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.

INSTALLATION

Only a qualified plumbing professional should install the Taurus™ VS Variable Speed Pump. Refer to “Pump Warning
And Safety Instructions” on pages ii-iii for additional installation and safety information.

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.

GROUND

The user can run the Taurus™ VS Variable Speed Pump with automation external controls, allowing all four
programmed Speeds to be controlled remotely. The pump has a sealed connector that can be used with Pentair
External Control Wiring Kit (Pentair P/N 353129Z) to run the Speeds using digital input signals. When there is an
external low voltage signal present on the Speed Digital Input line, the pump will run the speed programmed for
that Digital Input. The supplied +5V signal is the recommended input used for external control and Speed Digital
Inputs.

Connecting to External Controls

Using the Supplied Low Voltage Signal for Digital Control

This pump provides a low voltage output signal that can be used to trigger its own Digital Inputs. This signal will
need to be switched via the External Control system to engage the speed that it is connected to as in Figure

4. This could be an automation relay or switch in another piece of equipment. This feature could be useful for
ensuring that the pump is running a certain program when a specific speed is needed to perform a task.

The wire included with the External Control Wiring Kit (Pentair P/N 353129Z) will need to be cut to length for the
installation. Do not leave excess wire around the installation, and the wire should be supported by something
rigid if conduit is not used. At one end of the cable is a custom molded, watertight connection that plugs into the
panel connection on the side of the drive. The opposite end has 6 wires that are defined by Table 1 below. When
using the +5V signal supplied by the drive, the speeds should be wired as shown in Figure 4.

When there is a low voltage signal present on the Speed Digital Input line the pump will run the speed that is
programmed for the speed that is being triggered. The +5V signal supplied via the (red) wire is the suggested
input for the Speed Digital Inputs. See Figure 4.

Note: Any relay can be associated to any Digital Input. Figure 4 shows one of many potential wiring options
available to the installer, allowing you to install External Controls in the way that best suits your needs.

Note: This +5V Signal (red wire) is output from the drive only, and should never be wired to another power
supply!

When a Speed Digital Input is triggered, the LED above the Speed button will begin to blink and the display will
toggle between the display parameter and “EC” indicating an External Control is running. The pump will run this
speed as long as the Digital Input trigger is present. This will override the schedule or any user inputs for Speed
selections via the keypad. The Display button is still functional along with the Start/Stop button. Once the Digital
Input trigger is removed from all of the Speed Digital Input wires, the pump will resume the programmed schedule.

Using an Externally Supplied Low Voltage Signal for External Control

When using an externally supplied low voltage signal as the Digital Input trigger, the wire should be connected as
shown in Figure 5. The low voltage input needs to be within the range of 5-30V AC or DC. In this case the red
+5V supply from the motor control will not be used.

Note: This +5V signal (red wire) is output from the drive only and should never be wired to a voltage
supply!

The external low voltage signal can be regulated by switches or relays to activate the desired Digital Input. If more
than one Digital Input is active at one time then they will be resolved by priority.

Setting the Clock

When the pump is first plugged in, the clock will
blink to indicate that is has not been set. Any daily
schedule set by the user will be based on this clock
setting, so it will be necessary to set the clock first.

To Set the Clock:

1. Press and hold the Display button for 3 seconds.

2. Use the “+” and “-” arrows to choose between a
12 or 24 hour time format.

3. Press Display to advance in the Clock Setup
menu

4. Use the “+” and “-” arrows to change the time to
the correct time of day. In the 12 hour time format
AM/PM will display in the bottom right corner.

5. Press Display to advance.

6. Use the “+” and “-” arrows to adjust the screen
backlight brightness.

7. Press Display to exit the Clock Setup menu. The
clock is now set.

During a power outage, the drive will retain the clock
setting in memory for as long as 24 hours. If the
power is out longer than 24 hours the clock will have
to be set again. If the drive has lost the user set time,
the clock will continuously blink until the time is reset.
Once the time is reset the clock will stop blinking.

Note: When power is returned to the pump after
a prolonged outage (24+ hours) the clock will
automatically set itself to the Speed 1 start time, blink
and advance. The pump will also run the associated
schedule from that start time.

Using the Default Schedule

The default schedule is designed to provide enough
daily turnover to service a typical body of water. See
Table 2 for default schedule.

Duration

(Hours)

SPEED 1 2 3000
SPEED 2 10 1400
SPEED 3 2 2200

Table 2: Default Schedule.

SPEED 1 is set to begin at 8:00am and run at 3000
RPM for a duration of 2 hours. When SPEED 1 is
complete the pump immediately begins running the
default SPEED 2. SPEED 2 is factory default to 1400
RPM and will last for 10 hours. When SPEED 2 has
completed its run the pump will run SPEED 3 at 2200
RPM for a duration of two hours.

