(Europe) for additional free copies of these instructions.

Consumer Information and Safety

The EQ Series pumps are designed and manufactured to provide many years of safe and reliable service when installed, operated and maintained according to the information in this manual and the installation codes referred to in later sections. Throughout the manual, safety warnings and cautions are identified by the “ “ symbol.

Be sure to read and comply with all of the warnings and cautions.

DANGER — Risk of electrical shock or electrocution.

This pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman 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 pool users, installers, or others due to electrical shock, and may also cause damage to property.

Always disconnect power to the pool pump at the circuit breaker before servicing the pump. Ensure that the disconnected circuit is locked out or properly tagged so that it cannot be switched on while you are working on the pump. Failure to do so could result in serious injury or death to serviceman, pool users or others due to electric shock.

WARNING — Do not operate the pump until you have read and understand clearly all the operating

instructions and warning messages for all equipment that is a part of the pool circulating system. The following instructions are intended as a guide for initially operating the pump in a general pool installation, however each installation may have unique conditions where the starting procedure could be different. Failure to follow all operating instructions and warning messages can result in property damage or severe personal injury or death.

EQ Series Pump Installation and User’s Guide

IMPORTANT SAFETY PRECAUTIONS (continued)

WARNING — Never exceed the maximum operating pressure or temperature limits of the system

components. Pumps installed with the EQ Strainer Pot Assembly should not be tested at a pressure that exceeds the value written on the EQ Strainer Pot. See the Owner's Manual that accompanies that product for more instructions. Ensure that pressures higher than those required in the pressure test cannot inadvertently be applied to the circulation system. This may require the use of a pressure regulator between the water supply and the circulation system.

Changes in temperature or barometric pressure can cause the internal test pressure to increase or decrease over time once the system is isolated. A pressure relief device should be installed that would prevent the pressure from exceeding the intended test pressure. Exceeding these limits could result in a component failing under pressure. This instantaneous release of energy can cause failed components to be accelerated to high velocities and to travel distances of 100 feet or more. These components could cause severe personal injury or death if they were to strike a person.

WARNING — Due to the potential risk that can be involved it is recommended that the pressure test be

kept to the minimum time required by the local code. Do not allow people to work around the system when the circulation system is under pressure test. Post appropriate warning signs and establish a barrier around the pressurized equipment. If the equipment is located in an equipment room, lock the door and post a warning sign.

iii

Never attempt to adjust any closures or lids or attempt to remove or tighten bolts when the system is pressurized. These actions can result in a separation or failure of system components. This instantaneous release of energy can cause components to be accelerated to high velocities and to travel distances of 100 feet or more. These components could cause severe personal injury or death if they were to strike a person.

CAUTION — This pump is for use with permanently installed 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 may be readily disassembled for storage and reassembled to its original integrity.

IMPORTANT SAFETY PRECAUTIONS (continued)

General Installation Information

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 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.

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.

• 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.

• The pump is available with or without a specially designed strainer pot assembly. If a suction strainer pot assembly is to be provided, it should comply with NSF-50 standards. Pumps without the strainer pot assembly are not self-priming and must be installed so that the pump is always flooded with water. If the pump is to be installed without a strainer pot, plumbing suction inlets must prevent debris larger tha

0.6 cm ( ¼”) in diameter from being drawn into the pump.

• Pumps installed with the specially designed strainer pot assembly are self-priming at heights up to 3 meters (10 feet) depending on the specific installation.

Introduction

EQ Series® High Performance Commercial Pump Overview

The EQ Series pumps deliver extraordinary performance in every key aspect. They're built to last, of course, and are also built to be incredibly efficient, quiet, lightweight and corrosion-resistant. All of this adds up to a pump that is highly cost effective and suited for a wide range of commercial water applications.

