1.1 Safety Instructions

All electrical work must be performed by a licensed electrician and conform to all national, state, and local codes. When installing and using this electrical equipment, basic safety precautions should always be followed, including the following:

⚠ WARNINGRISK OF SUCTION ENTRAPMENT HAZARD, WHICH, IF NOT AVOIDED, CAN RESULT IN SERIOUS INJURY OR DEATH. Do not block pump suction, as this can cause severe injury or death. Do not use this pump for wading pools, shallow pools, or spas containing bottom drains, unless the pump is connected to at least two (2) functioning suction outlets. Drain covers must be certified to the latest published edition of ANSI/ASME A112.19.8, or its successor standard ANSI/APSP-16.

⚠ WARNINGTo reduce the risk of injury, do not permit children to use this product.

⚠ WARNINGTo reduce the risk of property damage or injury, do not attempt to change the backwash (multiport, slide, or full flow) valve position with the pump running.

⚠ WARNINGJandy Pro Series Pumps are powered by a high-voltage electric motor and must be installed by a licensed or certified electrician or a qualified swimming pool service technician.

⚠ WARNINGDue to the potential risk of fire, electric shock, or injuries to persons, Jandy Pro SeriesPumps must be installed in accordance with the National Electrical Code® (NEC®), all local electrical and safety codes, and the Occupational Safety and Health Act (OSHA). Copies of the NEC may be ordered from the National Fire Protection Association, 470 Atlantic Ave., Boston, MA 02210, or from your local government inspection agency.

⚠ WARNINGRISK OF ELECTRIC SHOCK, FIRE, PERSONAL INJURY, OR DEATH. Connect only to a branch circuit that is protected by a ground-fault circuit-interrupter (GFCI). Contact a qualified electrician if you cannot verify that the circuit is protected by a GFCI. Make sure 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 electrical shock. Do not use the device. Disconnect the device and have the problem corrected by a qualified service representative before using.

⚠ WARNINGIncorrectly installed equipment may fail, causing severe injury or property damage.

⚠ WARNINGDo not connect system to an unregulated city water system or other external source of pressurized water producing pressures greater than 35 PSI.Trapped air in the system can cause the filter lid to be blown off, which can result in death, serious personal injury, or property damage. Be sure all air is out of the system before operating.

WARNING

To minimize risk of severe injury or death, the filter and/or pump should not be subjected to the piping system pressurization test.

Local codes may require the pool piping system to be subjected to a pressure test. These requirements are generally not intended to apply to the pool equipment, such as filters or pumps.

Jandy Pro Series pool equipment is pressure tested at the factory.

If, however, the WARNING cannot be followed and pressure testing of the piping system must include the filter and/or pump, BE SURE TO COMPLY WITH THE FOLLOWING SAFETY INSTRUCTIONS:

• Check all clamps, bolts, lids, lock rings, and system accessories to ensure they are properly installed and secured before testing.
• RELEASE ALL AIR in the system before testing.
  • Water pressure for test must NOT EXCEED 35 PSI.
  • Water temperature for test must NOT EXCEED 100°F (38°C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready for operation.

Notice: These parameters apply to Jandy Pro Series equipment only. For non-Jandy Pro Series equipment, consult the equipment manufacturer.

WARNING

Chemical spills and fumes can weaken pool/spa equipment. Corrosion can cause filters and other equipment to fail, resulting in severe injury or property damage. Do not store pool chemicals near your equipment.

CAUTION

Do not start pump dry! Running the pump dry for any length of time will cause severe damage and will void the warranty.

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.
• Do not install beneath the skirt of a hot tub. The pump requires adequate ventilation to maintain air temperature at less than the maximum ambient temperature rating listed on the motor rating plate.
• For Canadian installation, this pump carries a Type 3R enclosure rating and therefore is not intended for installation in areas subjected to windblown dust.

1.2 Pool Pump Suction Entrapment Prevention Guidelines

WARNING

SUCTION HAZARD. Can cause serious injury or death. Do not use this pump for wading pools, shallow pools, or spas containing bottom drains, unless pump is connected to at least two (2) functioning suction outlets.

WARNING

Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or operate swimming pools, spas, or hot tubs if a suction outlet cover is missing, broken, or loose.

The following guidelines provide information for pump installation that minimizes risk of injury to users of pools, spas, and hot tubs:

Entrapment Protection - The pump suction system must provide protection against the hazards of suction entrapment.

