Fleck 7000 Sediment Filter Installation & Startup Guide
5. Feed water Hardness (Display Code H): Set to 10 to 20. This is the feed water hardness that allows
the meter to calculate the number of gallons between backwashes. It is a little meaningless for filter
valves, and is designed for water softeners which remove calcium hardness in grains per gallons.
However, if you set it to 20, to start with, you will later see the number of gallons between cycles
when you are finished programming based on your size of system. It is not that critical, because you
want the filter to backwash once a week or every few days based on the type of filter system you
have, by setting the Day Over-Ride.
6. Reserve Selection (Display Code RS): Set to SF. It is not relevant to filter control valves.
7. Safety Factory (Display Code SF): Set to 0.
8. Day Override (Display Code DO): Set to 1 to 14 based on your particular filter system requirements.
Use the Up or Down arrows to change the setting. This is the critical setting that allows your filter to
backwash every fixed number of days. See your Installation and Start-up Guide for more information
or contact us for suggestions for this setting. Press the Extra Cycle button.
9. Regeneration Time: (Display Code RT): Set to 2:00 am generally or sometime when no water is being
used, and no other filter or softener is likely to be in a regeneration cycle. Press the Extra Cycle
button.
10. Regeneration Cycle Step Times: Use this display to set the various minutes of each cycle. Some of the
cycles will be set to 0. Do not set any of the cycles to Off. Use the Up or Down arrows to change the
setting to the desired setting. Press the Extra Cycle button to accept the setting and move to the next
parameter.
