Chlorinator cold water shutoff pentair

[Kcooter]

A new pool owner here - pentair
about 30 non consecutive hours of 32 and under and the chlorinator cold water shut off remains on - now it is 50degrees and still on

I am suspecting this is not normal !
ideas?

Most SWG do not work when the water temps are 60 or below. During the burrr time you have to add liquid chlorine to maintain your FC. It will not take much due the cold water.

K,

Welcome to TFP.. A great place to find out why your "suspecting" is not correct in this case...

As long as the water temperature is below 52 degrees the cell will go into cold water shut off. I'm sure there is a +/- tolerance in there, so they generally don't toggle right at 52..

This shut off has nothing to do with freezing.. The cell has an internal water temperature sensor that shuts the cell off.

When I get my first cold water shut off, I just turn the cell off for the rest of the winter. For me, it is not worth the effort to try and keep using the cell until the Spring.

I just use Liquid Chlorine during the winter.. It does not take much this time of year.

Thanks for posting,

Jim R.

Echoing all above PLUS when spring comes my ic40 never reads salt levels properly until about 70 degrees. So when that time comes be prepared to add salt but don’t freak out and over-adjust - just use bleach until it warms up.

Thanks for that input. I just learned something new! Do you use a salt test? Which one?

Kimkats I used the Taylor k1766 kit when I was troubleshooting 2y ago (failed ic flow/temp sensor). This spring I just used the swg reading and no issues.

(Also I kind of use calcium level change to estimate change in salt level and cya, so I kind of have an idea of how much stuff to add. Such bush league engineering may not be acceptable around this fine place though!)

LOL yeah we do kinda like test kit results.......