After 14 hours of run time and completing its run of
SPEED 3, the pump will enter a stationary/paused
state for the next 10 hours. The pump will restart at
8:00am the next morning and cycle through the default
schedule again. The pump will continue to run in this
in this manner until a custom schedule is programmed

12. Use the “+” and “-” arrows to adjust the duration for
SPEED 2 in hours and minutes.

13. Repeat steps 9-12 to program SPEED 3 and
QUICK CLEAN.

Note: Remember that the duration allowed for

SPEED 3 will be limited to the remaining time in
a 24 hour day. Any time in the 24 hour day not
programmed into SPEEDs 1-3, the pump will
remain in a stationary state.

[ SPEED 1 + SPEED 2 + SPEED 3 < 24 Hours ]

14. Press the Start/Stop button and ensure the LED
is lit. The pump is now on and will run the custom
user-programmed schedule.

Note: If the pump has been stopped via the Start/
Stop button, the pump will not run until the pump
is turned back on by the Start/Stop button. If the
Start/Stop LED is illuminated then the pump is on

and will run the programmed schedule.

TAURUS™ VS Variable Speed Pump Installation and User’s Guide

9

Note: If a user wants to have a period of time
during the day when the pump is not running, any
of the SPEEDs can be programmed to 0 RPM. This
will cause the pump to remain stationary/paused
throughout the duration of that SPEED.

Speed Priorities (Non-External Control)

For schedule duration settings, SPEEDs are prioritized
in numerical order: SPEED 1 -> SPEED 2 -> SPEED

3. SPEED 1 is the highest priority, while SPEED 3 is
the lowest.

The drive will not allow a user to program a schedule
of more than 24 hours. When the 24th hour of duration
is programmed it will take time from the lower priority
speeds in order to add them to the SPEED currently
being adjusted.

Example:

Starting Schedule (Before Adjustment)
SPEED 1 duration = 20 hours
SPEED 2 duration = 2 hours
SPEED 3 duration = 2 hours

If the user reprograms SPEED 1 to run for 23 hours,
SPEED 2 (lower priority speed) will automatically
adjust to a 1 hour duration and SPEED 3 (lowest
priority speed) will adjust to a 0 hour duration.

End Schedule (After Adjustment)
SPEED 1 duration = 23 hours
SPEED 2 duration = 1 hour
SPEED 3 duration = 0 hours

Operating the Pump While Running

If power is connected to the pump motor,

pressing any of the following buttons referred to

in this section could result in the motor starting. Failure to recognize

this could result in personal injury or damage to equipment.

Pressing the Display button will cycle through the
current parameters.

• Speed — current run speed

• Time — current time of day

• Duration — amount of time remaining at the

current run speed

• Watts — amount of watts currently being
consumed

Pressing any of the Speed Buttons (“1”, “2”, “3”,
“Quick Clean”) while the pump is running will act as a
temporary override. It will run the speed and duration
that is programmed for that button. Once completed
it will default back to the appropriate point in the
programmed schedule.

Note: If you adjust the speeds of the schedule while
the pump is running, it will run the adjusted speed
for the rest of the current duration, but will not save
the adjustments. Exception: Speed and Duration

adjustments to QUICK CLEAN will always be
immediately saved.

Quick Clean

When running Quick Clean, pressing the “+” or “-” arrows
will change the speed accordingly. Pressing the Quick
Clean button again within 10 seconds of pressing the “+”
or “-” arrows will allow you to adjust the duration of Quick
Clean via the “+” and “-” arrows. These changes will be
saved immediately and will become the new defaults for
Quick Clean. Pressing the Quick Clean button again will
cycle through the two Quick Clean settings. The pump
will exit editing mode if no additional buttons are pressed
within 10 seconds.

When Quick Clean is running and you wish to stop
the Quick Clean prior to the duration being completed,
press and hold the Quick Clean button for 3 seconds
and the pump will return to the appropriate point in the
programmed schedule.

Priming

This pump is shipped with Priming mode ENABLED. Unless the Priming settings are changed in the menu, be aware
that the pump will speed up to the priming speed when the pump is powered on for the first time, and the
start/stop button is pressed.

Before turning the pump ON, be sure the following conditions are met:

1. Open filter air relief valve.

2. Open valves.

3. Return line is completely open and clear of any blockages.

4. Water in the pump basket.

5. Stand clear of the filter or other pressurized vessels.

DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking.

If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water level. If the water level falls below
the suction line, the pump will draw air through the suction line, losing the prime and causing the pump to run dry, resulting in a damaged
seal. Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal and
may cause property and personal injury.

