OZONE XLM Series Status Indicator, Warnings and Safety
Shutdowns
There is a STATUS indicator on the front panel that simply shows green (OK) and red
(WARNING). The reason for any WARNING will be written on the LCD display. Possible
warnings are explained below.
Low Water Temperature & TDS
Low water temperature and lower than recommended mineral levels can both cause low
conductivity of the water to be detected.
The Ozone XLM Series will, however, continue to function and will display this without a
red warning indication. Simply check the TDS level and make sure it is well above 800ppm
(ideally around 1000ppm or a little more).
Check the temperature of the water, and if it is lower than 20ºC, you may wish to adjust the
Water Temperature setting using Advanced Settings Menus (information on Advanced
Settings available via www.poolcontrols.com.au or by calling Pool Controls Service on
1300 550 010.
Gas Detection & Dry-Run Pump Shutdown
This is an important safety feature of the Ozone XLM Series as a build-up of chlorine gas
can be dangerous.
The display above left shows the Cell being turned OFF after chlorine gas is detected for
approximately 10 seconds. If gas is still detected after approximately 2 minutes the pump
will also be turned OFF – and the display will read as shown above right.
To re-start the pump, simply press the ON-button (as instructed by the display). This will
reset the warnings and allow the pump to run (for a maximum of 3 minutes if gas is still
detected).
