IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS

This pump is not a substitute for properly installed and secured pool drain covers. An

ANSI/ASME A112.19.8 approved anti-entrapment drain cover must be used for each drain. Pools and spas should utilize two drains per pump. If a drain cover becomes loose, broken or is missing, close the pool or spa immediately and shut off the pump until an approved anti-entrapment drain cover is properly installed with the manufacturer’s supplied screws.

The SVRS (Safety Vacuum Release System) feature of this pump is inactive during priming.

The SVRS feature is an integral part of a complete safety system. During priming mode, the pump does not monitor blocked suction or discharge system conditions. Swimmers should not be allowed in the pool during the “inactive” SVRS mode. When “SVRS” text is not displayed on the control panel screen, the SVRS system is disabled.

Entrapment Avoidance Notice:

The covers used on suction outlets should be approved and listed as conforming to the currently publishededitionofANSI/ASMEA112.19.8Standard. 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 OFTHE POOLOR SPAWHEN COVERSARE MISSING, CRACKED OR BROKEN CAN RESULT IN BODY OR LIMB ENTRAPMENT, HAIR ENTANGLEMENT, EVISCERATION AND DEATH.

RISK OF ELECTRICAL SHOCK. Connect only to a branch circuit protected by a ground-fault circuit interrupter (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.

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION

This pool pump must be installed by a licensed or certified electrician or a qualified pool service person in accordance with the current 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.

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 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.

•Suction check valves and hydrostatic valves shall not be used with this pump;

•When check valves are installed on the discharge side of the pump a SVRS Check Valve Kit (P/N 350250Z) must be installed.

Never open the inside or 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 capable of 174 GPM or 104 feet of head; use caution when installing and programming

to limit pumps performance potential with old or questionable equipment.

SVRS (Safety Vacuum Release System) feature is DISABLED during priming. When “SVRS” text is

not displayed on the control panel screen, the SVRS feature is disabled.

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.

Always disconnect power to the pool pump at the circuit breaker and remove the RS-485 communication cable from the pump 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.

SVRS devices shall only be installed in conjunction with ASME A112.19.8 suction fitting,

or a 12 in. x 12 in. (305 mm x 305 mm) drain grate or larger, or an approved channel drain system at each suction outlet or drain outlet.

INTELLIFLO® VS+SVRS and INTELLIPRO® VS+SVRS Variable Speed Pump Installation and User’s Guide

iv

IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS

All SVRS devices shall be factory set or field adjusted to site-specific hydraulic conditions. Once

installed, the system shall be tested by simulating an entrapment event.

A ball, butterfly, or sliding gate valve shall be installed within 2 ft. (0.6m) upstream from the

SVRS (between the SVRS and the protected suction outlet), or a test mat shall be used to cover the suction outlet to simulate an entrapment event. There shall be three simulated entrapment tests conducted to verify proper adjustment and operation of the device.

The pump has been designed to specifically operate with Pentair control systems. Operating the

pump with other manufacturers’ controllers may cause software failure of the pump, drive or other system components. Such failure can result in severe personal injury (i.e., failure of the SVRS system, electrical shock) or death. If installed properly, an IntelliComm® Communication Center may be used to integrate other manufacturer’s controllers.

HAZARDOUS PRESSURE: Stand Clear of Pump and Filter During Startup

Install all electrical controls at equipment pad, such

as on/off switches, timers, and control systems,

etc. to allow the operation (startup, shutdown, 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 systems startup, shutdown or servicing of the system filter.

The presence of a hydrostatic valve in the suction piping has been shown to prolong the

high vacuum present at the drain, even through the drain was protected by an SVRS device.

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 use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.

Do not permit children to use this product.

For units intended for use in other than single-family dwellings, a clearly labeled emergency switch

shall be provided as part of the installation. The switch shall be readily accessible to the occupants and shall be installed at least 5 feet (1.52m) away, adjacent to, and within sight of, the unit.

