Great! Open that manual to page 16.
CONFIGURATION MENU -> CELL TYPE
Cell Type Selection
The Cell Type Menu appears after “Display Salt/Minerals” in the Chlorinator Configuration
Menu. The options are T-CELL-15 (default), T-CELL-9, T-CELL-5 or T-CELL-3.
Make the proper selection based on the chlorinator cell that is used in your system (the
Aqua Plus includes the T-CELL-15). The available selections are listed below:
“T-CELL-3” = T-CELL-3, GLX-CELL-3-W
“T-CELL-5” = GLX-CELL-5, GLX-CELL-5-W
“T-CELL-9” = T-CELL-9, GLX-CELL-9-W
“T-CELL-15” = T-CELL-15, GLX-CELL-15-W
For the capacity of each cell see
Hayward Aquarite SWG - Aquarite T-Cells
You can then look at the physical cell and verify the cell type is correctly set.
