The electrodes...

The aligator electrodes are a composition of a number of alloys, the content of which took many years to establish. Under good pool management i.e.; keeping the balance of the water within range, the electrodes will last up to 18 months. The correct wear pattern should be a progressive reduction in the diameter until the electrode is slightly more than the width of a pencil. At this point they should be replaced. NB Any other pattern of wear indicates that the water balance is not being managed correctly.

Replacing aligator electrodes

Turn of the power supply to the pump and unit to ensure no water flows. Turn off any flow control valves fitted into the existing pipe work.

Access to the chamber is by unscrewing the top flange and gradually easing out the top transparent lid with a screwdriver. A rubber “O” ring situated around the base of the lid creates the seal. Once the lid is removed the electrodes can be replaced by releasing the 10mm stainless steel bolts securing them through the lid. Make sure on replacing the electrodes, the rubber seal is placed against the lid underface followed by the plastic washer then the electrode. On replacing the lid, make sure the location lugs are in line and the water flow arrow is in the correct direction before pushing the lid into the chamber.

Open any flow controls that were turned off and switch on the power supply to the pump and run, ensuring that the electrodes are once again underwater, switch on the power supply to the control unit. The electrodes should be submerged at all times that the control unit is functioning.

Check that the two green LED lights are once again illuminated.
