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.
An abdominal wound 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.

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 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

WARNINGS AND SAFETY INSTRUCTIONS 2/3

Water temperature in excess of 38° C (100° F) 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 37° C (98.6° F). 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 - WATER TEMPERATURE

OTHER WARNINGS

• The use of alcohol, drugs, or medication can greatly increase the risk of gatal hyperthermia
in hot tubs and spas.

• To reduce the risk of injury, do not permit children to use this product.

• 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 1.52m (5 feet) away, adjacent
to, and within sight of the unit.

• When setting up 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 1.5m (5 feet) from the inside wall of the pool and spa.

• 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 5.49m
(18 feet) and a maximum wall height of 1.07m (42 inches).

• For hot tubs and spa pumps, do not install within an outer enclosure or benaeth the skirt
of a hot tub or spa unless so marked.

• IntelliFlo® VSD2 is capable of generating system 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.

WARNINGS AND SAFETY INSTRUCTIONS 3/3

GENERAL WARNINGS

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

• The IntelliFlo® VSD2 pump is not submersible.

• The IntelliFlo® VSD2 pump is capable of 35 m3/hr or 30 meters of head. Use caution
when installing and programming to limit pumps performance potential with old or
questionable equipment.

• Code requirements for the electrical connection differ from country to country. Install
equipment in accordance with all applicable local codes and ordinances.

• Always press the stopp button and disconnect the communication cable before performing
maintenance.

• Sufficient equipotential bonding (min. 4.5mm² recommended), in accordance with local
regulations, is required on all metal components of the pool including the pool pump. It
is required for electrical safety as well as to reduce the risk of corrosion.

GENERAL INSTALLATION INFORMATION

• 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 components.

• 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.

• In a domestic environment, this product may cause radio interference in which case
supplementary mitigation measures may be required.

• Do not install on IT (insulated terra) mains network (marine applications).

• Fitting a non-return valve after the pump on installation will prevent the impeller from
unwinding and is strongly recommended.

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 RCD/GFCI type A or B.

• 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.
