Note: Instructions for Mk1 Water Level Meters are on page 3 (Molex
cable connection, soldered connections to battery tray).
1. Place the reel on a flat surface, with the faceplate up.
Remove the battery from the Meter.
2. Use the Phillips screwdriver to undo the three screws holding
the faceplate to the hub. Remove the faceplate.
3. To disconnect the cable from the circuit board, press
down on the white terminals of the push-release fittings on
the circuit board and pull out to remove the cable leads.
Remember how they were connected.
4. Unscrew the nut from the test button and push the button
out of the faceplate.
5. Use the small flat screwdriver to unscrew the small brass
screw on the side of the sensitivity knob. Remove the
sensitivity knob. Use the pliers to unscrew the nut holding
the sensitivity switch and remove the switch from the
faceplate.
6. Use the Phillips screwdriver to undo the two screws holding
the battery tray to the faceplate. Remove the black and red
wires by pulling the quick-connect fittings off of the terminals
on the battery tray. Remove the battery tray.

connected (see photo above).
10. If you have a new style light, unscrew the red lens from the
faceplate.
11. Unscrew the Sonalert retaining ring from the front of the
faceplate and remove the Sonalert.
12. Put the Sonalert through the new faceplate, and secure it
using the retaining ring. Position it as shown in the photos
above, depending on which light you have.
13. If you have a new style light, install the red lens in the new
faceplate and secure it using the white nut.

15. Place the circuit board assembly back in position on top of
the Sonalert, ensuring the sides marked +ve and -ve are
lined up with the corresponding terminals on the Sonalert
and if you have a new style light, it is seated in the lens (see
photo below).
16. Use the two screws to connect the wires from the circuit
board (and light if you have the older style) to the Sonalert.
Make sure the wires are connected to the correct terminals
(+ve and -ve) on the Sonalert.
17. Insert the test button through the opening in the faceplate,
and secure it in place using the nut.
18. Insert the sensitivity switch through the faceplate with the
three connection prongs positioned towards the battery
drawer, slightly towards the centre of the reel. Tighten the
nut. Fasten the sensitivity knob on the front of the switch
using the brass screw.
19. Insert the battery tray through the faceplate and secure
using the screws. Connect the black wire with quick-
connect fitting to the negative terminal on the battery
tray. Connect the red wire with quick-connect fitting to the
positive terminal.
20.To reconnect the cable to the circuit board, press down on
the white terminals and insert the cable leads. Release the
terminals and the leads should be secured. 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 (see illustration below).

21.Replace the battery. 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 connections and
the polarity of the battery.

6. Use the small flat screwdriver to unscrew the small brass
screw on the side of the sensitivity knob. Remove the
sensitivity knob. Use the pliers to unscrew the nut holding
the sensitivity switch and remove the switch from the
faceplate.
7. Use the Phillips screwdriver to undo the two screws holding
the battery tray to the faceplate. Cut the red and black wires
from the back of the battery tray close to the terminals (other
end of black wire is connected to the sensitivity switch, and
red wire connects to the circuit board). Remove the battery
tray. Strip the wires about 1/4" (6 mm).
8. Unscrew the Sonalert retaining ring from the front of the
faceplate and remove the Sonalert.
9. Put the Sonalert through the new faceplate, and secure it
using the retaining ring.
10.Replace the sensitivity switch, light, and test button in the
new faceplate.
11.Reconnect the two wires, from the light, using the two
screws through the circuit board and onto the Sonalert.
12.Insert the battery tray through the new faceplate. Re-solder
the red and black wires to the correct terminals labeled on
the back of the battery tray. Red wire from the circuit board
to the positive terminal and black wire from sensitivity switch
to the negative terminal. Use the two screws to secure the
tray to the faceplate.
13.Connect the Molex connector from the faceplate to the cable.
14.Replace the battery. 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 the polarity of the
battery and Molex connector, and the soldered connections.
15.Screw the new faceplate to the reel using the new Phillips
screws.
