SYSTEM LOCATION
Though the system is designed for outdoor use, it is
advisable to protect electrical components from the
weather. Select a well-drained area, one that will not
flood when it rains.
For best pump performance, position the system below
the swimming pool water line. If the system must be
located above the pool water line, it can be raised as
high as 2 feet (610 mm) above the water without
affecting the pump’s efficiency.
NOTE: NSPI-4 Article V, standard for above-ground and
on-ground pools, advises that components such as the
filtration system, pumps and heater be positioned so as
to prevent their being used as a means of access to the
pool by young children.
Set the mounting platform level. Keep the cover lock,
filter bump handle, drain outlet and pressure gauge
accessible for convenient operation.
Position the system so the filter tank can be drained by
gravity.
PLUMBING INSTALLATION
Use 1-1/4” or 1-1/2” I.D. flexible plastic pipe, or hose,
joined with insert fittings and stainless steel clamps.
All plumbing connections on the system are 1-1/2”
N.P.T. When making connections, use plastic male-end
adapters. Apply three turns of Teflon tape or plastic
pipe sealant to the male threads. Screw the fitting into
the threads hand tight; then, using a wrench, tighten
one more full turn. Additional tightening is unnecessary
and could result in damaged components.
Refer to the diagrams for suggested valving. Ball-type
valves are recommened where needed.
IS-400-1540-98

Tighten pump base mounting bolts, if loose.
Securely hand tighten the union nut between the
filter and pump.
Connect the pool suction plumbing between the
skimmer, pool outlet and the pump.
Connect the pool return (inlet) plumbing.
If pressure gauge is not installed, apply Teflon tape
to the gauge threads, and carefully screw the
gauge into the threaded hole in the filter cover.
A drain plug is furnished with each filter and is all
that is needed for complete filter draining. A manual
air vent valve is furnished to aid in bleeding off
unwanted air when starting the filter.
All electrical connections should be made in
accordance with local codes.
Check for joint leaks before operating the system.
Refer to pump instruction booklet for pump
information.

BEFORE STARTING THE FILTER
Superchlorinate the pool water by adding unstabilized
granular or liquid chlorine. Stabilized forms of chlorine are
recommended for normal daily use after the initial clean
up of the water. Follow chemical manufacturer’s
recommendations for superchlorination and daily use.
STARTING THE FILTER
Be sure filter drain plug is closed. Open manual air relief
valve a few turns and open the suction and return valves
(when used). CAUTION: All suction and discharge
valves must be open when starting the system. Failure
to do so could cause severe personal injury and/or
property damage. Be sure Easy-Lok lid is secure (hand
tight only).
Prime and start the pump following the manufacturer’s
instructions. Air trapped in the system will automatically vent
to the pool and out vent valve. Close vent valve as soon as
air is vented.
FILTERING
Filtration starts as soon as flow is steady through the filter.
As the filter cartridge removes dirt from the pool water, the
accumulated dirt causes a resistance to flow. As a result,
the gauge pressure will rise and the flow will decrease.
When the pressure rises 7-10 psi (.49-.69 Bar) above the
starting pressure, or when flow decreases below desired
rate, clean or replace the filter cartridge.
CLEAN/REPLACE CARTRIDGE
Removing Cartridge Element
Shut off the pump.
If filter is located below water level, close valves or
block off discharge line to prevent backflow of water
from the pool.
Unscrew and remove drain plug and allow water to
drain from filter. Close drain plug. (Note: To assist
draining process; open air vent a few times.)
Depress safety latch, unscrew and remove Easy-Lok lid
(counterclockwise direction).
Carefully lift off lid to gain access to filter cartridge.
Lift out cartridge and clean. Or, replace with clean,
spare cartridge. (See Cleaning Cartridge)
Reinstalling Cartridge Element
Clean any collected debris from the bottom of filter
body.
Carefully replace cartridge element into filter body
ensuring that the cartridge sits evenly on the collector
hub in bottom of filter body.
Place Easy-Lok lid on filter body and turn clockwise
until it engages and is secured by the safety-latch.
Proceed as in STARTING THE FILTER.
Cleaning Cartridge
The cartridge filter element can be cleaned by pressure
washing inside and out with Hayward’s Jet-Action Cleaning
Wand (EC-2024) or 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.
Aspare cartridge filter element is an excellent investment. It
provides convenience and ensures that your filter will
always be ready to operate at peak efficiency.
Hayward Full-Flo element cartridges are specially designed
and engineered for use in Easy-Clear filters. For best
results, use only genuine Hayward element cartridges in
your filter. Order
Model No. CX410-RE or CX550-RE
from
your dealer. The Hayward name is your guarantee of
quality.
VACUUMING
Vacuuming can be performed directly into the filter
when-ever 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 locking
knob only a few turns when storing.
SERVICE & REPAIRS
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 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 by simply maintaining a chlorine level of at least 0.5
ppm in the water at all times. The chlorine level should be
checked at least once a day using a suitable test kit.
If 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 0.5 ppm in the pool
water at all times is the most effective way to prevent algae
growth in swimming pools.
