SEVERE PERSONAL INJURY OR DEATH.

CAUTION To reduce risk of injury, do not permit children to use or climb on this product. Closely

supervise children at all times. The ANSI/APSP-4 Standard (above-ground and on-ground pools)
advises that components such as the filtration system, pumps, and heaters be positioned to prevent
their being used as a means of access to the pool by young children

WARNING COMPONENT SEPARATION HAZARD

Pool and spa water circulation systems operate under hazardous pressure during start up, normal
operation, and possibly after pump shut off. Pressure in system can cause explosive component
separation of the upper filter body if safety and operation instructions are not followed. Severe
personal injury or death can result.

This product should be installed and serviced only by a qualified pool professional.

FAILURE TO FOLLOW SAFETY AND OPERATION INSTRUCTIONS CAN RESULT IN

.

TO AVOID COMPONENT SEPARATION

•

Follow all safety and operation instructions.

•

Do not operate water circulation system if a system component is assembled improperly, damaged,

missing, or not a genuine Hayward component.

• Before performing maintenance on the water circulation system, verify all system and pump controls
are in OFF position and filter manual air relief valve is in the OPEN position.

• Always tighten nut until spring coils touch each other, never only hand tighten.

• Before starting the system pump, verify that all system valves are set in a position to allow water from

the filter to return back to the pool.

• Before starting the system pump, the manual air relief valve must be in the OPEN position.

• When starting pump, do not stand over or near filter.

• Return to filter to close manual air relief valve only when a steady stream of water (Not air or air and

water mix) is discharged from the manual air relief valve.

WARNING EXCESS PRESSURE HAZARD

Pressure testing of the pump and filter system in excess of the 45 PSI can cause explosive separation of
the components. Component separation can result in severe personal injury or death.

WARNING ELECTROCUTION HAZARD

High Voltage electricity is present in the pool and spa equipment. High voltage electricity can cause shock
and electrocution. Shock and electrocution can result in severe personal injury or death.

• All electrical wiring MUST be in conformance with applicable local codes, regulations and the National
Electrical Code (NEC).

• Before performing any service or maintenance on electrical equipment turn off all electrical power.

• Contact a licensed electrician or building inspector for information on local electrical codes for bonding

requirements.

• Verify water discharge from the filter manual air relief valve is directed away from electrical devices.

Do not locate pump controls over or near filter.

WARNING – SUCTION ENTRAPMENT HAZARD.

Suction in suction outlets and/or suction outlet covers that are, damaged, broken, cracked, missing, or
unsecured can cause severe injury and/or death due to the following entrapment hazards:

Hair Entrapment- Hair can become entangled in suction outlet cover.
Limb Entrapment- A limb inserted into an opening of a suction outlet sump or suction outlet cover that
is damaged, broken, cracked, missing, or not securely attached can result in a mechanical bind or
swelling of the limb.
Body Suction Entrapment- A negative pressure applied to a large portion of the body or limbs can
result in an entrapment.
Evisceration/ Disembowelment Entrapment- A negative pressure applied directly to the intestines
through an unprotected suction outlet sump or suction outlet cover that is, damaged, broken, cracked,
missing, or unsecured can result in evisceration/ disembowelment entrapment.
Mechanical Entrapment- There is potential for jewelry, swimsuit, hair decorations, finger, toe or
knuckle to be caught in an opening of a suction outlet cover resulting in mechanical entrapment.

TO REDUCE THE RISK OF ENTRAPMENT HAZARDS:

• A minimum of two functioning suction outlets per pump must be installed. Suction outlets in the
same plane (i.e. floor or wall), must be installed a minimum of three feet (3’) [1 meter] apart, as
measured from near point to near point.

• Dual suction outlets shall be placed in such locations and distances to avoid “dual blockage” by a
user.

• Dual suction outlets shall not be located on seating areas or on the backrest for such seating areas.

• The pool or spa circulation system shall be designed to comply with ANSI/APSP-7 2006.

• Suction outlet covers shall conform to ANSI/ASME A112.19.8

• Never use Pool or Spa if any suction outlet component (cover/grate) is damaged, broken, cracked,

missing, or not securely attached.

• Immediately replace damaged, broken, cracked, missing, or not securely attached suction outlet
components.

• The CPSP as well as the ICC
specifies the installation of a safety vacuum release system conforming to ASME A112.19.17, or an
approved gravity drain system.

• Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the
suction outlets can result in an increased potential for suction entrapment.

International Residential Code

Part IX, Appendix G, Section AG106

• Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other

material can result in an increased potential for suction entrapment.

Suction outlet covers and grates have a finite life. They should be inspected frequently and
replaced within specified life.

KEEP SAFETY LABELS IN GOOD CONDITION AND REPLACE IF MISSING OR DAMAGED.

