WARNING - Read and follow all instructions in this owner’s manual and on the equipment. Failure to
follow instructions can cause severe injury and/or death.
WARNING – Suction Entrapment Hazard.
Suction in suction outlets and/or suction outlet covers which 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 - A negative pressure applied directly to the intestines through an unprotected suction outlet
sump or suction outlet cover which is, damaged, broken, cracked, missing, or unsecured can result in evisceration/
disembowelment.
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.
WARNING - To Reduce the risk of Entrapment Hazards:
o When outlets are small enough to be blocked by a person, 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.
o Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
o Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
o The maximum system flow rate shall not exceed the flow rating of as listed on Table 1.
o Never use Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached.
o Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately.
o In addition two or more suction outlets per pump installed in accordance with latest ASME, APSP Standards and CPSC
guidelines, follow all National, State, and Local codes applicable.
o Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.
WARNING – Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa from the
suction outlets can result in an increase potential for suction entrapment as described above.
WARNING – Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper and other
material can result in an increase potential for suction entrapment as described above.
WARNING – Suction outlet components have a finite life, the cover/grate should be inspected frequently and
replaced at least every SEVEN years or if found to be damaged, broken, cracked, missing, or not securely attached.
CAUTION – Components such as the filtration system, pumps and heater must be positioned so as to prevent their
being used as means of access to the pool by young children. To reduce risk of injury, do not permit children to use or climb
on this product. Closely supervise children at all times. Components such as the filtration system, pumps, and heaters must be
positioned to prevent children from using them as a means of access to the pool.
WARNING – Hazardous Pressure. Pool and spa water circulation systems operate under hazardous pressure during
start up, normal operation, and after pump shut off. Stand clear of circulation system equipment during pump start up. Failure to
follow safety and operation instructions could result in violent separation of the pump housing and cover, and/or filter housing
and clamp due to pressure in the system, which could cause property damage, severe personal injury, or death. Before servicing
pool and spa water circulation system, all system and pump controls must be in off position and filter manual air relief valve must
be in open position. Before starting system pump, all system valves must be set in a position to allow system water to return
back to the pool. Do not change filter control valve position while system pump is running. Before starting system pump, fully
open filter manual air relief valve. Do not close filter manual air relief valve until a steady stream of water (not air or air and water)
is discharged.
WARNING – Separation Hazard. Failure to follow safety and operation instructions could result in violent separation of
pump and/or filter components. Strainer cover must be properly secured to pump housing with strainer cover lock ring. Before
servicing pool and spa circulation system, filters manual air relief valve must be in open position. Do not operate pool and spa
circulation system if a system component is not assembled properly, damaged, or missing. Do not operate pool and spa circulation
system unless filter manual air relief valve body is in locked position in filter upper body. Never operate or test the circulation
system at more than 50 PSI. Do not purge the system with compressed air. Purging the system with compressed air can cause
components to explode, with risk of severe injury or death to anyone nearby. Use only a low pressure (below 5 PSI), high volume
blower when air purging the pump, filter, or piping. Use ONLY Hayward clamp system components: DEX2421JKIT clamp assembly,
DEX2421J2 nut/bolt assembly, and a DEX2422Z2 metal reinforced seal. Non-Hayward components may fail in use and cause
explosive separation.
Never rely on hand tightening the clamp nut to the clamp bolt. Using a ¾” socket on a torque wrench, torque clamp nut and clamp
bolt to 150 inch-lbs. Before starting system pump, insure filter manual air relief valve body is in LOCK position in filter upper body.

WARNING – Risk of Electric Shock. All electrical wiring MUST be in conformance with applicable local codes,
regulations, and the National Electric Code (NEC). Hazardous voltage can shock, burn, and cause death or serious property
damage. To reduce the risk of electric shock, do NOT use an extension cord to connect unit to electric supply. Provide a properly
located electrical receptacle. Before working on any electrical equipment, turn off power supply to the equipment. To reduce
the risk of electric shock replace damaged wiring immediately. Locate conduit to prevent abuse from lawn mowers, hedge
trimmers and other equipment. Do NOT ground to a gas supply line.
WARNING – Risk of Electric Shock Failure to ground all electrical equipment can cause serious or fatal electrical shock
hazard. Electrical ground all electrical equipment before connecting to electrical power supply.
WARNING – Risk of Electric Shock Failure to bond all electrical equipment to pool structure will increase risk for
electrocution and could result in injury or death. To reduce the risk of electric shock, see installation instructions and consult a
professional electrician on how to bond all electrical equipment. Also, contact a licensed electrician for information on local
electrical codes for bonding requirements.
Notes to electrician: Use a solid copper conductor, size 8 or larger. Run a continuous wire from external bonding lug to
reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm
pressure wire connector provided on the electrical equipment and to all metal parts of swimming pool, spa, or hot tub, and metal
piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of swimming pool, spa, or hot tub.
IMPORTANT - Reference NEC codes for all wiring standards including, but not limited to, grounding, bonding and other general
wiring procedures.

