What is the Pentair Intellichlor Dummy Cell used for?
Reply
The Dummy cell is basically a cell with no internal parts, this cell is used during cleaning of the real cell. So when you remove the real cell for cleaning you would put the dummy cell in place of the real cell. After you have finished cleaning the real cell you would remove the dummy cell from the plumbing and place the real cell back in place. You may view or purchase the Dummy Cell here >http://www.inyopools.com/Products/03500001032551.htm

opened the breaker, unplugged salt generator from power supply, unscrewed salt generator, put new rings on the old fittings, screwed in new generator, plugged in new generator, closed breaker. vacuumed the pool, that was the hard part. Magic happens. green to clear blue in 3 days.
I had a flow error so I replaced the flow switch a few weeks earlier but it didn't clear the alarm.
Thanks inyo folks!

$200 cheaper than same product at other pool supply stores. Works great. Only problem is lettering on top is upside down for us to read with the direction water flows on our system.

The intelliichlor cell is great. You don't have to constantly add clorine tabs and don't have the negative effects of clorine!
