When installing and using this electrical equipment, basic safety precautions should always be followed, include the following:
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.
Do not permit children to use this product.
RISK OF ELECTRICAL SHOCK. Connect only to a branch circuit protected by a ground-fault circuitinterrupter (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.
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.

IMPORTANT SAFETY INSTRUCTIONS

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.

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.

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.

INSTALLATION

Only a qualified plumbing professional should install the WhisperFloXF® VS and Max-E-ProXF® VS Commercial Variable Speed Pumps. Refer to “Important Safety Instructions” on pages i – ii 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 the pump is secured to the equipment pad.

6 IN. (15.2 CM) MINIMUM

ENSURE THE INSTALL 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.

Figure 1

2. Install a minimum of 5 ft. (1.5 m) from the inside wall of the pool and spa. Canadian installations require a minimum of 9.8 ft. (3 m) from the inside wall of the pool.

5 x SUCTION PIPE DIAMETER

3. Install the pump a minimum of 3 ft. (0.9 m) from a heater outlet.

ELBOW

4. Do not install the pump more than 10 ft. (3.1 m) 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.

Figure 2
Fittings and Valves

3 IN. (7.6 CM) MINIMUM

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 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 port. This will help the pump prime faster and last longer.
Note: DO NOT install 90° elbows directly into the suction or discharge ports.

1. Do not install 90° elbows directly into suction port.
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. This will prevent foreign matter (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
DO NOT install this pump in conjunction with a motor starter. Using a motor starter with this pump can cause low voltage alarms and may cause permanent drive damage.
1. Be sure all electrical breakers and switches are turned off before wiring motor. STORED CHARGE – Wait at least 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 corner screws.
Bonding Lug
Factory-Installed Surge Jumper
Ground Wire Connection
(Green Screw)

Grounding
1. Permanently ground the motor using the green ground screw (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 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 ft. (1.5 m) 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.

Using an External Input Signal
When using an externally supplied low voltage signal for external control, input voltage must be within 5-30V AC/DC. The wiring kit’s RED wire is only intended to carry the +24V output signal from the drive and will NOT be used.

The +24V signal (RED wire) is output from the drive only and should never be wired to another power supply. Improper wiring will damage the drive.

The external output signal can be regulated by switches or relays to initiate a desired pump function. If multiple digital inputs are active, the priority is: QUICK CLEAN > PROGRAM 3 > PROGRAM 2 > PROGRAM 1.

TO WIRE FOR EXTERNAL CONTROL USING AN EXTERNAL INPUT SIGNAL:

1. Route the communication cable from the Pump Com Port (Figure 5 on page 5) to the control system wiring compartment.
2. Ensure the cable reaches all necessary terminals and cut to the necessary length.
3. Strip the cable 3/4″ (19 mm).
4. Strip all 24 AWG conductors 1/2″ (13 mm).
5. If using RS-485 Automation Wiring Kit (P/N 356324Z – Black): Wire communication cable to control system as shown in Figure 7A. Note: Unused conductors should be cut off and terminated according to local and national electrical codes.

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 shaft 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 strained pot up to the suction port with water. The strainer pot must be filled with water before initial start-up or after servicing.
TO PRIME THE PUMP:
1. Press Start/Stop to stop the pump and disconnect all power to the pump at the circuit breaker.
2. Close all valves in suction and discharge pipes.
3. Relieve all pressure from the filtration system at the filter air relief valve.
4. Turn the strainer pot lid counter-clockwise and remove it from the pump. See Figure 12.
5. Fill the strainer pot up to the suction port with water.
6. Place the lid onto the strainer pot and tighten clockwise until the lid handles are horizontal. Note: Ensure the lid O-ring is properly placed and is not being pinched between the lid and strainer pot.
7. Open all valves in suction and discharge pipes.
8. Open the filter air relief valve and stand clear of the filter.
9. Reestablish power to the pump and ensure green power light is on.
10. Press Start/Stop to start the pump. The pump will begin to prime (if enabled) and ramp up to the programmed priming speed.
11. When a steady stream of water comes out of the filter air relief valve, close the valve.
12. The pump will prime for 5 minutes. Note: Do not allow the pump to run longer than 30 minutes before succesfully priming. If the pump does not prime, check your priming speed (see Priming Adjustment on page 11) or refer to the TROUBLESHOOTING on page 20.

Priming Adjustment
This pump is shipped with Priming ENABLED. The pump will ramp up to 3450 RPM when the pump is initially started. Before turning the pump ON:
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 shaft 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.

