Installation - Hayward ProGrid DE2420 Owner's Manual

GENERAL INFORMATION
TM
Your Hayward ProGrid Vertical Grid D.E. Filter combines superior water filtration with ease of operation and totally corrosion-
free construction. It uses diatomaceous earth (D.E.), which is the most efficient dirt remover and filter medium known.
The D.E., which is usually fed through the skimmer at initial start-up, uniformly coats the curved vertical filter elements that are
covered with a custom fitted monofilament polypropylene filter cloth. As pool water is pumped through the control valve into
the bottom of the filter tank, the D.E. surface, or coating, filters out even the minutest particles resulting in clear, clean, sparkling
water.
After a period of time, the accumulated dirt in the filter causes a resistance to flow, the pressure rises, and flow diminishes. This
means the dirt holding capacity of the D.E. has been reached, and it is time to clean (backwash) your filter. With the control
valve in the back wash position, the water is automatically reversed through the filter, flushing trapped dirt, debris and D.E. out
the waste line. Once the filter is backwashed (cleaned) of D.E. and dirt, the control valve is manually re-sequenced to filter
position and a fresh charge of D.E. is added to resume normal filtering.
