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.
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 46 cm x 58 cm 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 ow rate of this pump
should be less than or equal to the maximum approved ow 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.
WARNING — Risk of electrical shock or electrocution.
This pool pump must be installed by a licensed or certied electrician or a qualied pool
serviceman in accordance with 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.
IMPORTANT SAFETY PRECAUTIONS
English

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.
WARNING — When setting up pool water turnovers or ow 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 5 feet (1.5 m) from the inside wall of the pool and spa.
CAUTION — A No. 8 AWG 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 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).
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 30 meters. Installers must ensure
that all system components are rated to withstand at least 30 meters. 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 EU country, and
local codes.
•Install to provide drainage of compartment for electrical components.

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, re, ooding,
suction entrapment or severeinjury 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.
WARNING — In a domestic environment, this product may cause radio interference in
which case supplementary mitigation measures may be required.
WARNING — Do not install on IT (insulated terra) mains network (marine applications)
NOTE — If required by local building codes, the pump is to be supplied by an isolating
transformer or supplied through a residual current device (RCD) having a residual
operating current not exceeding 30 mA.
NOTE — Use only RCD/GFCI suitable for protecting equipment with a DC current content in
the fault current.
• These instructions contain information for a variety of pump models and therefore
some instructions may not apply to a specic model. All models are intended for
use in swimming pool applications. The pump will function correctly only if it is
properly sized to the specic application and properly installed.

Priming the pump for the rst time or after service
BeforetheIntelliFlo®VSpumpisstartedforthersttimeitmustbeprimed.Toprimeapumpmeanslling
thepumpandsuctionpipewithwater.Thisprocessevacuatestheairfromallthesuctionlinesandthepump.
Itmaytakeseveralminutestoprimedependingonthedepthofwater,pipesizeandlength.Itiseasierto
primeapumpifyouallowalltheairtoescapefromthepumpandpipes.Thewatercannotenterunlessthe
aircanescape.Pumpsdonotholdprime,thepoolpipingsystemhasthattask.
CAUTION - To avoid permanent damage to the IntelliFlo® VS pump, before starting the pump, ll the IntelliFlo®
housing strainer with water so that the pump will prime correctly. If there is no water in the stainer the pump will
not prime.
• NEVER run the pump dry! Running the pump dry may damage the seals, causing leakage and
ooding!
• Do not add chemicals to the system directly in front of pump suction. Adding undiluted chemicals
may damage the pump and will void the warranty.
• Open gate valves before starting system.
• Pump will prime itself when used in ooded suction system.
• Be sure to release all air from lter and piping system.
• The IntelliFlo® VS pump is a variable speed pump. Typically the lower speeds are used for
ltration and heating. The higher speeds can be used for spa jets, water features, and priming.
CAUTION - Before starting this procedure, rst read the following
Before removing the pump lid:
1. Press the Stop buttonifthepumpisrunningbeforeproceeding.
1. Disconnect the communication cable from the pump.
2. Close the gate valvesinsuctionanddischargepipes.
3. Release all pressurefrompumpandpipingsystem.
4. Never tighten or loosentheclampwhilethepumpisoperating.
WARNING!If the pump is being pressure tested, release all pressure before removing the clamp.
Do not block the pump suction while the pump is running. If a body part blocks the pump suction it may cause
severe or fatal injury. Small children using the pool must ALWAYS have close adult supervision.
WARNING! FIRE and BURN HAZARD- The pump motor may run at a high temperatures. To reduce the
risk of re, do not allow leaves, debris, or foreign matter to collect around the pump motor. To avoid burns when
handling the motor, shut off the motor and allow it to cool for 20 minutes before trying to work on it. The IntelliFlo
VS provides an automatic internal cutoff switch to protect the motor from heat damage during operation.
