4.6 INSTALL MULTIPORT VALVE
1. Flip the valve assembly upside down. Install the valve/tank
O-ring so that it is seated below the valve body flange.
2. Seat valve onto filter tank with standpipe secured in center
port of the multiport valve body.
3. Make sure pump and return ports are oriented so that bends
and/or joints in plumbing are minimized.
4. Position the valve clamp so that it captures both the valve
body flange and the filter tank.

5. Position multiport valve clamp so that the bolts will be
accessible after the filter has been plumbed.
6. Use a Phillips head screw driver to secure the clamp.
7. Alternate tightening of the valve clamp from side to side.
8. Do not overtighten clamp.
4.7 PLUMBING
Make sure all plumbing connections are in
accordance with local plumbing and building codes.
1. Using appropriate pipe adhesive, connect the filter to
the pool water recirculation system.
2. Plumb the pump discharge line to the Pump Port on
the Multiport Valve.
3. Plumb the return line to the Return Port on the
Multiport Valve.
4. Plumb the waste line to the Waste Port on the
Multiport Valve.
5. Connect the pipes using the unions supplied with the filter. Do
not use PTFE (plumbers) tape or pipe dope on any union nuts.
Assemble the unions dry and hand tighten.
6. SFTM22-1.5 piping adapters are sized for 1.1/2” PVC pipe,
SFTM24-2.0 piping adapters are sized for 2” PVC pipe. In order
to reduce pressure loss, 2” (minimum) piping is recommended.
SECTION 5. OPERATION
This filter operates under pressure. When clamped
properly and operated without air in the water system,
this filter will operate in a safe manner. All plumbing
connections should be in accordance with local plumbing
and building codes.
Do not use pipe joint compound,
glue or solvent on the union nut threads.
5.1 FILTER VALVE FUNCTIONS
Filter pump must be turned off prior to making any
adjustments to the multiport valve.
When starting the
pump after making adjustments to the valve be sure to
stand clear of the filter. Ensure that all provisions for
waste water disposal meet local, state or national codes.
Set Valve Handle to:
•
FILTER:
Water passes through filter sand and returns back to the
pool. Set for Normal filtration operation. Multiport Valve should be
in this position for all typical filtration and sanitation circulation.
•
WASTE:
Water bypasses filter sand and is routed to waste port.
•
RECIRCULATE:
Water bypasses filter sand and is returned to the pool.
•
CLOSED:
Closes all passages through the Multiport Valve.
•
WINTER
This valve position leaves the multiport valve handle
disengaged and all passages through the valve open for draining.
Once the filter is drained, it is recommended that the valve handle
be kept in the Winter position.
•
BACKWASH:
Water passes through filter sand in reverse and is
sent to the waste port. With pump running, periodically check water
clarity in sight glass. Once water is visably clear, the backwash
cycle is complete.
•
RINSE:
Water passes through filter sand to waste. Use after
backwash cycle to clean debris from the Multiport Valve.
Rinse should run for 1-2 minutes.