Suction Outlet Covers - All suction outlets must have correctly installed, screw-fastened covers in place. All suction outlet (drain) covers must be maintained. Drain covers must be listed/certified to the latest published edition of ANSI/ASME A112.19.8, or its successor standard ANSI/APSP-16. They must be replaced if cracked, broken, or missing.

Number of Suction Outlets Per Pump - Provide at least two (2) hydraulically-balanced main drains, with covers, as suction outlets for each circulating pump suction line. The centers of the main drains (suction outlets) on any one (1) suction line must be at least three (3) feet apart, center to center. See Figure 1 on page 7.

The system must be built to include at least two (2) suction outlets (drains) connected to the pump whenever the pump is running. However, if two (2) main drains run into a single suction line, the single suction line may be equipped with a valve that will shut off both main drains from the pump. The system shall be constructed such that it shall not allow for separate or independent shutoff or isolation of each drain. See Figure 1 on page 7.

More than one (1) pump can be connected to a single suction line as long as the requirements above are met.

Water Velocity - The maximum water velocity through the suction fitting or cover for any suction outlet must be 1.5 feet per second, unless the outlet complies with the latest published edition of ANSI/ASME A112.19.8, the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications, or its successor standard ANSI/APSP-16. In any case, do not exceed the suction fitting's maximum designed flow rate.

If 100% of the pump's flow comes from the main drain system, the maximum water velocity in the pump suction hydraulic system must be six (6) feet per second or less, even if one (1) main drain (suction outlet) is completely blocked. The flow through the remaining main drain(s) must comply with the latest published edition of ANSI/ASME A112.19.8, the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications, or its successor standard ANSI/APSP-16.

Testing and Certification - Suction outlet covers must have been tested by a nationally recognized testing laboratory and found to comply with the latest published edition of ANSI/ASME A112.19.8, the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications, or its successor standard ANSI/APSP-16.

Fittings - Fittings restrict flow; for best efficiency use fewest possible fittings (but at least two (2) suction outlets).

Avoid fittings that could cause an air trap.

Pool cleaner suction fittings must conform to applicable International Association of Plumbing and Mechanical Officials (IAPMO) standards.

Section 2. General Description

2.1 Introduction

This manual contains information for the proper installation, operation, and maintenance of Jandy Pro Series ePump Series variable-speed pumps. Procedures in this manual must be followed exactly. To obtain additional copies of this manual, contact Zodiac® Customer Support at 800.822.7933 or visit our website at www.zodiacpoolsystems.com. For address information, see the back cover of this manual.

2.2 Description

The ePump is a variable-speed pump that can be run from 600 RPM to 3450 RPM. When connected to the Jandy Pro Series ePump controller, up to eight (8) speed settings may be programmed and recalled. This allows you to select the most appropriate speed for your application. Even more versatile programming is possible when you use a Jandy Pro Series AquaLink ^® RS controller.

The Jandy Pro Series ePump is designed to meet the needs of today's more hydraulically demanding pool equipment. The pump housing, backplate, diffuser, impeller, and hair and lint pot (pump debris filter basket) are all made from high quality thermoplastic materials. These materials were chosen for their strength and corrosion resistance.

The pump is driven by an electric motor directly attached to the pump impeller. As the electric motor turns, it causes the impeller to turn, which forces water to flow through the pump. The water flows through the pump inlet and then into the filter basket. The basket assembly pre-strains/traps large particles. The water then enters the center of the pump housing, flows through the impeller into the diffuser, and flows out the pump discharge port.

Section 3. Installation Information

3.1 Plumbing

3.1.1 Preparation Information

1. Upon receipt of the pump, check the carton for damage. Open the carton and check the pump for concealed damage, such as cracks, dents or a bent base. If damage is found, contact the shipper or distributor where the pump was purchased.

2. Inspect the contents of the carton and verify that all parts are included. See Section 7.1, Replacement Parts List and Exploded View.

3.1.2 Pump Location

CAUTION

For Canadian installation, this pump carries a Type 3R enclosure rating and therefore is not intended for installation in areas subjected to windblown dust.

1. Zodiac recommends installing the pump within one (1) foot above water level. Refer to Figure 2 for a typical installation. The pump should not be elevated more than a few feet above the water level of the pool. A check valve is recommended on the suction line to the pump.

WARNING

To Reduce the Risk of Fire, install pool equipment in an area where leaves or other debris will not collect on or around the equipment. Keep surrounding area clear of all debris such as paper, leaves, pine-needles and other combustible materials.

