• MANUAL DISMANTLING AND DESCALING OF THE CELL:
1.
case acid was just injected.
2. Isolate the by-pass loop on which the cell is
mounted by completely closing the shut-off
valves at the loop inlet and outlet.
3. Disconnect the quick connectors of the cell
power cables.
4. Unscrew the white barrel unions on either end of
the cell, and remove the cell.
5. Screw the white blanking cap onto one of the
correctly positioned.
6. Turn the cell the other way round and stand it
vertically on the white cap.
7. Pour white distilled vinegar or 10% Hydrochloric
acid into the cell.
8.

9. If scale is still present, empty the cell and repeat
the procedure with vinegar or acid.
10. Rinse the cell with water.
11. Make sure that the o-rings are in position
at either end of the cell and remount it. Put the

• WINTERIZING
• A) PASSIVE WINTERIZING:
during the winder, 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 pH-Clear pump are mounted.
• PH-CLEAR 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
emptied, stop the pump.

pumping circuit to empty into a bucket placed
below.
• CELL:
• Descale and clean the cell (ref VIII.5), either

•
remove it.
• PROBES
• Cut the power supply to the electrical/ control
panel;
• Disconnect the probes from the electrical/ control
panel;
• Close the shut-off valve on the by-pass loop on
which the probes are mounted;
• remove the probes and place them in their phials
of buffer solution and store them in an area
protected against freezing.
