or damaged.

When installing and using this electrical equipment, basic safety
precautions should always be followed, include the following:

RISK OF ELECTRICAL SHOCK. Connect only to

a branch circuit protected by a ground-fault circuit­interrupter (GFCI). Contact a qualified electrician if you cannot verify that
the circuit is protected by a GFCI.

This unit must be connected only to a supply circuit

that is protected by a ground-fault circuit-interrupter
(GFCI). Such a GFCI should be provided by the installer and should
be tested on a routine basis. To test the GFCI, push the test button.
The GFCI should interrupt power. Push the reset button. Power should
be restored. If the GFCI fails to operate in this manner, the GFCI is
defective. If the GFCI interrupts power to the pump without the test button
being pushed, a ground current is flowing, indicating the possibility of an
electric shock. Do not use this pump. Disconnect the pump and have
the problem corrected by a qualified service representative before using.

General Warnings

• Never open the inside of 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 pump is not submersible.

• The pump is capable of high flow rates; 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, state to state, as well as local municipalities. Install
equipment in accordance with the current National Electrical Code
and all applicable local codes and ordinances.

• Before servicing the pump; switch OFF power to the pump by
disconnecting the main circuit to the pump.

• This appliance is not intended for use by persons (including
children) of reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given
supervision or instruction concerning the use of the appliance by a
person responsible for their safety.

FAILURE TO FOLLOW ALL INSTRUCTIONS AND
WARNINGS CAN RESULT IN SERIOUS BODILY

INJURY OR DEATH. THIS PUMP SHOULD BE INSTALLED AND SER-

VICED ONLY BY A QUALIFIED SERVICE PROFESSIONAL. INSTALL­ERS, OPERATORS AND OWNERS MUST READ THESE WARNINGS
AND ALL INSTRUCTIONS IN THE OWNER’S MANUAL BEFORE US­ING THIS PUMP. THESE WARNINGS AND THE OWNER’S MANUAL
MUST BE LEFT WITH THE PRODUCT OWNER.

SUCTION ENTRAPMENT HAZARD: STAY OFF
THE MAIN DRAIN AND AWAY FROM ALL SUCTION
OUTLETS!

IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS

NOTE: ALL SUCTION PLUMBING MUST BE INSTALLED IN
ACCORDANCE WITH THE LATEST NATIONAL AND LOCAL CODES,
STANDARDS AND GUIDELINES.

A clearly labeled emergency shut-off switch for the
pump must be in an easily accessible, obvious place.

Make sure users know where it is and how to use it in case of emergency.

For Installation of Electrical Controls at Equipment Pad (ON/OFF
Switches, Timers and Automation Load Center)

Install all electrical controls at equipment pad, such
as on/off switches, timers, and control systems,
etc. to allow the operation (startup, shut-down, or
servicing) of any pump or filter so the user does not
place any portion of his/her body over or near the
pump strainer lid, filter lid or valve closures. This
installation should allow the user enough space to
stand clear of the filter and pump during system

start-up, shut down or servicing of the system filter.

This pump has been evaluated for use with water only.

Before operation, be sure to completely rinse the
pump volute with water.

HAZARDOUS PRESSURE: STAND CLEAR OF
PUMP AND FILTER DURING START UP

Circulation systems operate under high pressure.
When any part of the circulating system (i.e.
locking ring, pump, filter, valves, etc.) is serviced,
air can enter the system and become pressurized.
Pressurized air can cause the pump housing cover,

filter lid and valves to violently separate which can
result in severe personal injury or death. Filter tank lid and strainer cover
must be properly secured to prevent violent separation. Stand clear of
all circulation system equipment when turning on or starting up pump.

Before servicing equipment, make note of the filter pressure. Be sure
that all controls are set to ensure the system cannot inadvertently start

during service. Turn off all power to the pump. IMPORTANT: Place filter

manual air relief valve in the open position and wait for all pressure
in the system to be relieved.

Before starting the system, fully open the manual air relief valve and place
all system valves in the “open” position to allow water to flow freely from the
tank and back to the tank. Stand clear of all equipment and start the pump.

IMPORTANT: Do not close filter manual air relief valve until all
pressure has been discharged from the valve and a steady stream
of water appears. Observe filter pressure gauge and be sure it is not

higher than the pre-service condition.

Cord Connected Models Only

RISK OF ELECTRICAL SHOCK. This pump is

supplied with a grounding conductor and grounding
type attachment plug. To reduce the risk of electric shock, be certain that
it is connected only to a properly grounded, grounding-type receptacle.

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.

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 aquaculture systems.

SAVE THESE INSTRUCTIONS

General Installation Information

• All work must be performed by a qualified service professional, and
must conform to all national, state, and local codes.

• Install to provide drainage of compartment for electrical components.

• 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 aquaculture applications. The pump will
function correctly only if it is properly sized to the specific application
and properly installed.

Controller Overview

The Taurus VS Variable Speed Pump uses a premium
efficiency variable speed motor that provides tremendous
program flexibility in terms of motor speed and duration
settings. The pump is intended to run at the lowest speeds
needed to maintain a sanitary environment, which in
turn minimizes energy consumption. Reservoir size,
the presence of additional equipment, use of sanitation
chemicals and local environmental factors will impact
optimal programming necessary to maximize energy
conservation.

This pump is for use with 115/208-230 Vrms

nominal, and in aquaculture applications ONLY.

Connection to the wrong voltage, or use in other application may cause

damage to equipment or personal injury.

