THESE WARNINGS AND THE OWNER’S MANUAL MUST BE LEFT WITH THE POOL OWNER.
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 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.
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 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 is capable of being readily disassembled for storage and reassembled to its original integrity.
General Warnings

• 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 electrical connection differ from country to country, state to state, as well as local municipalities. Install equipment in accordance with the 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.

SUCTION ENTRAPMENT HAZARD: STAY OFF THE MAIN DRAIN AND AWAY FROM ALL SUCTION OUTLETS! THIS PUMP IS NOT EQUIPPED WITH SAFETY VACUUM RELEASE SYSTEM (SVRS) PROTECTION AND DOES NOT PROTECT AGAINST BODY OR LIMB ENTRAPMENTS, DISEMBOWELMENTS (WHEN A PERSON SITS ON A BROKEN OR UNCOVERED POOL DRAIN) OR HAIR ENTANGLEMENTS.![PENTAIR IntelliFlo VSF Variable Speed and Flow Pool Pump

• Symbols 5](https://manuals.plus/wp-content/uploads/2023/10/PENTAIR- IntelliFlo-VSF-Variable-Speed-and-Flow-Pool-Pump-Symbols-5.png)THIS PUMP PRODUCES HIGH LEVELS OF SUCTION AND CREATES A STRONG VACUUM AT THE MAIN DRAIN AT THE BOTTOM OF THE BODY OF WATER. THIS SUCTION IS SO STRONG THAT IT CAN TRAP ADULTS OR CHILDREN UNDER WATER IF THEY COME IN CLOSE PROXIMITY TO A DRAIN OR A LOOSE OR BROKEN DRAIN COVER OR GRATE.
  THE USE OF UNAPPROVED COVERS OR ALLOWING USE OF THE POOL OR SPA WHEN COVERS ARE MISSING, CRACKED OR BROKEN CAN RESULT IN BODY OR LIMB ENTRAPMENT, HAIR ENTANGLEMENT, BODY ENTRAPMENT, EVISCERATION AND/OR DEATH.
  The suction at a drain or outlet can cause:
  Limb Entrapment: When a limb is sucked or inserted into an opening resulting in a mechanical bind or swelling. This hazard is present when a drain cover is missing, broken, loose, cracked or not properly secured.
  Hair Entanglement: When the hair tangles or knots in the drain cover, trapping the swimmer underwater. This hazard is present when the flow rating of the cover is too small for the pump or pumps.
  Body Entrapment: When a portion of the body is held against the drain cover trapping the swimmer underwater. This hazard is present when the drain cover is missing, broken or the cover flow rating is not high enough for the pump or pumps.
  Evisceration/Disembowelment: When a person sits on an open pool (particularly a child wading pool) or spa outlet and suction is applied directly to the intestines, causing severe intestinal damage. This hazard is present when the drain cover is missing, loose, cracked, or not properly secured.
  Mechanical Entrapment: When jewelry, swimsuit, hair decorations, finger, toe or knuckle is caught in an opening of an outlet or drain cover. This hazard is present when the drain cover is missing, broken, loose, cracked, or not properly secured.
  NOTE: ALL SUCTION PLUMBING MUST BE INSTALLED IN ACCORDANCE WITH THE LATEST NATIONAL AND LOCAL CODES, STANDARDS AND GUIDELINES.
  TO MINIMIZE THE RISK OF INJURY DUE TO SUCTION ENTRAPMENT HAZARD:

  • A properly installed and secured ANSI/ASME A112.19.8 approved antientrapment suction cover must be used for each drain.
  • Each suction cover must be installed at least three (3’) feet apart, as measured from the nearest point to nearest point.
  • Regularly inspect all covers for cracks, damage and advanced weathering.
  • If a cover becomes loose, cracked, damaged, broken or is missing, replace with an appropriate certified cover.
  • Replace drain covers as necessary. Drain covers deteriorate over time due to exposure to sunlight and weather.
  • Avoid getting hair, limbs or body in close proximity to any suction cover, pool drain or outlet.
  • Disable suction outlets or reconfigure into return inlets.

