General Information - STA-RITE System 2 PLD50 Installation, Operation & Parts

When to Clean the Filter
The filter module should normally be
cleaned when the pressure gauge read-
ing 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 cleaners may be no-
ticeably 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.
WARNING
Risk of drowning and
falls. Place equipment
at least 4 feet from pool
so that children cannot
climb over it into pool.
Do not allow children sss
to stand or play on filter
or pump.

GENERAL INFORMATION

• Clean a new pool as well as possible before filling pool and operating fil-
ter. 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 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
properly at top of module before operating filter.
• Make sure that Posi-Lok™ Ring is securely locked in place before operat-
ing 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 in-
tervals.
• 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).
