IMPORTANT SAFETY PRECAUTIONS

Important Notice:

Attention Installer: This manual contains important information about the installation, operation and safe use
of this product. This information should be given to the owner and/or operator of this equipment.

WARNING — Before installing this product, read and follow all warning notices and instructions which

are included. Failure to follow safety warnings and instructions can result in severe injury ,
death, or property damage. Call [phone] for additional free copies of these
instructions.

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 18" x 23" is used,
anyone blocking the suction outlet with their body can be trapped and held against the
suction outlet. Disembowelment 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 S tandard 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 A1 12.19.8 S tandard covering Suction Fittings
for Use in Swimming Pools, Wading Pools, S pas and Hot T ubs. 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 SP A WHEN COVERS ARE CRACKED OR BROKEN CAN RESUL T
IN HAIR ENT ANGLEMENT WHICH CAN RESUL T IN DEA TH.

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 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 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.

IntelliFlo VS-3050 Installation and User’s Guide

IMPORTANT SAFETY PRECAUTIONS (continued)

WARNING — Water temperature in excess of 100° Fahrenheit 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

98.6° F. (37° C.). 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 — The use of alcohol, drugs, or medication can greatly increase the risk of fatal

hyperthermia in hot tubs and spas.

IntelliFlo VS-3050 Installation and User’s Guide

Priming the pump for the first time, or after service

Before the IntelliFlo VS-3050 pump is started for the first time it must be primed. T o prime a pump means
filling the pump and suction pipe with water. This process evacuates the air from all the suction lines and the
pump. It may take several minutes to prime depending on the depth of water, pipe size and length. It is
easier to prime a pump if you allow all the air to escape from the pump and pipes. The water cannot enter
unless the air can escape. Pumps do not hold prime, the pool piping system has that task.

CAUTION - T o avoid permanent damage to the IntelliFlo pump, before starting the pump, fill the IntelliFlo

housing strainer with water so that the pump will prime correctly . If there is no water in the stainer the pump will
not prime.

• NEVER run the pump dry! Running the pump dry may damage the seals, causing leakage and
flooding!

• Do not add chemicals to the system directly in front of pump suction. Adding undiluted chemicals
may damage the pump and will void the warranty .

• Open gate valves before starting system.

• Pump will prime itself when used in flooded suction system.

• Be sure to release all air from filter and piping system.

• The IntelliFlo pump is a variable speed pump. Typically the lower speeds are used for filtration and
heating. The higher speeds can be used for spa jets, water features, and priming.

7

CAUTION - Before starting this procedure, first read the following
Before removing the pump lid:

Lid

Clamp

1. Press the Stop button if the pump is running before proceeding.

2. Disconnect the communication cable from the pump.

3. Disconnect main power supply

Volute

4. Close the gate valves in suction and discharge pipes.

5. Release all pressure from pump and piping system.

6. Never tighten or loosen the clamp while the pump is operating.

WARNING! If the pump is being pressure tested, release all pressure before removing the trap cover .

Do not block the pump suction while the pump is running. If a body part blocks the pump suction it may cause
severe or fatal injury . Small children using the pool must AL WAYS have close adult supervision.

WARNING! FIRE and BURN HAZARD - The pump motor may run at a high temperatures. To reduce the

risk of fire, do not allow leaves, debris, or foreign matter to collect around the pump motor. T o avoid burns when
handling the motor, shut of f the motor and allow it to cool for 20 minutes before trying to work on it. The IntelliFlo
provides an automatic internal cutoff switch to protect the motor from heat damage during operation.

Priming the pump for the first time, or after service (Continued)

Priming the Pump

• Release all pressure from filter, pump, and piping system; see the filter owner’ s manual.

• In a flooded suction system (water source higher than pump), the IntelliFlo VS-3050 pump will
prime itself when suction and discharge valves are opened.

• If the IntelliFlo pump is not in a flooded suction system, unscrew and remove lid cover; fill the and
pump with water.

• Do not lubricate the trap cover o-ring. The original equipment o-ring contains a permanent internal
lubricant.

NOTICE: If you replace the o-ring with a non-internally lubricated o-ring, you may need to apply a silicone

based lubricant.

• Clean and inspect o-ring; reinstall on trap cover.

• Replace trap cover on trap; turn clockwise to tighten cover.

NOTICE: Tighten the pump lid by hand only (no wrenches)!

Pump should prime now . Priming time will depend on vertical length of suction lift and horizontal length of
suction piping. If pump does not prime, make sure that all valves are open, suction pipe end is under water,
pump suction is below water level, and that there are no leaks in suction pipe.

T o prime the IntelliFlo pump:

1. Turn the pump clamp and lid in a counterclockwise direction until it stops
and remove them.

Clamp

Lid

2. Fill the pump strainer pot with water.

3. Reinstall the pump clamp and lid onto the strainer pot. The pump is now
ready to prime.

4. Make sure all electrical connections are clean and tight.

Volute

5. Open the air release valve on the filter, and stand clear of the filter.

6. Switch the IntelliFlo pump on at the circuit breaker. Ensure that the
green power light is on.

Top view

7. Press the Speed 1 button to select the pump speed of 750 RPM.

8. Press the Start button to start the pump. Use the Up/Down button to increase the speed as necessary
to prime the pump.

