RE-INSTALLING ELEMENT CLUSTER
1. Lubricate outlet elbow O-rings with Jack's Formula 327 Multilube.
2. Replace filter element cluster into filter tank, carefully fitting top collector manifold outlet over outlet elbow
O-ring.
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.
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.