At the heart of the EQ's extraordinary performance is its unique impeller design. It provides two significant benefits. First, it means more efficient performance — the EQ pump moves more water more quickly than comparable pumps. And secondly , it means the pump's motor doesn't have to work as hard and, as a result, runs cooler and lasts considerably longer.

What's more, the Pentair EQ pump has been through a rigorous design, development and testing program so you know it's built to handle the toughest commercial applications for years to come.

A vailable in single and three-phase, 50 and 60 Hz models, the EQ sets the new standard for performance in pumps. No one else in the industry has made a plastic injection-molded pump with performance like this for pool and water applications.

Installation

The following general information describes how to install the EQ Series pump.

Note: Before installing this product, read and follow all warning notices and instructions starting on page ii.

Installing the EQ Series Pump

Only a qualified service person should install the EQ Series pump.

Mechanical Installation and Pressure Testing

Mechanical Installation

1. Carefully remove the pump unit and strainer pot assembly, if included, from its shipping package.

2. The pump will perform best when the suction and return head losses (Total Dynamic Head (TDH)) of the pool

system have been carefully determined and the correct pump model selected to fit these requirements. A pump should be selected to operate near the center of its Performance Curve with as high an efficiency as possible. It is also important that the Net Positive Suction Head Available (NPSHA) be greater than the Net Positive Suction Head Required (NPSHR) at the design flow rate.

3. If it is not possible to determine accurate suction and discharge head losses (Total Dynamic Head (TDH)),

conservative plumbing practices should be strictly adhered to. This would include installing the pump as close to the pool as possible and at approximately the same level as the pool water level. (See page iv., General Installation Information, regarding when a strainer pot assembly is required.) Use large diameter pipe especially on the suction line to keep flow velocities at or below 1.8 meters per second (mps), (6 feet per second (fps)). Flow velocities in the return plumbing should not exceed 3 mps (10 fps). Also keep elbows and tees to a minimum. Installations where the pump is going to be installed more that 3 meters (10 feet) below or 1.5 meters (5 feet) above the pool water level must be evaluated by an experienced professional to ensure that the pump will function correctly.

4. A solid flat foundation should be provided to support the pump. The area should be well drained so that the pump

motor will not be flooded under any circumstances. Ensure that adequate space and lighting around the pump is provided for routine maintenance activities.

NOTE

Do not install the pump motor within 1.5 meters (5 feet) of the inside walls of the pool wall unless the pump bears the UL listing mark. UL listed pumps may be installed within 1.5 meters (5 feet) of the inside walls of a swimming pool, spa or hot tub only if a solid copper bonding conductor not smaller than No. 10 SWG (No. 8 AWG) is connected from a bonding lug 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 1.5 meters (5 feet) of the inside walls of the swimming pool, spa or hot tub.

5. It is good practice for most installations to install a valve on both the suction and return line so that the pump can

be isolated for routine maintenance. However, 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 pipe diameter. (i.e. 15.2 cm (6”) pipe requires a 7.6 meters (30 “) straight run in front of the suction inlet of the pump.)

the concrete by using the holes on the outside of the motor supports.

9. Ensure that the flange gasket is properly positioned between the suction flange of the pump and the flange of the suction piping. Use only high quality rubber, full diameter flange gaskets with holes for the bolts to pass through. It may be necessary to hold the gasket in place with either silicone or two or three drops of a cyanoacrylate (super glue) material. Do not use any other grease or glue as they may contain chemicals that could attack the plastic material. Install the flange bolts hand tight on the suction side of the pump.

CAUTION — On installations where the pump is installed without a strainer pot, use only 15.2 cm

(6”) Schedule 40 PVC pipe when making the final flange connection. Do NOT use Schedule 80 Pipe, as this can cause interference with the pump housing.

CAUTION — Use large diameter flat washers between the hex nut and the pump flanges to properly

distribute the clamping forces on the flange. Tighten the flanges to 27.1 newton/ meters (20 ft.-lb.) unless otherwise specified by the flange manufacturer. If it is not possible to use a torque wrench then care should be taken not to over tighten the flange bolts. Failure to follow the above instructions can result in damaging the pump flange.

