Periodically you have to clean the debris and contaminants out of your Hayward DE Filter. This process can be done at three levels: 1- by backwashing the filter; 2- by extracting and cleaning the grid assembly; or 3- by extracting and cleaning each grid in the assembly. For more information on Backwashing, see our guide on "How To Backwash a Hayward DE Filter". For a more thorough cleaning, you can extract and clean the grid assembly about twice a year. For more information on clean the grid assembly, see our guide on "How To Clean a Hayward DE Filter Grid Assembly". For the most thorough cleaning, you should pull the Grid Assembly and take it apart to wash down each Grid individually. This guide addresses this last procedure.
LOCATE PARTIAL GRID - This Grid Assembly has 8 grids, a partial or short grid and 7 full grids. The Partial Grid has been shortened to accommodate the Manifold Pipe that fits into the side of the Grid Assembly. Before removing the Top Manifold, locate where the partial grid is placed. It will be under the arm of the Top Manifold that is labeled "Short Element Here". When you replace the Top Manifold, it has to go together in this same configuration.
REMOVE PARTIAL GRID - To avoid confusion on where each grid goes, many people take the grids out one at a time to clean them. With the Top Manifold off, you may need another person to hold the grids in place as you are pulling them out one at a time. We have started with the Partial Grid but you can pick any other starting point. Pull the Partial Grip straight up out of the bottom guide. Note how the grid fits into the bottom so you can replace it the same way.
REPEAT FOR REMAINING 6 GRIDS - Taking the grids out one at a time, repeat the last four steps for each of the remaining 6 Full Grids.
