No clear video for this cell yet. The steps cover it.

  1. 1Turn the chlorinator off (Pentair says working on the cell with it on will damage the unit) and turn the filter pump off.
  2. 2Have the cell lead disconnected from the power pack: Pentair says only a qualified electrical technician should open it.
  3. 3Undo the cell lock nut and lift the old cell out of the cell casing.
  4. 4Fit the new cell with the cell union O-ring in place and tighten the lock nut by hand.
  5. 5Have the lead reconnected the same way, start the pump and check for leaks, then turn the chlorinator on and set the output.

Common questions

What happens if I don't change the cell?
A worn cell makes too little chlorine, so the water turns green or cloudy, and turning the output up only wears it faster.
Does Pentair make a compatible cell?
Pentair makes the genuine cell. Compatible cells for Pentair models are made by other companies to fit the same models, and Australian sellers we track list both; each part page shows the genuine and compatible prices side by side.
Is there anything to set after changing the cell on a Pentair chlorinator?
No reset needed. Switch the unit back on and set the output again.
