IMPORTANT SAFETY PRECAUTIONS

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.

WARNING — 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.

WARNING — 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 S tandard 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 A1 12.19.8 S tandard covering Suction Fittings
for Use in Swimming Pools, Wading Pools, S pas and Hot T ubs. 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 SP A WHEN COVERS ARE CRACKED OR BROKEN CAN RESUL T
IN HAIR ENT ANGLEMENT WHICH CAN RESUL T IN DEA TH.

WARNING — Risk of electrical shock or electrocution.

This pool pump must be installed by a licensed or certified electrician or a qualified pool
serviceman in accordance with the National Electrical Code and all applicable local codes
and ordinances. Improper installation will create an electrical hazard which could result in
death or serious injury to pool users, installers, or others due to electrical shock, and may
also cause damage to property.

Always disconnect power to the pool pump at the circuit breaker before servicing
the pump. Failure to do so could result in death or serious injury to serviceman, pool users

or others due to electric shock.

IntelliFlo VS-3050 Installation and User’s Guide

IMPORTANT SAFETY PRECAUTIONS (continued)

WARNING — Water temperature in excess of 100° Fahrenheit 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.). The symptoms of hyperthermia include: drowsiness, lethargy, dizziness,
fainting, and an increase in the internal temperature of the body .

The 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.

WARNING — The use of alcohol, drugs, or medication can greatly increase the risk of fatal

hyperthermia in hot tubs and spas.

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

supervised at all times.

WARNING — For units intended for use in 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.

iii

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

governing turnover as well as disinfectant feed ratios.

WARNING — Before servicing the system, switch the main power OFF and remove the communication

cable from the pump.

CAUTION — 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.
CAUTION — A No. 8 A WG or larger conductor must be wired to the motor bonding lug.
CAUTION — 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 inst alled 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).
CAUTION — 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.
CAUTION — IntelliFlo 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.

General Installation Information

• All work must be performed by a licensed electrician, and must conform to all national, state,

and local codes.

• Install to provide drainage of compartment for electrical components.

IMPORTANT SAFETY PRECAUTIONS (continued)

General Installation Information

WARNING — 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.

WARNING — The pump can produce high levels of suction within the suction side of the

plumbing system. These high levels of suction can pose a risk if a person comes
within the close proximity of the suction openings. A person can be seriously
injured by this high level of vacuum or may become trapped and drown. It is
absolutely critical that the suction plumbing be installed in accordance with the
latest national and local codes for swimming pools.

• These instructions contain information for a variety of pump models and therefore some
instructions may not apply to a specific model. All models are intended for use in swimming
pool applications. The pump will function correctly only if it is properly sized to the specific
application and properly installed.

General Warnings

• Never open the inside or the drive motor enclosure. There is a capacitor bank that holds a
230 VAC charge even when there is no power to the unit.

• The IntelliFlo VS-3050 pump is not submersible

• The IntelliFlo VS-3050 pump is capable of 174 GPM or 104 feet of head; use caution when
installing and programming to limit pumps performance potential with old or questionable
