IMPORTANT SAFETY INSTRUCTIONS

When installing and using this electrical equipment, basic safety precautions should always be followed, include the following:

READ AND FOLLOW ALL INSTRUCTIONS

To reduce the risk of injury, 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 qualifi ed 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 fl owing, indicating the possibility of an electric shock. Do not use this pump. Disconnect the pump and have the problem corrected by a qualifi ed 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.

PUMP WARNING AND SAFETY INSTRUCTIONS

For Pool and Spa Pumps (Non SVRS Pumps)

(Pentair Water Pool and Spa ® , Sta-Rite ® , and Pentair Pool Products ® )

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 EN-

TANGLEMENT, BODY ENTRAPMENT, EVISCERATION AND/OR DEATH.

The suction at a pool or spa 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 fl ow 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 fl ow 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, fi nger, 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 NA-

TIONAL AND LOCAL CODES FOR SWIMMING POOLS, SPAS AND HOT TUBS, INCLUDING NSPI

STANDARDS AND CPSC GUIDELINES.

TO MINIMIZE THE RISK OF INJURY DUE TO SUCTION ENTRAPMENT HAZARD:

• Pools and spas should utilize a minimum of two drains per pump.

• 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, close the pool or spa immediately, shut off the pump, post a notice and keep the pool or spa closed until an appropriate certifi ed cover is properly installed.

• Replace drain covers as necessary. Drain covers deteriorate over time due to exposure to sunlight, pool chemicals and weather.

• Avoid getting hair, limbs or body in close proximity to any suction cover, pool drain or outlet.

• Disable suction outlets or reconfi gure into return inlets.

A clearly labeled emergency shut-off switch for the pool pump and spa jet pump must be in an easily accessible, obvious place near the pool or spa. Make sure bathers know where it is and how to use it in case of emergency.

PUMP WARNING AND SAFETY INSTRUCTIONS

For Pool and Spa Pumps (Non SVRS Pumps)

(Pentair Water Pool and Spa ® , Sta-Rite ® , and Pentair Pool Products ® )

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 Specifi cation 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 reconfi gured into return inlets.

v

HAZARDOUS PRESSURE: STAND CLEAR OF PUMP AND FILTER DURING START-UP

Pool and spa circulation systems operate under high pressure. When any part of the circulating system (i.e. locking ring, pump, fi lter, valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the pump housing cover fi lter 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 pool and spa equipment, make note of the fi lter 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 fi lter 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 fl ow freely from the pool and spa back to the pool or spa. Stand clear of all pool and spa equipment and start the pump.

IMPORTANT: Do not close fi lter manual air relief valve until all pressure has been discharged from the

valve and a steady stream of water appears. Observe fi lter pressure gauge and be sure it is not higher than the pre-service condition.

General Installation Information

• All work must be performed by a qualifi ed pool 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 specifi c model. All models are intended for use in swimming pool applications. The pump will function correctly only if it is properly sized to the specifi c 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, fi re, fl ooding, 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.

Electrical controls such as on/off switches, timers, and control systems, etc. should be properly installed to allow the operation (start-up, shut-down, or servicing) of any pump or fi lter without requiring the user to place any portion of his/her body over or near the pump strainer lid or fi lter lid. Such installation should allow the user to stand clear of the fi lter and pump during system start-up, shut down or servicing of the system.

Two Speed Pump Controls Notice California (Title 20 Compliance)

Please read the following important Safety Instructions. When using two-speed pumps manufactured on or after January 1, 2008, the pump’s default circulation speed MUST be set to the LOWEST

SPEED, with a high speed override capability being for a temporary period not to exceed one normal cycle, or two hours, whichever is less.

Installation

Only a qualifi ed service person should install the WhisperFloXF ™ and Max-E-ProXF ™ pumps.

Refer to “Pump Warning And Safety Instructions” on pages ii to vi for additional installation and safety information.

Location

Be sure the pump location meets the following requirements:

•

Pump inlet as close as possible to water level.

•

Short, direct suction piping returns (reduces friction loss).

•

Install pump in a sheltered, well ventilated area to protect from excess moisture (i.e., rain, sprinklers, etc.) and fl ooding.

• Install and secure pump on level concrete slab or fi rm surface (reduce vibration noise).

• Pump location should allow access for servicing and maintenance.

Rear Clearance 3 in minimum

Pump Location Installation Guide:

*Minimum of 9.8 feet (3 m) for Canadian installations.

3 in min.

Piping

Use larger pipe sizes for improved pool plumbing. Pipe diameter should be the same or larger as the return line diameter.

•

Install piping as close to the water level as possible.

•

Run straight, horizontal piping for the suction side of the pump. The length of the piping should be equal to fi ve (5) pipe diameters.

For example, if pool is plumbed with 3 in. diameter PVC pipe, than a straight section of pipe 15 in. long should be used for the suction side of the pump.

5 x Pipe Diameter

Fittings

• Install fi ttings (valves, elbows, tees, etc.) in the suction line no closer than fi ve (5) times the pipe diameter to the front of the pump (eg. 3” pipe = 15 in).

• Do not install 90° elbows directly into pump inlet.

Valves

•

Install gate valves on suction and discharge pipes for maintenance of fl ooded suction systems- install no closer than fi ve (5) times the suction pipe diameter.

• Use a check valve in the discharge line when using this pump for waterfalls, solar heating systems, or in any application where there is signifi cant height to the plumbing after the pump.

