Disconnect the pump and have the problem corrected by a qualified service representative before using.

CAUTION: 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

• Never open the inside of the drive or motor enclosure. There is a capacitor bank that holds a 230 VAC charge even when there is no power to the unit.
• The pump is 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.

DANGER: 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.

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.

WARNING: 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.

WARNING: 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.

WARNING: 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:

1. 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
2. A properly designed and tested suction-limiting vent system or
3. 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.

CAUTION: 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.

DANGER: 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.

WARNING: 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 mayinclude 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.

INSTALLATION

Only a qualified plumbing professional should install the SuperFlo® High Performance Pump. Refer to “Important Safety Instructions” on pages ii-iii for additional installation and safety information.

Location

Be sure the pump location meets the following requirements:

Note: Do not install this pump within an outer enclosure or beneath the skirt of a hot tub or spa unless marked accordingly.

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 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 and spa.
3. Install the pump a minimum of 3 ft. (0.9 m) from the heater outlet.
4. Do not install the pump more than 10 ft. (3 m) 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 in. (7.6 cm) so that the motor can be removed easily for maintenance and repair.

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. 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 5 times the suction line diameter.
   Example: A 2-inch pipe requires a 10 in (25 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.

Pump Rear Clearance

Recommended Suction 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 Installation

WARNING: 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 (NEC) and all other applicable national or 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.

Wiring

1. Before wiring the pump, ensure all power on the pump’s circuit is turned off at the circuit breaker.
   WARNING: STORED CHARGE – Wait at least 60 seconds before servicing.

2. Become familiar with the wiring diagram and electrical specifications of your particular pump motor. This information is provided on the motor nameplate label found on the side of the motor.

3. Ensure the supply voltage meets the requirements listed on the motor nameplate label. If these requirements are not met, permanent motor damage may occur.

4. For wiring sizes and general guidelines for proper electrical installation, follow the specifications defined in the National Electrical Code and all other applicable national or local codes.

5. 3-Phase motors require external overload protection. An initial inspection is needed to ensure proper rotation of the pump.
   Once installed, momentarily cycle the power on and then off. Note the rotation of the motor fan or shaft as it comes to a stop. If wired correctly the motor shaft and/or fan will match the rotation arrow noted on the pump.

6. Use a strain relief and ensure all electrical connections are clean and tight.

7. Cut all wires to the appropriate length so they do not overlap or touch when connected.

Grounding

1. Permanently ground the motor using the green ground screw. Use the correct wire size and type specified by National Electrical Code. Ensure 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 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 and all other applicable national or local codes. 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 pump’s bonding screw or lug to the bonding structure. 2. Connect the bonding wire to all metal parts of
2. structure and to all electrical equipment, metal conduit and metal piping within 5 ft. (1.5 m) of the inside walls of the pool. Run a wire from the external bonding screw or lug to the bonding structure.

WARNING: Before establishing or restoring power to the pump, be sure all electrical connections are tight and all electrical and wiring compartment covers are properly installed.

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 GFCI breakers which offer appropriate personal protection while meeting 2008 to current NEC Standards for Pool Pumps. See Pentair product catalog for details.

MAINTENANCE

WARNING:   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.

CAUTION: 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

The pump strainer basket is located in front of the the volute. The basket must be kept clean of leaves and debris at all times. View the basket through the ‘See
Through Lid’ to inspect for leaves and debris. Regardless of the length of time between filter cleaning, it is most important to visually inspect the basket at least once a week. A dirty basket will reduce the efficiency of the filter and heater and also put an abnormal stress on the pump motor which would result in a costly repair bill.

To clean the strainer basket:

1. Disconnect all power to the pump at the circuit breaker.

2. Open the filter’s air relief valve and relieve all system pressure.

3. Gently tap the clamp in a counter-clockwise direction to remove the clamp and lid.

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, 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 on the pot. Be sure the lid O-ring is properly placed. Seat the clamp and lid on the pump then turn clockwise until the handles are horizontal.

9. Turn the power “ON” at the house circuit breaker. Reset the pool time clock to the correct time.

10. Open the air relief valve on top of the filter.

11. Stand clear of the filter. Start the pump.

12. Bleed air from the system until a steady stream of water appears. Close the air relief valve.

WARNING: 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

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:

1. Shut off electrical power for the pump at the circuit breaker.
2. Drain the pump by removing the two 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.