10. Properly insert the flange gasket on the discharge port of the pump. Install the flange bolts hand tight on the discharge flange connection.

11. Inspect both the suction and flange connection to ensure alignment remains acceptable. Take any corrective action before tightening the flange bolts to the required torque.

CAUTION — Suction and discharge piping must be supported by an appropriate system of supports

or hangers. Inadequately supported pipe can cause excessive loads to be transmitted to the pump resulting in a structural failure of the pump that could result in flooding and property damage.

EQ Series Pump Installation and User’s Guide

Pressure Testing

Certain local codes require that the circulation system be pressure tested with a proof pressure before being commissioned into service or before allowing construction to progress to the next stage.

WARNING — Improperly pressure testing a circulation system can involve significant risk of

property damage or severe personal injury or death. Circulation systems store energy when pressure tested due to the elastic nature of the materials used in construction and due to the compressibility of air that may be contained in the system. The instructions below should be considered a guide only. Each installation should be considered a unique situation that should be carefully investigated for risk.

WARNING — Never test this equipment with air pressure even if specified by the local code. Even

low levels of air pressure result in tremendous storage of energy that can instantaneously be released if a system failure occurs. This instantaneous release of energy can cause failed components to be accelerated to high velocities and to travel distances of 30.48 meters (100 feet) or more. These components could cause severe personal injury or death if they were to strike a person.

1. Understand the local code. The intent of the code may be to ensure that the piping system with its many bonded

joints is leak free. Piping systems typically have a higher pressure capability than the other system components such as the pump or filter. Do not pressure test the pump unless the code specifically requires this.

2. Verify that each component in the system is designed to meet the local code test pressure. Most components

should be marked with a maximum operating pressure. If a component is not marked consult the Owner’s Instructions that came with the component or consult the manufacturer.

3. Verify that the pressure test will be conducted within the operating temperature listed on the components that

make up the circulation system. If no maximum operating temperature is listed then it may be necessary to review the owner’s manual or contact the manufacturer for this information. It is common practice for plastic components to be pressure rated at 22° C (72° F). and then derated for temperatures greater than this.

4. Use only a high quality pressure gage that is certified to be accurate for the pressure for which the test is going

to be conducted. Do not rely on the pressure gage included with the filtration system as it may not be sufficiently accurate to conduct a pressure test for the system. Please note that the pressure in the system will vary depending on where the pressure is taken due to the weight of the water.

5. Ensure that all air will be evacuated from the system when the water pressure is applied to the system. This

will require that all air bleeders on any equipment are open. It also may be necessary to remove some lids or covers on system equipment such as the pump strainer lid to prevent air from being trapped in the system. In addition, there may be other areas of the circulation system where air may be trapped. Do not connect water pressure to the system until you are certain that air will be totally evacuated.

6. Determine the appropriate location in the system to apply the test water pressure. Consider the place in the

system that will best ensure that all air will be displaced when water is introduced.

EQ Series Pump Installation and User’s Guide

Page 12

Pressure Testing, cont’d.

WARNING — Never exceed the maximum operating pressure or temperature limits of the system

Changes in temperature or barometric pressure can cause the internal test pressure to increase or decrease over time once the system is isolated. A pressure relief device should be installed that would prevent the pressure from exceeding the intended test pressure. Exceeding these limits could result in a component failing under pressure. This instantaneous release of energy can cause failed components to be accelerated to high velocities and to travel distances of 30.48 meters (100 feet) or more. These components could cause severe personal injury or death if they were to strike a person.

7. Slowly apply the water pressure and allow the water to flow out all of the openings intended for air to escape. Close the openings beginning at the lowest level first and progressing to the highest level. Do not close any opening until you are sure that air is completely out of that part of the system.

