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.

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

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.

When sizing the plumbing for a filtration package be sure to keep in mind that the

velocity of the water in the pipes is very important. Each country or state may have

different maximums for velocity in the plumbing. The recommendations of APSP-7

should be followed.

2.3.2 Installation Characteristics

To insure selection of the correct pump size, the required flow must be obtained by

taking the system head into consideration. The system head is the added difficulty to

move water through the system presented by using, elbows, piping, tees, changes in

elevation, etc.

It is also recommended that the discharge from each pump is brought together in a

single manifold to the filters. This will allow for greater flow rates for the backwash cycle.

Install a check valve ahead of filter inlet to prevent contaminants from draining

back into the pool.

Install a check valve between filter and heater to prevent hot water from backing

up into filter and damaging internal components.

Disposal of “waste water” must meet local, state and national codes.

See Chart on Page 7 for vertical and horizontal clearance.

4. Installation

WARNING –Read and follow all Instructions.

4.1 General Installation Notes

WARNING –This product should be installed and serviced only by a qualified

professional.

Note: Filters are supplied in a box and on a pallet with accessories included. Due to their

weight and size it is recommended that mechanical means be employed to move the filter into

position. It is also very important to inspect the filters carefully before installing. Make note on

the shipping paperwork if there is any damage to the packaging. FRP filters can be damaged

during transportation and it is the responsibility of the installer to inspect at the time of delivery.

Damages to filters from transportation that are not noted on the bill of lading are not covered

by Hayward’s warranty policy and all costs to repair will be the responsibility of the owner.

Never put the sand into the filter until it is in its final working position and all prior steps are

complete.

The filter should be accessible for periodic maintenance or media change. It is absolutely

necessary to leave a minimum access space around the filter(s), as defined on page 7.

The equipment room should be well ventilated an provided with adequate drainage capabilities

so that should an emergency occur, resulting in flooding from a pipe, filter or pump, the water

can be easily removed to avoid property damage. If drainage cannot be supplied directly from

the equipment room, consideration should be given to the installation of alternate system to

remove water from the mechanical room, per federal, state and local codes.

4.2 Filter Installation

Move the filter(s) into place using whatever means available. Do not use the manway cover or

opening to maneuver the filter. Be sure to use care if moving by hand. Before continuing, be

sure that the filter(s) are in the desired location with the connections facing the direction

necessary for proper installation. It is also very important to make sure that the filter is sitting

on a level, hard surface.

It is possible that during transportation, some internal components have loosened. It will be

necessary to remove the filter manway cover and enter the filter, being careful not to break any

of the connections. By hand, check the tightness of all the laterals in the bottom of the filter

making sure they are firmly tightened.

4.2.1 Tank Positioning

Chalk lines are recommended for multiple tank installations and should be laid for positioning

each tank. The shipping pallet for the filter also serves as an anchor bolt hole template(s) to

aid in positioning the filter tank(s).

Attention must be paid to the location and routing of the influent, effluent and waste line

plumbing when planning the proper location of the filter system. The tanks must be level and

parallel to each other or damage may occur to filter tanks, operating valves or connecting

piping.

Anchor bolts, nuts and flat washers can be purchased. Anchor bolts must be installed and

secured to comply with the requirement of specific seismic zones. If the filter room floor is not

level, shims must be used to level the tanks or the face piping plumbing connections may

break or leak.

Select one of the following appropriate assembly steps for your filter system:

4.2.1.1 Positioning Single Tank

Position the tank in the desired location, drill anchor bolt holes, and install anchor bolts,

washers and nuts. Tighten nuts to secure filter system.

4.2.1.2 Positioning Multiple Tanks

Position the tank positioning templates along the chalk line. The templates, when butted

together side by side, will ensure the proper alignment of filter tank to filter tank and tanks to

face piping.

The pallet template footprint is 6” larger than the filter tank. If you are positioning the rear of the

filter tank six (6”) inches away from the mechanical room wall, you must set the templates at

the “C” dimension for proper anchor/ tank location (see figure 4-1).