WARNING

Some Safety Vacuum Release System (SVRS) devices are not compatible with the installation of check valves. If the pool has an SVRS device, be sure to confirm that it will continue to safely operate when any check valves are installed.

NOTE To achieve better self-priming, install the pump as close as possible to the water level of the pool.

1. If the pump is located below water level, isolation valves must be installed on both the suction and return lines to prevent back flow of pool water during any routine or required servicing.

2. The pump and other circulation equipment must be located more than five (5) feet from the water. Choose a location that will minimize turns in the piping.

NOTE In Canada, the pump must be located a minimum of three (3) meters (approximately 10 feet) from the water (CSA C22.1).

1. The pump should be installed on a firm, solid, and level surface to avoid risk of settlement. Do not use sand to level the pump as sand will wash away. Check local building codes for any additional requirements (Ex. Equipment pads in Florida must be concrete and equipment must be secured to the pad.)

NOTE Zodiac Pool Systems, Inc. recommends bolting the pump directly to the foundation.

1. The pump foundation must have adequate drainage to prevent the motor from getting wet. Protect the pump from the rain and sun.

2. Proper ventilation is required for the pump to operate normally. All motors generate heat that must be removed by providing proper ventilation.

3. Provide access for future services by leaving a clear area around the pump. Allow plenty of space above the pump to remove the lid and basket for cleaning.

4. If the equipment is in a potentially dark area, provide adequate lighting.

3.1.3 Pipe Sizing

NOTE All HP ratings given in this section apply to full-rated pumps.

3.1.3.1 Suction Pipe

When the pump is located up to 50 feet from the pool, the recommended minimum pipe size for the suction side of the pump is 2" for .75 to 1.5 HP*. For 2.0 HP* pumps, the recommended pipe size is 2 ½". For 3.0 HP* pumps, the recommended pipe size is 3". *HP refers to full rated pumps.

When the pump is located up to 50 feet from the pool, the recommended minimum pipe size for the discharge side of the pump is 2" for .75 to 1.5 HP*. For 2.0 HP* pumps, the recommended pipe size is 2½". For 3.0 HP* pumps, the recommended pipe size is 3". *HP refers to full rated pumps.

NOTE All pipe sizes are able to withstand the pressures the pump will deliver, but not necessarily the flow. If the pipe is too small for the pump, or is elevated above water, the maximum gallons per minute (GPM) may not be delivered. If this happens, the pump will develop a pocket of air (cavitation) that makes noise. This may shorten the life of the pump.

3.1.3.3 Installation Recommendations

1. If the pump is located below water level, isolation valves must be installed on both sides of the pump to prevent the back flow of pool water during any routine or required servicing.

Figure 2. Typical Piping Installation

1. To help prevent difficulty in priming, install the suction pipe without high points (above inlet of pump - inverted "U"s, commonly referred to in plumbing as an airlock) that can trap air. For installations of equipment up to 100 feet from the water, refer to Table 1, the pipe sizing chart. For installations of equipment more than 100 feet from the water, the recommended pipe size must be increased to the next size.

Table 1. Pipe Sizing Chart for Schedule 40 PVC

Pipe Size	Maximum Flow Suction(6 feet per second)	Maximum Flow Discharge(8 feet per second)
1 12 " 37	GPM (140 LPM) 50 GPM	(189 LPM)
2" 62	GPM (235 LPM) 85 GPM	(322 LPM)
2 12 " 88	GPM (333 LPM) 120 GPM	(454 LPM)
3" 136	GPM (515 LPM) 184 GPM	(697 LPM)
4" 234	GPM (886 LPM) 313 GPM	(1185 LPM)

1. ePump™ Series Pumps come equipped with unions on both the suction and discharge ports. This feature simplifies installation and service and eliminates the possibility of leaks at threaded adapters.

2. The Jandy Pro Series ePump must be connected to at least two (2) hydraulically-balanced main drains (suction outlets) for each pool pump suction line. Refer to Figure 2. Each drain must be provided with covers that are listed or certified to the latest published edition of ANSI/ASME A112.19.8, or its successor standard ANSI/APSP-16. The suction outlets of the main drains must be at least three (3) feet apart or at different planes. The suction outlets

can be a drain and skimmer, two (2) drains, two (2) skimmers, or a skimmer with an equalizer line installed. For additional details and guidelines, refer to ANSI/APSP 7, the standard for Suction Entrapment Avoidance in Swimming Pools, Wading Pools, Spas, Hot Tubs, and Catch Basins. Check the local codes for proper installation requirements. Applicable local codes will take precedence over other codes.

