Howdy,
We have a Hayward T3 Cell (GLX-Cell-3-W) SWG warranty replacement cell which is <1 year since installation. The first cell failed after <3 years. We have frequently have had issues with the original cell and the replacement cells reading low salinity when compared with Taylor test kit 2006-Salt results.
Since the end of April the SWG has been flagging salt level too low (blinking low salt light). In April I removed and inspected the cell. After running during the winter and early spring, there were mineral deposits and a brown film-like coating in the cell. Jetting water into the cell did not remove the scale and minerals. I cleaned the cell with dilute MA-Water solution recommended on this site and by the pool technician that replaced our cell. I cleaned the Swim-Clear filter, skimmer basket, pump basket filter with water at this time as well. Initially the salt level improved to 2800. This week the SWG was reading 2600 ppm or lower, while the test kit was showing 3000 ppm. When the salt level dipped below 2600, the low salt light was on, not-blinking, and chlorine was not being generated. Free Chlorine dropped below the recommended range (1 ppm!) and I started adding liquid chlorine based on the cool Pool Math app.
Not wanting to invest in a SLAM this early in the season, I researched the TPF site. This wiki was really helpful for understanding the SWG system, and I have a few questions I am hoping the group can help with. ( Hayward Aquarite SWG - Further Reading )
Our cell is installed horizontally and sits on a 'concrete' pad next to the pump and filter. We have a variable speed pump which was programmed to run primarily at 2025 RPM. The cell is positioned with the cord side at the top, and the cord end at the cell's inflow side. Based on the wiki above, it looks like the cell should be positioned with the cord side at the bottom, and the cord end at the cell's outflow side. The most I can move in this direction is to turn the cell to be on its side, with the cord side 90 degrees from top or bottom. Since rotating the cell late yesterday, the SWG is showing very close to the test kit (3000 or 2900 ppm).
1. In either position, it appears the SWG is always generating (generating light on), and I wonder if this is due to the internal plates potentially not being covered in water.
2. What is the significance with the cord end on the cell's outflow side (shown in wiki) vs. the cell's inflow side?
3. Is the 90 degree rotation going to be an adequate long-term solution, or should I try to re-plumb the piping to allow for the cord side to be at the bottom?
Images are below. Water flow is from left to right in the images.
Thank you!
