Installations

Step 1:

Turn off the water supply.

Step 2:

Cut the pipe and flush it out with water. Fit the valve, leaving the petcock in place.

Step 3:

Select a position for the Water Watch near the urinals where it will detect use.

This can be either on the wall or the ceiling, a minimum of 12 cms away from the edge to allow space for the use of a standard screwdriver.

Attach the base plate to the wall or ceiling.

The control box hooks under the bottom edge of the backplate and is held in place by raising the head of the internal screw.

Step 4:

Cable between the valve connector and the Water Watch

Note that the valve actuator can be positioned either up or down

Inside the Water Watch leave a small loop of cable as slack so that the lid can be detached from the mounting plate.

Alternatively remove the blanking plug from the top of the Water Watch and feed the cable through the top cable gland.

Step 5:

Start with the cistern empty. Inside the Water Watch, the valve switch should be in the 'CLOSED' position.

Open the valve. The lamp will flash on detection. Inside the Water Watch, the valve switch should be in the 'OPEN' position.

When the flush starts, wait a few seconds for the flush to establish. Then close the valve. (Inside the Water Watch, the valve switch should be in the 'CLOSED' position.)

The time taken for the cistern to fill during set-up is stored and used for all subsequent automatic flushes.

Water Watch is now fully operational!

Close the lid.

If the lamp is flashing, check that the valve switch is in the correct 'CLOSED' position. The valve switch must never be left in the 'OPEN' position.

The lamp will now only operate when the battery needs changing.

For instructions on how to change the flush settings, see the Maintenance menu.
