ATTENTION INSTALLER: This manual contains important information about the installation, operation, and safe use of this pump. Failure to read and follow all instructions could result in serious injury.

WARNING: This product should be installed and serviced by a qualified pool professional.

Installation Guidelines:

• This pump is compatible with above-ground pools and spas.
• Locate the pump as close to the pool and water level as possible.
• Avoid using too many elbow pipes in the plumbing to prevent suction reduction.
• It is highly recommended that the pump be placed in cool, dry places and avoid direct sunlight.
• Install the pump on a firm, level base or pad that meets 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.
• Use Teflon tape on the threads before screwing fittings to the pump inlet and outlet ports to avoid leakage. Do not over-tighten the fittings.

Safety Precautions

Read these safety precautions before operation. The information provided is crucial for the proper use of this product and to prevent harm or danger to users and others.

DANGER

• ⚠️ Stay off the main drain and away from all suction outlets.
• ⚠️ Strainer cover must be properly secured to prevent violent separation due to pressure in the circulation system.
• ⚠️ Before servicing, turn all circulation system and pump controls off, make sure the filter manual air relief valve is in the open position, and all pressure is relieved.
• ⚠️ It is highly recommended that this product be installed and serviced by a qualified pool professional.

WARNING

• ⚠️ Remove pressure test plugs and/or plugs used in winterization of the pool/spa from the suction outlets. Failure to do so will result in an increased potential for suction entrapment.
• ⚠️ Do not permit children to play with this product.
• ⚠️ Before starting the system pump, all system valves must be set to allow system water to return to the pool.
• ⚠️ Do not operate the pool and spa circulation system if a system component is not assembled properly, damaged, or missing.
• ⚠️ Before working on any electrical equipment, turn off the power supply to the equipment.
• ⚠️ Connect only to a branch circuit protected by a ground-fault circuit interrupter (GFCI).

CAUTION

• ℹ️ All electrical wiring must be in conformance with applicable local codes, regulations, and the National Electric Code (NEC).
• ℹ️ It is strongly advised to protect the electrical components from direct sunlight, though this pump is designed for outdoor use.
• ℹ️ Place this pump in a well-drained area, one that will not flood when it rains.
• ℹ️ 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.
• ? Do not install this pump in a damp or non-ventilated location. It requires free circulation of air for cooling.
• ? Do not run the pump dry. Water acts as a coolant and lubricant for the mechanical shaft seal. Running the pump dry may damage seals, causing leakage, flooding, and void warranty. Fill strainer housing with water before starting the motor.

Specifications and Diagrams

Dimensions:

The X-axis represents Flow Rate in liters/min (0-500) and m³/h (0-30). Two curves are shown, labeled "1.5THP" and "2.0THP", illustrating the head pressure at different flow rates for each model.]

Pump Discharge Port Adjustment

The pump discharge port can be turned to a horizontal orientation. Follow these steps:

• Remove pump lid and Strainer.
• Remove clip-bayonet (part # 4 in the parts list).
• Remove the pump strainer body from the pump housing.
• Unscrew the 8 bolts.
• Turn the discharge port to be horizontal.
• Screw back the 8 bolts.
• Re-install the pump strainer body.
• Buckle up the clip-bayonet.
• Put Strainer back into the pump strainer body.
• Fasten pump lid.

Electrical Requirements and Connections

Ensure the electrical supply available is suitable for the motor's voltage, phase, and cycle.

• Voltage from the power must be in the range from 90% to 110% of the motor nameplate rated voltage. Otherwise, the motor may overheat and result in overload tripping and reduced component life.
• Install, ground, bond, and wire the motor in accordance with local or NEC requirements.
• The motor should be grounded permanently by connecting the ground terminal to the electrical service ground.
• Bond the motor to the pool structure. Bonding connects all metal parts within and around the pool with a continuous wire, reducing the risk of electrical shock if grounded or shorted.

Priming the Pump

Proper priming is essential before starting the pump.

• Fill the strainer housing with water up to the suction pipe level.
• If water leakage occurs anywhere on the pump or filter, DO NOT start the pump.
• If no leakage occurs, stand at least 10 feet from the pump and/or filter and proceed with starting the pump.

Troubleshooting

MOTOR WILL NOT START

• Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCIs, or blown fuses.
• Manually check rotation of motor shaft for free movement and lack of obstruction.
• If you have a timer, make sure it is working properly. Bypass it if necessary.

MOTOR SHUTS OFF

• Undersized wiring; loose connections; etc.
• Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).

MOTOR HUMS BUT DOES NOT START

• Mechanical binding and electrical overload.
• Centrifugal switch stuck in the OPEN position.
• Binding of the motor shaft.

PUMP WON'T PRIME

• Make sure pump strainer housing is filled with water and the cover O-ring is clean; also, be sure it is properly seated in the cover O-ring groove. Make sure the strainer cover is locked firmly in position and lubricated.
• Make sure all suction and discharge valves are fully open and not blocked, that the pool water level is at a proper level, and that the skimmer weir is not hung up or stuck on the skimmer wall.
• Block off to determine if the pump will develop a vacuum. You should have 5"-6" of vacuum at the strainer cover. You may be able to check by removing the skimmer basket and holding your hand over the bottom port with the skimmer full and pump running. If no suction is felt, check for line blockage.
• a. If pump develops a vacuum, check for a blocked suction line or dirty strainer basket, and an air leak in the suction piping may be the cause.
• b. If the pump does not develop a vacuum and the pump has sufficient "priming water": i. Re-check strainer housing cover and all threaded connections for suction leaks. Check if all hose clamps are tight. ii. Check voltage to ensure that the motor is rotating at full RPM. iii. Open housing cover and check clogging or obstruction in suction. Check impeller for debris. iv. Remove and replace shaft seal only if it is leaking.

LOW FLOW

• Clogged or restricted strainer or suction line; undersized pool piping.
• Plugged or restricted discharge line or filter, valve partially closed (high gauge reading).
• How to correct: Backwash strainer as per manufacturer's instructions.
• Air leak in suction piping causing rumbling in the pump.
• Cavitation due to restricted or undersized suction line or leak at any joint, low water level in the pool, and unrestricted discharge return lines. Correct suction condition or throttle return lines, if practical.

NOISY PUMP

• Vibration due to improper mounting, etc. Put a rubber pad under metal mounting feet.
• Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause; remove any above.
• Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage which will allow chlorinated water to seep into bearings, wiping out the grease and causing bearing to whine. All seal leaks should be replaced at once.
• Equipment base vibrating.
