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 in-
staller 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 but-
ton being pushed, a ground current is owing, indicating the possibility of
an electric shock. Do not use this pump. Disconnect the pump and have
the problem corrected by a qualied service representative before using.
IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety
precautions should always be followed, include the following:
Do not permit children to use this product.
RISK OF ELECTRICAL SHOCK. Connect
only to a branch circuit protected by a ground-
fault circuit-interrupter (GFCI). Contact a qualied electrician if you
cannot verify that the circuit is protected by a GFCI.
This pump is for use with permanent swimming pools
and may also be used with hot tubs and spas if so
marked. Do not use with storable pools. A permanent-
ly-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 is capable of being readily disassembled for
storage and reassembled to its original integrity.

ENGLISH
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.
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/o 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, lter lid or valve closures. This installation should
allow the user enough space to stand clear of the
lter and pump during system start-up, shut down or
servicing of the system lter.

or servicing of the system filter.
SAVE THESE INSTRUCTIONS
IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS
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 o 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 ow 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 lter pressure gauge and be sure it is
not higher than the pre-service condition.
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.

Controller Overview
The VS2 Variable Speed Pump uses a premium efciency
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. Pool size, the presence of additional water
features, chemicals used to maintain sanitary conditions, and
local environmental factors will impact optimal programming
necessary to maximize energy conservation.
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. Program 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 strategy to minimize
energy consumption. However, conditions may require running
the pump at a higher speed for some duration of time each day
to maintain proper ltration to achieve satisfactory sanitation.
Note: Optimize the pump to suit individual pool conditions.
Specic conditions including pool size, other devices, features
and environmental factors can all impact the optimal settings.

INSTALLATION
ENGLISH
Fittings and Valves
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, however, the suction gate valve
should be no closer than ve times the suction pipe
diameter as described in this section.
3. Use a check valve in the discharge line when
using this pump for any application where there is
signicant height to the plumbing after the pump.
4. Be sure to install check valves 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 your
national electrical code and all applicable local
codes and ordinances.
• A means for disconnection must be incorporated in
the xed wiring in accordance with the wiring rules.
Only a qualied plumbing professional should install the VS2 Variable Speed Pump. Refer to“Pump Warning
And Safety Instructions”on pages ii-iii for additional installation and safety information.

Location
Note: Do not install this pump within an outer enclosure
or beneath the skirt of a hot tub or spa unless marked
accordingly.
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 pool or spa as
possible. To reduce friction loss and improve
eciency, use short, direct suction and return piping.
2. Install a minimum of 1.5 meters from the inside wall
of the pool and spa.
3. Install the pump a minimum of 1 meter from the
heater outlet.
4. Do not install the pump more than 3 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
10 cm so that the motor can be removed easily for
maintenance and repair. See Figure 1.
Piping
1. For improved pool 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 Pentair 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, elbow or tee installed in the suction line
should be no closer to the front of the pump than
ve (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.

ENGLISH
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.
The 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 eld 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 specied in the local electrical code.
1. Be sure all electrical breakers and switches are turned
o before wiring motor. Always wait ve (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 specied by
the current National Electrical Code. Be sure the ground
wire is connected to an electrical service ground.
6. Bond the motor to all metal parts of the pool structure
and to all electrical equipment, metal conduit and metal
pipping within 5 feet (1.5 M) of the inside walls of the
swimming pool, spa or hot tub in accordance with the
current National Electrical Code. UL requires use of a
solid copper bonding conductor not smaller than 8 AWG.

Control with External Control and Digital Inputs
The user can run the VS2 Variable Speed Pump with automation external controls or Pentair®ControlPro™, allowing all
four programmed Speeds to be controlled remotely. The pump has a sealed connector that can be used with Pentair
Data Cable (optional, 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
The VS2 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 specic speed is needed to perform a task.
The wire included with the Pentair Data Cable (optional, 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 dened 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.

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
into the drive by the user.
Note: The Start/Stop button must be pressed, and the
LED lit, for the pump to run.

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.
Operating the Pump While Running
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
If power is connected to the pump motor, pressing any of the
followingbuttonsreferredtointhissectioncouldresultinthemotorstarting.
Failure to recognize this could result in personal injury or damage to
equipment.
Speed Priorities (Non-External Control)
For schedule duration settings, SPEEDs are prioritized as
follows: 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
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.
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.
• 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 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
If 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 are the new defaults for Quick
clean. Pressing the Quick Clean button again will cycle
through the two Quick Clean settings. The pump will exit
out of editing mode if no additional buttons are pressed
within 10 seconds.
If Quick Clean is running and you wish to stop the Quick
Clean prior to the duration being completed you can
press and hold the Quick Clean button for 3 seconds
and the pump will return to the appropriate point in the
programmed schedule.

Priming will automatically run when the VS2 Variable
Speed Pump is started from a stopped state, except
when running in Quick Clean mode. Priming will run
at 2850 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 11). 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
priming countdown timer starts when priming is rst
engaged.
The installer should set the priming speed to be
sucient 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 your pool’s
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 2850
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.

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