9. When water comes out of the air release valve, close the valve. The system should now be circulating water
back to the pool without air bubbles showing in either the hair and lint pot or at the pool return fittings.

10. Use the Up/Down button to adjust the operating speed as desired.

IntelliFlo VS-3050 Installation and User’s Guide

External Control with IntelliComm Communication Center

The IntelliFlo VS-3050 can be remotely controlled by the Pentair IntelliComm Communication Center
using an optional communications cable (P/N 350122). The IntelliComm provides four pairs of input
terminal connections. These inputs are actuated by either 15 - 240 VAC or 15 - 100 VDC. Using the
device's inputs, the programmed IntelliFlo pump speeds can be controlled.

If more than one input is active the highest number will be communicated to the IntelliFlo pump. The
IntelliComm will always communicate to pump address 1.

The following table shows the wiring terminal descriptions for IntelliComm.

Connecting IntelliFlo VS-3050 to an EasyTouch System

The IntelliFlo can be controlled by an EasyT ouch system via the RS-485 communication cable
(P/N 350122). In this configuration, EasyT ouch starts, stops and controls the speed of the IntelliFlo pump.
When the EasyT ouch does this, it rewrites the IntelliFlo memory, which can take several seconds. This
causes a delay after a command is given on the EasyT ouch control panel until the IntelliFlo physically
responds.

The IntelliFlo control panel is disabled when communicating with the EasyT ouch system. Note that
IntelliT ouch will not start communicating with the IntelliFlo until the pump is assigned to a circuit. The
IntelliFlo default pump address is one which is the only address that works with EasyT ouch. See page 6 for
details about how to check the address and change if necessary . For more information, refer to the
EasyT ouch User's Guide (P/N 520584).

T o connect the IntelliFlo communication cable to EasyT ouch load center:

1. CAUTION - Switch the main power off to the EasyT ouch load center.

2. Unlatch the two enclosure door spring latches, and open the door.

3. Remove the two retaining screws securing the high voltage cover panel, and remove it from the
enclosure.

IntelliFlo VS-3050 Installation and User’s Guide

Connecting IntelliFlo VS-3050 to an IntelliTouch System

The IntelliFlo VS-3050 can be controlled by an IntelliT ouch system via the RS-485 communication cable
(P/N 350122). In this configuration, IntelliT ouch starts, stops and controls the speed of the IntelliFlo pump.
When the IntelliT ouch does this, it rewrites the IntelliFlo memory, which can take several seconds. This
causes a delay after a command is given on the IntelliT ouch control panel until the Intelliflo physically
responds.

The IntelliFlo control panel is disabled when communicating with the IntelliT ouch system. Note that
IntelliT ouch will not start communicating with the IntelliFlo until the appropriate pump address is assigned to
a circuit. The IntelliFlo default pump address is one. See page 6 for details about how to check the address
and change if necessary . For more information, refer to the IntelliT ouch User's Guide (P/N 520102).

T o connect the IntelliFlo communication cable to IntelliTouch load center:

User Maintenance

The following information describes how to service and maintain the IntelliFlo VS-3050 pump.

Pump Strainer Basket

The strainer, sometimes referred to as the “Hair and Lint Pot,” is in front of the of the pump. Inside there is
a basket which must be kept clean of leaves and debris at all times. V iew the basket through the top see
through lid to inspect for leaves and debris.

Regardless of the length of time between filter cleaning, it is most important to visually inspect the hair and lint
pot basket at least once a week. A dirty basket will reduce the efficiency of the filter and possibly the heater .

WARNING — DO NOT open the strainer pot if 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 that the strainer pot is cool to the touch, then open with
extreme caution.

17

CAUTION — T o prevent damage to the pump and filter and for proper operation of the system, clean

pump strainer and skimmer baskets regularly .

1. Protect from heat:

• Shade the motor and controller from the sun.

• Any enclosure must be well ventilated to prevent overheating. Particular attention should be paid to the
motor fan cover and the cooling fins between the drive and the motor.

• Provide ample cross ventilation.

2. Protect against dirt:

• Protect from any foreign matter or splashing water.

• Do not store (or spill) pool chemicals near the motor.

• Avoid sweeping or stirring up dust near the motor while it is operating.

• If a motor has been damaged by dirt it voids the motor warranty.

3. Protect against moisture:

• Protect from splashing pool water.

• Protect from the weather.

• Protect from lawn sprinklers.

• If a motor has become wet - let it dry before operating. Do not allow the pump to operate if it has been
flooded.

• If a motor has been damaged by water it voids the motor warranty.

Note: DO NOT wrap motor and controller with plastic or other air tight materials. The motor and
controller may be covered, but not wrapped in plastic, during a storm, for winter storage, etc., but
never when operating, or expecting operation.

