SUCTION ENTRAPMENT HAZARD
F
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.
Hair Entanglement – When the hair tangles or knots in the drain cover, trapping the swimmer underwater.
This hazard is present when the flow rating of the cover 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 cover is missing, broken, loose, cracked or not properly
secured.
Body Entrapment – When a portion of the body is held against the drain cover trapping the swimmer underwater. This hazard is present when the drain cover is missing, broken or the cover flow rating is not high
enough for the pump or pumps.
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 cover 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 cover. This hazard is present when the drain cover is missing, broken, loose,
cracked, or not properly secured.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION:
PUMPS REQUIRE HIGH VOLTAGE WHICH CAN SHOCK, BURN, OR CAUSE DEATH.
BEFORE WORKING ON PUMP!
Always disconnect power to the pool pump at the circuit breaker from the pump before
servicing the pump. Failure to do so could result in death or serious injury to service person,
pool users or others due to electric shock.
IntelliFlo VS-3050 Installation and User’s Guide
IMPORTANT SAFETY PRECAUTIONS (continued)
Water temperature in excess of 100° F (37.7° C) may be hazardous to your health. Prolonged
immersion in hot water may induce hyperthermia. Hyperthermia occurs when the internal
temperature of the body reaches a level several degrees above normal body temperature of
98.6° F (37° C.). 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. The use of alcohol, drugs, or medication can greatly increase the risk
of fatal hyperthermia in hot tubs and spas.
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 may increase the flow rate through the system and
exceed the maximum flow rate stated on the drain cover.
Do not permit children to operate this product.
If this pump is intended for use other than single-family dwellings, a clearly labeled emergency
switch shall be provided as part of the installation. The switch shall be readily accessible to
the occupants and shall be installed at least 5 feet (1.52 m) away, adjacent to, and within
sight of, the unit.
When setting up pool water turnovers or flow rates the operator must consider local codes
governing turnover as well as disinfectant feed ratios.
Before servicing the system, switch the main power OFF and remove the communication
cable from the pump.
Install the pump a minimum of five (5) feet from the inside wall of the pool and spa. Canadian
installations require a minimum of three (3) meters from pool water.
A No. 8 AWG (No. 6 AWG in Canada) or larger conductor must be wired to the motor bonding
lug.
This pump is for use with permanently installed 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 may be readily disassembled for storage and reassembled
to its original integrity and has a maximum dimension of 18 feet (5.49m) and a maximum wall
height of 42 inches (1.07m).
For hot tubs and spa pumps, do not install within an outer enclosure or beneath the skirt of a
hot tub or spa unless so marked.
The IntelliPro pump is capable of generating systems pressures up to 50 psi. Installers must
ensure that all system components are rated to withstand at least 50 psi. Over pressurizing
the system can result in catastrophic component failure or property damage.
iii
Never exceed the maximum stated pump flow rating.
Only use a pumping system rated for the corresponding flow. FAILURE TO DO SO CAN
RESULT IN HAIR OR BODY ENTRAPMENT WHICH CAN CAUSE SERIOUS PERSONAL INJURY OR DEATH. If in doubt about the rating of your system, consult a
qualified pool service professional.
Pumps are not a substitute for properly installed and secured pool drain covers. An ANSI/
ASME A112.19.8 approved anti-entrapment drain cover must be used for each drain. Pools
and spas should utilize a minimum of two drains per pump. Regularly inspect all covers for
cracks, damage and advanced weathering. If a cover becomes loose, cracked, damaged,
broken or is missing, close the pool or spa immediately, shut off the pump, post a notice
and keep the pool or spa closed until an appropriate VGB 2008 certified cover is properly
installed. Covers deteriorate over time due to exposure to sunlight and pool chemicals.
This cover must be replaced within seven (7) years from installation (or earlier if the cover
becomes damaged in any way).

IMPORTANT SAFETY PRECAUTIONS (continued)
Entrapment Avoidance Notice:
The suction outlet connected to a swimming pool or spa pump can pull a high vacuum if it
is blocked. Therefore, if only one suction outlet smaller than 18" x 23" is used, anyone
blocking the suction outlet with their body can be trapped and held against the suction
outlet. Disembowelment or drowning can result. Therefore, if small suction outlets are
used with this pump, to prevent this entrapment and possible death, install at least two
suction outlets in the body of water. Separate these suction outlets as described in the
International Residential Code (IRC), the International Business Code (IBC), the Consumer
Products Safety Council (CPSC) Guidelines for Entrapment Hazards: Making Pools and
Spas Safer or ANSI/IAF-7 Standard for Suction Entrapment Avoidance in Swimming Pools,
Wading Pools, Spas, Hot Tubs and Catch Basins. If suction outlets are not used, additional
entrapment avoidance measures as described in the CPSC Guidelines or ANSI/IAF-7 should
be employed.
The covers used on suction outlets should be approved and listed as conforming to the currently
published edition of ANSI/ASME A112.19.8 Standard covering Suction Fittings for Use in
Swimming Pools, Wading Pools, Spas and Hot Tubs. These covers 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 this pump should be less than or
equal to the maximum approved flow rate indicated on the suction outlet cover by the
manufacturer. THE USE OF UNAPPROVED COVERS OR ALLOWING USE OF THE POOL
OR SPA WHEN COVERS ARE CRACKED OR BROKEN CAN RESULT IN HAIR
ENTANGLEMENT WHICH CAN RESULT IN DEATH.
The Virginia Graeme Baker Pool and Spa Safety Act imposes certain new requirements on owners and
operators of swimming pools and spas.
Pools or spas constructed on or after December 20, 2008, shall utilize:
(A) No submerged suction outlets, a gravity drainage system with ASME/ANSI cover(s), one or more
unblockable outlets; or
(B) A multiple main drain system without isolation capability with suction outlet covers that meet ASME/
ANSI A112.19.8 Suction Fittings for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs and
either:
(i) A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 Manufactured Safety Vacuum
Release Systems (SVRS) for Residential and Commercial Swimming Pool, Spa, Hot Tub, and Wading Pool
Suction Systems and/or ASTM F2387 Standard Specification for Manufactured Safety Vacuum Release
Systems (SVRS) for Swimming Pools, Spas and Hot Tubs or
(ii) A properly designed and tested suction-limiting vent system or
(iii) An automatic pump shut-off system.
Pools and spas construction prior to December 20, 2008, with a single submerged suction outlet shall use a
suction outlet cover that meets ASME/ANSI A112.19.8 and either:
(A) A multiple main drain system without isolation capability, or
(B) A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 and/or ASTM F2387, or
(C) A properly designed and tested suction-limiting vent system, or
(D) An automatic pump shut-off system, or