8. Allow the pressure to slowly build once all of the air openings are closed. Close the valve between the water supply and circulation system to isolate the system from the supply pressure.

9. Monitor the system pressure for a few minutes to ensure that it is stabilized.

WARNING — Due to the potential risk that can be involved it is recommended that the pressure

test be kept to the minimum time required by the local code. Do not allow people to work around the system when the circulation system is under pressure test. Post appropriate warning signs and establish a barrier around the pressurized equipment. If the equipment is located in an equipment room, lock the door and post a warning sign.

Never attempt to adjust any closures or lids or attempt to remove or tighten bolts when the system is pressurized. These actions can result in a separation or failure of system components. This instantaneous release of energy can cause components to be accelerated to high velocities and to travel distances of 30.48 meters (100 feet) or more. These components could cause severe personal injury or death if they were to strike a person.

10. It is normal for the test pressure to drift down slightly during the first few minutes as the circulation system expands under pressure.

11. If the system pressure continues to fall, then bleed off the remaining water pressure in the circulation system and inspect the system for leaks. Look for water on the floor and feel around joints for moisture.

12. Ensure the system is not under pressure before attempting any system adjustments or repairs.

13. Repeat the pressurization sequence once the system leaks have been corrected.

Electrical Requirements

This section describes how to secure and wire the EQ pump.

Electrical Requirements and Field Wiring

NOTE

Do not install the pump motor within 1.5 meters (5 feet) of the inside walls of the pool wall unless the pump bears the UL listing mark. UL listed pumps may be installed within 1.5 meters (5 feet) of the inside walls of a swimming pool, spa or hot tub only if a solid copper bonding conductor not smaller than No. 10 SWG (No. 8 AWG) is connected from a bonding lug 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.

CAUTION — To prevent possible voltage reduction that cause flicker sensations in lighting

equipment, this product should be powered by a dedicated power line capable of providing at least 32 A per phase. Other eqipment connected to the same power line may experience operations problems caused by the inrush current during startup of this product.

CAUTION — This pump is for use with permanently installed 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 may be readily disassembled for storage and reassembled to its original integrity.

WARNING —Risk of electrical shock or electrocution.

Always disconnect power to the pool pump at the circuit breaker before servicing the pump. Failure to do so could result in death or serious injury to serviceman, pool users or others due to electric shock.

1. Ensure that the electrical service is disconnected, properly tagged and locked out before working on the pump.

2. Carefully review the motor label. Take note of the important nameplate information such as volts, amps, phase,

HP and code. Most pump models may be field connected so that they can operate on two different voltage circuits. Use extreme care in reviewing the motor wiring diagrams and always verify the voltage of the electrical supply circuit.

3. Carefully review the electrical supply circuit to ensure that it is adequate to meet the pump requirements

identified on the motor nameplate. An electrical code letter is identified on the motor nameplate that identifies the load characteristics of the motor.

EQ Series Pump Installation and User’s Guide

Page 14

Electrical Requirements and Field Wiring, cont’d.

CAUTION — Some single-phase pumps may contain an internal thermal protector designed to

temporarily stop the pump if the motor exceeds a preset temperature. The pump will automatically restart when the motor temperature falls to a preset limit. Always disconnect power before working on the pump to eliminate the possibility that the pump could start unexpectedly.

Three-phase pumps do not contain an internal thermal protector and must be externally protected by an appropriately sized protective device commonly referred to as a starter. Improper sizing of the starter can result in the motor being destroyed or in frequent tripping of the starter.

4. It is important that all portions of the electrical circuit including the conductors that connect the electrical panel to the pump motor are properly sized based on the nameplate information on the pump.

5. Following the National Electrical Code and any local electrical codes connect the grounding conductor and electrical supply conductors to the motor. Ensure that the pump is properly grounded per the above codes utilizing the grounding screw identified in the terminal box of the pump motor.

