Installing the Battery Unit

1

  • Isolate the water supply.

2

  • Cut the pipe and flush it out with water.
  • Fit the valve horizontally (vertically in the direction of the arrow), leaving the petcock in place to regulate the flow.

3

  • Select a position for the Water Watch near the urinals where it will detect use.
  • Attach the base-plate to the wall/ceiling.
  • Note that the control box hooks under the bottom edge and is retained by raising the head of the internal screw as shown below:

4

  • Wire the 1.1m cable from the valve to the Water Watch controller.
  • If the cable is not long enough it can be extended using the two-way terminal block provided.
  • Leave a small loop inside the controller so that the lid can be detached from the mounting plate.
  • Attach the battery connector.

5

  • IMPORTANT!
  • This step is critical because it tells the unit how long the cistern takes to flush. It can then release the water supply at the precise time required for the selected flush cycle.
  • To complete this, follow the simple ABC below:
A

Start with the cistern empty and the valve closed as show below.

B

Open the valve into the position shown.

The lamp will flash on detection.

C

When the flush starts, wait a few seconds for it to establish, then CLOSE THE VALVE.

The time taken for the cistern to fill will now be memorised and used in all subsequent automatic flushes.

Note that only fill-times greater than 1 min. are saved.

The Water Watch is now fully operational!

Close the lid.

  • Never leave the switch in the ‘open’ position.
  • If the lamp if flashing, check that the switch is in the correct closed position.
  • The lamp will now only operate when the battery needs changing.
  • Remember that only fill-times of greater than 1 minute will be saved.
