WARNING
– ALWAYS STOP THE PUMP BEFORE OPERATING THE MULTI-WAY VALVE.
Six-Position Vari-Flo™ Filter Control Valve SP0710XR50E or SP0715XR50E
(A) FILTER – Set valve to FILTER for normal filtering. Also use for regular Vacuuming.
(B) BACKWASH –
a. Shut off the pump.
b. Set Filter Control Valve to BACKWASH.
c. Start Pump and backwash approximately two minutes, or until water out waste line appears clean.
d. Shut off pump.
e. Set Control Valve to RINSE.
f. Start pump and operate for 20 seconds.
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.
⚠
WARNING
– Before manually cleaning the filter, backwash by following BACKWASHING instructions.
FILTER DISASSEMBLY INSTRUCTIONS
1. Turn off all system circulation pumps and all electric power on the pad.
2. Set all system valves in a position to prevent water flow to the filter.
3. The manual air relief valve must be placed in the OPEN position. (FIG 2)
4. Remove filter drain plug (FIG 4) and drain water from filter.
5. Using ¾ inch wrenches, loosen and remove the clamp nut and the clamp bolt.
6. Holding both ends of the filter body clamp carefully spread the clamp ends. Remove the clamp by lifting over the upper
filter body. Do not to drop the clamp during removal because the clamp could be damaged. Do not strike the clamp with
metal tools as they can damage the clamp.

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.
