2. Use the screwdriver to undo the three screws holding the
faceplate to the hub. Remove the faceplate.

3. If this is a Mk1 Water Level Meter, disconnect the Molex
connector that connects the circuit board to the tape/cable.

If this is a Mk2 Water Level Meter, press down on the white

terminals of the push-release fittings on the circuit board
and pull out to remove the tape/cable leads.

Molex

Connector

4. To connect the new faceplate with electronics, connect the
tape/cable to the new circuit board assembly:

a) If this is a Mk2 Water Level Meter, press down

on the white terminals on the circuit board and insert
the tape/cable leads. Release the terminals and the
leads should be secured.

For 101 Water Level Meter, the lead on the bottom of

the tape (numbers facing up) is inserted into the
terminal with a white square below it on the circuit
board (see next page for images).

For 102 Water Level Meters, the positive lead is

inserted into the terminal with a square etched
below it on the circuit board. The positive lead has
the pin connected to insulated wire, the negative pin is
connected to the braided wire.

b) If this is a Mk1 Water Level Meter, with a Molex

connector on the tape/cable leads, remove the Molex
connector by pushing out the two pins. Cut each pin
in half (see image on next page for correct location).
Use pliers to flatten the remainder of the pins against
the tape/cable lead, so it fits easily into the terminals
on the circuit board. Connect each tape/cable lead to
the new circuit board assembly, as described above in
step a.

5. Install the battery.

6. With the probe in a glass of tap water, turn the Water Level
Meter to the ‘ON’ position. If the connections are correct
the buzzer and light will activate. If the buzzer or light do
not activate, check all connections and the polarity of the
battery.

7. Reattach the faceplate to the reel using the three screws.
