How long it lasts
Replace it when the controller keeps showing low salt, no flow or low output after the salt level has been checked and the cell cleaned, AstralPool says; check the cell for calcium every fortnight.
After replacing: No reset needed. After fitting, run the pump, switch the chlorinator on and set the output again; the low-salt or no-flow warning should clear once water is flowing through the new cell.
How to change the 21908 chlorinator cell
Watch the guide or follow the steps.
- 1Turn the chlorinator off at the power point, turn the filter pump off and close the valves either side of the cell if you have them.
- 2Disconnect the cell lead: on the VX and Viron undo the wing nuts (note the blue wire is on the blue terminal); on the E-Series and eQuilibrium unplug the cell terminal cap; on the Halo unclip the end cap.
- 3Undo the two barrel unions and lift the old cell out of the pipework.
- 4Fit the new cell level, with the barrel unions underneath, the O-rings seated and the water entering at the end nearest the terminals (follow the flow label). Tighten the unions.
- 5Reconnect the lead, open the valves, start the pump and check for leaks, then switch the chlorinator on and set the output.