Priming will automatically run when the pump is started, except when running a Quick Clean cycle. Default Priming Speed is 3450 RPM, and will last for 5 minutes. The drive will display and cycle through “PrI — Priming Speed, PrI — Remaining Time”.
If externally controlling the pump via an RS-485
connection and priming is enabled at both the pump and control system: Both priming timers will start simultaneously, but pump priming settings will take priority over the control system settings.
Note: After the pump’s priming cycle has completed, if there is time remaining on the control system priming timer the pump will run the control system priming speed until the timer expires.
During the priming sequence, priming speed can be adjusted between 1700 and 3450 RPM using the “+” and “-” arrows. Setting the priming speed below 1700 RPM, will disable priming and the pump will immediately begin to run the scheduled speed.
When priming is disabled and the pump is started, the screen will display, “PrI — 0FF” for 10 seconds while running the scheduled speed (see Figure 13). This 10 second delay allows time to enable priming by pressing “+”.
If priming is re-enabled, the pump will transition from the scheduled speed to 1700 RPM. If necessary, priming speed can then be increased 1700 RPM by pressing “+”. The 5 minute priming countdown timer starts when priming is first engaged.

Priming time 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.
Test and verify priming speeds more than once, letting the water drain from the system in between each test.
Note: To prevent air from entering the system, the pump strainer pot should always be filled with water up to the bottom of the suction port.

Operating the Pump While Running
If power is connected to the pump, 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 a temporary override. The pump will run the speed and duration programmed for that button. Once completed the pump will return to the appropriate point in the programmed schedule.
Note: If PROGRAM speeds are adjusted while the pump is running, the pump will run the entered speed for the rest of the PROGRAM duration, but will not save the adjustments. Exception: QUICK CLEAN Speed and Duration adjustments will always be immediately saved.

Programming Quick Clean
The pump is equipped with a Quick Clean feature, which can be engaged to temporarily run at higher or lower speeds ranging from 300 to 3450 RPM. At the end of a Quick Clean cycle, the pump will automatically return to the appropriate point in its programmed schedule.
Note: Pressing and holding Quick Clean for more than 3 seconds will cancel a Quick Clean cycle. The pump will then return to the appropriate point in its programmed schedule.
TO PROGRAM QUICK CLEAN: 1. Press Start/Stop to stop the pump. 2. Press Quick Clean. The Quick Clean LED and “Spd
/ %FL” parameter LED will blink while editing. See Figure 15.

Quick Clean
During a Quick Clean cycle, pressing “+” or “-” will change the speed accordingly. Pressing Quick Clean within 10 seconds after will allow for adjustment of the Quick Clean duration using the “+” and “-” arrows. These changes will be saved immediately and are the new settings for Quick Clean. Pressing Quick Clean again will cycle through the two Quick Clean settings. The pump will exit editing mode if no buttons are pressed within 10 seconds.
Note: While in keypad lockout mode the quick clean feature is enabled and the “+” and “-” buttons can be used to make temporary changes. A Quick Clean cycle can be stopped by pressing and holding Quick Clean for 3 seconds. The pump will return to the appropriate point in its 24-hour schedule. When a connected control system is in Service Mode, a pump connected via RS-485 can still run its Quick Clean program. Once Service Mode is enabled the pump display will flash between “SEr” and the current Quick Clean speed (Figure 14). Once Service Mode is disabled the pump will resume normal operation. Note: Quick Clean speed will read 0 when Quick Clean is off.
Figure 14

Figure 15 3. Use “+” and “-” to adjust the Quick Clean speed in RPM. 4. Press Quick Clean. The Quick Clean duration will

MAINTENANCE

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 strainer pot temperature is cool to touch, then open with extreme caution.
Always disconnect power to the pump at the circuit breaker and disconnect the digital input 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.
To prevent damage to the pump and for proper operation of the system, clean pump strainer and skimmer baskets regularly.

Cleaning the Pump Strainer Basket

Winterizing

The strainer pot is located at the front of the pump and houses the pump strainer basket.
The strainer basket can be viewed through the strainer pot lid and should be visually inspected at least once a week. Regularly emptying and cleaning the strainer basket will lead to higher filter and heater efficiency and prevent unnecessary stress on the pump motor.
TO CLEAN THE STRAINER BASKET:

Always disconnect power to the pump at the circuit breaker and disconnect the digital input 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, make 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.
Protect against dirt
1. Protect from any foreign matter. 2. Do not store (or spill) chemicals on or near the