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

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

When setting up pool water turnovers or flow rates the operator must consider local codes governing

turnover as well as disinfectant feed ratios.

Install the pump 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.

A No. 8 AWG or larger conductor must be wired to the motor bonding lug.

This pump is for use with permanently installed pools and may also be used with hot tubs and

spas if so marked. Do not use with storable pools. A permanently 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 may be readily disassembled for storage and reassembled to its original integrity and has a maximum dimension of 18 feet (5.49m) and a maximum wall height of 42 inches (1.07m).

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

spa unless so marked.

Pump is capable of generating systems pressures up to 50 psi. Installers must ensure that all system

components are rated to withstand at least 50 psi. Over pressurizing the system can result in catastrophic component failure or property damage.

Two Speed Pump Controls Notice (Title 20 Compliance)

Please read the following important Safety Instructions (See page 16 for pump speed setup). When using two-speed pumps manufactured on or after January 1, 2008, the pump’s default circulation speed MUST be set to the LOWEST SPEED, with a high speed override capability being for a temporary period not to exceed one normal cycle, or two hours, whichever is less.

INSTALLATION

Only a qualified plumbing professional should install the IntelliFlo® VS+SVRS Variable Speed Pump. Refer to “Important Pump Warning And Safety Instructions” on pages ii - iv for additional installation and safety information.

The pump and its packaged components may have shifted during transport. When unpacking the pump at the installation site, carefully remove the pump to avoid damaging it. Inspect the pump for any damage before beginning the following installation procedures.

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 efficiency, use short, direct suction piping returns.

2.Install a minimum of 5 feet (1.5 meters) from the inside wall of the pool and spa. Canadian installations require a minimum of 9.8 feet (3 meters) from pool water level.

3.Install the pump a minimum of 3 feet (0.9 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 excessive moisture (i.e., rain gutter downspouts, sprinklers, etc.)

6.Install the pump with a rear clearance of at least 3 inches (76.2 mm) so that the motor can be removed easily for maintenance and repair. See Figure 1.

Optional Keypad Relocation Kit

In special cases when the user lacks easy or convenient access to the IntelliFlo VS+SVRS Variable Speed Pump, a Keypad Relocation Kit (P/N 356904Z [Almond] or 356905Z [Black]) may be purchased from your local pool equipment supplier. This kit allows the user to remove the keypad from the top of the drive and mount the keypad in a fixed location with better access.

For installation instructions refer to the Keypad Relocation Kit Installation Instructions provided with the kit.

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.

Piping

1.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.

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.We also recommend a valve, elbow or tee installed in the suction line should be no closer to the front of he pump than five

(5) times the suction line pipe diameter. See Figure 2.

Example: A 2 inch pipe requires a 10 inch (254 mm) 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 and outlet.

5.When first starting the pump, confirm that the suction pressure does not exceed 25 Inches of Mercury (inHg) or 12.2 PSI. Run the pump at the highest speed with the provided suction pressure gauge installed in the front drain plug port on the pump strainer housing. The suction pressure must be lower than 25 inHg or SVRS event detection will not function properly.

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 five times the suction pipe diameter as described in this section.

Check and Bypass Valves

Avoid the use of check or bypass valves in an SVRS equipped system. An operating check or bypass valve will cause changes in system flow that the pump may interpret as a suction blockage event, resulting in consistent tripping and resets of the pump.

There are some cases where back-flow prevention is necessary, such as in systems where a chlorinator or heater is present. Below are a few ways to control back-flow:

1.A Hartford loop can be installed in the system plumbing. A Hartford loop is a small section of plumbing that is built above the highest point of the system's waterline. This loop causes the water head to equalize and prevents the water from draining back into the filter and pump. See Figure 3 below for an example of this installation.

