Operating Instructions
Water Pressure
Your water filter is designed to operate under normal water pressures from 20 psi to 100 psi.
Regeneration and Automatic bypass
Water filters are factory set to regenerate at 11:00 p.m. during a period of little or no water use. The regeneration cycle
lasts approximately 15 minutes, after which filtered water service is restored. While regeneration is taking place,”raw
water” automatically bypasses the filter if required. If possible, avoid using water during regeneration to prevent
unfiltered water entering your household plumbing system.
(Installation Tip: The 5600SXT Filter should not be allowed to regenerate at the same time as any other water
treatment units. If adjustment is required, consult programming chart to adjust default regeneration time.)
New Sounds
You will notice new sounds such as the hum of the timer, as your filter operates. During regeneration, it will not be
uncommon to hear water running to the drain.
Manual bypass
In case of an emergency you can isolate your water filter from the water
supply using the bypass valve located at the back of the control.
In normal operation the bypass is open with the ON/OFF knobs in line with
the INLET and OUTLET pipes. To isolate the filter, simply rotate the knobs
clockwise (as indicated by the word BYPASS and arrow) until they lock.
You can use your water related fixtures and appliances as the water supply
is bypassing the filter. However, the water you use will be untreated.
To resume filter water service, open the bypass valve by rotating the knobs
counter-clockwise.
Manual Regeneration Cycle
If you run out of filtered water because of inadequate regeneration frequency, inadequate reserve capacity, power failure
or unusually high water usage, you can initiate a manual regeneration simply by pressing the extra cycle button. The
filter will now automatically complete a regeneration cycle and return to service. If possible, avoid water use during the
regeneration cycle.
Once you have set your filter and you experience frequent loss of water pressure, you may have to increase the
frequency of regeneration by resetting the gallons between regeneration.

Start-Up Instructions
Water-only backwash
1. Check that the correct backwash (BW) flowrate has been determined based on the water temperature. (See table below)
2. Allow the tank to slowly fill with water from the bottom. This is most easily accomplished by setting the control valve to the backwash
position and partially opening the inlet valve until water flows from the drain line.
3. Allow the media to soak for at least 30 minutes.
4. Fully open the inlet valve and set the control valve in the backwash position.
5. Depending on how critical the application is, allow the filter to backwash for 20 to 30 minutes. Continue the backwash until the water
is clear and free of particles. This is backwash #1.
6. Allow the filter to settle for 10 to 15 minutes. Do not allow the control valve to enter the fast rinse cycle.
7. Depending on how critical the application is, allow the filter to backwash again for 15 to 20 minutes. This is backwash #2.
8. Allow the filter to fast rinse (downflow) for 5 to 8 minutes.
9. The filter is now ready for service.