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.
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.
The Virginia Graeme Baker (VGB) Pool and Spa Safety Act creates new requirements for owners and operators of commercial swimming pools and spas.
Commercial pools or spas constructed on or after December 19, 2008, shall utilize:
(A) A multiple main drain system without isolation capability with suction outlet covers that meet ASME/ANSI A112.19.8a Suction Fittings for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs and either:
(i) A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 Manufactured Safety Vacuum Release systems (SVRS) for Residential and Commercial Swimming Pool, Spa, Hot Tub, and Wading Pool Suction Systems and/or ASTM F2387 Standard Specification for Manufactured Safety Vacuum Release Systems (SVRS) for Swimming pools, Spas and Hot Tubs or
(ii) A properly designed and tested suction-limiting vent system or
(iii) An automatic pump shut-off system.
Commercial pools and spas constructed prior to December 19, 2008, with a single submerged suction outlet shall use a suction outlet cover that meets ASME/ANSI A112.19.8a and either:
(A) A SVRS meeting ASME/ANSI A112.19.17 and/or ASTM F2387, or
(B) A properly designed and tested suction-limiting vent system, or
(C) An automatic pump shut-off system, or
(D) Disabled submerged outlets, or
(E) Suction outlets shall be reconfigured into return inlets.
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.
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.
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 swimming pool applications. The pump will function correctly only if it is properly sized to the specific application and properly installed.

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.
Pumps and replacement motors that are single speed and one (1) Total HP or greater cannot be sold, offered for sale, or installed in a residential pool for filtration use in California, Title 20 CCR sections 1601-1609.

INSTALLATION

Only a qualified plumbing professional should install the IntelliFlo® VSF Variable Speed and Flow Pump. Refer to “Important Pump Warning And Safety Instructions” on pages i – ii for additional installation and safety information.
Note: The IntelliFlo VSF pump cannot be connected in series with other pumps.
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.

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 the 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.

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.

Optional Keypad Relocation Kit
In special cases when the user lacks easy or convenient access to the IntelliFlo VSF pump, a Keypad Relocation Kit (P/N 356904Z) 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.
Fittings and Valves

1. Do not install 90° elbows directly into pump inlet.
2. Flooded suction systems should have valves installed on suction and discharge pipes for maintenance, however, the suction valve should be no closer than five 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 significant 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 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, 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

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 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 re-seating 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.

Grounding

1. Permanently ground the drive 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.

Note: When the 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 POWER LINE TERMINALS.
Pentair offers 2-Pole 20 Amp GFCI breakers (P/N PA220GF) which offer personnel protection while meeting 2008 to current NEC Standards for Pool Pumps.
Connecting to an Automation System
All IntelliFlo and IntelliPro pumps, including the IntelliFlo® VSF Variable Speed and Flow Pump, are compatible with Pentair Automation Systems.
An RS-485 communication cable is provided with the pump and will be used to connect the pump to a Pentair automation system.
Refer to the automation system manual for further details on how to connect and use the system with your variable speed pump.
An IntelliTouch® Control System with firmware 1.170 or earlier will display “VSF+SVRS” in the pump type/selection. While you will choose this option, the IntelliFlo VSF pump DOES NOT incorporate SVRS entrapment protection.

OPERATING THE PUMP

NOTE: When setting up the IntelliFlo® VSF Variable Speed and Flow Pump, the user must set the pump’s internal clock and establish an operation schedule by following the steps in this manual. Please refer to user’s guide sections: ‘Set Time’ (page 10) and ‘Set Programs 1-8 in Schedule Mode’ (page 15) to schedule a time to run the pump.
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 maximum speed when the pump is powered on for the first time, and the Start/Stop button is pressed. To change the maximum speed of the pump, refer to page 10.
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 25-27.

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 19.
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.

