Safety Instructions

WARNING – To reduce the risk of injury, do not permit children to use or climb on this product. Closely supervise children at all times. Components such as the filtration system, pumps, and heaters must be positioned to prevent children from using them as a means of access to the pool.

CAUTION – This pump is intended for use on permanently installed swimming pools and may also be used with hot tubs and spas if needed. 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.

Though this product can be for outdoors, it is strongly advised to protect the electrical components from the weather.
Select a well-drained area, one that will not flood when it rains. It requires free circulation of air for cooling. Do not install in a damp or non-ventilated location. If installed within an outer enclosure or beneath the skirt of a hot tub or spa, adequate ventilation and free circulation of air must be provided to prevent overheating of the motor.

WARNING – Pool and spa components have a finite life. All components should be inspected frequently and replaced at least every ten years, or if found to be damaged, broken, cracked, missing, or not securely attached..

WARNING – Risk of Electric Shock.

Hazardous voltage can shock, burn, or cause death. To reduce the risk of electric shock, do NOT use an extension cord to connect the unit to the electric supply. Provide a properly located outlet. It is required that licensed electricians do all electrical wiring. All electrical wiring MUST be in conformance with applicable local and national codes and regulations. Before working on the pump or motor, disconnect the motor wiring.

WARNING – To reduce the risk of electric shock, replace the damaged cord immediately. Do NOT bury the cord. Locate cords to prevent abuse from lawn mowers, hedge trimmers, and other equipment.

WARNING – Connect only to a grounding type receptacle protected by a Ground Fault Circuit Interrupter (GFCI). Contact a licensed electrician if you cannot verify that the receptacle is protected by a GFCI.

WARNING

Failure to bond the pump to the pool structure will increase risk for electrocution and could result in injury or death. To reduce the risk of electric shock, see the installation instructions and consult a professional electrician on how to bond the pump. Also, contact a licensed electrician for information on local electrical codes for bonding requirements. Use a solid copper conductor, size 8 or larger. Run a continuous wire from the external bonding lug to the reinforcing rod or mesh. Use No. 12 AWG (3.21 mm2) earthing wire connected to the earthing terminal provided on the back cover of each pump to connect any metal parts of swimming pool, spa, or hot tub, and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5m) of inside walls of swimming pool, spa, or hot tub.

IMPORTANT – Reference NEC codes for all wiring standards, including, but not limited to, grounding, bonding, and other general wiring procedures. NOTE – The National Electrical Code (NEC) permits use of a cord with a maximum 3 ft. (1 m) length. If your pump is equipped with a cord complying with the NEC, the preceding four (4) hazards apply.

WARNING – Suction Entrapment Hazard.

Suction in suction outlets and/or suction outlet covers, which are damaged, broken, cracked, missing, or unsecured, red cause severe injury and/or death due to the following entrapment hazards:

Hair Entrapment- Hair can become entangled in the suction outlet cover.
Limb Entrapment- A limb inserted into an opening of a suction outlet sump or suction outlet cover that is damaged, broken, cracked, missing, or not securely attached can result in a mechanical bind or swelling of the limb.
Body Suction Entrapment- A pressure applied to a large portion of the body or limbs can result in an entrapment.
Evisceration/ Disembowelment- A negative pressure applied directly to the intestines through an unprotected suction outlet sump or suction outlet cover, which is damaged, broken, cracked, missing, or unsecured, can result in evisceration/disembowelment.
Mechanical Entrapment- There is potential for jewelry, swimsuits, hair decorations, fingers, toes, or knuckles to be caught in an opening of a suction outlet cove, resulting in mechanical entrapment.

WARNING – To Reduce the Risk of Entrapment Hazards

When outlets are small enough to be blocked by a person, a minimum of two functioning suction outlets per pump must be installed. Suction outlets in the same place (i.,e. floor or wall) must be installed a minimum of three feet (3’) [0.91 meter] apart, as measured from near point to near point.
Dual suction fittings shall be placed in such locations and distances to avoid “dual blockage” by a user.
Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas.
The maximum system flow rate shall not exceed the values shown in the “Pipe Sizing Chart” found on page 5 of this manual.
– Never use the pool or spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached.
Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately.
In addition to two or more suction outlets per pump installed in accordance with the latest IAF (formerly NSPI) standards and CPSC guidelines, follow all national, state, and local codes applicable.
Installation of a vacuum release or vent system, which relieves entrapping suction, is recommended.

