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.
Conrm 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