6. It will be necessary to confirm that the rotation of the motor is in the correct direction on all three-phase pump units and on certain single-phase pump units. Check wiring diagram to determine if motor can be field wired to rotate in both directions. Checking rotation by energizing the pump for one second and then watching the rotation through the back of the motor as it coasts to a stop. Ensure that the rotation matches the direction arrow on the pump. Operating a pump with the incorrect rotation can cause many problems including poor priming, diminished water flow, excessive noise, overloading of the motor and premature failure of the pump.

NOTICE: Due to wide variation in electrical equipment, power equipment, power supply, and installation requirements,

this manual does not make specific recommendations concerning auxiliary equipment or fusing /wiring.

Wire sizing, wire type, branch circuit fuse protection, motor starter, control equipment, and related items must meet National Electrical Code and local code requirements.

Motors are supplied by several manufacturers and nameplate data (service factor, maximum amperage, etc.) will vary. Consult control manufacturer and motor nameplate on your pump to correctly choose and size motor starter and control equipment for your particular installation. Specific electrical questions or problems should be addressed to the manufacturer of the electrical component in question.

Voltage/Phase

Voltage at motor must be not more than 10% above or below motor nameplate rated voltage or motor may overheat, causing overload tripping and reduced component life. If voltage is less than 90% or more than 110% of rated voltage when motor is running at full load, consult power company.

Do not try to connect 3-phase motors to single phase power supply or single phase motors to 3-phase power supply.

Emergency Shutoff

Install an Emergency Shutoff Switch near pool. Clearly mark this switch and mount it in a location that is accessible to bathers or pool operating personnel (e.g. lifeguards). Make sure that all lifeguards and pool personnel understand the switch’s use in case of emergency (entrapment, electrical malfunction, etc.).

CAUTION — Always fill the pump with water before energizing the pump motor. Operating the

pump without water can damage the pump seal within a few seconds.

EQ Series Pump Installation and User’s Guide

Section 4

Initial Operation of Pump

This section describes how to prime the EQ pump.

WARNING —Do not operate the pump until you have read and understand clearly all the operating instructions

and warning messages for all equipment that is a part of the pool circulating system. The following instructions are intended as a guide for initially operating the pump in a general pool installation, however each installation may have unique conditions where the starting procedure could be different. Failure to follow all operating instructions and warning messages can result in property damage or severe personal injury or death.

1. Relieve any pressure that may be trapped in the circulation system.

2. Open all air relief devices on any equipment in the system.

3. Open the appropriate valves on the suction and discharge plumbing. If the pump is installed below the water

level of the pool, water will flow into the pump. If the pump is installed above the water level it will be necessary to fill the strainer pot with water up to the suction pipe connection.

WARNING —The strainer pot may be at a pressure that is higher or lower than the atmospheric pressure.

Always open the drain plug on the strainer pot and allow for the pressure to equalize before removing the locking ring. Attempting to remove the locking ring before the pressure is equalized may result in a rapid exchange of pressure. This instantaneous release of energy can cause components to be accelerated to high velocities and to travel distances of 30.5 meters (100 feet) or more. These components could cause severe personal injury or death if they were to strike a person.

4. Stand clear of all equipment and energize the pump.

5. The pump will experience a temporary unstable condition as water and air flow through the pump. During this

unstable condition the pump may be noisy and produce erratic flow. If the pump is below or at water level this temporary unstable condition should last only a few seconds.

6. If the pump is installed above the pool water level then the pump must remove the air from the suction piping.

This phase of pump operation is referred to as priming. Pumps that are labeled self-priming have demonstrated in a test laboratory that they can prime when installed 3 meters (10 feet) above the pool water level in a time not exceeding 45 minutes. (Exception: Models EQW300 1PH and EQW300 3 PH may require up to 1 hour and 15 minutes to prime to 3 meters (10 feet). Disconnect power to the pump if it does not prime within the time indicated. A pump that will not prime usually indicates a system problem such as an air leak on the suction side of 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 personal injury make sure the strainer pot temperature has cooled to room temperature. Carefully remove the drain plug on the strainer pot and allow the pressure to equalize before removing the locking ring.

