WARNING
!
HAZARDOUS VOLTAGE! DISCONNECT ALL ELECTRIC
POWER, INCLUDING REMOTE DISCONNECTS BEFORE
SERVICING. FOLLOW PROPER LOCKOUT/TAGOUT
PROCEDURES TO ENSURE THE POWER CAN NOT BE
INADVERTENTLY ENERGIZED. FAILURE TO
DISCONNECT POWER BEFORE SERVICING COULD
RESULT IN DEATH OR SERIOUS INJURY.
PROCEDURE:
1)
Remove electrical power going into the air handler.
2)
On the communicating systems air handler, remove
the blower access panel.
3)
Remove the communicating control box cover.
4)
Locate the red jumper wire which is attached from
EAC to R on the Communicating Systems PCB.
Confirm it is connected. If there is not a jumper wire
installed, then one must be installed in this location
in order for the air cleaner to function properly.
5)
Replace the Communicating control box cover.
6)
Locate the white wire coming from the
Communicating System Air Handler PCB labeled
“EAC”. The wire will have a male spade terminal
connected to it and a female spade terminal
inserted into the male terminal. Remove the
female spade terminal and crimp it to the green
wire on the air cleaner harness.
7)
Connect the green wire from the air cleaner
harness to the white wire on the Communicating
Systems Air Handler.
8)
Using the wire harness supplied with the air
cleaner, connect the Red and Blue wires from the
air cleaner harness to “R” and “B” on the Indoor
Unit 24V Terminal Strip respectively.
9)
Connect the Black wire from the air cleaner wire
harness to earth ground by attaching the wire to a
grounded screw that is connected to the metal air
handler chassis.
10) Replace the blower access panel.
11) Re-connect electrical power to the air handler.
