F

SUCTION ENTRAPMENT HAZARD

Pool and spa pumps produce high levels of suction, which can pose extreme danger if a person comes in
close proximity to an open pool or spa drain or if a drain grate is loose, cracked, broken or missing.

Pool and spa pumps move large volumes of water, which can pose extreme danger if a person’s hair
comes in close proximity to a drain that is not the proper size for the pump or pumps.

Suction entrapment dangers include:

Hair Entanglement – When the hair tangles or knots in the drain grate, trapping the swimmer underwater. This

hazard is present when the flow rating of the grate is too small for the pump or pumps.

Limb Entrapment – When a limb is sucked or inserted into an opening resulting in a mechanical bind or swelling.
This hazard is present when a drain grate is missing, broken, loose, cracked or not properly secured.

Body Entrapment – When a portion of the body is held against the drain grate trapping the swimmer under­water. This hazard is present when the drain grate is missing, broken or the grate flow rating is not high
enough for the pump or pumps.

StarGuard® Square Drain Installation Guide

WARNINGS AND IMPORTANT SAFETY PRECAUTIONS

Evisceration/Disembowelment – When a person sits on an open pool (particularly a child wading pool) or

spa outlet and suction is applied directly to the intestines, causing severe intestinal damage. This hazard is
present when the drain grate is missing, loose, cracked, or not properly secured.

Mechanical Entrapment – When jewelry, swimsuit, hair decorations, finger, toe or knuckle is caught in an
opening of an outlet or drain grate. This hazard is present when the drain grate is missing, broken, loose,
cracked, or not properly secured.

Use these fittings only with a pumping system rated for the corresponding flow or less for two

(2) inch plumbing (see sump diagram on page 4). FAILURE TO DO SO CAN RESULT IN HAIR
OR BODY ENTRAPMENT WHICH CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. If in doubt about
the rating of your system, consult a qualified pool or spa professional.

IMPORTANT NOTICE

Regularly inspect all drain grates for cracks, damage and advanced weathering. If a drain grate
becomes loose, cracked, damaged, broken or is missing, close the pool or spa immediately, post a
notice and keep the pool or spa closed until an appropriate VGB 2008 certified drain grate is properly
installed. Drain grates deteriorate over time due to exposure to sunlight and pool chemicals. This
drain grate must be replaced within seven (7) years from installation (or earlier if the grate becomes
damaged in any way).

An ANSI/ASME A112.19.8a approved anti-entrapment drain grate must be used

for each drain. Pools and spas should utilize two drains per pump. If a drain grate
becomes loose, broken or is missing, close the pool or spa immediately and shut off the pump until an
approved anti-entrapment drain grate is properly installed with the supplied stainless steel screws. Only
the supplied 316 stainless-steel screws should be used with the drain grate. Substitute screws such as
masonry screws, sheet rock screws or other types of screws should never be used. Screws put into the
frame anywhere except in the original screw holes will not hold and will allow the drain grate to come
off the main drain, causing an entrapment hazard, including possible limb and body entrapment or
evisceration/disembowelment. If the screw holes of the frame are stripped or the brass inserts are
missing, loose, or damaged, replace the frame. DO NOT DRILL NEW SCREW HOLES IN THE FRAME AS
THIS WILL DAMAGE AND WEAKEN THE FRAME.

IMPORTANT NOTICE

Attention Installer: This manual contains important information about the installation, operation and safe use of

this product. This information should be given to the owner and/or operator of this equipment. Please refer to
www.pentair.com for all warnings and instructions related to the StarGuard® Square Drain.

Before installing this product, read and follow all warning notices and instructions which are

included. Failure to follow safety warnings and instructions can result in severe injury, death,
or property damage. Call [phone] for additional free copies of these instructions. It is absolutely critical
that the suction plumbing be installed in accordance with the latest national and local codes for swimming
pools.

A pool/spa pump produces high levels of suction, which can pose extreme danger if a

person comes in close proximity to an open pool or spa drain or a loose or broken drain grate.

Hydrostatic relief valve

For installations utilizing a hydrostatic relief valve, using a collector tube will maintain a clear path to the
hydrostatic valve. At least one hydrostatic relief valve in a set of suction outlets will allow hydrostatic uplift
pressure caused by ground water to be relieved into the pool or spa.

StarGuard® Square Drain Installation Guide

IV

WARNINGS AND IMPORTANT SAFETY PRECAUTIONS

Entrapment Avoidance Notice:

The grates used on suction outlets should be approved and listed as conforming to the currently published
edition of ASME/ANSI A112.19.8a Standard. These grates should be inspected regularly and replaced if
cracked, broken or older than the design lifetime indicated on them by the manufacturer. The maximum
possible flow rate of the pump should be less than or equal to the maximum approved flow rate indicated on the
suction outlet grate by the manufacturer. THE USE OF UNAPPROVED GRATES OR ALLOWING USE OF
THE POOL OR SPA WHEN GRATES ARE MISSING, CRACKED OR BROKEN CAN RESULT IN BODY OR
LIMB ENTRAPMENT, HAIR ENTANGLEMENT, EVISCERATION AND DEATH.