7. It is important that once the pump has primed and is operating in a stable manner that the voltage be measured

at the pump when first put into service. If the electrical supply circuit is inadequate a voltage drop may occur when the pump is operating under load. The pump will operate most efficiently when operated at the nameplate voltage. Operating the pump at more than 10% above or below the voltage listed on the nameplate could result in the pump not operating properly and may damage the pump motor.

Maintenance

Cleaning of the Strainer Basket

1. The pump is designed to be maintenance free with the exception of requiring a periodic cleaning of the strainer

basket.

2. A routine inspection should be done by visually looking through strainer lid for debris while the pump is in

operation. The strainer basket should be cleaned when approximately 25 % blocked. Allowing the strainer basket to become excessively blocked will diminish water flow, reduce pump efficiency, cause cavitation and may damage the basket or other pump components.

3. Disconnect power to the pump before cleaning the basket.

4. Close isolation valves on the suction and discharge lines if necessary to prevent flooding.

WARNING — The strainer pot may be at a pressure that is higher or lower than the atmospheric

pressure. Always open the drain plug on the strainer pot and allow for the pressure to equalize before removing the locking ring. Attempting to remove the locking ring before the pressure is equalized may result in a rapid exchange of pressure. This instantaneous release of energy can cause components to be accelerated to high velocities and to travel distances of or 30.5 meters (100 feet) or more. These components could cause severe personal injury or death if they were to strike a person.

WARNING — If the pump has been energized for a period greater than 45 minutes without water

flowing through the pump for any reason, the water in the strainer pot may be hot. Attempting to remove the locking ring without removing the drain plug in the pot and allowing the pressure to equalize may result in the hot water rapidly escaping and causing severe personal injury.

5. Open the drain plug in the strainer pot and allow the pressure to completely stabilize.

6. Remove the locking ring and the clear lid from the strainer pot.

7. Remove the basket and dispose of the debris. Use a water hose and soft brush to remove debris blocking the

openings in the basket if required.

8. Replace the basket making sure it is properly oriented.

9. Replace the lid, by aligning the four tabs with the tabs on the strainer pot and making sure the O-ring is clean

and is properly located in the groove of the lid.

10. Secure the lid in place by tightening the locking ring hand tight only. Do not over tighten the locking ring as that will make removal difficult.

WARNING — It is recommended that only water and a soft cloth be used to clean the lid and other

pump components. Cleaners may contain chemicals that could damage or weaken pump components causing them to fail and allowing an instantaneous release of energy. This instantaneous release of energy can cause components to be accelerated to high velocities and to travel distances of 30.5 meters (100 feet) or more. These components could cause severe personal injury or death if they were to strike a person.

Preventative Maintenance

It may be possible to extend the life of the pump and to prevent a pump down situation by implementing a preventative maintenance program. This may be done by periodically performing a list of activities and recording certain information to be able to spot potential problems before they become serious. It is recommended that these activities be performed after the filter cleaning procedure so that the information will be taken from the same baseline each time. All or part of the following activities could provide the foundation for a preventative maintenance program.

1. Record the time it takes for the pump to prime and come to a stable operating condition. Increased priming times can indicate a problem. See Section 7, Troubleshooting.

2. Observe the sound coming from the pump housing. A substantial change in sound from inside the pump is a clue that something in the circulation system has changed.

3. Observe the sound coming from the motor. Motor bearings rarely fail without first becoming noisy.

4. Observe the temperature of the motor. The motor is designed to carry the pump load without building up excessive heat. An increase in normal operating temperatures may indicate a potential problem. A thermocouple placed at the motor ventilation discharge opening may be used to monitor motor temperature. It normally takes about 1 hour for the motor temperature to stabilize. See Section 7, Troubleshooting.