Figure 3: Example of a Hartford Loop Installation

2.If a check or bypass valve must be installed, the minimum speed will need to be set higher than the speed at which the valve opens. This will prevent the pump from passing through the speed range that activates the valve. See page 10, Set Minimum Speed (RPM) for instructions on setting the pump's minimum speed.

Electrical Installation

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. This 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, users or others due to electric shock.

Read all servicing instructions before working on the pump.

Note: ALWAYS reinstall the drive lid onto the field wiring compartment when leaving the pump unsupervised during servicing. This will prevent foreign matter (i.e. rainwater, dust, etc.) from accumulating in the drive.

Note: When connecting the pump to an automation system (IntelliTouch®, EasyTouch®, SunTouch® Control Systems and IntelliComm® Communication Center), continuous power must be supplied to the pump by connecting it directly to the circuit breaker. When using an automation system, be sure that no other lights or appliances are on the same circuit.

Wiring

Grounding

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

STORED CHARGE - Wait at least sixty (60) seconds before servicing.

2.Be sure that the supply voltage meets the requirements listed on the motor nameplate. If these requirements are not met, permanent motor damage may occur.

3.For wiring sizes and general guidelines for proper electrical installation, please follow the specifications defined in the National Electric Code and any local codes as required.

4.Use strain relief and be 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.Reinstall the keypad after wiring the pump by plugging the cover back into the drive wiring connection and reseating the keypad in the desired orientation with the four

(4) corner screws.

Note:Ensure that the keypad cable is not pinched between the drive and keypad during re-seating.

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

2.The pump should be permanently connected to either a circuit breaker, 2-pole timer or 2-pole relay.

Note: If AC power is supplied by a GFCI circuit breaker, the pump should be wired on its own independent circuit unless the pump is operated in tandem with a Pentair salt chlorine generator.

Bonding

1.Bond the motor to the structure in accordance with the National Electrical Code. Use a solid copper bonding conductor not smaller than 8 AWG. For Canadian installations, a 6 AWG or larger solid copper bonding conductor is required. Run a wire from the external bonding screw or lug to the bonding structure.

2.Connect the wire from the accessible bonding lug on the motor to all metal parts of the swimming pool, spa, or hot tub structure and to all electrical equipment, metal conduit, and metal piping within 5 feet (1.52 meters) of the inside walls of the swimming pool, spa, or hot tub. Run a wire from the external bonding screw or lug to the bonding structure.

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

1.Open filter air relief valve.

2.Open valves.

3.Pool return is completely open and clear of any blockages.

4.Water in the pump basket.

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

Priming the Pump

Prime the pump before starting the pump for the first time. Remove the lid and fill the basket with water. The pump basket must be filled with water before initial start up or after servicing.

Follow the steps below to prime the pump for start up:

1.Press Start/Stop to stop the pump. Disconnect the pump main power supply and communication cable.

2.Close all valves in suction and discharge pipes. Relieve all pressure from the system.

3.Remove the pump lid and locking ring.

4.Fill the pump strainer pot with water.

5.Reassemble the pump lid and locking ring onto the strainer basket. The pump is now ready to prime.

6.Open all valves in suction and discharge pipes.

7.Open the filter air relief valve and stand clear of the filter.

8.Connect power to the pump. Be sure green power light is on.

9.Press Start/Stop to start the pump. The pump will enter into priming mode (if enabled) and speed up to the maximum speed set in the pump menu settings.

10.When water comes out of the filter air relief valve, close the valve. The system should now be free of air and recirculating water to and from the pool

11.Do not allow your pump to run longer than 30 minutes time without developing full flow. If the pump does not prime, check your priming settings on the control panel or see the “Troubleshooting” section on pages 27-29.

Priming Features

The default priming setting is ENABLED. The pump also allows you to set the following from the operator control panel:

•Priming speed

•Priming range (1-10)

•Priming delay

Set up instructions on page 17.

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.

This 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.

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 in your pool (half way up skimmer opening). If the water level falls below the skimmer opening, the pump will draw air through the skimmer, 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.
