GRE SIMPLEO 120 AR2085 Manuel D'installation Et D'entretien page 8

There are several causes for this alarm:
The electrode may be covered by deposits of limescale
Too much salt
Short-circuit in the electrode connections
A fault in the electronic control box
CORRECTIVE ACTIONS
1 – Remove the electrode and inspect its state visually. If you can see a large quantity of limescale
deposits, immerse the electrode in a solution of pH corrector (negative pH) until the limescale
disappears completely. Never rub the electrode plates nor submerge the connection terminals.
Rinse the electrode and replace it in the cell.
The self-cleaning function of the electrode prevents the formation of limescale deposits in the
majority of cases. However, in regions with exceptionally hard water or "unbalanced" water
(see the Taylor Balance diagram), manual cleaning of the electrode or a treatment to balance
the water may be necessary.
2 – Contact a pool specialist who can advise you on replacement of the electrode.
3 – Contact our technical:
Have the following items at hand:
The purchase invoice
The serial number of the electronic control box and the electrode
The installation date of the unit
The name of the specialist who sold you and/or installed the equipment
The salinity, pH, chlorine concentration, water temperature and stabiliser concentration in
the pool
The volume of the pool and the daily operating time of the filter system
7. WINTERING
When the water temperature drops below 15° C, the unit must be turned off to avoid
irreversible damage to the electrode. In these circumstances, substitute the treatment with a classical
chemical treatment.
