16. Turn the program knob slowly a few degrees clockwise to start a manual backwash. You will hear the
piston engage and move the piston to the backwash position. If you wish, you can swing open the
timer assembly to see how turning the knob on the front moves the program wheel on the backside
of the timer. Each pin or hole equals 2 minutes.
17. Now you can slowly turn the bypass valves to the service position and you will hear water rushing out
to drain and start to backwash the filter.
18. There should be no media coming out of the drain line, but the water will be black or dirty looking.
At this point the Terminator iron filter will be in a backwash mode, which is the first of two cycles it
goes through during backwash (also called regeneration"). The backwash takes 10 to 12 minutes.
The next cycle is the rinse which takes 6 minutes.
19. After the backwash and rinse cycles are complete, repeat the process and backwash a second time.
20. 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. 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 media and prevent it from cementing together.
21. There should be no Terminator media coming out of the drain line, but the water will be black or dirty
looking. At this point the Terminator iron 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 2510 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 Terminator iron filter at first to prevent
some Terminator 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
