g. Shut off pump.
h. Set Filter control valve to FILTER.
i. Proceed as in Pre-Coating to add fresh D.E.
(C) RINSE – Water Flows through the filter the same as in FILTER position, except that the water goes to WASTE. An optimal
position used for pre-coating if a large cloud (pre-coat puff) is observed returning to pool during the pre-coating process.
(D) WASTE – To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to WASTE.
(E) RECIRCULATE – Water is re-circulated through the pool system, bypassing the filter.
(F) CLOSED – Shuts off flow from pump to filter.

FILTER CONTROL VALVE FUNCTIONS

MANUAL CLEANING

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 accumu-
lated 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.