5. Record any flow and pressure readings on the circulation system meters and gages. See Section 7, Troubleshooting.

6. Record supply voltage and amps. Supply voltage can change throughout the day depending on other electrical loads in the area. Changes in supply voltage will affect the amp draw and water output of the pump.

7. Inspect the floor around the pump to ensure there are no indications of leaks. Address leaks immediately. A mechanical seal leak is indicated by water dripping between the motor and the motor adaptor. A mechanical seal leak can result in a failed motor bearing.

8. Inspect the exterior pump components for any sign of a structural failure. Most structural failures will start with a hairline crack that originates from a corner where two different shapes intersect.

9. Verify that the support brackets or hangars for the suction and discharge piping are continuing to fully support the weight of the piping.

WARNING —Risk of electrical shock or electrocution.

Always disconnect power to the pool pump at the circuit breaker before servicing the pump. Ensure that the disconnected circuit is locked out or properly tagged so that it cannot be switched on while you are working on the pump. Failure to do so could result in death or serious injury to serviceman, pool users or others due to electric shock.

Read all servicing instructions before working on the pump.

Section 6

Servicing

The pump is designed to allow for quick servicing of any moving parts without disturbing the plumbing connections. The pump can be serviced with the common tools that are in nearly every service persons toolbox. The following sequential instructions are for a complete disassembly in order to replace a failed motor . The same instructions may be used to perform a partial disassembly to replace any internal component, but following all steps will not be required.

CAUTION — It is recommended that you replace the motor with the Pentair replacement motor as

identified in Section 8. This motor has been thoroughly tested to ensure that it will function appropriately with the pump under a wide variety of operating conditions. If you choose to use another replacement motor it is important that the frame type, the HP, the service factor, the voltage, the phase and the motor speed match exactly to that listed on the original motor. Slight differences in these parameters can cause the motor to not fit the pump correctly or cause the motor to fail prematurely.

Disassembly

1. Ensure the electric supply circuit is disconnected and is properly tagged and locked out.

2. Disconnect the line supply conductors and the ground conductor from the motor (1) if the motor is being replaced.

3. Close any valves required to prevent flooding when the pump is disassembled.

4. Review the parts breakdown in Section 8, to understand how the pump components are assembled together.

5. Remove the pump housing (22) drain plug (24) and allow the pump to completely drain.

6. Remove the four 5/8 in. hex nuts (23) that secure the motor end assembly to the front housing (22).

7. If the motor support (2) is bolted to a permanent surface it will be necessary to remove the screws (6) that are securing the motor to the motor support (2) to allow for removal of the motor end assembly.

8. Grasp the motor end assembly and pull backwards. It may be necessary to wiggle the motor assembly from side to side to break free the O-Ring seals inside the pump.

9. Pull the motor end assembly free of the housing (22) so that there is adequate access to the internal components. If desired, the supply conductors can be disconnected and the motor end assembly can be taken to a workbench for easier service.

10. Remove the four screws (20) with washers (18) (19) that secure the diffuser (17) to the seal plate (13).

11. Hold the impeller (15) nose and remove the screw (16) and washers (4) (5) that secure the impeller (15).

12. The impeller (15) is also secured to the shaft by a parallel key . The impeller (15) can be freed from the

shaft and key by grasping the outside of the impeller (15) and pulling the impeller (15) away from the motor (1). It is good practice to inspect the impeller (15) to ensure that the vane passageways are open and that no vanes have been substantially broken or worn.

13. Removing the impeller (15) will expose the two pieces of the mechanical seal (14). It will not be necessary to further disassemble the pump if only a seal replacement is required.

14. The seal plate (13) is attached to the motor adaptor (7) by two dowel pins (26). The seal plate (13) can be freed from these dowel pins (26) by grasping the outside of the seal plate (13) and pulling way from the motor wiggling it from side to side if required.

