GENERAL INFORMATION
Your Hayward ProGrid
TM
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.

INSTALLATION
WARNING
Only simple tools (screwdriver and wrenches), plus pipe sealant for
plastic adapters, are required to install and/or service the filter.
1. The filter system should be installed on a
level concrete slab or
other rigid base. Select a well drained and vented area, one that does
not flood when it rains. Position the filter so that the piping
connections, and winter drain are convenient and accessible for
operation, service, maintenance and winterizing.
2. Position filter so the filter will drain by gravity.
3. If practical, place pump and filter in the shade to shield it from
continuous, direct heat from the sun.
4. Assemble appropriate Filter Control valve (See Page 10 for
selection) to filter. Lubricate the O-ring first (we recommend using
Jack’s 327 Lubricant). Align the two (2) valve pipe connections, with
O-rings in place, with the two openings in the side of the filter tank
and press in firmly. Secure the assembly to the tank connections with
the two bulkhead lock nuts. Do not over-tighten.
5. Connect the pool suction plumbing between the skimmer, pool
outlet and the pump.
6. Install the pool return plumbing.
7. If pressure gauge is not installed, apply Teflon tape to the gauge
threads and carefully screw the gauge into the gauge adapter
assembly.
8. Do not locate pump controls over or near filter.
9. Verify water discharge from the filter manual air relief valve is
directed away from electrical devices