Set Maximum System Pressure
The maximum pressure can be set using the drive, so that the pump does not exceed a set system pressure level when it is asked to do a high power job, or if the system changes during normal operation. This gives the user a better way than Maximum Speed to limit the output of their pump. If the system is less restrictive, then the pump is still capable of the higher flow rates than it would have been if the user had used a speed limit, but the pressure is still limited where the user needed it to be limited.
The pressure is the total system head, so it is a product of the suction pressure and the discharge pressure. The calculated value is equivalent to Total Dynamic Head (TDH). This value may not correspond with the filter’s pressure reading, because it is the TDH across the pump and not the local pressure of the filter.
When the pump is running a Flow Program, it will always attempt to reach the set flow no matter what the system setup is. If the system pressure changes during the run (such as from filter dirt loading, or manually changing a valve position), the drive adjusts motor RPM to maintain a consistent flow rate.
In some cases the newly requested motor speed will increase the discharge pressure in order to maintain the requested flow rate. While maintaining the flow rate, the drive will remain within the pressure and speed limits set within the Min/Max menu. If the pump meets one of the limits, it will continue to run at the limit and the warning light will illuminate. The limit warning will be displayed on the bottom of the drives’ keypad screen indicating that the requested flow rate is not being achieved and which limit that the drive is running into.
When the pump is running a Speed Program, the drive is not monitoring the flow or pressure limits by default.
These features need to be Enabled in the Min/Max menu.

Scheduled Program Priority
When operating the pump in Schedule mode it is important to keep each program within its own individual run time. If program run times overlap the pump will prioritize programs as explained below:
Schedule priorities are in descending order as follows: Highest Flow » Lowest Flow » Highest Speed » Lowest Speed

• When two speed OR two flow program schedules overlap, the pump will run the higher RPM Speed or GPM Flow regardless of program in use.
• When both a speed AND flow program schedule overlap the pump will run the flow program first.
• A manual or egg timer command takes precedent over a running schedule. The manual or egg timer command will operate until completed, unless the next schedule program takes place or another command is given.

External Control
This function is for programming speeds or flows that will run when the IntelliComm® Communication Center sends it a command. For example, Terminal 3 and 4 in the IntelliComm system will correspond to External Control Program

The default setting for Priming is ENABLED. This setting allows the pump to automatically detect if it is primed for startup.
The priming feature increases the pump speed to 1800 RPM and pauses for three (3) seconds. If there is sufficient water flow in the pump basket, the pump will go out of priming mode and run its commanded speed.
If the water flow is not sufficient, the pump speed will increase to the “Priming Speed” setting and remain for the priming delay time (default 20 seconds). If there is sufficient water flow in the pump basket at this time, it will exit priming mode and transition to the commanded speed.
If there is still insufficient flow in the pump basket, as determined by the Priming Range setting, the pump will try to prime at the “Priming Speed” for the amount of time set in the “Maximum Priming Time” menu.
Once the pump achieves prime, it will resume normal operation after the preset priming delay.
Note: It is possible to set “Maximum Speed” too low for the pump to properly prime. Maximum Speed will limit Priming Speed, except in one case. If the Maximum Speed is set below the lowest available Priming Speed (2400 RPM) then the pump will exceed the Maximum Speed while the priming feature is running. This prevents the pump from having trouble priming if the Maximum Speed is set this low. If this is a problem, priming can be disabled in the Priming Menu.

