Pressure wash cartridge inside and
out with Hayward’s Jet-Action
Cleaning Wand (EC2024) or a
garden hose.
Allow to dry and brush pleated
surface areas.
To remove algae, suntan oil and
body oils, soak for one hour in a
solution of filter element cleaner.
(See your local pool dealer)
To remove calcium or mineral
deposits, soak in muriatic acid
solution. *Caution: Use a plastic
container and take extreme
care—harmful to eyes, skin and
clothing.
After cleaning, flush with water.

K. VACUUMING
Vacuuming can be performed directly into the filter whenever needed.
For fastest results, clean the filter before and after each vacuuming
period. For heavy spring clean-ups, we recommend using a Hayward
SPO727 diverter valve to bypass the filter and accelerate the clean-up
process. Consult your local Hayward dealer for a detailed explanation.
L. 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. Clean the element at the end of the pool season by using your
garden hose with a high pressure nozzle or the Hayward EC2024
Jet-Action Cleaning Wand. You will then be prepared to enjoy your pool
the next spring.
Consult your local authorized Hayward dealer or service center. No
returns may be made directly to the factory without the expressed
written authorization of Hayward Pool Products, Inc.
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 free 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 free 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.
