•
Put the transparent cover back in position.
Check for leaks and leave the pump running in manual mode for 10-20 minutes in order to release the
air in the system.

Manual dismantling and descaling of the cell
•
If filtration is stopped, force it on for approximately one minute so that water flows through the cell in case
acid was just injected.
•
Isolate the by-pass loop on which the cell is mounted by completely closing the shut-off valves at the loop
inlet and outlet.
•
Disconnect the quick connectors of the cell power cables.
•
Unscrew the white barrel unions on either end of the cell, and remove the cell.
•
Screw the white blanking cap onto one of the cell openings, first making sure that the o-ring is correctly
positioned.
•
Turn the cell the other way round and stand it vertically on the white cap.
•
Pour white distilled vinegar or 10% Hydrochloric acid into the cell.
•
Wait until the scale is completely dissolved (stops frothing),
•
If scale is still present, empty the cell and repeat the procedure with vinegar or acid.
•
Rinse the cell with water.
•
Make sure that the o-rings are in position at either end of the cell and remount it. Put the installation back
into operational status (cell power cable, by-pass, valves, filtration timer)
10.6
Winterizing
10.6.1 Passive winterizing:
In the event that pool filtration is completely stopped during the winter, proceed as follows to avoid any
damage that could be cause by freezing or clogging with algae:
Close the two shut-off valves on the by-pass loop on which the cell and acid dosing pump are mounted.
ACID DOSING PUMP:
•
Rinse the pump tubing as follows to remove any traces of acid:
•
Pull the suction tube and strainer carefully out of the acid buffer tank and immerse it into a bucket
of water.
•
run the pump either in pH Reducing - Manual mode if filtration is running, or in Cell Cleaning
Manual mode if filtration is stopped.
•
When at least half of the bucket has been emptied, stop the pump.