Priming Features
Disabled/Enabled
Default: ENABLED
Allows IntelliFlo® VSF Variable Speed and Flow Pump to automatically detect if pump if is primed for startup. The pump will speed up to 1800 RPM and pause for three (3) seconds – if there is enough water in the basket, the pump will go out of priming mode and run the commanded speed.
Priming Speed
Default: 3450 RPM
The priming speed can be set between 2400 RPM and 3450 RPM. If the pump is on an equipment pad that is close to the water level, it will not need to run at 3450 RPM to successfully prime. The setting can be lowered to prevent running at a higher speed than necessary.
Day to day factors (i.e. local ambient pressure, water/air temperatures, amount of water retained from last system run) can effect priming performance. Because of the frequently changing nature of these factors the priming speed should be set high enough to accommodate environmental and mechanical changes to ensure that the pump can successfully prime. Finding the most effective and efficient speed for your specific needs may take careful testing and evaluation of priming performance.
Max Priming Duration
Default: 11 minutes
The maximum priming time can be set from 1 – 30 minutes. This setting is the amount of time the pump will try to prime before it gives a priming error. If this occurs, fill the pump basket with water and restart the pump.
Priming Range
Default: 5
Priming range can be set from 1-10. The smaller the range, the more water the pump has to be moving to detect that it is primed. At larger ranges, the pump will detect that it is fully primed while moving less water. If the range is set too high, then the pump may exit Priming mode before it has fully primed. The range will automatically adjust with the priming set speed because the flow rates of the pump will be lower at lower speeds.
Priming Delay
Default: 20 seconds
Priming delay can be set from 1 second to 10 minutes.
When a pump ramps to full priming speed in an attempt to establish a prime, priming delay allows the pump to operate at that speed for an additional set period of time prior to continuing on to the requested or scheduled program.
Loss of Prime
Default: Enabled
This feature allows the pump to recognize unanticipated low-flow or no-flow situations while running a program.
For example, the pump will pause for one (1) minute after detecting that it has lost its prime unexpectedly. After this pause the pump will attempt to prime, and if prime is successful it will continue programmed operation. If priming is not successful the pump will continue attempting to prime, per normal priming operation, until a prime is achieved or priming error occurs and is displayed.

This feature allows you to set a speed (4503450 RPM) or flow (20-140 GPM) that runs when the IntelliFlo® VSF Variable Speed and Flow Pump goes into Thermal Mode. The temperature level that you wish Thermal Mode to start can also be set.
IMPORTANT: This feature is for protection of the pump.
Do not depend on the Thermal Mode feature for freeze protection of the pool. Certain situations could cause the pump to sense a different temperature than actual air temperature.
Your automation systems air temperature sensor should be used to sense actual temperature. For example, if the pump is located indoors, the temperature of the room does not indicate the outdoor temperature. The pump does not sense the water temperature.

MAINTENANCE

DO NOT open the strainer pot if IntelliFlo® VSF Variable Speed and Flow 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, be 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.
Pump Strainer Basket
The strainer basket (or ‘strainer pot’), is located in front of the pump housing. The strainer basket must be kept clean and free of debris. Inspect basket through the lid on the top of the housing. Be sure to visually inspect the strainer basket at least once a week. Dirty strainer baskets reduce filter and heater efficiency and put abnormal stress on the pump motor.
Cleaning the Pump Strainer Basket

1. Press Start/Stop button on the pump and turn off the pump at the circuit breaker. Disconnect communication cable from pump.

2. Relieve pressure in the system.

3. Turn the lid and locking ring counter-clockwise and remove from the pump.

4. Remove debris and rinse out the basket. Replace the basket if it is cracked.

5. Put the basket back into the housing. Be sure to align the notch in the bottom of the basket with the rib in the bottom of the volute.

6. Fill the pump pot and volute up to the inlet port with water.

7. Clean the lid and locking ring, O-ring, and sealing surface of the pump pot.
   Note: It is important to keep the lid O-ring clean and well lubricated.

8. Reinstall the lid by placing the locking ring and lid on the pot. Be sure the lid O-ring is properly placed.
   Seat the locking ring and lid on the pump then turn clockwise until the locking ring handles are perpendicular to the inlet.

9. Turn the power “ON” at the circuit breaker.
   Reconnect communication cable from pump.

10. Open the manual air relief valve on the top of the filter. Stand clear of the filter.

11. Wait until all pressure is relieved. Start the pump.

12. Bleed air from the filter until a steady stream of water comes out of the filter air relief valve. Close the manual air relief valve.

