Metered Demand Control. 120 volt 60 Hz ( unless you select differently ).
* If you need / want
24 volt then order the "L" version, as they come 24 volts now ( since 2022 ).
Your "backwash" rate ( and injector installed ) is all determined by the Diameter of the RESIN tank the valve is to be used / installed on.
Tank Diameter - How To Measure and Why If this Valve is to replace an existing Fleck 5600 valve,
then the existing By Pass or Piping Yoke will clip on to the valve.
* Select "NONE".
Otherwise you will NEED to Select with valve order,
Either
A Yoke - standard Noryl plastic piping connection in either 3/4" or 1" male threads,
OR
A By-Pass Option can be selected ( again with 3/4" or 1" piping threads to match your plumbing ).
NOTE: Valve Cover ( for outdoor use ) is an option you may want to order separately if you need one. We include at no extra charge, a new distributor kit.
This is part # MD1236. It is a plastic lower screen which can be cemented to a piece of 3/4" PVC pipe to construct a new distributor tube. Your old distributor could be slightly smaller than the ones now used by both Fleck and Autotrol ( old size 13/16", new size 1.05" outer diameter ).
We also include a 1.05 Top Distributor Twist On - part # MD1203 at no charge.
