8.3 I Eects of the stabilising agent on chlorine and ORP
A pool ideally has a stabiliser level of 30 ppm and a pH of 7.4.
1 ppm of free chlorine = 700 mV
The user can therefore adjust the chlorinaon requirements to 700 mV to maintain a level of 1 ppm in the pool.
If the level of stabiliser rises to 90 ppm, the ORP value will be incorrect.
1 ppm of free chlorine = 500 mV
If the user keeps the setpoint at 700 mV, a chlorine concentraon of 5 ppm will eventually be obtained!

8.4 I HELP menu
The appliance automacally reports any problems by way of informaon messages. To make these messages easier to
