6. Locate the Aqua-Sensor 2.5 Volt power cord packed in the small parts pack. It has two spade
terminals on one end of the cable and two metal slip-in tabs on the other end.
7. Insert the Aqua-Sensor 2.5 Volt power cord through the third hole on the enclosure. Insert the
Aqua-Sensor sensor probe wire harness through the forth hole on the enclosure. See Figure 19.
NOTE If additional accessories are to be connected to the circuit board (such as the
Smart Brine Tank Probe or a phone line for modem) insert both the Aqua-
Sensor 2.5 Volt power supply wire harness and the Aqua-Sensor sensor
probe wire harness through the third hole on the enclosure.
8. Connect Aqua-Sensor probe wire harness to the circuit board. The Aqua-Sensor probe terminal
is labeled "Aqua-Sensor." See Figure 22.
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.

9. Install the Aqua-Sensor 2.5 volt power cord.
a. The power connection to the circuit board should be INSIDE the controller. The spade
terminals should be connected to the transformer.
b. Discard the dummy connector on the 2.5VAC circuit board pins.
c. Connect the Aqua-Sensor power coard to the 2.5VAC pins on the circuit board.
d. Connect the other end of the power cord, with the spade terminals, to the two 2.5
VAC terminals on the transformer. See Figure 22.
10. Pull any excess cable wire out of the enclosure and route the wiring inside the enclosure to
avoid interference.
11. Insert the circuit board back into the enclosure.
a. Angle the circuit board opposite the front enclosure and into the support bracket on the
side of the enclosure.
b. Gently push down and rotate forward until you hear a click (the pins on the bottom of
the enclosure being inserted into the circuit board).
