IMPORTANT SAFETY INSTRUCTIONS.
READ AND FOLLOW ALL INSTRUCTIONS.
When installing and using this equipment, basic safety precautions
must always be followed. This filter operates under high pressure.
Failure to follow instructions may result in serious injury.
REMOVE CLAMP TAPE. DO NOT LEAVE TAPE EXPOSED TO SUN.
MAKE SURE CLAMP IS LOCATED AND CENTERED PROPERLY
OVER THE FILTER FLANGE.
BOTH SIDES OF THE CLAMP MUST BE TIGHTENED FIRMLY AND
EVENLY UNTIL SPRING COILS TOUCH EACH OTHER (SEE
ILLUSTRATION BELOW).
FINAL SPACE BETWEEN BOTH
CLAMP HALVES SHOULD BE
EQUAL.
CAUTION: All suction and discharge valves must be open when starting
the system. Failure to do so could result in severe personal injury and/or
property damage.
The following clamp spring assembly, which includes a spring, two
washers (small and large hole) and a sleeve nut, provides a
visual means of ensuring that the clamp is tight.
STARTING THE FILTER
BE SURE CENTER CLAMP IS SECURE. Be sure filter drain plug
is closed. Open Air Relief Valve at top of filter a few turns. Open
suction and return valves (when used). Stand clear of filter and
prime and start the pump, following the manufacturer’s
instructions. Air trapped in the system will automatically vent to the
pool and out the Air Relief Valve. Close Air Relief Valve when a
steady stream of water emerges.
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 cartridges.
CLEAN/REPLACE CARTRIDGES
Removing Cartridge Elements
Shut off the pump.
If filter is located below water level, close valves (or block off
suction and discharge lines) to prevent backflow of water from
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 turns.)
Disassembly:
Using a 9/16
”
wrench, alternately loosen both clamp
sleeve nuts. Remove one clamp sleeve nut assembly
(spring, two washers and sleeve nut) and carefully remove
clamp.
To remove Filter Head, tap it on the side to break seal at
center of tank OR insert a blunt screwdriver into one of the
notches located behind Connector Fittings, or 90˚ to the
left
of the Connector Fittings, and twist to lift filter head
slightly. DO NOT grasp gauge assembly when removing
filter head—breakage will result.
To Remove Cartridges:
Lift off top closure plate.
Remove cartridges from bottom collector manifold by using
a slight rocking motion and lifting up.
Clean cartridge. (see Cleaning Cartridges)
Reinstalling Cartridges
Flush and drain any dirt or debris from the bottom of the filter
tank.
Carefully replace cartridges over hubs on bottom manifold.
Place top closure plate securely into top of cartridges.
Clean and lightly lubricate Tank O-ring and carefully place
over Filter Body lip.
Clean Filter Head flange sealing surface, and place over Tank
O-ring, pressing down firmly and evenly to seat the Filter
Head in place.
Replace Clamp Assembly. Make sure clamp is located and
centered properly over the filter flange. If Clamp is tight, tap
Clamp with rubber mallet or block of wood to help seat it.
Insert threaded stud through retainer and secure with Clamp
Spring Assembly (be sure to position small and large hole
washers properly—see illustration in IMPORTANT SAFETY
INSTRUCTIONS).
In some cases it may be necessary to use the two-part filter
clamp to assist in assembling the filter cover to the filter base.
With one nut, spring and washer assembly already removed,
loosen the remaining clamp nut to maximize clamp opening. If
Clamp is tight, tap Clamp with rubber mallet or block of wood
to help seat it as you are tightening nuts. If the two (2) clamp
springs (DE2400JS) are temporarily removed in order to fully
extend the clamp bolts, the clamp springs and washers MUST
be reassembled as shown in the CLAMP SPRING ASSEMBLY
diagram in IMPORTANT SAFETY INSTRUCTIONS.
Tighten sleeve nuts alternately to secure Clamp firmly and
evenly to form a good seal (be sure spring coils touch each
other and final space between Clamp halves is even—see
illustration in IMPORTANT SAFETY INSTRUCTIONS).
Install Drain Plug, open pool suction and return valves and
proceed as in STARTING THE FILTER.
Cleaning Cartridges
The cartridge filter element can be cleaned by pressure washing
inside and out with a garden hose. (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 are available at pool dealer). Follow
manufacturer’s directions for use and allow an hour for soaking.
Hose thoroughly before reinstalling the 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.
A spare 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 cartridges are specifically designed and engineered for
use in Star-Clear filters. For best results, use only genuine
Hayward Star-Clear cartridges in your filter. Order
Model No.
CX470XRE, CX570XRE, CX870XRE or CX1260RE from your
dealer. The Hayward name is your guarantee of quality.
VACUUMING
Vacuuming can be performed directly into the filter whenever
needed. Clean cartridges after vacuuming, if required.
