Installation 21
Cat. No. 01024821
NOTE The wire connectors must be connected to the circuit board properly. The wires must exit the plug-in
connector opposite of the raised white base of the circuit board connector. Failure to properly connect
any of the connectors will result in a malfunction of the circuit board operation.
13. Connect the other end of the power cord, with the spade terminals, to the two 2.5VAC terminals on the trans-
former. See Figure 26.
14. Insert the Aqua-Sensor sensor probe wire harness through the Auqa-Sensor connector opening at location #3
on the controller enclosure. See Figure 21.
15. Tighten the nut on the interior side of the port opening on the controller enclosure. See Figure 23.
16. Connect the Aqua-Sensor probe wire harness bushing to the circuit board. The Aqua-Sensor probe terminal is
labeled “Aqua-Sensor.” See Figure 26.
NOTE The 230 VAC transformer does not have 2.5 VAC connections. The Aqua-Sensor probe cannot be used.