• Be sure to install check valves when plumbing in parallel with another pump. This helps prevent reverse rotation of the impeller and motor.

WhisperFloXF ™ and Max-E-ProXF ™ Installation and User’s Guide

Electrical

• 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 fi xed wiring in accordance with the wiring rules.

• If the supply cord is damaged, it must be replaced to avoid a hazard. The supply cord can be purchased separately from the manufacturer, its service agent or a qualifi ed electrician.

Electrical Wiring Installation

To connect the pump to an AC power source:

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

2. Be sure that the supply line voltage matches the motor voltage listed on the motor plate

(example 230 VAC or 115 VAC). If they do not match, permanent motor damage may occur.

3. Use #12 AWG for wire runs up to 100 feet (30.5 meters) and #10 AWG for lengths longer than 100 feet (30.5 meters). When in doubt use a heavier gauge (larger diameter) wire.

Heavier gauge will allow the motor to run cooler and more effi ciently.

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. Permanently ground the motor using the green ground wire, as shown in 3 below. Use the correct wire size and type specifi ed by National Electrical Code. Make sure the ground wire is connected to an electrical service ground.

7. Bond the motor to the pool structure in accordance with the National Electrical Code. UL requires use of a solid copper bonding conductor not smaller than 8 AWG. Run a wire from the external bonding screw or lug to the pool bonding structure.

8. Connect the wire from the accessible wire connector 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 of the inside walls of the swimming pool, spa, or hot tub. For

Canada, a 6 AWG or larger solid copper bonding conductor is required.

9. The pump should be permanently connected to either a circuit breaker, 2-pole timer or 2-pole relay. If AC power is supplied by a GFCI circuit breaker, use a dedicated circuit breaker that has no other electrical loads.

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.

WhisperFloXF ™ and Max-E-ProXF ™ Installation and User’s Guide

Maintenance

Pump Strainer Basket

The strainer basket (‘Hair and Lint Pot’ or ‘Strainer Pot’), is located in front of the pump housing.

The strainer basket must be kept clean and free of leaves and debris. Inspect basket through the ‘See Through Lid’ on the top of the housing.

Be sure to visually inspect the strainer basket at least once a week. Dirty strainer baskets reduce fi lter and heater effi ciency and put abnormal stress on the pump motor.

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.

To prevent damage to the pump and fi lter and for proper operation of the system, clean pump strainer and skimmer baskets regularly.

5

Cleaning the Pump Strainer Basket

1. Turn off the pump at the circuit breaker.

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.

basket 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 lid and locking ring on the pot. Be sure the lid O-ring is properly placed.

Cleaning the Pump Strainer Basket (Continued)

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 blow off which can result in serious injury, death, or property damage. To avoid this potential hazard, follow these instructions.

9. Turn the power “ON” at the house circuit breaker. If applicable, reset the pool time clock to the correct time.

10. Open the manual air relief valve on the top of the fi lter.

11. Stand clear of the fi lter. Start the pump.

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

Winterizing

• In mild climate areas, when temporary freezing conditions may occur, run your fi ltering 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 listed below:

1. Shut off electrical power for the pump at the house 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: Do not wrap motor with plastic or other air tight materials during winter storage. The motor may be covered during a storm, winter storage, etc., but never when operating or expecting operation.

Motor Care

1. Protect from heat

• Shade the motor from the sun.

•

Any enclosure must be well ventilated to prevent overheating.

•

Provide ample cross ventilation.

2. Protect against dirt

•

Protect from any foreign matter or splashing water.

•

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

•

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

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

3. Protect against moisture

• Protect from splashing pool water and lawn sprinklers.

• Protect from the weather.

•

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

•

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

WhisperFloXF ™ and Max-E-ProXF ™ Installation and User’s Guide

Servicing

6. Install the rear plastic cover on the back of the motor.

7. Remount the diffuser onto the seal plate. Make sure the plastic pins and holding screw inserts are aligned (see “TOP” indicator).

8. Assemble the motor subassembly to the housing. Do not tighten the nuts and washers until all four (4) motor bolts are in place. Using a torque wrench, install and tighten the four nuts to a torque value of 100 in-lbs (maximum). Do not overtighten the nuts.

9. Fill the pump with water.

10. Reinstall the pump lid and locking ring; see Maintenance on page 5.

11. Reprime the system.

The Mechanical Seal

The mechanical seal consists primarily of two parts, a rotating member and a ceramic seal.

The pump requires little or no service other than reasonable care. However, a mechanical seal may occasionally become damaged and must be replaced.

WhisperFloXF ™ and Max-E-ProXF ™ Installation and User’s Guide

Restart Instructions

If the WhisperFloXF or Max-E-ProXF pump is installed below the water level of the pool, close return and suction lines prior to opening hair and lint pot on pump. Be sure to reopen valves prior to operating.

Priming the Pump

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.

Note: Running the pump dry could cause a loss of pressure, resulting in damage to the pump case, impeller and seal.

The pump strainer pot must be fi lled with water before the pump is initially started. Follow the steps below to prime the pump:

1. Remove the pump lid and locking ring.

2. Fill the pump strainer pot with water.

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

4. Open the air relief valve on the fi lter, and stand clear of the fi lter.

5. Turn on the pump.

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

7. This pump will prime within 20 minutes. Do not allow your pump to run longer than this time without developing full fl ow. If the pump does not prime, see the “Troubleshooting” section on page 10.

8. Two speed pumps should run on high speed for priming.