WARNING – Hazardous Pressure.

Pool and spa water circulation systems operate under hazardous pressure during start-up, normal operation, and after pump shut-off. Keep clear of the circulation system equipment during pump start-up. Failure to follow safety and operation instructions could result in violent separation of the pump housing and cover due to pressure in the system, which could cause property damage, severe personal injury, or death. Before servicing the pool and spa water circulation system, all system and pump controls must be in the off position, and the filter manual air relief valve must be in the open position.

Before starting the system pump, all system valves must be set in a position to allow system water to return to the pool. Do not change the filter control valve position while the system pump is running. Before starting the system pump, fully open the filter manual air relief valve. Do not close the filter manual air relief valve until a steady stream of water (not air or air and water) is discharged. All suction and discharge valves MUST be OPEN when starting the circulation system. Failure to do so could result in severe personal injury and/or property damage.

WARNING – Separation Hazard.

Failure to follow safety and operation instructions could result in violent separation of pump components. The strainer cover must be properly secured to the pump housing with the strainer cover lock ringing. Before servicing the pool and spa circulation system, all system and pump controls must be in the off position, and the filter manual air relief valve must be in the open position.

Do not operate the pool and spa circulation system if a system component is not assembled properly, damaged, or missing. Do not operate the pool and spa circulation system unless the filter air relief valve body is in the locked position in the filter upper body. All suction and discharge valves MUST be OPEN when starting the circulation system. Failure to do these could result in severe personal injury and/or property damage.

WARNING – Never operate or test the circulation system at more than 40 PSI.

WARNING – Fire and burn hazard.

Motors operate at high temperatures, and if they are not properly isolated from any flammable structures or foreign debris, they can cause fires, which may cause severe personal injury or death. It is also necessary to allow the motor to cool for at least 20 minutes before maintenance to minimize the risk of burns.

WARNING – Failure to install according to the defined instructions may result in severe personal injury or death.

Installation Instructions

WARNING – This product should be installed and serviced only by a qualified professional.

Pump Location

Locate the pump as close to the pool as possible and run suction lines as directly as possible to reduce friction loss. Suction lines should have a continuous slope upward from the lowest point in the line. Joints must be tight (but not over-tightened). Suction line diameter must equal or be larger than the discharge line diameter.

Though this product can be used outdoors, it is strongly advised to protect the electrical components from the weather. Select a well-drained area, one that will not flood when it rains. Do NOT install the pump in a damp or non-ventilated location. Keep the motor clean. Pump motors require free circulation of air for cooling.

Pump Mounting

Install the pump on a firm, level base or pad to meet all local and national codes. Fasten the pump to the base or pad with screws or bolts to further reduce vibration and stress on pipe or hose joints. The base MUST be solid, level, rigid, and vibration-free.

The pump mount must

Allow the pump inlet height to be as close to the water level as possible.
Allow use of short, direct suction pipe (to reduce friction losses).
Allow for gate valves in suction and discharge piping.
Be protected from excess moisture and flooding.
Allow adequate access for servicing the pump and piping.

Pipe Sizing Chart

NOTE – It is recommended that a minimum length of piping, equivalent to 10 pipe diameters, be used between the pump suction inlet and any plumbing fittings.

WARNING – Hazardous Pressure.

Pumps, filters, and other equipment/components of a swimming pool filtration system operate under pressure. Incorrectly installed and/or improperly tested filtration equipment and/or components may fail, resulting in injury and/or property damage.

Plumbing

Use Teflon tape to seal threaded connections on molded plastic components. All plastic fittings must be new or thoroughly cleaned before use. NOTE – Do NOT use Plumber’s Pipe Dope as it may cause cracking of the plastic components. When applying Teflon tape to plastic threads, wrap the entire threaded portion of the male fitting with one to two layers of tape. Wind the tape clockwise as you face the open end of the fitting, beginning at the end of the fitting. The pump suction and outlet ports have molded-in thread stops.

