Instructions
1. Make sure the Well Casing & Depth Indicator is turned off.
2. To remove the old probe, twist the probe counter-clockwise
and slowly pull it away from the tape seal plug.
3. It will take some force to pull past the o-rings on the tape
seal plug. Ensure not to overextend the wire connectors
inside the probe.
8. If required, use tweezers to carefully pull the green and
white wire connectors from the replacement probe body.
9. To attach the new probe, connect the green wire to the
brass connector on the top of the tape seal plug and the
white wire to the bottom brass tube. Ensure the connectors
are pushed all the way onto the brass tubes.
10. Keeping the wires connected, slowly twist the probe up to
two times. This shortens the wires and allows them to tuck
easier into the probe body.

the probe clockwise until the probe seats on the tape seal
plug.

plunger at the bottom of the probe into the probe body.
If the connections are correct, the buzzer and light will be
activated. Check the connections if the Indicator does not
