I have an old style Aquapure 1400, with the square cell and the threaded sensor. It started giving the sensor error codes so I replaced the sensor. The unit is an old style with the removable plastic cover and, apparently, the AKC 13 board attached to the front cover.
The tri-sensor adapter board would only install in a position that I would think was upside down, with the printed circuitry towards the cover. There's nothing in the instructions or diagram about this, so I assume that was ok. Correct?
I hit the calibrate button in the adapter board, but it's reading 2.8 salt, whereas test strips say it's 3.5. The old sensor read closer to the strip reading.
Should I recalibrate rate the salt sensor as per the troubleshooting manual, or just leave it alone?
