On my new 30K gallon pool, I've had a Pentair IC40 cell installed and running for a couple weeks now (for the 3 months prior to that I had the "dummy" pipe cell installed in its place, and was manually chlorinating). I'm still dialing the SWG in but currently with my CYA at 80ppm I'm running the SWG at 100% duty cycle from 10am to 7pm (9 hours) to maintain FC at ~ 6ppm. I would have been better off with the IC60, but the IC40 is what the builder installed and I didn't know any better then!
The issue that I need help with is that I'm finding the SWG flow indicator is intermittent at pump speeds lower than 1725 rpm. I define intermittent as I set a pump speed and watch the SWG flow indicator for 15 minutes, and if it goes red I call it intermittent. So currently I have the pump programmed to run at 100 rpm above (1825 rpm) which is using a little over 300 Watts of power.
I was hoping I could run the pump at a speed where it would use less than 200 Watts like others have, and am looking for anything I can change in the plumbing. It was not plumbed in per the installation guide recommendations (my guide is dated February 2016), there is a 90 degree elbow 6" from the SWG inlet, and a Pentair check valve 6" from the other side of that same elbow. There is also a 90 degree elbow 5" from the SWG outlet. I removed the flapper/spring assembly from the check valve but that didn't give me any improvement.
So I'm considering re-doing the plumbing to put the recommended full 12"-18" of straight pipe in front of the SWG cell inlet "for best flow sensing" (per the installation guide). But the guide also says, "Install IntelliChlor SCG cell vertically for best performance" (the title of this post).
So while I'm at it, should I install the cell vertically? Does anybody know or have a theory why this statement (to mount vertically) is in the manual?
Maybe when mounted vertically, the flow is more "laminar" which allows the flow switch to operate better? Or maybe mounting vertically allows the chlorine gas to more easily escape the cell? Just guesses, not sure. I called Pentair tech support and didn't really get a solid answer. Just wonderin' what you all think.
Thanks,
Mike