Do NOT attempt to force the hose connector fitting past this stop. It is only necessary to tighten fittings enough to prevent leakage. Tighten the fitting by hand and then use a tool to engage the fitting an additional 1 ½ turns. Use carefully when using Teflon tape as friction is reduced considerably; Do not over-tighten the fitting, or you may cause damage. If leaks occur, remove the connector, clean off old Teflon tape, re-wrap with one to two additional layers of Teflon tape, and re-install the connector.

Fittings

Fittings restrict flow. For better efficiency, use the fewest possible fittings (but at least two suction outlets). Avoid fittings that could cause an air trap. Pool and spa fittings MUST conform to the International Association of Plumbing and Mechanical Officials (IAPMO) standards. Use a non-entrapping suction fitting in a pool (multiple drains) or a double suction (skimmer and main drain).

Electrical

WARNING – Ground and bond the motor before connecting to the electrical power supply. Failure to ground and bond the pump motor can cause a serious or fatal electrical shock hazard.

WARNING – Do NOT ground to a gas supply line.

WARNING – To avoid dangerous or fatal electrical shock, turn OFF the power to the motor before working on electrical connections.

WARNING – Ground Fault Circuit Interrupter (GFCI) tripping indicates an electrical problem. If the GFCI trips and won’t reset, consult an electrician to inspect and repair the electrical system.

WARNING – Fire Hazard.

Match the supply voltage to the motor nameplate voltage.

Ensure that the electrical supply available agrees with the motor’s voltage, phase, and cycle, and that the wire size is adequate for the HP (KW) rating and distance from the power source. NOTE – All electrical wiring MUST be performed by a licensed electrician, and MUST conform to local codes and NEC regulations. Use copper conductors only.

Voltage

Voltage at the motor MUST NOT be more than 10% above or below the motor nameplate rated voltage, or the motor may overheat, causing overload tripping and reducing component life. If the voltage is less than 90% or more than 110% of the rated voltage when the motor is running at full load, consult the Power Company.

Grounding And Bonding

Install, ground, bond, and wire the motor in accordance with local or national electrical code requirements. Permanently ground motor. There is an earthing wire on the back cover of each pump. Bond the motor to the pool structure. Bonding will connect any metal parts within and around the pool with the earthing wire. Bonding reduces the risk of a current passing between bonded metal objects, which could potentially cause electrical shock if grounded or shorted. Reference NEC codes for all wiring standards, including, but not limited to, grounding, bonding, and general wiring procedures.

Use a solid copper conductor, size 12 or larger. Run a wire from the external bonding lug to the reinforcing rod or mesh. Connect the No. 12 AWG (3.21 mm2) earthing wire to the earthing terminal provided on back cover of each pump and to any metal parts of swimming pool, spa, or hot tub, and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of swimming pool, spa, or hot tub.

Wiring

WARNING – All wiring must be done by a licensed electrician.

Pump MUST be permanently connected to the circuit. If other lights or appliances are also on the same circuit, be sure to add their amp loads before calculating wire and circuit breaker sizes. Use the load circuit breaker as the Master On-Off switch.

Install a Ground Fault Circuit Interrupter (GFCI) in the circuit; it will sense a short-circuit to ground and disconnect power before it becomes dangerous to pool users. For the size of GFCI required and test procedures for GFCI, see the manufacturer’s instructions. In case of a power outage, check the GFCI for tripping, which will prevent normal pump operation. Reset if necessary.

NOTE – If you do not use conduit when wiring a motor, be sure to seal the wire opening on the end of the motor to prevent dirt, bugs, etc., from entering.

Start-Up & Operation

Before Start-Up

Notice: If it is necessary to perform a pressure test, before initial use, to ensure the pump is functioning properly, then the following criteria should be maintained for this test:

Have a professional perform this test.
Ensure all pump and system components are sealed properly to prevent leaks.
Remove any trapped air in the system by fully opening the filter’s manual air relief valve until a steady stream of water is discharged.
Allow no more than 40 psi (276 kPa) at a water temperature no higher than 100°F(38°CC).
Run a pressure test for no longer than 24 hours. Immediately inspect all parts to verify they are intact and functioning properly.

Fill the strainer housing with water to the suction pipe level. NEVER OPERATE THE PUMP WITHOUT WATER. Water acts as a coolant and lubricant for the mechanical shaft seal.

WARNING – If the pump is being pressure tested (40 PSI MAXIMUM), be sure pressure has been released, using the filter manual air relief valve, before removing the strainer cover.

