Reinstalling Cartridge Element
Clean any collected debris from the bottom of the
filter housing.
Reinstall cartridge in filter housing. Be sure O-ring is
in place on threads.
Clean O-ring. For ease of future disassembly, apply a
very light film of a dilute solution of non-granulated
liquid-type soap to O-ring and threads.
Screw filter housing with O-ring into filter head. Do
not overtighten. Tighten drain valve and top air relief
valve.
Secure to system with union nut.
Proceed as in Starting the Filter.
Cleaning Cartridge
The cartridge filter element can be cleaned by pressure
washing inside and out with a garden hose. Rotate
cartridge, hosing from top down. (The cartridge is easier
to clean when dry). After hosing the cartridge, for best
results, allow cartridge to dry and carefully brush
pleated surface areas to remove fine particles.
Algae, suntan oil and body oils can form a coating on the
cartridge pleats which may not be thoroughly removed by
hosing. To remove such materials, soak the cartridge in a
solution of filter element cleaner (various brands available
at pool dealer). Follow manufacturer’s directions for use
and allow an hour for soaking. Hose thoroughly before
reinstalling in filter.
If calcium or mineral deposits are excessive, the cartridge
may be restored to “like new” condition by soaking in
muriatic acid. Use commercially available 20% muriatic
acid added to water in 1 to 1 ratio. Use a plastic container
and take extreme care when handling cleaning agents as
they can be harmful to eyes, skin and clothing. After
cleaning, flush with water.
VACUUMING
Vacuuming can be performed directly into the filter
whenever needed. Clean cartridge after vacuuming, if
required.
WINTERIZING
In areas where sub-freezing temperatures can be
expected, the filter should be drained and/or removed
from its operating location and stored indoors. Remove
and clean cartridge. Reinstall cartridge in filter tank.
Tighten cover only a few turns when storing.

ALGAE CONTROL
Algae is a form of plant life which can vary in size from a
few thousandths of an inch to the size of a small tree. Of
the many forms of algae, those most frequently found in
swimming pool water are microscopic in size and green in
color.
Algae readily grows in sunlight and can, under favorable
conditions, quickly overgrow a swimming pool turning it
completely green in just a few hours. On the other hand,
swimming pool water can be kept unfavorable to algae
growth simply by maintaining a chlorine level of at least
1.0 ppm in the water at all times. The chlorine level
should be checked at least once a day using a suitable test
kit.
If an algae condition develops and the pool water
“blooms” green, superchlorination of the pool will be
necessary to clear it. Add unstabilized granular chlorine,
or liquid chlorine. Follow chemical manufacturer’s
recommendation for superchlorination. The algae will
quickly become inactive and can then be removed by the
filter. Live algae, on the other hand, multiplies so fast,
that the filter cannot keep up with its growth rate.
When correctly used, commercial algaecides are effective
against algae, though algaecides should be used in
conjunction with, and not as a substitute for, regular
chlorination or superchlorination.
Maintaining a chlorine level of at least 1.0 ppm in the
pool water at all times is the most effective way to
prevent algae growth in swimming pools.
