hole.

As you pull the motor assembly out,

pull the black wire attached to it out
of the hole leading to the electrical

access panel.

Remove and retain the four (4)
screws on the back of the motor

assembly m and remove the motor
from the enclosure. Slide the wires

out of the hole on the side of the
enclosure as you remove it.

[_ WARNING: Failure to connect the wiring harnesses as instructed may result in an electric

shock or fire hazard.

STEP 12:

Using a permanent marker, cross
out the word "COM", on the labels

II_ on the black wire connected to

the motor. Relabel the labels "NC'.

STEP 13: Connect the ends of the black

wire to the "NC" (normally closed)

terminals ![_ on the two micro
switches located on the motor

base plate. The black wires are
interchangeable and may be

connected to either switch.

STEP 14:

Connect the red, the blue and one
of the yellow wires from the kit to

the micro switches as shown in the
picture. IMPORTANT: The end of

the wire with the black insulation is
the end that connects to the switch

terminal. The RED wire connects to
the "COM" terminal Ill on the

upper limit switch. The YELLOW

wire connects to the "NO" (normally

open) terminal m on the upper
limit switch. The BLUE wire

connects to the "COM" terminal

I_ on the lower limit switch. The

"NO" terminal _ on the lower limit
switch remains unconnected.

STEP 18:

STEP 19:

STEP 20:

Reinsert the motor assembly into
the raised vent and reattach it

using the existing screws. Insert
the motor assembly so that the

wires come out of the right side
I!_ of the motor enclosure as

you face the raised vent. Before
tightening into place, make sure

that the hole m on the end of the
lifting arm from the motor assembly
is placed over the top of the pin on

the bottom of the plenum I[_.
Reattach the lifting arm using the

existing retaining clip removed in
step 6.

Remove the red wire M (marked
"L") from the "L" terminal on the
relay it.It is located on the bottom
left, inside the electrical access

hole. Pull the red wire completely
out of the unit and discard.

STEP 21 :

Connect the remaining yellow wire

I_ from the kit to the same

terminal I[_ on the relay the red

wire was connected to in step 20

(the "L" terminal). IMPORTANT:
The end of the wire with the black

insulation is the side that connects
to the relay terminal. Slide the

other end of the wire through the
hole Im in the top right of the
electrical access panel, and into

the motor assembly compartment.

STEP 22: Slide the black wire n from the

motor assembly !1_ through the
hole m into the electrical access

panel as shown.

STEP 23:

STEP 24:

STEP 25:

Inside the electrical access panel,

twist together the un-insulated
ends _ of the black wire routed

from the motor assembly (see
step 22) and the white wire

disconnected from the "NI"
terminal in step 5.

Reconnect the black and white

wires to the left side of the "NI"

terminal i_1 inside the electrical
access panel.

Connect the wiring harness from
the motor to the wiring harness

from the electrical access panel.
Match the colors, red to red Ill,

blue to blue i[_, yellow to
yellow I_--_.IMPORTANT: Do not

loop the wires around the plenum

wiring harness Ill.
