AC - A 10
Electronic Air Cleaners
STEP 7
Remove the EAC-H 115VAC and EAC-N wires (white
and black) out of the junction box and pull them through
the grommet in the blower deck. Attach two supplied
¼” insulated female quick connect terminals by
stripping the wires and crimping the terminals onto
the wires. Attach these wires to the 115V terminals of
the 35VA transformer as shown in the diagram.
STEP 8
Remove the wiring harness supplied with the air
cleaner from the packaging. Attach a supplied 3/16”
insulated female quick connect terminal to the blue
wire and the green wire.
STEP 9
Attach the blue wire from the air cleaner wiring harness
to the open tab on the piggyback terminal supplied in
the BAYACCECOMM101. Attach piggyback terminal
to the 35VA transformer terminal “C” (Common).
STEP 10
Insert the 12” blue stripped wire under the terminal
strip screw marked “B/C” on the IFC control board. If
the application also includes an outdoor unit
(communicating or noncommunicating), the B/C
terminal will require 3 wires connected. For this
connection, rather than connecting the three wires to
the low voltage terminal strip on the furnace IFC, create
a pigtail using a short length of thermostat wire and a
wire nut (field supplied) to attach to the B/C terminal.
STEP 11
Connect the green wire from the air cleaner wiring
harness to the 24V terminal on the 35VA transformer
labeled “RD”. See diagram.
STEP 12
Insert the red stripped wire from the air cleaner wiring
harness under the IFC control board terminal screw
marked “R”. See diagram.
STEP 13
Attach the black stripped wire from the air cleaner
wiring harness directly to ground with a screw on the
furnace chassis. See diagram.
STEP 14
Once all of the connections have been completed,
remount the IFC control platform into the furnace.
STEP 15
Secure any loose wiring with wire ties.
STEP 16
The brown and white wires from the EAC wiring harness
are unused in this application and should be insulated.
See diagram.
STEP 17
Replace the furnace door.
STEP 18
Replace the furnace door.
STEP 19
Check both furnace and air cleaner operation per the
furnace and air cleaner installer guides.
