1. Important Safety Instructions
Basic safety precautions should always be followed, including the following: Failure to follow
instructions may result in injury.
This is the safety-alert symbol. When you see this symbol on your pump or in this manual, look
for one of the following signal words, and be alert to the potential for personal injury.
WARNING warns about hazard that could cause serious personal injury, death or major
property damage if ignored presents a potential hazard.
CAUTION warns about hazards that will or can cause minor or moderate personal injury and/or
property damage and if ignored presents a potential hazard. It can also make consumers aware of
actions that are unpredictable and unsafe.
The NOTICE label indicated special instructions that are important but not related to hazards.
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 – This product should be installed and serviced only by qualified professionals.
CAUTION – All electrical wiring MUST be in conformance with all applicable local codes,
regulations, and the National Electrical Code (NEC).
WARNING – 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 – Pool and spa components have a finite life. All components should be inspected
frequently and replaced at least every seven years, or if found to be damaged, broken, cracked,
missing, or not securely attached.
WARNING – Suction Entrapment Hazard. Suction in suction outlets and/ or suction outlet
covers, which are damaged, broken, cracked, missing, or unsecured cause severe injury and/ or
death due to the following entrapment hazards (symbols compliments of APSP):
Hair Entrapment – Hair can become entangled in suction outlet cover.
4
Limb Entrapment – A limb inserted into an opening of suction outlet sump or suction outlet cover
that is damaged, broken, cracked, missing, or not securely attached can result in mechanical bind or
swelling of the limb.
Body Suction Entrapment – A differential 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, swimsuits, hair decorations, fingers,
toes, or knuckles to be caught in an opening of a suction outlet cover resulting in mechanical
entrapment.
WARNING – To Reduce the Risk of Entrapment Hazards:
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’) (.91 meter) apart, as measured from near
point to near point.
Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage”
by a user.
Dual suction fittings shall not be located on seating areas or on the backrest for such seating
areas.
The maximum system flow rate shall not exceed the values shown in the “Pipe Sizing Chart”
found on page 12.
Never use pool or spa if any suction outlet component is damaged, broken, cracked, missing,
or not securely attached.
Replace damaged, broken, cracked, or not securely attached suction outlet components
immediately.
In addition to two or more suction outlets per pump installed in accordance with latest APSP
standards and CPSC guidelines, follow all national, state, and local codes applicable.
Installation of a vacuum release or vent system, which relieves entrapping suction, is
recommended.
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 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 mix) is discharged from the valve. All suction and discharge valves MUST be OPEN when
5
starting the circulation system. Failure to do so could result in severe personal injury and/ or
damage.
WARNING – Separation Hazard. Failure to follow safety and operation instructions could
result in violent separation of pump components. Strainer cover must be properly secured to pump
housing. Before servicing pool and spa circulation system, all system and pump controls must be in
off position and filter manual air relief 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 manway cover is in seated position in filter body. All
suction and discharge valves MUST be OPEN when starting the circulation system. Failure to do so
could result in severe personal injury and/ or property damage.
WARNING – Never operate or test the circulation system at more than 50 PSI maximum.
WARNING – Failure to install according to defined instructions may 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.

2. General
NOTICE – Each country (possibly each state) will have its own standards for public and
private pools. It is the responsibility of the installer to be aware of these codes before designing,
specifying or installing any piece of equipment for a swimming pool.
2.1 Swimming Pool Filters
Filters are, without a doubt, the most important
accessory used in the treatment of swimming
pool water. Their purpose is to eliminate
suspended particles from the circulating water,
thus clarity of the water.
The principle operation consists of passing the
swimming pool water through a bed of sand
which will retain any particles that are
suspended in the water.
It should be kept in mind that the filtration
system consists of a number of elements, such
as metering equipment, pumps, pool shell
fittings and pipe work, which ensure the correct
suction and return flows that will affect the
resultant condition of the treated water.
The quality of filtration depends on various
factors, the size and shape of the sand, the
sand bed depth, characteristics of the sand such as granular size, density, etc. A most important
parameter is the water filtration rate. Other factors affecting the selection of a filter are the materials
used for its construction, the working temperature, and the operating pressure.
2.2 Hayward® Filters
Manufactured from proprietary resins and fiberglass, they are virtually corrosion-proof. The internal
fittings (diffuser and lateral system) are manufactured from PVC and ABS. They are unaffected by
salt water and are manufactured for a working pressure up to 50 PSI and a maximum working
temperature of 122° F.
2.3 Selection of Filters and Installation
2.3.1 Filter Characteristics
Choose the filter or filters that meet the local turnover time requirements. Remember it is
possible to add filters together to obtain the correct amount of filtration area required.
Note: when using multiple filters, they must be plumbed in parallel configuration. It is also
a good idea to oversize the surface area required by 10% or more, this will allow for
better water quality. When possible, use more than one filter in conjunction, this will
allow one filter to be serviced while one is still functioning.