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.
Winterizing
To protect the pump electronics from freeze damage, the pump will switch on to generate internal heat as the temperature drops below freezing if Thermal Mode is enabled. The Thermal Mode feature on the pump is not intended to protect the system plumbing from freezing.

• In mild climate areas, when temporary freezing conditions may occur, run your filtering equipment all night to prevent freezing.
• You are responsible for determining when freezing conditions may occur. If freezing conditions are expected, take the following steps to reduce the risk of freeze damage. Freeze damage is not covered under warranty.

To prevent freeze damage, follow the procedures below:

1. Shut off electrical power for the pump at the circuit breaker.
2. Drain the water out of the pump housing by removing the two thumb-twist drain plugs from the housing. Store the plugs in the pump basket.
3. Cover the motor to protect it from severe rain, snow and ice.

Note: The motor may be covered during a storm, winter storage, etc., but never when operating or expecting operation. Never wrap motor with plastic or other air tight materials during winter storage.

SERVICING

Always disconnect power to the IntelliFlo® VSF Variable Speed and Flow Pump at the circuit breaker and disconnect the communication cable 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.
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, be sure the suction and discharge valves are open and strainer pot temperature is cool to touch, then open with extreme caution.
Be sure not to scratch or mar the polished shaft seal faces; seal will leak if faces are damaged. The polished and lapped faces of the seal could be damaged if not handled with care.
Motor and Drive Care
Protect from heat

1. Shade the motor from the sun.
2. Any enclosure must be well ventilated to prevent overheating.
3. Provide ample cross ventilation.
4. Provide a minimum clearance of 3-inches behind the motor fan for proper circulation.

Protect against dirt

1. Protect from any foreign matter.
2. Do not store (or spill) chemicals on or near the motor.
3. Avoid sweeping or stirring up dust near the motor while it is operating.
4. If a motor has been damaged by dirt it may void the motor warranty.

Protect against moisture

1. Protect from continuous splashing or continuous sprayed water.
2. Protect from extreme weather such as flooding.
3. If motor internals have become wet – let it dry before operating. Do not allow the pump to operate if it has been flooded.
4. If a motor has been damaged by water it may void the motor warranty.
5. Be sure to close the keypad cover after every use.

Shaft Seal Replacement
The Shaft Seal consists primarily of two parts, a rotating ceramic seal housed in the impeller and a stationary spring seal in the sealplate. The pump requires little or no service other than reasonable care, however, a shaft seal may occasionally become damaged and must be replaced.
Note: The polished and lapped faces of the seal could be damaged if not handled with care.
Pump Disassembly
Tools required:

• 3/32-inch Allen head wrench
• Two (2) 9/16-inch open end wrenches
• 1/4-inch Allen head wrench
• No. 2 Phillips head screwdriver
• Adjustable wrench

To remove and repair the motor subassembly, follow the steps below:

1. Turn off the pump circuit breaker at the main panel.

2. Disconnect the RS-485 communication cable from the pump (if connected to pump).

3. Drain the pump by removing the drain plugs. No tools are required.

4. Remove the four (4) Phillips head screws from the outer corners of the keypad.

5. Disconnect the keypad from the drive and set it to the side in a safe place.

6. Remove the three (3) Phillips head screws, located inside the drive, that anchor the drive to the motor.

7. Remove the drive by lifting upwards to separate it from the motor.

8. Use the 9/16-inch wrenches to remove the six (6) bolts that hold the housing (strainer pot/volute) to the rear subassembly.

9. Gently pull the two pump halves apart, removing the rear subassembly.

10. Use a 3/32-inch Allen head wrench to loosen the two (2) holding screws located on the diffuser.

11. Hold the impeller securely in place and remove the impeller lock screw by using a Phillips head screwdriver. The screw is a left-handed thread and loosens in a clockwise direction.
    The pump impeller may have sharp edges that could potentially cut or scratch the user’s hands. Pentair recommends that safety gloves be worn when holding the impeller during disassembly and reassembly.

