Step 11

Determination of backwash frequency will vary by media used, the

amount of water used and the amount of contaminant in the wa-

ter. Most media should backwash once every four days in Backwash

Filtration Systems containing activated carbon. If pressure drops

become undesirable or the contaminant reappears, increase the fre-

quency to correct. For media tanks containing Calcite or Corosex, the

frequency should be once every other day to help prevent cementing

of the media in the media tank. Correct backwashing frequency as

required. Tank should be marked for easier maintenance.

Step 12

If your CBF Series Residential Backwash Filtration System contains

Activated Carbon or Filter Sand proper saturation time is critical. Re-

fer to Figure 5 to determine the proper saturation time for that media

type.

Step 13

Turn on the electrical power to the well pump or open the valve on the municipal supply and pressurize the water line and check for leaks, correct as

required. Locate the regeneration button on the control valve and initiate a manual regeneration (see “HOW TO MANUALLY INITIATE IMMEDIATE REGEN-

ERATION”), ensure the bypass valve is in the bypass position. Once the control valve stops in the ﬁ rst position, unplug control valve so the valve will not

stage to another position to ensure proper start up and media classiﬁ cation. Open the INLET side of bypass 1/4 turn to allow water to run slowly to the

waste drain until no air is heard in the drain line. Then slowly open the inlet side of bypass fully and let run until the waste water is clear, it should take

about 10 minutes. Then open the OUTLET side of the bypass into the fully open position. During the initial backwash cycle it is normal for a small amount

of “ﬁ nes” to appear at the drain for proper preparation of media bed. It will subside within a few regeneration cycles and should not alarm you.

Step 14

Plug the control valve into the 120v 60Hz power source once again and ensure the time clock is properly set for time and frequency of regeneration. The

control valve will stage by itself and back to the service position.

Installation is complete and system is ready for use.

IMPORTANT NOTES

Flush at least 10 gallons (37.9 liters) through this system during installation. It may be necessary to continue ﬂ ushing beyond 10 gal-

lons until the water is clear.
