1) If your unit contains activated carbon, you should replace the carbon and gravel underbed at least
every three years. Replacement may be required sooner if the taste and odor being removed begins to
reappear in the treated water or you experience increasing pressure drop that is not resolved by
increasing the frequency of backwashing.
2) Filter Ag and Filter Sand will last indefinitely. It may be necessary to replace them if you experience
increasing pressure drop that is not resolved by increasing the frequency of backwashing or if water
quality diminishes due to contaminant bleed through.
3) Neutralizer media or calcite must be replenished at least annually. Mark the side of the mineral tank at
installation so the drop in media level may be monitored by shining a bright light behind the mineral
tank. Add media if the level has dropped by more than three inches.
4) Birm should be replaced when iron reappears in the treated water and backwashing does not improve
the water quality.
TO REPLENISH OR REBED MEDIA:
1) Pressure must be relieved on the system by placing the Bypass Valve in the "Bypass" position (Figure
3, Page 5) and initiating a manual regeneration (section 3, page 10).
2) Unplug the Control Valve from the electrical outlet to prevent it from advancing automatically.
3) Disconnect the Control Valve from the Bypass Valve
4) Disconnect the Drain Line from the Control Valve
5) Unscrew Control Valve from Mineral Tank (IF REBEDDING ONLY! Remove the distributor).
6) Siphon water from Mineral Tank (IF REBEDDING ONLY! Remove existing media and gravel).
7) (IF REBEDDING ONLY! Rinse Mineral Tank and replace distributor, making certain that the
distributor basket sits in the center of the tank bottom.)
8) Cover the top of the distributor tube to prevent media entering the tube during filling. Using a funnel,
pour filter media(s) into the mineral tank. (IF REBEDDING ONLY! Begin loading the tank with the
gravel underbed. Filling the Mineral Tank 1/3 with water before loading gravel will cushion the
fall and ensure even distribution of the gravel and media. If using multiple filter media types,
load in the order of heaviest {most dense} to lightest {least dense}.) 12" – 14" of space MUST be
left empty at the top of the mineral tank to allow for media bed expansion during backwash and to
prevent filter media from being discharged through the drain line.
9) (IF REBEDDING ONLY! Use a garden hose or bucket to fill the media tank with water.)
10) Clean mineral tank threads to remove any filter media. Uncover distributor tube and reinstall control
valve by threading it securely onto the mineral tank. (O-ring seal; HAND TIGHTEN ONLY!)
