Circuit Board Connections
To connect the Aqua-Sensor® probe and meter to the HE Twin Control #1 and motor cable, gear
box position cable, and the meter cable from HE Twin Control #2, proceed as follows:
WARNING! Disconnect all electrical power to the unit before
connecting.
CAUTION! Grip all connections to the circuit board by the connect-
ing terminals for assembly and disassembly. Failure to do
so could result in damage to the wire leads or connecting
terminals.
CAUTION! Do not touch any surfaces of the circuit board. Electrical
static discharges might cause damage to the board. Handle
the circuit board by holding only the edges of the circuit
board. Mishandling of the circuit board will void the war-
ranty.
NOTE Observe all state and local electrical codes.
1. Remove the electrical enclosure from both control valves. First remove the electrical enclo-
sure screw and then gently remove the enclosure from the control. Refer to Figure 19 and
below instructions.
2. Remove the 24 Volt power supply wire harness from the circuit board. See Figure 21.
3. Grip the circuit board from the edges and gently rotate it to the back of the enclosure (you
are disengaging the circuit board from the two support pins on the bottom of the enclo-
sure).
4. Remove the circuit board from the enclosure.