Pumps improperly sized or installed or used in applications other than for which the pump was

intended can result in severe personal injury or death. These risks may include but not be
limited to electric shock, fire, flooding, suction entrapment or severe injury or property damage caused by a
structural failure of the pump or other system component.

The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in

hot tubs and spas.

To reduce the risk of injury, do not permit children to use this product unless they are closely

supervised at all times.

When setting up pool water turnovers or flow rates the operator must consider local codes

governing turnover as well as disinfectant feed ratios.

DO NOT increase pump size; this will increase the flow rate through the system and exceed

the maximum flow rate stated on the drain grate.

StarGuard® Square Drain Installation Guide

WARNINGS AND IMPORTANT SAFETY PRECAUTIONS

Most states and local codes regulate the construction, installation, and operation of

public pools and spas, and the construction of residential pools and spas. It is important to
comply with these codes, many of which directly regulate the installation and use of this product. Consult the
local building and health codes for more information.

• Dual suction fittings shall not be located on seating areas or on the back rests for such seating
areas.

• If the pool or spa has only a single suction outlet or main drain, a Safety Vacuum Release System
(SVRS) such as the Pentair Water Pool and Spa IntelliFlo® VS+SVRS pump, a gravity drainage
system, an automatic shut-off system or a suction-limiting vent system MUST be used.

• In the event one suction outlet is completely blocked, the remaining suction outlets serving the
system shall have a flow rating capable of the full flow of the pump(s) for the specific system.

• An approved anti-entrapment suction outlet grate must be used for each drain.

• Never exceed the maximum flow rate stated on the drain grate.

• Before each use of the facility the suction fitting, including fasteners, should be inspected for
damage or tampering.

• Close the pool or spa if any suction outlet component is loose, cracked, broken, missing or not
securely attached. Replace loose, cracked, damaged, broken or missing drain grates.

• In addition to two or more suction outlets per pump (Figure 2) installed in accordance with the latest
APSP standards and CPSC guidelines, follow all applicable national, state and local codes.

• The suction outlet to a swimming pool pump pulls a high vacuum. If pump is used with only one
suction pipe, anyone blocking pump suction with hair or body will be trapped and held against the
suction fitting. Disembowelment or drowning can result.

• To prevent entrapment, install at least two suction outlet (main drains) fittings per pump in pool.
Separate these outlets by either of the following procedures.

A. Locate the outlets at least three (3) feet apart.

B. Locate the outlets in two (2) different planes (Figure 1), (for example, one on the bottom and one on a

vertical side wall, or on two separate vertical side walls). Use multiple suction sources to reduce risk of
entrapment. Failure to maintain fittings and grates can lead to severe injury or death. Use of fittings
when grates are broken, loose or missing can lead to severe injury or death. If using 1½ in. plumbing.
Consult your local building dept. for codes or ordinances that may apply.

V

• Remove the pressure test plugs and/or plugs used in winterization of the pool/spa from the suction
outlets.

Hydraulic System Specifications

POOL PUMP SUCTION REQUIREMENTS

Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or allow anyone else to
use a pool, spa, or hot tub unless it has at least two (2) suction outlets to each pump suction line (see Figure 1,
Outlets Per Pump, below). Do not use or operate swimming pools, spas, or hot tubs if a suction outlet grate is
missing, broken, or loose. Follow the guidelines below for a pump installation which minimizes risk to users of
pools, spas, and hot tubs.

Entrapment Protection

The pump suction system must provide protection against the hazard of suction entrapment or hair entrapment/
entanglement.

Suction Outlet Grates

All suction outlet grates must be maintained. They must be replaced if cracked, broken, or missing. See page
vii for outlet grate certification requirements. All suction outlets must have correctly installed, screw-fastened
grates in place.

Outlets Per Pump

Provide at least two (2) hydraulically balanced main drains, with grates (see Figure 1), for each swimming pool
pump suction line. The centers of the main drains (suction fittings) must be at least three (3) feet apart.

The system must be built so that it cannot operate with the pump drawing water from only one (1) main drain
(that is, there must be at least two (2) main drains connected to the pump whenever it is running, see Figure 1).
However, if two (2) main drains run into a single suction line, the single suction line may be equipped with a
valve which will shut off both main drains from the pump (see Figure 1).

For existing single drain pools and spas, or multiple main drains located less than three feet (3) apart, a backup
system must be installed, such as the IntelliFlo® VS +SVRS. Other backup systems include, approved gravity
draining systems, or suction-limiting vent.

Water Velocity and Flow Rates

The maximum water velocity through drain grates is limited by some local regulations, for example some state
health departments limit the velocity through public pool drain grates to 1-1/2 feet per second. This velocity
limit is lower than the flow rating provided by the ASME/ANSI A112.19.8a certification, therefore local limit
applies and must be followed. Never exceed the flow rating listed on the grate even if local code does not
provide a velocity limit (see Chart 2 on page 2).

Piping – General

For new installations, the piping between drains must be sized to limit the velocity to six (6) feet per second.
This limit applies to the branch piping and all fittings between multiple outlets and the tee leading back to the
pump. If code requires a lower water velocity, comply with the code. See Chart 1 for information on pipe size
flow ratings at six (6) feet per second.
