Page 7 of 12 Clamp Nut Pro-GridTM VERTICAL D.E. SERIES FILTER ISDE2423 REV C INITIAL CLEANING OF ELEMENT CLUSTER ASSEMBLY Before removing the element cluster assembly we recommend hosing it down with a strong stream from a garden hose or preferably with the Hayward cleaning wand (EC2024). Be sure the drain plug is not in place or the drain valve is open. Remove as much of the dirty D.E. and accumulated debris by flushing it out of the drain opening. This will allow for easier removal of the element cluster assembly. REMOVING ELEMENT CLUSTER Rock the element cluster assembly slightly from side to side to free the manifold from the vertical outlet elbow. The element cluster assembly may now be removed by lifting it straight up using the lift handles. Figure 4 CLEANING ELEMENT CLUSTER The filter element cluster can be cleaned by washing inside and outside with a garden hose. After hosing filter element cluster, for best results, carefully brush the surface to remove fine particles. Do Not Pressure Wash as it can damage the filter element cluster. You may find some debris on the filter element cluster, which may not have been removed with hosing.