The integrated electronics interface controls the speed
settings as well as the run durations. The pump can
operate at speeds ranging between 300 and 3450 RPM
and will operate within the voltage range of 99-253
Vrms at either 50 or 60Hz input frequency.
customization may require some trial-and-error to
determine the most satisfactory settings as dictated by
the conditions. In most cases, setting the pump at the
lowest speed for the longest duration is the best str ategy
to minimize energy consumption. However, conditions
may require running the
duration of time each day to maintain proper filtration to
achieve satisfactory sanitation.

Location

Note: Ensure that the pump is mechanically secured to

the equipment pad.

Be sure the pump location meets the following
requirements:

1. Install the pump as close to the body of water
as possible. To reduce friction loss and improve
efficiency , use short, direct suction and return piping.

2. Install a minimum of 5 feet (1.52 meters) from the
perimeter of the body of water. Canadian installations
require a minimum of 9.8 feet (3 meters) from the
inside wall of the body of water.

3. Install the pump a minimum of 3 feet (.9 meters) from
the heater outlet.

4. Do not install the pump more than 10 feet (3.1 meters)
above the water level.

5. Install the pump in a well ventilated location protected
from excess moisture (i.e. rain gutter downspouts,
sprinklers, etc.).

6. Install the pump with a rear clearance of at least 3
inches (7.6 cm) so that the motor can be removed
easily for maintenance and repair. See Figure 1.

Piping

1. For improved plumbing, it is recommended to use
a larger pipe size.

2. Piping on the suction side of the pump should be the
same or larger than the return line diameter.

3. Plumbing on the suction side of the pump should be
as short as possible.

4. For most installations P entair recommends installing
a valve on both the pump suction and return lines
so that the pump can be isolated during routine
maintenance. However, we also recommend that a
valve, elbo w or tee installed in the suction line should
be no closer to the front of the pump than five (5)
times the suction line diameter. See Figure 2.

Example: A 2.5 inch pipe requires a 12.5 inch
(31.8 cm) straight run in front of the suction inlet of
the pump. This will help the pump prime faster and
last longer.

Note: DO NOT install 90° elbows directly into the
pump inlet or outlet.

Fittings and V alves

1. Do not install 90° elbows directly into pump inlet.

2. Flooded suction systems should have gate valves installed
on suction and discharge pipes for maintenance, howe ver,
the suction gate valve should be no closer than fiv e times
the suction pipe diameter as described in this section.

3. Use a check valv e in the discharge line when using this
pump for any application where there is significant height
to the plumbing after the pump.

4. Be sure to install check valv es when plumbing in parallel
with another pump. This helps prevent reverse rotation
of the impeller and motor.

Electrical Requirements

• Install all equipment in accordance with the National

Electrical code and all applicable local codes and
ordinances.

• A means for disconnection must be incorporated in the

fixed wiring in accordance with the wiring rules.

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. The Taurus™ VS Variable Speed Pump must be installed by a
licensed or certified electrician or a qualified 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 or others due to electric shock and/or property damage.

Read all servicing instructions before working on the pump.

Wiring Overview and Installation

Power should be turned off when installing,

servicing, or repairing electrical components.

Observe all warning notices posted on the existing equipment, pump,

and in these installation instructions.

The Taurus VS Variable Speed Pump must be wired
according to the local electrical codes and standards.
Always refer to the National Electrical Code. This
pump should be installed by a licensed electrician.

The pump accepts 99-253V, 50 or 60Hz single phase
input power. The terminal block connections are
capable of handling up to 10AWG solid or stranded
wire. There are also fast-on type quick connectors,
however, check the local electrical codes for the
desired connection method. The connections must
be permanently made to the grounding terminal (see
Figure 3) in the field wiring compartment according
to the local electrical code. The motor controller will
automatically regulate the pump’s speed when running
on lower voltage to keep the current below 13.2A.
There is no wiring change required to run the pump on
110V 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. This pump must be permanently connected
by a circuit breaker as specified in the local electrical
code.

1. Be sure all electrical breakers and switches are turned
off before wiring motor. Always wait five (5) minutes
after disconnecting the power from the pump before
opening or servicing the drive.

2. Choose a wire size for the pump in accordance with
the current National Electrical Code and all applicable
local codes and ordinances. When in doubt use a
heavier gauge (larger diameter) wire. Be sure the
wiring voltage is within the operating range.

3. Be sure all electrical connections are clean and tight.

4. Cut wires to the appropriate length so they do not
overlap or touch when connected to the terminal
board.

5. Permanently ground the motor using the ground
screw located on the inside rear of the controller
interface (see Figure 3). Use the correct wire size
and type specified by the current National Electrical
Code. Be sure the ground wire is connected to an
electrical service ground.

6. Bond the motor to all electrical equipment, metal
conduit and metal piping within 5 feet (1.5 M) of the
inside walls of the body of water in accordance with
the current National Electrical Code. UL requires use
of a solid copper bonding conductor not smaller than
8 AWG. See Figure 3.

Note: For Canada, a 6 AWG or larger solid copper

bonding conductor is required.

7. The pump should be permanently connected to either
a circuit breaker, 2-pole timer or 2-pole relay. If AC
power is supplied by a GFCI circuit breaker, use a
dedicated circuit breaker that has no other electrical
loads.

8. Connect the pump permanently to a circuit. Make
sure no other lights or appliances are on the same
circuit.
