Water Pressure
Your water filter is designed to operate under normal water pressures from 20 psi to 125 psi.
Regeneration and Automatic Bypass
Water filters are factory set to regenerate at 1:00 a.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.
Note: When more than one filter is being used, regeneration should be staggered by 15 minute intervals from 1 a.m.
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 unfiltered.
To resume soft water service, open the bypass valve by reversing the rotation of
the knobs counter-clockwise.
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.

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.