CAUTION – NEVER run the pump dry. Running the pump dry may damage seals, causing leakage, flooding, and voiding the warranty. Fill the strainer housing with water before starting the motor.

ATTENTION – Do NOT add chemicals to the pool/spa system directly in front of the pump suction. Adding undiluted chemicals may damage the pump and void the warranty.

ATTENTION – Before removing strainer cover:

STOP PUMP before proceeding.
CLOSE VALVES in suction and outlet pipes.
RELEASE ALL PRESSURE from the pump and piping system using the filter manual air relief valve. See the filter owner’s manual for more details.

Priming Pump

CAUTION – All suction and discharge valves MUST be OPEN, as well as the filter air relief valve (if available the filter, when starting the circulating pump system. Failure to do so could result in severe personal injury.

Release all pressure from the filter, pump, and piping system. See the filter owner’s manual.
If the water source is higher than the pump, the pump will prime itself when the suction and outlet valves are opened. If the water source is lower than the pump, unscrew and remove the strainer cover; fill the strainer housing with water.
Clean and lubricate the strainer cover O-ring with “Jack’s 327” each time it is removed. Inspect the O-ring and reinstall it on the trainer cover.
Replace the strainer cover on the strainer housing; turn clockwise to tighten the cover.

NOTE – Tighten strainer cover by hand only (not wrenches).

Turn on the power and wait for the pump to prime, which may take up to five (5) minutes. Priming time will depend on the vertical length of the suction lift and the horizontal length of the suction pipe. If the pump does NOT prime within five minutes, stop the motor and determine the cause. Be sure all suction and discharge valves are open when the pump is running. See Troubleshooting Guide.

ATTENTION – Wait five (5) seconds before restarting the ump. Failure to do so may cause reverse rotation of the motor and consequent serious pump damage.

Close the filter manual air relief valve after the pump is primed.

Maintenance

Clean the strainer basket regularly. Do NOT strike the basket to clean. Inspect the strainer cover gasket regularly and replace as necessary.
Pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.
Keep the motor clean. Ensure air vents are free from obstruction to avoid damage. Do NOT use water to hose off the motor.
Occasionally, shaft seals must be replaced due to wear or damage. Replace with ga enuine seal assembly kit.

See “Shaft Seal Change Instructions” in this manual.

Storage/Winterization

WARNING – Separation Hazard.

Do not purge the system with compressed air. Purging the system with compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only a low-pressure (below 5 PSI), high-volume blower when air purging the pump, filter, or piping.

ATTENTION – Allowing the pump to freeze will void the warranty.

ATTENTION – Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol is nontoxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic components in the system.

Drain all water from the pump and piping when expecting freezing temperatures or when storing the pump for a long time (see instructions below).

Keep the motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap the pump with plastic film or bags.

Storing Pump For Winterization

WARNING – To avoid a dangerous or fatal electrical shock hazard, turn OFF the power to the motor before draining the pump.

Failure to disconnect power may result in serious personal injury or death.

Drain the water level below all inlets to the pool.
Remove drain plugs from the bottom of the strainer body, and remove the strainer cover from the strainer housing.
Disconnect the pump from the mounting pad, wiring system (after power has been turned OFF), and piping system.
Once the pump is removed from the water, reinstall the strainer cover and drain plugs. Store the pump in a dry area.

Shaft Seal Change Instructions

IMPORTANT SAFETY INSTRUCTIONS

PLEASE READ AND FOLLOW ALL INSTRUCTIONS

When servicing electrical equipment, basic safety precautions should always be observed, including the following. Failure to follow instructions may result in injury.

WARNING – To reduce the risk of injury, do not permit children to use this product.
Disconnect all electrical power service to the pump before beginning the shaft seal replacement.
Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Dealer or service center if you have any questions.
The National Electrical Code requires either a three (3) foot maximum twist-lock cord set with a GFCI-protected receptacle or a hard-wire (conduit) connection for swimming pool pump installation. Do not use extension cords.
Exercise extreme care in handling both the rotating and the stationary sections of the two-part replacement seal. Foreign matter or improper handling will easily scratch the graphite and ceramic sealing surfaces.