15. Remove the four screws (10) with washers (8) (9) that secure the motor adaptor (7) to the motor (1). These components could cause severe personal injury or death if they were to strike a person.

Assembly

1. Ensure that the two 6 ½ in. long screws (11) with washers (12) are properly inserted into the bottom of the

motor adaptor (7) before attaching the motor adaptor (7) to the new motor (1).

2. Properly orient the motor adaptor (7) to the motor (1) and secure in place using the four screws (10) and

washers (8) (9).

3. Insert the two dowel pins (26) into the motor adaptor (7).

4. Install the stationary ring of the mechanical seal (14) into the seal plate bore. Ensure that it is fully inserted into

the bore with the white surface facing you.

CAUTION — The mechanical seal is a highly engineered component that must be carefully handled. The

contact faces are manufactured to extremely precise tolerances. These faces must be free of all surface dust and debris. Always wash your hands before handling the mechanical seal. Avoid touching the contact faces except for when pressing the seal ring into the bore. Lubricate the rubber portion with a slight amount of soapy water if required to insert it into the bore. Do not use silicone or other lubricants as this can contaminate the seal face. Rinse the seal face if required after assembly to free it of any dirt or debris.

5. Properly orient the seal plate (13), slip it onto the two dowel pins (26) and secure to the motor adaptor (7) by

tapping it toward the motor adaptor (7) until there is no clearance between the two parts.

6. Slip the spring portion of the mechanical seal (14) over the motor shaft, being certain that the hard black

contact surface is facing the white surface of the stationary seal ring. Use a small amount of soapy water if required to lubricate the rubber of the mechanical seal (14) so that it slips easily over the shaft.

7. Install the shaft key into the shaft of the motor and then install the impeller (15) over the shaft. It will be

necessary to align the keyway in the impeller (15) with the key . Push the impeller (15) as far as possible onto the motor shaft (1).

8. Install the socket head screw (16) with washers (4) (5) to secure the impeller (15). It is important that the

screw (16) be tightened securely and that the impeller (15) is fully seated.

9. Apply a light film of silicone grease to the inside diameter of the brass bushing inside the diffuser (17). This

film will assist in properly centering the diffuser bushing to the impeller (15) and will reduce the friction should the parts contact during motor start-up. DO NOT USE ANY OTHER TYPES OF LUBRICANTS.

10. Install the diffuser (17) over the impeller (15) and secure with the four screws (20), but only hand tight. The diffuser (17) has clearance around the four screws (20) that will allow adjustment of the fit of the diffuser (17) around the impeller (15) nose. Rotate the impeller (15) by hand to ensure that it is free to turn and slowly tighten each of the four screws (20). Verify that the impeller (15) is free to turn once the diffuser screws (20) are fully tightened.

11. Lubricate the diffuser O-Ring (21) and the larger seal plate O-Ring (28) with silicone lubricant or Murphy Soap. This will allow the O-Rings to slip into place without getting pinched. Ensure that the big seal plate O-Ring (28) is properly seated on the large diameter of the seal plate (13).

12. Carefully slip the motor end assembly into the housing (22) pushing it forward as far as possible until the large seal plate O-Ring (28) comes into contact with the housing (22). Insert the four 6½ in. long screws (11) through the housing (22) and secure the assembly in place using the washers (12) and nuts (23). Gradually tighten each of the four screws a few turns in a crossing pattern to ensure that the motor assembly is properly centered to the housing.

Do not over tighten these screws.

Oil

CAUTION — Failure to follow the above assembly procedures could cause the impeller to bind once the

pump is fully assembled. It is possible to remove the strainer basket, reach through the strainer pot and spin the impeller to verify that it will rotate freely. A bound impeller may cause the motor to not start or cause the motor to draw excessive amps.

13. Secure the motor (1) to the motor supports (2).

14. Reconnect the ground and supply conductors.

15. Read and follow the instructions under

Section 4, Initial Operation of Pump before putting the pump back into service.
