New AquaRite S3 Instant Salt Reading

[MkoSharkII]

Hey all. Long time lurker and Pool Math user.
I’ve just recently finished upgrading my pad to 2” piping and installed a new AquaRite S3 with the 25k cell.
My question for any S3 users is whether the “Instant Salt” reading should ever simply read dashes as seen in my attached photo? The system has been powered on for about 24 hours now with the pump running continuously. For reference, salinity should be around 2500ppm based on the 10 bags I’ve started with (well dissolved and circulated at this point).
I have seen documentation where cell voltage can display 0.00 below 50°, but nothing regarding the instant salt dashes.
Thanks for any insight folks!

The water is simply too cold for the cell to work therefore the cell is off (cell current 0.00) and the salinity works via the cell current. Just looking at the cell location, has the manual given a minimum of straight pipe before the cell? Can't say it won't work but that's very close to the 90 out of the filter.

Gotcha, thanks!
Regarding the straight run, there’s no guidance or spec for the cell, but a minimum of 12” is required for the flow switch. For what it’s worth, I have watched the flow through the cell plates when the pump is priming, and there’s no visible cavitation.

Just realized your flow switch on the bottom. Not good at all. The down flow of water can keep it closed even if the pump is off which is no no. Also the cell should be tied into the pump so it can't run without the pump on and the flow switch is only a secondary safety which in your case isn't working as per design.

Thanks. I did consider that regarding the flow switch but it easily remains suspended above the contact when at rest. I observed the live status on the S3 during a prime and then shutting the pump off, and the switch operates properly. Additionally, there’s no guidance or documentation from Hayward implying this shouldn’t the done.
I did initially run a COMM cable from the pump to the S3, but come to find out Ecostars made prior to 2014 will not play ball without upgrading the display unit.
Considering that I run a 24/7 continuous pump schedule simply of varying RPM, I’m comfortable with the sole protection being the flow switch. I’ll simply have to test it periodically to ensure it’s opening normally.
