6.3 I Washing the pool fi lter (backwash) (in accordance to the model)
Backwash mode is used to quickly start/stop the fi lter pump (single- or variable-speed pump) in order to backwash the
fi lter.
• Press
and browse the menu using the
butt ons.
Press
to confi rm.
• Select
to acti vate fi ltrati on or
to stop fi ltrati on.
For safety reasons, the chlorinati on is stopped during the backwash mode. To avoid emptying the pool, the backwash
mode automati cally stops aft er 5 minutes. The variable speed pump RPM is by default set at 3450 rpm (max speed). This
can be changed in the priming menu.
6.4 I Winterizing
The chlorinator is equipped with a protecti on system that limits chlorine producti on under adverse operati ng
conditi ons like cold water (in winter) or when there is too litt le salt.
• Acti ve wintering
= fi ltering operati onal in winter: below 10 °C it is preferable to switch off the chlorinator.
Above this temperature you can leave it running.
• Passive wintering
= lower water level and drained piping: switch off the appliance and leave the electrode
dry in its cell with its isolati on valves, if any, open.
• Sensor wintering =
Keep the sensor’s plasti c tube (which contains a storage soluti on) to re-use it during
wintering. The sensors must always be stored damp (never dried out). They must be stored in the tube
fi lled with a 3 mol/L KCl storage soluti on or at least in tap water.
6.5 I Returning the pool to service
Required acti ons:
•
Adjust the water level (too much or too litt le).
•
Check the water parameters : TAC/TH/pH/Salinity/Chlorine/Stabiliser/Copper/Metals, and adjust the pa-
rameters to obtain a balanced, healthy pool, see
«4.1 I
Water balance
».
•
Check the conditi on of the equipment (pump, fi lter, chlorinator, electrolysis cell).
•
Check the sensors, clean if needed and re-calibrate.
•
Once the salt level has reached the required level of 4000ppm and is completely dissolved in the water,
restart the salt chlorinator.