WARNING – Risk of Electric Shock . The electrical equipment must be connected only to a supply circuit that is
protected by a ground-fault circuit-interrupter (GFCI). Such a GFCI should be provided by the installer and should be tested on a
routine basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push reset button. Power should be
restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power to the electrical equipment
without the test button being pushed, a ground current is flowing, indicating the possibility of an electrical shock. Do not use this
electrical equipment. Disconnect the electrical equipment and have the problem corrected by a qualified service representative
before using.

spas if so marked. Do not use with storable pools. A permanently-installed pool is constructed in or on the ground or in a
building such that it cannot be readily disassembled for storage. A storable pool is constructed so that it is capable of being
readily disassembled for storage and reassembled to its original integrity.

WARNING – Risk of Hyperthermia. To avoid hyperthermia the following “Safety Rules for Hot Tubs” are recommended by
the U.S. Consumer Product Safety Commission.
1. Spa or hot tub water temperatures should never exceed 104°F [40°C]. A temperature of 100°F [38°C] is
considered safe for a healthy adult. Special caution is suggested for young children. Prolonged immersion in
hot water can induce hyperthermia.
2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness, which
could lead to unconsciousness and subsequently result in drowning.
3. Pregnant women beware! Soaking in water above 100°F [38°C] can cause fetal damage during the
first three months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant women
should adhere to the 100°F [38°C] maximum rule.
4. Before entering the spa or hot tub, users should check the water temperature with an accurate ther-
mometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).
5. Persons taking medications, which induce drowsiness, such as tranquilizers, antihistamines or anti-
coagulants, should not use spas or hot tubs.
6. If the pool/spa is used for therapy, it should be done with the advice of a physician. Always stir pool/ spa
water before entering the pool/spa to mix in any hot surface layer of water that might exceed healthful
temperature limits and cause injury. Do not tamper with controls, because scalding can result if safety controls
are not in proper working order.
7. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure
problems should obtain a physicians advice before using spas or hot tubs.
8. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above
normal body temperature of 98.6°F [37°C]. The symptoms of Hyperthermia include: drowsiness, lethargy,
dizziness, fainting, and an increase in the internal temperature of the body.
The effects of Hyperthermia include:
1. Unawareness of impending danger.
2. Failure to perceive heat.
3. Failure to recognize the need to leave the spa.
4. Physical inability to exit the spa.
5. Fetal damage in pregnant women.
6. Unconsciousness resulting in danger of drowning.

GENERAL INFORMATION
Your Hayward D.E. Filter combines superior water filtration with ease of operation and totally corrosion-free construction. It
uses diatomaceous earth (D.E.), which is the most efficient dirt remover and filter medium known.
The D.E., which is usually fed through the skimmer at initial start-up, uniformly coats the filter elements that are covered with a
custom fitted monofilament polypropylene filter cloth. As pool water is pumped through the control valve into the bottom of the
filter tank, the D.E. surface, or coating, filters out even the minutest particles resulting in clear, clean, sparkling water.
After a period of time, the accumulated dirt in the filter causes a resistance to flow, the pressure rises, and flow diminishes. This
means the dirt holding capacity of the D.E. has been reached, and it is time to clean (backwash) your filter. With the control valve
in the back wash position, the water is automatically reversed through the filter, flushing trapped dirt, debris and D.E. out the
waste line. Once the filter is backwashed (cleaned) of D.E. and dirt, the control valve is manually re-sequenced to filter position
and a fresh charge of D.E. is added to resume normal filtering.

INSTALLATION
WARNING
9. Verify water discharge from the filter manual air relief valve is directed away from electrical devices
qualified professional.
Only simple tools (screwdriver and wrenches), plus pipe sealant for
plastic adapters, are required to install and/or service the filter.
1. The filter system should be installed on a level concrete slab or
other rigid base. Select a well drained and vented area, one that does
not flood when it rains. Position the filter so that the piping
connections, and winter drain are convenient and accessible for
operation, service, maintenance and winterizing.
2. Position filter so the filter will drain by gravity.
3. If practical, place pump and filter in the shade to shield it from
continuous, direct heat from the sun.
4. Assemble appropriate Filter Control valve (See Page 7 for
selection) to filter. Lubricate the O-ring first (we recommend using
Jack’s 327 Lubricant). Align the two (2) valve pipe connections, with
O-rings in place, with the two openings in the side of the filter tank
and press in firmly. Secure the assembly to the tank connections with
the two bulkhead lock nuts. Do not over-tighten.
5. Connect the pool suction plumbing between the skimmer, pool
outlet and the pump.
6. Install the pool return plumbing.
7. If pressure gauge is not installed, apply Teflon tape to the gauge
threads and carefully screw the gauge into the gauge adapter
assembly.
8. Do not locate pump controls over or near filter.
