Swimming Pool Filter User Manual

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 seri-
ous damage to the filter and pump.
• With a modular Diatomaceous Earth (DE) filter in place and operating cor-
rectly, 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 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.
On a new pool installation, we recommend:
1.Disassemble the filter after the initial cleanup.
Hazardous pressure. To prevent severe injury or major prop-
erty damage, exactly follow "Filter Disassembly/Assembly Procedure" on
Pages 6 and 7.
2.Remove and hose down the element assembly to remove 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 prop-
erly 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 op-
erated. Different water conditions will have different normal cleaning inter-
vals.
• Check local codes for restrictions on waste water and DE disposal require-
ments.
NOTICE: Some pool disinfectants may clog filter module. To maximize
module life and filter cycle time, closely follow disinfectant manufacturer’s
instructions when cleaning pool or filter (see Page 8).

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 foun-
tains or pool cleaners may be noticeably
affected by the normal decrease in flow as
the filter becomes dirty. If so, clean the fil-
ter more frequently (that is, at a pressure
increase of less than 10 PSI) in order to
maintain the required flow.