When replacing the motor, be certain that the motor support is correctly positioned to support the size of
motor being installed.

IntelliFlo VS-3050 Installation and User’s Guide

Winterizing

T o protect the IntelliFlo pump electronics from damage due to freezing conditions, the pump will switch it
self on to generate internal heat when the air temperature drops below 40° F . This feature is not intended to
protect the system plumbing from freezing.

1. If the air temperature drops below 40° F the water in the pump can freeze and cause damage.
Freeze damage is not warrantable.

2. To prevent freeze damage follow the procedures listed below.

• Shut off electrical power for the pump at the circuit breaker.

• Drain the water out of the pump by removing the two thumb-twist drain plugs located at the bottom of

the volute. Store the plugs in the pump basket.

• Cover the motor to protect it from severe rain, snow and ice.

• Do not wrap the motor in plastic. It will cause condensation and rust on the inside of the motor.

Note: In mild climate areas, when temporary freezing conditions may occur, run your filtering equipment

all night to prevent freezing.

Priming the pump after service

19

Before a system start-up, the pump and system must be manually primed. Make sure to reopen valves
before operating. T o prime IntelliFlo, the strainer pot must be filled with water.

CAUTION — 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. A LWAYS
maintain proper water level in your pool. Continued operation in this manner could cause

a loss of pressure, resulting in damage to the pump case, impeller and seal.

For instructions about how to prime the IntelliFlo pump, refer to “Priming the pump for the first time or after
servicing,” on page 7.

Section 4

Installation and Removal

The following information describes how to install the IntelliFlo VS-3050 pump.

Note: Before installing this product, read and follow all warning notices and instructions on page ii.

IntelliFlo VS-3050 Kit Contents

• IntelliFlo VS-3050 pump

Installing the IntelliFlo

Only a qualified service person should install the IntelliFlo pump.

Location

1. Install the pump as close to the pool or spa as possible. To reduce friction loss and improve efficiency,
use short and direct suction and piping returns.

21

2. Install a minimum of five (5) feet from the inside wall of the pool and spa. Canadian installations require
a minimum of three (3) meters from pool water.

3. Install the pump a minimum of two (2) feet from the heater outlet.

4. Do not install the pump more than (8) feet above the water level.

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

6. For hot tubs and spas, do not install within an outer enclosure or beneath the skirt of a hot tub or spa.

7. Install the pump with a rear clearance of at least 6 inches so that the motor can be removed easily for
maintenance and repair.

Piping

For improved pool plumbing, it is recommended to use a larger pipe size. When installing the inlet and outlet
fittings (male adaptors), use thread sealant. Do NOT use T eflon® tape.

Do not install 90° elbows directly into pump inlet or outlet. A valve, elbow or tee installed in the suction line
should be no closer to the front of the pump than five (5) times the suction line pipe diameter (i.e., two (2)
inch pipe requires a ten (10) inch straight run in front of the suction inlet of the pump). This will help the
pump prime faster and last longer.

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 five (5) times the suction pipe diameter as
described above.

Check Valve

Check valves must be used when the IntelliFlo is used in parallel with other pumps. IntelliFlo pumps cannot
be used in series with other pumps.

Wiring the IntelliFlo VS-3050

T o connect the IntelliFlo to an AC power source:

1. Make sure all electrical breakers and switches are turned off before wiring motor.

2. Make sure that the wiring voltage is 230 VAC ± 10%.

3. Use #12 AWG for wire runs up to 100 feet and #10 AWG for lengths longer than 100 feet. When in
doubt use a heavier gauge (larger diameter) wire. Heavier gauge will allow the motor to run cooler and
more efficient.

4. Make sure all electrical connections are clean and tight.

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

6. Permanently ground the motor using the green ground wire, as shown below. Use the correct wire size
and type specified by National Electrical Code. Make sure the ground wire is connected to an electrical
service ground.

7. Bond the motor to the pool structure in accordance with the National Electrical Code. Use a solid
No. 8 AWG or larger copper conductor. Run a wire from the external bonding lug to the pool bonding
structure, as shown below.

8. Permanently connect the pump to a non-GFCI circuit breaker, two-pole timer or relay in an automation
controller such as IntelliTouch, EasyTouch or IntelliComm, the drive must be powered up to receive and
respond to the RS-485 serial communication from the automation system. Be sure that no other lights or
appliances are on the same circuit.

NOTE: The IntelliFlo pump will not function properly when powered from a GFCI device.
NOTE: When the IntelliFlo pump is started and stopped by removing power with a relay or

timer, a two-pole device should be used to apply and remove power to both of the red power
leads.

The IntelliFlo is designed to be permanently connected to its power source. Typically the pump receives
power directly from the circuit breaker. No contactor or motor starter is required. IntelliFlo can be
operated in “stand-alone” mode, starting and stopping when power is applied or removed. When the drive
powers up it will return to the mode and run status that it was in when power was removed. This setup
maybe appropriate if you need to use existing relays or timers.

9. For wiring pinouts for the communications port, see pages 11, 14 and 15.