NOTE To prevent entrapment, the system must be built so it cannot operate with the pump drawing water from only one (1) main drain. At least two (2) main drains must be connected to the pump when it is in operation. However, if two (2) main drains run into a single suction line, the single suction line may be equipped with a valve that will shut off both main drains from the pump.

1. The piping must be well supported and not forced together where it will experience constant stress.

2. Always use properly sized valves. Jandy Pro Series Diverter Valves and Jandy Pro Series Ball Valves typically have the best flow capabilities.

3. Use the fewest fittings possible. Each additional fitting has the effect of moving the equipment farther away from the water.

NOTE If more than ten suction fittings are needed, the pipe size must be increased.

1. Every new installation must be pressure tested according to local codes.

3.2 Electrical Installation

3.2.1 Voltage Checks

The correct voltage, as specified on the pump data plate, is necessary for proper performance and long motor life. Incorrect voltage will decrease the pump's ability to perform and could cause overheating, reduce the motor life, and result in higher electric bills.

It is the responsibility of the electrical installer to provide data plate operating voltage to the pump by ensuring proper circuit sizes and wire sizes for this specific application.

CAUTION

Failure to provide data plate voltage (within 10%) during operation will cause the motor to overheat and void the warranty.

3.2.2 Bonding

1. The motor frame must be bonded to a reliable grounding point using a solid copper conductor, No. 8 AWG or larger. In Canada, No. 6 AWG or larger must be used. If the pump is installed within five (5) feet (1.5 m) of the inside walls of the swimming pool, spa, or hot tub, the motor frame must be bonded to all metal parts of the swimming pool, spa, or hot tub structure and to all electrical equipment, metal conduit, and metal piping within five (5) feet (1.5 m) of the inside walls of the swimming pool, spa, or hot tub.

2. Bond the motor using the provided external lug. See Figure 3.

WARNING

Always disconnect the power source before working on a motor or its connected load.

WARNING

In order to avoid the risk of property damage, severe personal injury, and/or death, make sure that the control switch, time clock, or control system is installed in an accessible location, so that in the event of an equipment failure or a loose plumbing fitting, the equipment can be easily turned off.

Figure 3. Bonding the Motor, Regal Beloit Motor

CAUTION

The pump must be permanently connected to a dedicated electrical circuit. No other equipment, lights, appliances, or outlets may be connected to the pump circuit, with the exception of devices that may be required to operate simultaneously with the pump, such as a chlorinating device or heater.

3.2.3 Electrical Wiring

1. The pump motor must be securely and adequately grounded using the green screw provided. Ground before attempting to connect to an electrical power supply. Do not ground to a gas supply line.

2. Wire size must be adequate to minimize voltage drop during the start-up and operation of the pump. See Table 2 for suggested wire sizes.

3. Insulate all connections carefully to prevent grounding or short-circuits. Sharp edges on terminals require extra protection. For safety, and to prevent entry of contaminants, reinstall all conduit and terminal box covers. Do not force connections into the conduit box.

3.4.1 Replace Blue Pressure Test O-ring if Necessary

If you open the pump lid before conducting the pressure test, the blue o-ring will probably fall out. If this happens, you will need to install it on the lid again before conducting pressure testing.

There is a risk of damage to the blue o-ring during re-installation. If you damage it when trying to re-install it, you will need to order a new blue pressure test o-ring before you begin conducting the pressure test.

These instructions describe the proper procedures for replacing, using, and disposing of the blue o-ring.

These instructions must be followed exactly. Read through the instructions completely before starting the procedure.

1. Make sure that the pump is turned off.
2. Make sure that the switch to the circuit breaker that powers the pump motor is turned off.

WARNING ELECTRICAL SHOCK HAZARD

Turn off the pump and the main breaker in the pump electrical circuit before starting the procedure. Failure to comply may cause a shock hazard, resulting in severe personal injury or death.

WARNING ELECTRICAL SHOCK HAZARD

Due to the potential risk of fire, electric shock, or injuries to persons, Jandy Pro Series Pumps must be installed in accordance with the National Electrical Code® (NEC®), all local electrical and safety codes, and the occupational Safety and Health Act (OSHA). Copies of the NEC may be ordered from the National Protection Association, 470 Atlantic Ave., Boston, MA 02210, or from your local government inspection agency.

