Fleck 7000 Sediment Filter Installation & Startup Guide
16. Hold down the up arrow and down arrow at the same time for 5 seconds. Set the number of days
between backwashes, typically for 1 to 7 days. If your water is very clean (no sediment or iron) you
can set the backwash frequency to as little as every 14 days but its best to leave it to backwash every
1 to 7 days. If there is a lot of sediment in the water, you might want to set to backwash every 1 to 3
days, and if there is moderate sediment and low water use, once a week is fine.
17. Press the Extra Cycle button once. Set the time of the night that you want the Sediment Filter to
backwash. The default time is 2:00 am. Adjust the time by pushing the up or down arrow if you
want.
18. Now press the Extra Cycle button once more. You are done programming!
19. Now you are ready to turn on the water. Turn on the water and leave the Sediment Filter on bypass
and check for leaks. Leave the ball valve after the Sediment Filter closed, so water is still off to the
house, but connect a garden hose and open up the hose bib after the Sediment Filter and allow the
water to run for several minutes. This important step clears out any foreign material that may be in
the pipes from the piping installation. If you do not have a valve installed after the Sediment Filter
and you do not have a hose bib, you will need to turn the water on inside the house to let the water
run. Use a bathtub or laundry sink or other fixture that does not have an aerator screen.
20. Press the Extra Cycle button for a second or two which will start a manual backwash.
21. Now you can slowly turn the bypass valve to the service position. You do NOT remove the red clips
on the bypass knobs in order to turn the bypass valves from the bypass to the service position. First
open the Inlet Side of the bypass valve. Second slowly open the Outlet Side of the bypass until it is in
the full service position. The Fleck 7000 bypass valve knobs are a little stiff, so you can use a screw
driver placed in the holes to turn the knobs. Make sure you are turning the bypass valve knobs in the
correct direction which is counterclockwise as you face the bypass valve knobs.
22. There should be no Sediment media coming out of the drain line, but the water will be gray or dirty
looking. At this point the Sediment Filter will be in a backwash cycle. The backwash takes 10
minutes. If the water slows down or stops during the first 10 minutes of backwash, press the Extra
Cycle to move the Fleck 7000 control to the next cycle, the Rinse cycle. Then repeat the backwash
and rinse after the rinse cycle is done, by pressing the Extra Cycle again. If you have high water
pressure you may need to turn on the water slowly to the Sediment Filter at first to prevent some
Sediment fines from coming out the backwash. However it is normal for some small amount of fines
to come out during the backwash, although you do not want to see a large amount of media coming
out, which would mean you have very high water pressure, or the drain flow for the Fleck 7000 is
missing.
23. If possible verify that the backwash flow is 7 gallons per minute, which is the recommended backwash
flow rate for 1.0 and 1.5 cubic foot models. The 2.0 cubic foot models require 10 GPM an if you have
a 2.5 cubic foot Sediment Filter it should be backwashing at 12 gallons per minute. You can easily run
the drain hose to a bucket and using a watch verify the flow rate in gallons per minute. An adequate
backwash is critical to properly clean the Sediment media and prevent it from cementing together.
