• Before servicing the pump; switch OFF power to the pump by disconnecting the main circuit to the pump.

• This appliance is not intended for use by persons (including children) of reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.

FAILURE TO FOLLOW ALL INSTRUCTIONS AND WARNINGS CAN RESULT IN SERIOUS BODILY

INJURY OR DEATH. THIS PUMP SHOULD BE INSTALLED AND

SERVICED ONLY BY A QUALIFIED POOL SERVICE PROFESSIONAL. INSTALLERS, POOL OPERATORS AND OWNERS MUST READ THESE WARNINGS AND ALL INSTRUCTIONS IN THE OWNER’S MANUAL BEFORE USING THIS PUMP. THESE WARNINGS AND THE OWNER’S MANUAL MUST BE LEFT WITH THE POOL OWNER.

SUCTION ENTRAPMENT HAZARD: STAY OFF THE MAIN DRAIN AND AWAY FROM ALL SUCTION OUTLETS!

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 (For all permanently

installed units intended for use on 15 or 20 ampere, 125 through 240 volt, single phase branch circuits). 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.

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.

WHISPERFLOXF® VS and MAX-E-PROXF® VS Commercial Variable Speed Pump Installation and User’s Guide

iii

IMPORTANT PUMP WARNING AND SAFETY INSTRUCTIONS

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 anti-entrapment 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 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

(D) Disabled submerged outlets, or

(E) Suction outlets shall be reconﬁgured into return inlets.

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.

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/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.

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.

INSTALLATION

Only a qualiﬁed plumbing professional should install the WhisperFloXF® VS and Max-E-ProXF® VS Commercial Variable Speed Pumps. Refer to “Important 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 efﬁciency, use short, direct suction and return piping.

2. Install a minimum of 5 feet (1.52 meters) from the inside wall of the pool and spa. Canadian installations require a minimum of 9.8 feet (3 meters) from the inside wall of the pool.

3. Install the pump a minimum of 3 feet (.9 meters) from the heater outlet.

4. Do not install the pump more than 10 feet (3.1 meters) above the water level.

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

6. Install the pump with a rear clearance of at least 3 inches (7.6 cm) so that the motor can be removed easily for maintenance and repair. See Figure 1.

Piping

1. For improved 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 ﬁve (5) times the suction line diameter. See Figure 2.

Example: A 2.5 inch pipe requires a 12.5 inch (31.8 cm) straight run in front of the suction inlet of the pump. This will help the pump prime faster and last longer.

Note: DO NOT install 90° elbows directly into the pump inlet or outlet.

Figure 2: Recommended Piping

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.

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 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.

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 cover onto the ﬁeld wiring compartment when leaving the pump unsupervised during servicing. This will prevent foreign matter (i.e. rainwater, dust, etc.) from accumulating inside the compartment.

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 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 a 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. Wire the pump according to instructions given on the inside of the ﬁeld wiring cover, then secure the ﬁeld wiring cover with the four (4) corner screws.

7. DO NOT install motor starters on these pumps. These devices can cause low input voltage alarms.

Bonding Lug

Factory-Installed

Surge Jumper

Ground Wire

Connection

(Green Screw)

Grounding

1. Permanently ground the motor using the green ground screw (see Figure 3). 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.

3. A surge jumper has been factory-installed between the two (2) bottom screw terminals in the wiring compartment. Ensure this surge jumper is in place before wiring the pump. See Figure 3.

This surge jumper grounds all drive

components and will protect them from repeated voltage surges. If surge jumper is not installed damage to the pump drive may occur.

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 lug to the bonding structure. See Figure 3.

Figure 3

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.

For schedule duration settings, PROGRAMs are prioritized as follows: PROGRAM 1 -> PROGRAM 2

-> PROGRAM 3. PROGRAM 1 is the highest priority,

while PROGRAM 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 PROGRAMs in order to add them to the

PROGRAM currently being adjusted.

Example:

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

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

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

Priming the Pump

This pump is shipped with Priming mode ENABLED. Unless the Priming Speed has been modiﬁed, the pump will ramp up to 3450 RPM when powered on for the ﬁrst time, and the Start/Stop button is pressed.

