GENERAL
INFORMATION
Clean a new pool as well as possible before filling pool
and operating filter. Excess dirt and large particles of for-
eign 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 typi-
cal pool installation will require approximately one week
to obtain and maintain the sparkle that your filter is capa-
ble 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 30 PSI (207 kPa). DO NOT connect
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
injury or major property damage, exactly follow "Filter
Disassembly/Assembly Procedure" on Pages 6 and 7.
2. Remove and hose down the filter module to remove
spent DE and contaminants.
Maintain pool water pH between 7.2 and 7.6.
Make sure that Posi-Ring
TM
is securely locked in place be-
fore 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 conditions 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 module.
To maximize filter 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).
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.
