CLARIFIER FILTER

During service (FIG. 5) water goes into the filter and

DOWN through the bed of mineral. The mineral takes the dirt, sand, silt, clay and other sediments out of the water and holds it in the bed. Clear, clean water goes out of the filter and into the house pipes.

NEUTRALIZER FILTER

As low pH (acid) water flows DOWN through the filter, neutralite mineral is slowly dissolved to raise the pH. The neutralized or non-acid water then flows into the house water pipes. Because the neutralite does dissolve, you have to add new mineral at least once each year, and sometimes more often (see page 14).

Backwash is a reverse or UPWARD fast flow of water

through the filter. The fast, upward flow flushes dirt, sediment, iron, etc., from the mineral bed and to the drain. The bed is lifted and expanded for good

cleaning. The bed is also mixed to remove any

channels water flow may have formed through the mineral.

Following backwash, water again changes direction to flow downward through the bed at a fast rate. The mineral bed is repacked and prepared for return to service.

TASTE AND ODOR FILTER

FILTERED

WATER OUT WATER IN

The taste and odor filter is filled with activated carbon. As water flows into and DOWN through the filter (FIG. 5), the tastes and/or odors are adsorbed and held by the carbon. Water without bad tastes or odors goes into the house pipes.

When the activated carbon no longer takes the tastes and/or odors out of the water, you must replace it (see page 16). The carbon usually lasts for up to 1 year, and sometimes longer. It depends on how much

water you use, and how much taste and/or odor is in the water.
