I am part way through the installation.
I am hoping to finish it off today. I need to go to the hardware store to get a 2" Tee so I don't have to use the pvc saddle.
So far I have run into a few problems, but it is working and is just ready to be screwed down to my pad and the wires and hose all neatly tucked into place.
Here is my panel before the installation:
My Jandy iAqualink panel has several open Relays - I at first figured I would use Aux 7 and hooked it up that way. During all of my programming it would never energize Aux 7. So I am not sure what that problem is (maybe I don't have an RS8). After resetting all of my Aux settings in the programming I finally switched it to Aux3 and it started to work correctly.
My second problem is that I wanted to wire the power supply up via the pump, so that it would only turn on when the pump was running as a safety backup.
Here is a drawing of what I was attempting to do. The red line shows the location of a the wire that I used to connect to one leg of the pump relay so that I could have the power supply get its power only when the pump was on. This went to the AUX3 relay and then to the power supply line and load contacts. Unfortunately this didn't work and caused th 240v pump circuit breaker to trip anytime the AUX3 relay was switched on. Since my drawing from a trusted electrical engineer showed it wired this way, and I also saw another version of this on a Pentair power unit in the thread linked earlier, I thought it should work...
I either wired it wrong and/or my circuit breaker can't handle the extra load of the small power supply and that is why it trips the breaker.
In order to get it working and test everything I switched it out and wired it to the 20A 120v circuit that powers the Jandy panel. This goes through the AUX3 relay to turn the power supply on and off as needed. It currently works. One minute of pump run time puts out around 5oz of liquid.
As a precaution I set a 1 minute time duration limit for the AUX 3 relay via the iAqualink programming. This means that even if the pump is off for some reason (but scheduled to be on), and the Acid Pump schedule calls for the Acid Pump to run, it will only inject around 5oz of weak MA acid into the pipes - which should never be a huge issue. I am not sure it would ever happen...
I will post some pictures later today of the finished wiring and the installation of the tank. That is what I am off to do now!
