Water flow problem:
-
Filter pump failure,
- Filter and/or the skimmer(s) are dirty,
- Disconnection or failure of the flow
switch.
•
Check the pump, the filter, the skimmer(s) and the
by-pass valve(s). Clean them if necessary.
•
Check the wire connections (flow switch).
•
Check that the flow switch is working correctly:
replace it if necessary: contact the retailer)
• The appliance has stopped producing.
•
Increase production. Clearly distinguish the
appliance's actual production and the setpoint.
•
Have the control box checked by a qualified
technician.

The values are not
displayed.
• The appliance is in standby.
•
Unlock the screen (see § “4.1.2. Unlocking the
screen”.
•
Deactivate the energy saving mode so that the
values can be read when the device is in standby,
see § “4.3.15. User interface energy saving mode”.
Tip: if you require assistance, inform your retailer about the appliance's condition to save time
7.2 I Effects 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 chlorination 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 and 1 ppm of free chlorine will correspond
to 500 mV.
•
If the user keeps the setpoint at 700 mV, a chlorine concentration of 5 ppm will eventually be obtained.