In mild climate areas, when temporary freezing conditions may occur, run your filtering equipment all night to prevent freezing.

Strainer Pot Assembly

SERVICING

WARNING: Always disconnect power to the 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.

WARNING:  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.

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 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 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 voids the motor warranty.
5. Clean the lid and clamp, O-ring, and sealing surface of the pump pot.

Protect against moisture

1. Protect from splashing or sprayed water.
2. Protect from extreme weather.
3. If motor internals have become wet – let them 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 voids the motor warranty.

Note: When replacing the motor, be certain that the motor support is correctly positioned to support the size of motor being installed.

Shaft Seal Replacement
The Shaft 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 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:

• 1/4” socket or open-end wrench
• 9/16” open-end wrench
• 1/4” hex-key wrench
• Phillips screwdriver

To disassemble the pump:

1. Disconnect all power to the pump at the circuit breaker.

2. Open the filter’s air relief valve and relieve all system pressure.

3. Drain the pump by removing the two drain plugs.

4. Remove the four bolts securing the motor/ hydraulics sub-assembly to the strainer pot.

5. GENTLY separate the motor/hydraulics subassembly from the strainer pot.

6. Remove the three screws securing the diffuser to the seal plate.
   Note: Diffuser screw may vary depending on the pump manufacturing date.

7. Using a 1/4” hex-key wrench, hold the motor shaft in place at the rear of the motor. This prevents the motor shaft from spinning while removing the impeller and impeller screw.

8. Remove the impeller screw and washer using a Phillips screwdriver. The screw is a left-handed thread and loosens clockwise.

9. Unscrew the impeller from the motor shaft counterclockwise.

10. If replacing the shaft seal, follow the instructions provided with the replacement seal. If not, continue to the next step.

11. Remove the spring half on the shaft seal from the motor shaft.

12. Remove the four bolts securing the seal plate to the motor using a 9/16” wrench.

13. When ready to reassemble, continue to Pump Reassembly on the next page

CAUTION: 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. If the water level falls below the suction port, the pump will draw air through the suction port, 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 damage and personal injury

Pump Reassembly

1. If replacing the shaft seal, follow the instructions provided with the replacement seal. If not, continue to the next step.

2. Remount the seal plate to the motor.

3. Grease the motor shaft threads.

4. Clean both halves of the shaft seal with soapy water and a clean cloth. The white ceramic half is seated in the seal plate.

5. Place the spring half of the shaft seal onto the motor shaft.

6. Using a 1/4” hex-key wrench, hold the motor shaft in place at the rear of the motor. This prevents the motor shaft from spinning while reinstalling the impeller and impeller screw.

7. Reinstall the impeller onto the motor shaft clockwise. Hand tighten only!

8. Ensure the impeller screw washer is in place and thread the impeller screw into the motor shaft counter-clockwise.

9. Reinstall the diffuser, ensuring the line molded onto the diffuser is aligned with the line molded onto the seal plate.

10. Grease the diffuser quad ring and seal plate O-ring prior to reassembly.

11. Grease the bolt threads and assemble the motor/ hydraulics sub-assembly to the strainer pot using.
    Do not fully tighten any of the bolts until all four bolts are in place and finger tightened.

12. When ready to restart the pump, continue to Priming the Pump.

Priming the Pump

If the pump is installed below the water level of the pool, close return and suction lines prior to opening the pump’s strainer pot. Make sure to re-open valves prior to operating.

The pump strainer pot must be filled with water before the pump is initially started.

To prime the pump:

1. Gently tap the clamp in a counter-clockwise direction to remove the clamp and lid.
2. Fill the pump pot and volute up to the inlet port with water.
3. Reinstall the lid by placing the lid on the pot. Be sure the lid O-ring is properly placed. Seat the clamp and lid on the pump then turn clockwise until the handles are horizontal.
4. Open the manual air relief valve on top of the filter.
5. Stand clear of the filter and start the pump.
6. When a steady stream of water flows from the Manual Air Relief Valve, close the valve.
7. The filtration system should now be free of air and recirculating water.