12. Use a 1/4-inch Allen head wrench to hold the motor shaft. The motor shaft has a hex-shaped socket on the end which is accessible through the center of the fan cover.

13. To unscrew the impeller from the shaft, twist the impeller counterclockwise.

14. Remove the four (4) bolts from the seal plate to the motor, using a 9/16-inch wrench.

15. Place the seal plate face down on a flat surface and tap out the carbon spring seat.

16. Clean the seal plate, seal bore, and the motor shaft.

TROUBLESHOOTING

Always disconnect power to the IntelliFlo VSF Variable Speed and Flow Pump at the circuit breaker and disconnect the communication cable 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. DO NOT attempt to adjust or service without consulting your dealer or a qualified pool technician. Read the entire Installation & User’s Guide before attempting to use, service, or adjust the pool filtering system or heater.
Alerts and Warnings
The IntelliFlo® VSF Variable Speed and Flow Pump displays all alarms and warnings on the control panel display.
When an alarm or warning condition exists, the corresponding light will be lit on the display.
In the event of an alarm: The alarm light “ ” will illuminate and all control panel buttons will be disabled until the alarm is cleared. Pressing the Reset button will clear the alarm once the fault condition has been resolved.
In the event of a warning: The warning light ” ” will illuminate, but the pump will continue to run. The speed, flow or pressure limit that is causing the warning must be adjusted in order to correct the warning.
Note: The pump will not start if the impeller is rotating.
Power Out/OFF
The incoming supply voltage is less than required. The drive faults to protect itself from over current. The drive contains capacitors that keep it powered up long enough to save the current run parameters. If power is restored during this process, approximately 20 seconds, the drive will not restart until completed.
Priming Failure
If the pump is not defined as primed within the “Max Priming Duration” it will stop and generate a “Priming Alarm” for 10 minutes, then attempt to prime again. The “Max Priming Duration” is set by the user on the priming menu as discussed on page 19. If the pump cannot prime within five attempts it will generate a permanent alarm that must be manually reset.
Overheat
If the drive temperature gets above 54.4° C (130° F) the pump will slowly reduce speed until the over temperature condition clears.
Thermal Mode
When active, the motor will run at the preset RPM until the drive internal temperature increases above the minimum. The pump’s internal thermal protection is disabled when connected to an automation system.
Thermal protection is provided by selecting YES at the ON WITH FREEZE portion of the circuit function menu in the IntelliTouch® Control System. To re-enable the internal thermal protection, the power to the drive must be cycled off then back on. IMPORTANT: See explanation of Thermal Mode on page 20.
Over Current
Indicated that the drive is overloaded or the motor has an electrical problem. The drive will restart 20 seconds after the over current condition clears.
Over Voltage
Indicates excessive supply voltage or an external water source is causing the pump and motor to rotate thereby generating an excessive voltage on the drives internal DC buss. The drive will restart 20 seconds after the over voltage condition clears.
Internal Error
Indicates that the self-monitoring motor control software has encountered an error. Clear the alarm and restart the pump. If this alarm persists, contact Pentair Technical Service at 1-800-831-7133.
Speed Limit (Warning)
The pump has detected that it has met the maximum allowed speed set in the Min/Max menu. The pump will continue to run, but it will not achieve the desired speed.
Pressure Limit (Warning)
The pump has detected that it has met the maximum system pressure set in the Min/Max menu. The pump will continue to run, but it is not achieving the desired flow rate or speed because of the pressure limit. The feature is enabled by default while running a program at a constant flow rate, but must be enabled manually if the user wants the drive to monitor maximum pressure while running a constant speed program.
Flow Limit (Warning)
The pump has detected that it has met the maximum flow rate set in the Min/Max menu. The pump will continue to run, but it is not achieving the desired speed because it is running at the maximum flow rate. The Maximum Flow can be set in the Max/Min menu. This feature must be enabled in the Min/Max menu to be active while running a speed program.
