off if it is annoying, but remember to switch it back on again when the levels of Chlorine have been
restored.

1) Initial switching on of the unit
2) Chlorine drum is empty.
3) The control knob having been turned clockwise to increase the Chlorine level.
4) The filter has been off for a long period of time on a hot day.
5) The stabiliser level is very low or non existent and causing a high rate of Chlorine loss.
