19. Press the Extra Cycle button once. Set the time of the night that you want the Birm Filter filter
to backwash. The default time is 2:00 am. Adjust the time by pushing the up or down arrow if
you want.
20. Now press the Extra Cycle button once more. You are done programming!
21. Now you are ready to turn on the water. Turn on the water and leave the Birm Filter on bypass
and check for leaks. Leave the ball valve after the Birm Filter closed, so water is still off to the
house, but connect a garden hose and open up the hose bib after the Birm 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 Birm
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.
22. Press the Extra Cycle button for a second or two which will start a manual backwash.
23. 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.
24. There should be no Birm media coming out of the drain line, but the water will be gray or dirty
looking. At this point the Birm 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 Birm Filter at first to
prevent some Birm 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.
25. If possible verify that the backwash flow is 5 gallons per minute, which is the recommended
backwash flow rate for 1.0 and 1.5 cubic foot models. If you have a 2.5 cubic foot Birm Filter it
should be backwashing at 10 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 Birm media and prevent it from cementing together.
26. The next cycle is the Rinse cycle and this also runs for 10 minutes.