Priming will automatically run when the Taurus™ VS
Variable Speed Pump is started from a stopped state,
except when running in Quick Clean mode. Priming
will run at 3450 RPM by default, and will last for 5
minutes. The drive’s screen will display and cycle
through the following things “PrI - Priming Speed,
PrI -- Remaining Time”.

Once priming has begun, the speed can be adjusted
between 3450 and 1700 RPM using the “+” and “-”
arrows. If it is adjusted below 1700 RPM, Priming
mode will be disabled and the pump will immediately
begin to run the scheduled speed.

When priming is disabled and the pump is started from
a stopped state, the screen will display, “PrI - OFF”
for 10 seconds while running the scheduled speed
(See Figure 10). This allows the user time to enable
priming mode by pressing the “+” arrow. If the user
chooses to re-enable priming mode, the pump will then
transition from the scheduled speed to 1700 RPM.
The user can increase the priming speed from 1700
RPM by pressing the “+” arrow. The 5 minute pr iming
countdown timer starts when priming is first engaged.

The installer should set the priming speed to be
sufficient for priming the pump from a fresh install,
but not so fast that there is a substantial waste of
energy during the 5 minute priming window. The time
the pump needs to achieve prime can change based
on local environmental conditions such as water
temperature, atmospheric pressure, and water level.
All of these things should be taken into consideration
when setting the priming speed, however in most
cases the pump will not need to run at 3450 RPM to
successfully prime itself.

Please test and verify chosen priming speeds more
than once, letting the water drain from the system in
between each test.

Note: The pump strainer basket should always remain
full to the bottom of the inlet in order to prevent air from
entering the system.

Note: The Quick Clean feature does not have a

start time.

2:00

Note: When the Quick Clean duration ends, the pump
resumes the 24 hour schedule at the point where it
normally would be running at that time. The Quick
Clean duration will not affect the start or stop times
of the 24 hour schedule. For example, if Quick Clean
runs during a period overlapping with a later part of
SPEED 1 and an early part of SPEED 2, the start time
of SPEED 3 is not affected.

Note: Pressing/Holding Quick Clean key for more than
three (3) seconds will cancel Quick Clean mode.

Note: During the Quick Clean mode, the pump will not
start with the priming sequence.

Note: It is recommended that you do not set the Quick
Clean duration to 0 HRS. Setting the Quick Clean
duration to 0 HRS will not allow you to change the
duration setting while the motor is running. The motor
will have to be stopped in order to change the Quick
Clean settings if the duration is set to 0 HRS.

Keypad Lockout

Key lockout will not prevent the motor from being

stopped by pressing the Start/Stop button. It will

then be unable to be restarted until the keypad has been unlocked. If

the motor is operating in Keypad Lockout mode, and being controlled

through external controls, it can only run when the Start/Stop LED is

illuminated.

The pump’s user interf ace has a Ke ypad Lock out feature
to prevent unwanted changes to the settings. When
locked, the keypad will only accept input from pressing
the Display button to cycle the displayed information on
the screen and input to stop the motor from a press of
Start/Stop button.

The keypad can be locked by pressing and holding the
“1” button and the Quic k Clean b utton at the same time
for at least three seconds. “Loc On” will be displayed
if successful.

To unlock the keypad press and hold the “1” button and
the Quick Clean button at the same time f or at least three
seconds. “Loc OFF” will be displayed if successful.

Note: While operating in K eypad Lockout mode the motor
can still be stopped by pressing the Start/Stop button.
However, the motor can not be started again until the
user unlocks the keypad.

MAINTENANCE

VOLUTE

THIS SYSTEM OPERATES UNDER HIGH PRESSURE. When any part of the circulating system (e.g., Lock Ring, Pump, Filter,
Valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the lid to separate which can

result in serious injury, death, or property damage. To avoid this potential hazard, follow above instructions.

DO NOT open the strainer pot if Taurus™ VS Variable Speed Pump fails to prime or if pump has been operating without water in

the strainer pot. Pumps operated in these circumstances may experience a build up of vapor pressure and may contain scalding

hot water. Opening the pump may cause serious personal injury. In order to avoid the possibility of personal injury, make sure the

suction and discharge valves are open and strainer pot temperature is cool to touch, then open with extreme caution.

To prevent damage to the pump and for proper operation of the system, clean pump strainer and skimmer baskets regularly.

13

Pump Strainer Basket

The pump strainer basket (or ‘strainer pot’, ‘hair and lint
pot’), is located in front of the volute. Inside the chamber
is the basket which must be kept clean of leaves and
debris at all times. View bask et through the ‘See Through
