GENERAL
INFORMATION
• Clean a new pool as well as possible before filling pool
and operating filter. Excess dirt and large particles of
foreign matter in the system can cause serious damage
to the filter and pump.
• With a modular Diatomaceous Earth (DE) filter in place
and operating correctly, clean water is returned to the
pool faster than pool water is being contaminated. A
typical pool installation will require approximately one
week to obtain and maintain the sparkle that your filter
is capable of giving you.
• Do not use more than the recommended amount of DE
in your filter. Excess DE can cause a buildup of DE and
“bridging” between the pleats which will plug the filter.
• Maximum pressure is 50 PSI (345 kPa). DO NOT con-
nect the filter to a city water system or to an individual
water well system.
Hazardous pressure. Open air release
valve to vent all air from system before operating
system. NEVER operate filter with air trapped inside.
• The Sta-Rite modular DE filter is designed to filter
water for swimming pools and spas. On a new pool
installation, we recommend:
1.Disassemble the filter after the initial cleanup.
Hazardous pressure. To prevent severe in-
jury or major property damage, exactly follow "Filter
Disassembly/Assembly Procedure" on Pages 6 and 7.
2.Remove and hose down the element assembly to re-
move spent DE and contaminants.
• Maintain pool water pH between 7.2 and 7.6.
• Make sure that internal air bleed tube and filter are
clean and installed properly at top of module before
operating filter.
• Make sure that Posi-Lok™ Ring is securely locked in
place before operating filter.
• Maintain pressure gauge in good working order.
Replace a damaged gauge immediately.
• Cleaning interval is based on pressure rise, not on
length of time filter is operated. Different water condi-
tions will have different normal cleaning intervals.
• Check local codes for restrictions on waste water and
DE disposal requirements.
NOTICE: Some pool disinfectants may clog filter mod-
ule. To maximize module life and filter cycle time,
closely follow disinfectant manufacturer’s instructions
when cleaning pool or filter (see Page 7).

Pressure Gauge Reading at Startup____________________
When to Clean the Filter
The filter module should normally be cleaned when the
pressure gauge reading increases 10 PSI over the start-up
pressure (record the start-up pressure under “Owner’s
Information”, below, right).
In some pools, accessories such as fountains or pool clean-
ers may be noticeably affected by the normal decrease in
flow as the filter becomes dirty. If so, clean the filter more
frequently (that is, at a pressure increase of less than 10
PSI) in order to maintain the required flow.