In Canada, Zodiac Pumps must be installed in accordance with the Canadian Electrical Code (CEC).

1. Make sure all necessary isolation valves are closed to prevent pool water from reaching the pump.
2. Following the markings on the locking ring, turn the ring counter-clockwise until the 'START' markings align with the ports.
3. Carefully remove the lid with locking ring.

3.4.1.2 Replace Blue O-ring

1. Turn the lid with locking ring upside down and place it on a stable surface.
2. Place the blue o-ring on the step located 14 " from the bottom of the lid. See Figure 8.
3. Make sure that the o-ring is properly seated. It helps to "place" the o-ring on the step rather than to "roll" it on. That prevents it from rolling off.

NOTE The blue o-ring sits approximately 14 " away from the seal. See Figure 8.

1. Carefully install the lid, making sure that the blue pressure test o-ring sits in the housing without "binding" or "rolling" off.

2. Following the markings on the locking ring, align 'START' markings with the ports and turn clockwise until 'LOCKED' markings align with the ports. Do not tighten past the 'LOCKED' marking.

3.5 Conducting Pressure Test

WARNING

When pressure testing a system with water, air is often trapped in the system during the filling process. This air will compress when the system is pressurized. Should the system fail, this trapped air can propel debris at a high speed and cause injury. Every effort to remove trapped air must be taken, including opening the bleed valve on the filter and loosening the pump basket lid while filling the pump.

WARNING

Trapped air in the system can cause the filter lid to be blown off, which can result in death, serious injury, or property damage. Be sure all air is properly purged out of the system before operating. DO NOT USE COMPRESSED AIR TO PRESSURE TEST OR CHECK FOR LEAKS.

WARNING

Do not pressure test above 35 PSI. Pressure testing must be done by a trained pool professional. Circulation equipment that is not tested properly might fail, which could result in severe injury or property damage.

WARNING

When pressure testing the system with water, it is very important to make sure that the pump basket lid is completely secure.

1. Fill the system with water, using care to eliminate trapped air.
2. Pressurize the system with water to no more than 35 PSI.
3. Close the valve to trap pressurized water in the system.
4. Observe the system for leaks and/or pressure decay.
5. If there are lid leaks, repeat Steps 1-3. For technical support, call 800.822.7933.
6. After successfully completing the test, discard the blue pressure test o-ring.

3.6 Auxiliary Load Operation

Certain pump models are equipped with a terminal bar that provides user access to a built-in Auxiliary Load relay contact. This normally-open, dry contact is activated under certain operating conditions and is primarily intended to be used to control external devices that require system water flow for proper functioning, such as heaters, booster pumps, salt water chlorinators, etc.

See Figures 4, 5A and 5B for compartment's location details. An access cover with Phillips-head screw must be removed before proceeding.

Auxiliary Load Connection Requirements

WARNING

ELECTRICAL SHOCK HAZARD

Due to the potential risk of fire, electric shock, or injuries to persons, Zodiac® Pumps and any auxiliary loads must be installed in accordance with the National Electrical Code® (NEC®), all local electrical and safety codes, and the occupational Safety and Health Act (OSHA). Copies of the NEC may be ordered from the National Protection Association, 470 Atlantic Ave., Boston, MA 02210, or from your local government inspection agency.

In Canada, Zodiac Pumps must be installed in accordance with the Canadian Electrical Code (CEC).

- The Auxiliary Load relay contacts are rated at 230V/11A RMS. Please ensure the requirements of the equipment to be connected to the Auxiliary Load do not exceed this rating.

Auxiliary Load Operation Characteristics

Auxiliary Load relay contact activation is speed-dependent, and behaves as follows:

Contact Closure

From a stopped condition, there is a three-minute delay before the Auxiliary Load contact is closed when the motor speed reaches and maintains a speed of at least 1725 RPM.

From a running condition at below 1725 RPM, there is a five-second delay before the Auxiliary Load contact is closed when the motor speed reaches and maintains a speed of at least 1725 RPM.

Contact Opening

If the pump speed is below 1725 RPM, the Auxiliary Load contact is opened. Contact openings are always immediate.

Section 4. Operation

4.1 Start-up

CAUTION

Never run the pump without water. Running the pump "dry" for any length of time can cause severe damage to both the pump and motor and will void the warranty.

If this is a new pool installation, make sure all piping is clear of construction debris and has been properly pressure tested. The filter should be checked for proper installation, verifying that all connections and clamps are secure according to the manufacturer's recommendations.