PERFLEX

™ Filtration Series IS50C REV C

The Hayward-Perflex is a high performance swimming pool filter with a filtration rating of 3,000 gallons (11 KL) per hour.
Manufactured from durable, corrosion-proof materials, it is designed for continuous operation, for installation above or below, the
pool water line. It may be used on fresh or salt water swimming pools.
The Perflex filter uses diatomite filter powder (commonly called D.E.). D.E. is the most efficient dirt remover known. It is normally fed
into the system through the skimmer when the filter is initially started; then drained from the filter when it can no longer efficiently
remove dirt from the water. Through the Perflex's exclusive "BUMP" action, the D.E. is periodically regenerated and the filter cycle
extended without changing the powder. When the filter powder is totally used, the "BUMP" action makes it possible to drain the used
diatomite without backwashing or dismantling the filter. The EC-50AC is equipped with a special, polished stainless steel clamp,
designed for easy access to the internals of the filter.

PUMP SELECTION

To power your Perflex filter, select a continuous duty
pump designed for swimming pool service. The filter may
be used with a variety of Hayward bases and plumbing
connections, or may be mounted on other suitable
surfaces.

It is important to determine whether the pump will be
located above or below the normal pool water line. If the
pump is going above the water line, a self-priming
centrifugal pump must be used. Self-priming pumps can
lift water from a lower level
and prime automatically.
There is another type of
pump simply called the
centrifugal. Unlike self­priming centrifugals which
can lift water from a lower
level, a centrifugal must be
located below the water
line for dependable

priming.

Select a pump with an output rating of between 30 and
65 GPM (114-246 LPM). Since 50 GPM (189 LPM) is the
desired maximum filter flow, a flow controller (part
number ECX1055) is furnished with each unit for use
with pumps rated between 40 and 65 GPM (150-246
LPM). Install the flow controller in the filter body as
illustrated with an elbow adapter, union connector, or
adapter. The adapter both secures the controller in its
proper position, and completes the hydraulic balance
of the system.

PLUMBING & INSTALLATION

1. To facilitate servicing of the filter system and to allow
for indoor storage during the winter months, installing
union connections at the suction and outlet ports is
recommended.

2. Use 1-1/4" or 1-1/2" I.D. flexible plastic pipe, or hose,
joined with insert fittings and stainless steel clamps.

3. All plumbing connections on the system are 1-1/2"

FILTER LOCATION

1. Though the filter 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. Locate the filter as close to the pool
as practical, keeping the number of fittings to a
minimum.

2. Set the filter on a level mounting platform or base. Keep
the filter bump handle, drain outlet, and pressure gauge
accessible for convenient operation.

3. Position the system so that the filter tank can drain by
gravity.

N.P.T. When making connections, use plastic male-end
adapters. Apply three turns of Teflon tape or plastic
pipe sealant compatible with ABS to the male threads.
Screw the fitting into the thread hand tight; then, using
a wrench, tighten one more full turn. Additional
tightening is unnecessary-and-could result in damage
to components.

4. Refer to the diagrams for suggested valving. Ball-type
valves are recommended where needed.

™ Filtration Series IS50C REV C

5. Tighten pump base mounting bolts, if loose.

6. Securely
and pump.

7. Connect the pool suction plumbing between the
skimmer, pool outlet, and the pump.

8. Connect the pool return (inlet) plumbing

9. If the pressure gauge is not installed, apply Teflon
tape to the gauge threads, and
gauge into the threaded hole in the side of the filter
body.

10. A filter drain plug, with gasket, is furnished with
each filter and is all that is needed for complete
filter draining. If desired however, drain piping may
be extended from the filter by using the optional
Drain Valve Kit (Model SP0723) and an appropriate
length of 1-1/2" pipe. Piping must slope away from
the filter so the tank can drain by gravity.

11. All electrical connections should be made in
accordance with applicable electrical codes.

12. Check for joint leaks before operating system.

13. Refer to pump instruction booklet for pump
information.

BEFORE STARTING THE FILTER

1. Obtain a supply of operating chemicals, D.E., and a
pool test kit. Use only the swimming pool grades of
D.E., such as:

CELATOM Eagle-Picher Industries, Inc.
AQUA-CEL Johns-Manville Products

DICALITE 4200 Grefco Inc.
WITCO Witco Corporation

2. 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.

INITIAL SET-UP

1. Always turn off pump and relieve tank pressure by
opening Air Relief Valve before loosening Center
Clamp or servicing filter.

WARNING-SEPARATION HAZARD

Tighten nut until spring coils touch each other.

2. To re-assemble Clamp on filter, 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.

The end of the T-bolt must extend through the
trunnion, slide a (1) Washer ECX500J4 over the end of
the T-Bolt followed by the (2) Spring ECX500JS, then
the (3) Washer ECX500J3. (4) Thread the Nut ECX360JN
onto the end of the T-Bold.

Tighten the nut with a using a wrench and 9/16”
socket until the spring coils all touch and then an
additional 2 turns.

