SUPERFLO® VST, SUPERFLO

VS and SUPERMAX® VS Variable Speed Pumps Installation and User’s Guide
Grounding
1. Permanently ground the motor using the Grounding
Terminal (Figure 3) inside the drive wiring
compartment. Refer to the current National Electrical
Code and any local codes for wire size and type
requirements. Ensure the ground wire is connected to
an electrical service ground.
2. ONLY connect the pump to a supply circuit protected
by a ground-fault circuit-interrupter (GFCI) circuit
breaker.
Note: Pentair oers a 2-Pole 20 Amp GFCI breaker
(P/N PA220GF).
Note: The pump should be wired to its own
independent circuit unless the pump is operated in
tandem with a Pentair salt chlorine generator.
Bonding
1. Using the Bonding Lug located on the side of the
motor (Figure 3), bond the motor to all metal parts of
the pool structure, electrical equipment, metal conduit
and metal piping within 5 ft. (1.5 m) of the inside walls
of the swimming pool, spa or hot tub in accordance
with the current National Electrical Code and any local
codes.
2. Solid copper bonding conductor of 8 AWG or larger is
required. For Canadian installations, 6 AWG or larger
solid copper bonding conductor is required.
The pump accepts 115-230 V, 50 or 60 Hz single
phase input power. Power Connections (Figure 3) are
capable of handling up to 10 AWG solid or stranded
wire.
The motor controller will automatically regulate the
pump speed when running on lower voltage to keep
current below 13.6 A. No wiring change is required
to run the pump on 115 V nominal power, the same
terminals are used as with high voltage wiring.
The drive will operate on 2-Phase Line-Line-Ground
electrical systems as well as Line-Neutral-Ground
systems.
Wiring
1. Ensure all electrical breakers and switches are
turned o before wiring the motor.
STORED CHARGE - Wait at least 5
minutes before servicing.
2. Ensure supply voltage meets the requirements
listed on the motor nameplate.
3. For wiring sizes and general requirements, follow
specications dened by the current National
Electric Code and any local codes. When in doubt
use a heavier gauge (larger diameter) wire.
4. Ensure all electrical connections are clean and
tight.
5. Cut all wiring to the appropriate length so they do
not overlap or touch when connected to terminals.
6. ALWAYS reinstall the drive lid after electrical
installation or before leaving the pump
unsupervised during servicing. This will prevent
rainwater, dust or other foreign matter from
accumulating in the drive.
Note: Ensure wires are not pinched between the
drive body and lid.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. The pump must be installed by a licensed or certied electrician or a qualied
service professional 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 users, installers, or others due to electrical shock, and may
also cause damage to property.
Always disconnect power to the pump at the circuit breaker before servicing the pump. Failure to do so could result in death or
serious injury to service people, pool users or others due to electric shock and/or property damage.
Read all servicing instructions before working on the pump.
