Safety Level Definitions:
Level | Meaning |
---|---|
DANGER | Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. |
WARNING | Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury. |
CAUTION | Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury, or property damage. |
IMPORTANT | [Alert] ❗ |
PROHIBITED | ❌ |
DANGER Precautions:
- 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. Ensure 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 Precautions:
- 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 any 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 Precautions:
- All electrical wiring must conform with applicable local codes, regulations, and the National Electric Code (NEC).
- It is strongly advised to protect the electrical components from direct sunlight, though this pump is designed for outdoor use.
- Place this pump in a well-drained area that will not flood when it rains.
- 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 voiding the warranty. Fill the strainer housing with water before starting the motor.

Electrical Connection Notes:
- Ensure the available electrical supply is suitable for the motor's voltage, phase, and cycle.
- Voltage from the power source must be within 90% to 110% of the motor nameplate rated voltage. Deviations may cause the motor to overheat, leading to overload tripping and reduced component life.
- Install, ground, bond, and wire the motor in accordance with local or NEC requirements.
- The motor must be permanently grounded 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 from current passing between bonded metal objects if they become grounded or shorted.

Troubleshooting
Priming:
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 before proceeding with starting the pump.
MOTOR WILL NOT START
- Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCI's, or blown fuses.
- Manually check rotation of the motor shaft for free movement and lack of obstruction.
- If a timer is used, ensure it is working properly. Bypass it if necessary.
MOTOR SHUTS OFF
- Undersized wiring; loose connections; etc.
- Low voltage at the 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
- Ensure the pump strainer housing is filled with water and the cover O-ring is clean and properly seated in its groove. The strainer cover must be locked firmly in position and lubricated (e.g., with "Jack's 327").
- Verify all suction and discharge valves are fully open and not blocked. Ensure the pool water level is adequate and the skimmer weir is not hung up or stuck.
- To check for vacuum development, block off the outlet and run the pump. You should achieve 5"-6" of vacuum at the strainer cover. You can also check by removing the skimmer basket and placing your hand over the bottom port while the skimmer is full and the pump is running. If no suction is felt, check for line blockage.
- A. If pump develops a vacuum: Check for a blocked suction line, dirty strainer basket, or an air leak in the suction piping.
- B. If the pump does not develop a vacuum and has sufficient "priming water":
- i. Re-check strainer housing cover and all threaded connections for suction leaks. Ensure all hose clamps are tight.
- ii. Check voltage to ensure the motor is rotating at full RPM.
- iii. Open the housing cover and check for clogging or obstruction in the suction path. Inspect the impeller for debris.
- iv. Remove and replace the 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 (indicated by a high gauge reading). Correction: 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, a leak at any joint, low water level in the pool, or unrestricted discharge return lines. Correct the suction condition or throttle return lines, if practical.
NOISY PUMP
- Vibration due to improper mounting. Consider using a rubber pad under metal mounting feet.
- Foreign matter in the pump housing (e.g., loose stones/debris hitting the impeller). Remove any such obstructions.
- Noisy motor bearings may be caused by normal wear, rust, overheating, or chemical concentration leading to seal damage. This can allow chlorinated water to seep into bearings, washing out grease and causing whining noises. All seal leaks should be addressed immediately.
- Equipment base vibrating.
