Installing Aqua-Sensor
1. Locate the Aqua-Sensor 2.5VAC power cord and bushing (P/N 01025264) packed in the small parts pack. The
power cord has two spade terminals on one end of the cable and a plastic female connector on the other end.
2. Disconnect power from the circuit board.
3. Remove the power cord bushing (P/N 01025274) from the outdoor enclosure (location #1 in Figure 24) by loos-
ening the nut from the 24V power cord bushing.
4. Discard the dummy connector on the 2.5VAC circuit board
pins.
5. Remove the bushing cable assembly from the enclosure.
6. Press a small screwdriver into the slots on the plastic female
connector housing to remove the two metal slip-in tabs on the
24V power cord. See Figure 27.
7. Remove the P/N 01025274 bushing from the 24V power cord.
8. Insert the 24V and 2.5VAC power cords through the shared
bushing (P/N 01025264). See Figure 28.
9. Use a small screwdriver to raise the tongue on each metal tab
so it is protruding at the top. Reinstall the tabs in the housing.
Tug lightly on the cord to make sure the tab does not pull free
from the housing. See Figure 27.