WARNING

To avoid risk of property damage, severe personal injury or death, verify that all power is turned off before starting this procedure.

1. Release all pressure from the system and open the filter pressure release valve.

2. Depending on the location of the pump, do one of the following:

3. If the pump is located below the water level of the pool, open the filter pressure release valve to prime the pump with water.

4. If the pump is located above the water level of the pool, remove the lid and fill the basket with water before starting the pump.

5. Prior to replacing the lid, check for debris around the lid o-ring seat. Debris around the lid o-ring seat will cause air to leak into the system and will make it difficult to prime the pump.

6. Hand-tighten the lid to make an air tight seal. Do not use any tools to tighten the lid: hand-tighten only. Make sure all valves are open and the unions are tight.

7. Restore power to the pump. Then turn on the pump by following the instructions in the appropriate manual: ePump Controller Owner's manual, H0311200, AquaLink® RS Owner's Manual, 6593, AquaLink PDA Owner's Manual, H0572300, or AquaLink Z4 Controller Owner's Manual, H0386600.
8. Once all the air has left the filter, close the pressure release valve.

9. The pump should prime. The time it takes to prime will depend on the elevation and length of pipe used on the suction supply pipe. See Section 3.1.3.3, Installation Recommendations, for proper elevation and pipe size.

10. If the pump does not prime and all the instructions to this point have been followed, check for a suction leak. If there is no leak, repeat Steps 2 through 7.

11. For technical assistance, call Zodiac ^® Technical Support at 800.822.7933.

Section 5. Service and Maintenance

5.1 Routine Maintenance

Inspect the pump debris tray basket for debris by looking through the clear pump lid. Remove any debris, because as debris accumulates, it will begin to block the flow of water through the pump. Keep the basket clean to improve the performance of the pump.

1. Turn off the power to the pump. If the pump is located below the water level, close the isolation valves on the suction and discharge sides of the pump to prevent backflow of water.
2. Turn the lid's locking ring counter-clockwise until 'START' aligns with the ports. Carefully remove the lid. (You may use a tool for leverage.)

CAUTION

A misaligned basket will cause the lid to be improperly seated, allowing an air leak, which could result in pump damage.

1. Lift the basket out of the pump.
2. Dispose of the debris and thoroughly clean the basket, making sure all the holes are open. Using a garden hose, spray the basket from the outside to help clear the holes. Remove any remaining debris by hand.
3. Replace the basket in the pump by aligning the opening with the suction pipe. If aligned properly, the basket will drop easily into place. Do not force it into place.
4. Remove the lid seal and remove debris around the lid seal seat, as this can allow air to leak into the system. Clean the lid seal and place it on the lid.
5. Replace the lid with locking ring. Hand-tighten the lid to make an air-tight seal. Do not use any tools to tighten the lid: hand-tighten only.
6. Verify that all valves have been returned to the proper position for normal operation.
7. Open the pressure release valve on the filter, and make sure it is clean and ready for operation.
8. Turn on the power to the pump. Once all the air has been evacuated from the filter, close the pressure release valve.

5.2 Winterizing the Pump

CAUTION

The pump must be protected when freezing temperatures are expected. Allowing the pump to freeze will cause severe damage and void the warranty.

CAUTION

Do not use antifreeze solutions in the pool, spa, or hot tub systems! Antifreeze is highly toxic and may damage the circulation system. The only exception to this is Propylene Glycol. For more information, see your local pool/spa supply store or contact a qualified swimming pool service company.

1. Drain all water from the pump, system equipment, and piping.
2. Remove the two (2) drain plugs. Store the drain plugs in a safe location and reinstall them when the cold weather season is over. Do not lose the o-rings.
3. Keep the motor covered and dry. Do not cover the pump with plastic, because this will create condensation that will damage the pump.

NOTE Zodiac Pool Systems, Inc. recommends having a qualified service technician or electrician properly disconnect the electrical wiring at the switch or junction box. Once the power is removed, loosen the two (2) unions and store the pump indoors. For safety, and to prevent entry of contaminants, reinstall all conduit and terminal box covers.

1. When the system is reopened for operation, have a qualified technician or electrician make sure all piping, valves, wiring and equipment are in accordance with the manufacturer's recommendations. Pay close attention to the filter and electrical connections.

2. The pump must be primed prior to starting. Refer to Section 4.1, Start-up.