3. To re-start system, open all in-line valves. Open Air

Relief Valve before starting pump. Stand clear of filter
and prime and start the pump per the manufacturer's
instructions. When a steady stream of water emerges
from the Air relief Valve, close Air Relief Valve.

STARTING THE FILTER

Close the filter drain and the vent valve.

PERFLEX

CAUTION All suction and

discharge valves must be open
when starting the pump. Failure to
do so could cause severe personal
injury and/or property damage.

Prime and start the pump following the manufacturer's
instructions. Air trapped in the system will automatically
vent to the pool. When there is a steady flow of water
returning to the pool, the filter is ready for precoating.

DO NOT

without the precoat charge.

operate the filter for more than one minute

™ Filtration Series IS50C REV C

PRECOATING

Scoop 5 lbs. (2.3 kgs.) of diatomite into the system
through the skimmer as fast as the plumbing will take it.
Note and record the pressure gauge reading after the
diatomite has been added. This is the

"precoat

pressure."

FILTERING

Filtration starts as soon as the filter has been precoated.
As the filter 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-.70 Bar)
above the precoat pressure, regenerate the filter.

REGENERATION (Extending the Cycle)

Stop the pump. Move the bump handle down slowly,
then up briskly. Repeat 3 times. Restart the pump and
filtration will resume at near the original flow and
pressure.
After each regeneration, and until the filter is cleaned,
there may be a slight increase in the starting pressure.
This is the result of dirt accumulating within the filter and
is completely normal.

CLEANING

Cleaning is recommended when the gauge pressure
rises more than 10 psi (.70 Bar) in less than a 24 hour
period or when cloudy water returns to the pool for more
than 30 seconds after regeneration. To clean, first stop
the pump; then move the bump handle down slowly,
then up briskly. Repeat 8 times. Open the vent valve
(under bump cover), open the filter drain (Note: if the
filter is installed below the pool water line, close the
suction and return valves) and allow water and-dirt-to­empty completely.

After the filter has drained, and with the drain still open,
run the pump for a few seconds to flush out any dirt
remaining in the bottom of the filter. (Note: If the filter is
installed below the pool water line, opening the
valve for a few seconds with the pump off will
adequately flush the unit.)

Close the filter drain and the vent valve. Open the
suction and return valves (when used). Start the pump
and let the filter fill with water and repeat the CLEANING
procedure. This completes the cleaning phase. The filter
is now ready for recharging. Proceed as in STARTING THE
FILTER and PRECOATING.

suction

VACUUMING

Vacuuming can be performed directly into the filter
whenever needed. For fastest results, regenerate the
filter before and after each vacuuming operation.

TO CHANGE BUMP HANDLE POSITION

1. Remove the bump handle grip. Push in tab at
base of handle. Carefully pry the bump cover
from the retaining groove and slide the cover off
the handle.

2. Using a drift (or 10 penny nail), tap the pivot pin

out of the filter head anchor point, freeing the
end of the handle.

3. Rotate the bump handle to the alternate position
and align the handle and the head anchor holes.
Tap the pivot pin in place.

4. Reinstall the bump cover and grip.

GAUGE/INSPECTION PORT ADAPTER

The gauge/inspection port adapter provides an easy way
to look into the filter, at the top area of the tube nest
assembly. It gives a quick inspection capability to check
tube nest conditions (algae, calcium or D.E. build-up, ect.)
without requiring the removal of the filter head. It also
allows you to wash off trapped debris and excess D.E.
from between the Flex-Tubes; and from under the tube
sheet, by spraying with a garden hose, or utilizing
Hayward’s Jet-Action Cleaning Wand (EC2024) that
attaches to the end of a garden hose.

To remove adapter- shut off the pump and valves. Open
the air relief. Drain the water in the filter to a level below
the adapter port. Unscrew the adapter, with the pressure
gauge, counterclockwise.

To Reinstall the adapter - thread the adapter, with the
adapter o-ring in place, securely into the filter housing.

PREVENTIVE MAINTENANCE

While Perflex filters are basically resistant to the
difficulties often encountered as a result of chemical
build-up in swimming pools, it is important to keep in
mind that the mineral content in a pool increases every
day as a result of the chemicals and the normal water
evaporation process. If the concentration of minerals is
allowed to get too high, the minerals will form deposits on
the Flex-Tubes inside the filter, and will eventually result
in shortened filter cycles.

The filter elements can be cleaned by washing with a
garden hose. For best results, carefully brush the surface
to remove fine particles. Do Not Pressure wash as it can
damage the filter elements.

You may find some debris on the filter elements , which
may not be removed with hosing.

After cleaning, thoroughly flush all affected parts with
cold water.

WINTERIZING

In areas where sub-freezing temperatures can be
expected, the filter should be drained and removed from
its operating location and stored indoors. Prior to

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

0.5 ppm in the water at all times. The chlorine level

SUGGESTED POOL CHEMISTRY LEVELS

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. In an active algae situation, it
may be necessary to regenerate the Perflex filter as
frequently as every 2 to 3 hours.

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.
