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)
