Intellichlor IC40 flow rate

[gatorbrit]

My IC 40 gives me a red light indicating that the flow rate is too low. But I am certain that the rate is ok - I’ve run my pump in prior years at lower rates and the IC40 has been fine.

When I increase the flow rate to much higher - it works ok. It is just not activating at lower speeds.

Is there a way to adjust the sensitivity of the IC 40 - I see I little strip that hangs done in the way of the water which I think is the flow sensor. It just looks like a simple switch.

gb,

It is nothing but a magnetic switch... There is no official adjustment, but I suppose you could just bend it a little and see if that helps..

Will it work at all? I had one break off inside the cell and of course it would then never come on...

Does your switch close when you increase the pump's speed? I have to run mine at 1200 to keep the switch closed.. How fast are you running your pump?

It could also just mean that your filter is dirty....

Worst case, it is a simple $100, or less, DIY fix..

Thanks for posting,

Jim R.

My pump has to run at more than 2200 rpm. I am pretty sure that I could get away with a lot lower speeds when I first got it.

Anyhow - thanks for the input - after a google search I decided to order an new sensor for $50.

My IC40 threshold is around 900rpm with my Pentair Intelliflo pump. I usually run mine at 1200rpm just so I know I'm safely above the threshold. There might be some variations with flow based on plumbing configuration.

The only other likely problems could be a dirty filter or scale build up in the cell. If you recently backwashed and checked to make sure the cell is clean then you're on the right track. My cell runs fine at 1100 rpm. 2200 rpm is way too high.

Is it under warranty or is that not covered or too old or just not worth the hassle of going through warranty?
