General Service Hints For Meter Control

Problem: Softener Is Producing Hard Water.

Cause could be that . . . Reserve Capacity Has Been Exceeded.
Correction: Check salt dosage requirements and reset program wheel to provide additional reserve.

Cause could be that . . . Program Wheel Is Not Rotating With Meter Output.
Correction: Pull cable out of meter cover and rotate manually. Program wheel must move without binding and clutch must give positive "clicks" when program wheel strikes regeneration stop. If it does not, replace timer valve head.

Cause could be that . . . Meter Is Not Measuring Flow.
Correction: Check output by observing rotation of small gear on front of timer with water running in house ( Note  program wheel must not be against regeneration stop ( 0 ) for this check ). Each tooth to tooth is approximately 30 gallons. If not performing properly, replace meter cover ( dome ).

 



PISTON STUCK 5600 CONTROL VALVE

                  It is very common for the main and brine pistons of the Fleck 5600 to need replacement after 5 -
                     10 years of use. The valve will get stuck trying to complete a regeneration cycle. Very often this
                     occurs at the beginning of the "brine rinse" cycle. The timer motor may stop at this point also.
                     The motors are made to stop instead of forcing the valve (which results in gear damage).

                     The solution is to replace the main piston  for water softeners  and the brine piston
                     assembly. If the valve is on a chlorinated water source or over 10 years old, it is
                     recommended to replace the main piston seals  at the same time.

                     On rare occasions the timer motor may also need to be replaced. But try the pistons replacement
                     first, this usually does the trick.

                     Another problem can occur with the Fleck 5600 Econominder (metered) valve. The gears inside
                     the meter dome cover fail. This can be due to a number of reasons.
The way to tell if this part needs replacement is to remove the meter dome, turn
                     the cable attached by hand and observe the small white gears inside. You should be able to make
                     them turn with normal finger pressure. They should also continue to spin for a brief moment
                     after you stop applying pressure. If you can not turn the white gears, you need to replace the
                     "meter cover". Most residential models use the standard range (0 -21, i.e. 2,100 gallons) black
                     plastic meter cover and matching program wheel on the control. There is an extended range (0 -
                              55, i.e. 5,500 gallons ) that is also available . Fleck also makes a brass 1" meter. This
would only be found on large commercial applications
