IMPORTANT SAFETY INSTRUCTIONS

When installing and using this electrical equipment, basic safety precautions should always be

followed, including the following: Failure to follow instructions may result in injury.

READ AND FOLLOW ALL INSTRUCTIONS

IN THIS OWNER’S MANUAL AND ON

EQUIPMENT.

KEEP SAFETY LABELS IN GOOD CONDITION AND

REPLACE IF MISSING OR DAMAGED.

WARNING – To reduce risk of injury, do not permit children to use or climb on this

product. The ANSI/NSPI 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. Closely supervise children at all times.

CAUTION – The Perflex™ Filtration System is intended for use on permanently installed

above-ground swimming pools and may also be used with hot tubs and 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.

Though this product is designed for outdoor use, it is strongly advised to protect the electrical
components from the weather. Select a well-drained area, one that will not flood when it rains. It
requires free circulation of air for cooling. Do not install in a damp or non-ventilated location.

Bond motor to pool structure. Use a solid copper conductor, size or larger. Run wire from
external bonding lug to reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm²) solid copper
bonding wire to the pressure wire connector provided on the motor housing and to all metal parts
of swimming pool, spa, or hot tub, and to all electrical equipment, metal piping or conduit within
5 ft. (1.5 m) of inside walls of swimming pool, spa, or hot tub. (In Canada use No. 6 AWG
bonding wire.)

Perflex™ Extended Cycle Filtration System__________ _________________________

NOTE: The National Electrical Code (NEC) permits use of a cord with a maximum 3 ft.
(1 m) length. If your pump is equipped with a cord complying with the NEC, the following three
(3) items apply.

WARNING – Risk of Electric Shock. Connect only to a grounding

type receptacle protected by a Ground Fault Circuit Interrupter (GFCI). Contact a
qualified electrician if you cannot verify that the receptacle is protected by a
GFCI.

WARNING – To reduce the risk of electric shock replace damaged cord

immediately. Do NOT bury cord. Locate cord to minimize abuse from lawn

mowers, hedge trimmers and other equipment.

WARNING – To reduce the risk of electric shock, do NOT use an extension cord to

connect unit to electric supply. Provide a properly located outlet. Qualified personnel MUST do
all electrical wiring.

CAUTION – All suction and discharge valves MUST be OPEN when

starting the filter system. Failure to do so could result in severe personal injury
and/or property damage. All drains and suction covers MUST have properly
installed covers securely attached with the screws supplied with the covers. If
screws are lost, order replacement parts from your supplier.

DANGER – Suction Entrapment Hazard. Never use the pool or

spa if a drain cover is damaged, cracked, missing, or not securely attached. Suction in drains and
suction outlets can cause drowning, disembowelment, hair or body entrapment, severe injury, and
death. Disembowelment, entrapment, or drowning is possible when body parts or hair come in
contact with damaged, broken, cracked, missing, or unsecured drain covers and suction outlets.
Suction from pumps with only one drain or suction outlet can cause disembowelment,
entrapment, or drowning. Pumps for pools and spas require two (2) functioning suction outlets at
least three (3) feet apart, on two (2) walls or on the floor and one (1) wall of the pool or spa.
Installation of pump and suction outlets must be in compliance with all applicable local building
codes. Replace damaged, broken, cracked, missing, or unsecured drain covers and suction outlets
immediately.

WARNING – Hazardous Pressure. Pumps, filters, and other

equipment/components of a swimming pool filtration system operate under pressure. Incorrectly
installed and/or improperly tested filtration equipment and/or components may fail resulting in
injury and/or property damage. A qualified pool professional MUST conduct all pressure tests.
This product is intended for above-ground/on-ground swimming pool applications only. Do NOT
connect to a high-pressure system such as a municipal water main. To prevent explosion caused
by entrapped air in the filtration system use provided air relief valve to bleed air from the system.
Confirm that ALL filtration system component clamps, bolts, and covers have been tightened to
the manufacturer’s recommendations.

WARNING – Never operate or test the filtration system at more than 30 PSI.

General Information

Introduction

This manual contains information for the proper installation and operation of the Hayward® Perflex™ Filtration
System. All Perflex™ Filtration models are high performance, above-ground swimming pool filters. Instructions in
this manual MUST be followed precisely.

The Hayward Perflex System is a high performance swimming pool filter system having an output rating of 3,000
gallons (11 KL) per hour. Manufactured from durable, corrosion-proof materials, the filter and pump are combined
on a strong, molded mounting base. The system is designed for continuous operation and for installation below the
pool water line. It may be used on fresh or salt-water swimming pools.

The Perflex Filter System uses diatomite filter powder (commonly called D.E.). D.E. is the most efficient dirt
remover known for swimming pool filtration. 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.

The Hayward Perflex D.E. filter provides the deepest, most comprehensive clean, removing microscopic dust and
pollen as small as one micron - 100 times smaller than a grain of salt. It takes care of debris the first time through, so
you can run it fewer hours per day.

Patented Flex-Tubes™ make the Hayward Perflex D.E. filter unique. D.E. filter powder coats the tubes and traps dirt
and impurities as they pass through the filter. When the accumulated dirt builds up pressure and decreases the flow,
conventional filters require backwashing. But with the Hayward Perflex D.E. filter, simply move the unique "Bump"
handle up and down a few times to automatically activate the Flex-Tubes, repositioning the dirt and D.E. within the
filter and extending the filter cycle. 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 Power-Flo Matrix™ Pump Series has been engineered as a uniquely superior above-ground pool pump. With the
single push of a button, this truly versatile pump changes from a vertical to a horizontal discharge and back again. It's
large profile and integrated styling makes the Power-Flo Matrix a swimming pool pump like no other. It is driven by
a heavy duty motor, which is electronically isolated and insulated from the pool water. Output pressure and flow are
tuned to the filter, resulting in a perfectly balanced, non-corrosive system.