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

1. Open ﬁlter air relief valve.

2. Open valves.

3. 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.

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.

Prime the pump before starting the pump for the ﬁrst time. To avoid permanent damage to the pump, 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 and disconnect power to the pump at the main circuit breaker.

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

3. Remove the pump lid and locking ring. See Figure 7.

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. Reestablish power to the pump and ensure green power light is on.

9. Press Start/Stop to start the pump. The pump will enter into priming mode (if enabled) and ramp up to the programmed priming speed.

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. The pump will prime for 5 minutes

Note: Do not allow the pump to run longer than 30

minutes time without developing full ﬂow. If the pump does not prime, check your priming speed (see page 8, Priming Adjustment) or refer to the Troubleshooting section on pages 19-21.

Priming Adjustment

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.

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,

Priming will automatically run when the WhisperFloXF® VS or Max-E-ProXF® VS Commercial Variable Speed Pump is started from a stopped state, except when running a Quick Clean cycle. Priming will run at 3450 RPM by default, and will last for 5 minutes. The drive’s screen will display and cycle through the following things “ 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, “ for 10 seconds while running the scheduled speed (See Figure 8). 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 ﬁrst engaged.

”

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 3450 RPM to successfully prime itself.

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

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

Operating the Pump While Running

If power is connected to the pump motor, pressing

any of the following buttons referred to in this section could result in the motor starting. Failure to recognize this could result in personal injury or damage to equipment.

Pressing the Display button will cycle through the current parameters.

• Speed / %FL — current run speed or percent ﬂow

• Time — current time of day

• Duration — amount of time remaining at the current PROGRAM

• Watts — amount of watts currently being consumed

Pressing any of the PROGRAM 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.

When running a Quick Clean cycle, pressing the “+” or “-” arrows will change the speed accordingly. Pressing the Quick Clean button again within 10 seconds after will allow for adjustment of the Quick Clean duration 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.

An active Quick Clean cycle can be stopped by holding the Quick Clean button for 3 seconds. The pump will then return to the appropriate point in its programmed schedule.

Control with External Control and Digital Inputs

The WhisperFloXF® VS or Max-E-ProXF® VS Commercial Variable Speed Pump is compatible with external controls and digital inputs, allowing all four Programs to be controlled remotely. The pump has a sealed digital input port that can be used with Pentair External Control Wiring Kit (Pentair P/N 353129Z) to run the PROGRAMs using digital input signals. When there is an external low voltage signal present on any Digital Input line, the pump will run the settings programmed

When a Digital Input is triggered, the LED above the PROGRAM button will begin to blink and the display will toggle between the display parameter and “EC”. This indicates an External Control is running.

The pump will run the Digital Input as long as the Digital Input trigger is present and will override any schedules programmed 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 Digital Input wires, the pump will resume all schedules programmed via the keypad.

for that Digital Input. The supplied +5V signal is the recommended output used for external control and Digital Inputs.

Connecting to External Controls

Using the Supplied Low Voltage Signal for Digital Control

1. The pump provides a low voltage output signal that can be used to trigger its own Digital Inputs. This signal will need to be switched via the External Control system to engage the PROGRAM it is connected to (see Figure 12). 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 needed to perform a task.

2. The digital input cable included with the External Control Wiring Kit (Pentair P/N 353129Z) will need to be cut to length for the installation. Do not leave excess wire around the installation. The wire should be supported by something rigid if conduit is not used.

At one end of the cable is a molded, watertight connection that plugs into the digital input port on the side of the drive. The opposite end has 6 wires that are deﬁned by Table 3 to the right. When using the +24V signal supplied by the drive, the PROGRAMs should be wired as shown in Figure 12.

3. When there is a low voltage signal present on the PROGRAM Digital Input line the pump will run the settings that are programmed for the PROGRAM that is being triggered. The +24V signal supplied via the red wire is the suggested input for the PROGRAM Digital Inputs. See Figure 12.

Note: Any relay can be associated to any Digital Input. Figure 12 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 +24V Signal (red wire) is output from the drive only, and should never be wired to another power supply!