Troubleshooting

Motor Will NOT Start – Check For

Make sure the terminal board connections agree with the wiring diagram inside the terminal box. Be sure the motor is wired for the available field supply voltage (see pump operating label).

Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCIs, or blown fuses.
Solution: Check all connections, circuit breakers, and fuses. Reset tripped breakers or replace blown fuses.
Manually check the rotation of the motor shaft for free movement and lack of obstruction.
Solution: Refer to Steps 4 & 5 of “Shaft Seal Change Instructions” in this manual.
If you have a timer, be certain it is working properly. Bypass it if necessary.

Motor Shuts OFF – Check For

Low voltage at the motor or power drop (frequently caused by undersized wiring or extension cord use).
Solution: Contact a qualified professional to check that the wiring gauge is heavy enough.
NOTE – Your pump motor is equipped with an “automatic thermal overload protector.” The motor will automatically shut off if the power supply drops before heat damage can build up, causing windings to burn out. The “thermal overload protector” will allow the motor to automatically restart once the motor has cooled. It will continue to turn on/off until the problem is corrected. Be sure to correct the cause of overheating.

Motor Hums, But Does NOT Start – Check For

Impeller jammed with debris.
Solution: Have a qualified repair professional open the pump and remove the debris.

Pump Won’t Prime, Check For

Empty pump/strainer housing.
Solution: Make sure the pump/strainer housing is filled with water, and the cover o-ring is clean. Ensure the o-ring is properly seated in the cover o-ring groove. Ensure the o-ring is lubricated with “Jack’s 327” and that the strainer cover is locked firmly in position. Lubricant will help to create a tighter seal.
Loose connections on the suction side.
Solution: Tighten pipe/union connections.
NOTE – Any self-priming pump will not prime if there are suction air leaks. Leaks will result in bubbles emanating from return fittings on the pool wall.
Leaking O-ring or packing glands on valves.
Solution: Tighten, repair, or replace valves.
Strainer basket or skimmer basket loaded with debris.
Solution: Remove the strainer housing cover or skimmer cover, clean the basket, and refill the strainer housing with water. Tighten the cover.
Suction side clogged.
Solution: Contact a qualified repair professional.
Block off to determine if the pump will develop a vacuum. You should have 5”-6” of vacuum at the strainer cover (Only your pool dealer can confirm this with a vacuum gauge). You may be able to check by removing the skimmer basket and holding your hand over the bottom port with the skimmer full and the pump running. If no suction is felt, check for line blockage.
1. If the pump develops a vacuum, check for a blocked suction line or dirty strainer basket. An air leak in the suction piping may be the cause.
2. If the pump does not develop a vacuum and the pump has sufficient “priming water”:
  1. Re-check the strainer housing cover and all threaded connections for suction leaks. Check if all system hose clamps are tight.
  2. Check the voltage to ensure that the motor is rotating at full RPMs.
  3. Open the housing cover and check for clogging or obstruction in the suction. Check the impeller for debris.
  4. Remove and replace the shaft seal only if it is leaking.

Low Flow – Generally, Check For

Clogged or restricted strainer or suction line.
Solution: Contact a qualified repair professional.
Undersized pool piping.
Solution: Correct piping size.
Plugged or restricted discharge line of filter, valve partially closed (high gauge reading).
Solution: Sand filters – backwash as per manufacturer’s instructions; D.E. filters – backwash as per manufacturer’s instructions; Cartridge filters – clean or replace cartridge.
Air leak in suction (bubbles issuing from return fittings).
Solution: Re-tighten suction and discharge connections using Teflon tape. Inspect other plumbing connections and tighten as required.
Plugged, restricted, or damaged impeller.
Solution: Replace, including a new seal assembly.

Noisy Pump – Check For

Air leak in suction piping, cavitations caused by restricted or undersized suction line, or leak at any joint, low water level in pool, and unrestricted discharge return lines.
Solution: Correct suction condition or throttle return lines, if practical. Holding a hand over the return fitting will sometimes prove this point, or putting in a smaller eyeball fitting.
Vibration due to improper mounting, etc.
Solution: Mount the pump on a level surface and secure the pump to the equipment pad.
Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause.
Solution: Clean the pump housing.
Motor bearings are noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage, which will allow chlorinated water to seep into the bearing, wiping out the grease, causing the bearing to whine.
Solution: All seal leaks should be replaced at once.
