Setup and Installation
Proper installation is crucial for the pump's performance and safety. If you are unsure about any steps, consult a qualified professional.
1. Site Selection
- Choose a location that is level, dry, and well-ventilated.
- Ensure the pump is easily accessible for maintenance and servicing.
- Position the pump as close to the pool as possible to minimize friction loss in plumbing.
- Protect the pump from direct weather exposure.
2. Plumbing Connections
The pump is compatible with 1.5-inch and 2.0-inch NPT internal thread interfaces. Use appropriate fittings and sealants to ensure watertight connections.
- Connect the suction line (from the pool skimmer/main drain) to the pump's inlet.
- Connect the discharge line (to the pool return jets) to the pump's outlet.
- Ensure all connections are tight to prevent air leaks, which can affect priming and pump efficiency.

The pump supports both 1.5-inch and 2.0-inch NPT connections.
3. Electrical Connection
- Ensure the power supply matches the pump's voltage requirements (110V-120V, 60Hz).
- Connect the pump to a dedicated, grounded electrical circuit protected by a Ground Fault Circuit Interrupter (GFCI).
- Utilize the grounding terminal on the pump to connect a grounding wire, as per local electrical codes, for additional safety.
- Do not modify the power cord or plug.
Operating Instructions
1. Priming the Pump
Before starting the pump for the first time, or after cleaning the strainer basket, it is essential to prime the pump:
- Ensure all valves in the suction and discharge lines are open.
- Remove the transparent lid of the strainer basket.
- Fill the strainer basket with water until it reaches the suction pipe level.
- Replace the lid, ensuring it is securely tightened to prevent air leaks.
- Turn on the pump. The pump should begin to draw water and expel air from the discharge line. If the pump does not prime within 5 minutes, turn it off, re-check all connections for air leaks, and repeat the priming process.
2. Dual Speed Operation
This pump offers two speed settings:
- High Speed: Provides maximum flow (110 GPM) and lift (54 ft) for initial cleaning, vacuuming, or when rapid water circulation is needed.
- Low Speed: Offers reduced flow (52 GPM) and lift (14 ft) for continuous, energy-efficient filtration and daily maintenance. This setting is ideal for maintaining water clarity with lower power consumption.
Refer to the pump's control panel or switch for selecting between high and low speeds.

The pump offers high and low speed settings for varied circulation needs.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
1. Cleaning the Strainer Basket
The strainer basket collects debris and should be checked and cleaned regularly, especially when you notice reduced water flow.
- Turn off the pump and disconnect power.
- Close any necessary valves to prevent water from flowing back from the pool.
- Unscrew the transparent lid of the strainer basket.
- Remove the basket and empty any collected debris.
- Rinse the basket thoroughly with water.
- Inspect the O-ring on the lid for cracks or wear; replace if necessary. Lubricate the O-ring with a silicone-based lubricant.
- Place the clean basket back into the pump housing.
- Securely replace the lid, ensuring a tight seal.
- Open valves and re-prime the pump as described in the Operating Instructions.

Regularly clean the strainer basket to remove debris.
2. Winterization
If you live in an area with freezing temperatures, proper winterization is essential to prevent damage to the pump.
- Turn off the pump and disconnect power.
- Drain all water from the pump by removing the drain plug.
- Disconnect plumbing lines.
- Store the pump in a dry, frost-free location.
Troubleshooting
This section addresses common issues you might encounter with your pool pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; tripped breaker/GFCI; motor overload. | Check power supply, reset breaker/GFCI. Allow motor to cool if overloaded. |
| Pump runs but does not prime or has low flow | Strainer basket clogged; air leak in suction line; low water level in pool; closed valves; impeller clogged. | Clean strainer basket. Check all plumbing connections for air leaks. Ensure adequate pool water level. Open all valves. Inspect impeller for debris (disconnect power first). Re-prime the pump. |
| Pump is excessively noisy | Air leak in suction; cavitation (lack of water); motor bearing wear; pump not securely mounted. | Check for air leaks and ensure pump is primed. Verify adequate water supply to the pump. Ensure pump is mounted on a stable surface. If motor bearings are worn, professional service may be required. |
| Water leaks from pump | Loose plumbing connections; worn O-rings/seals; cracked housing. | Tighten connections. Inspect and replace O-rings/seals. If housing is cracked, pump may need replacement. |
| Low speed setting not working | Internal wiring issue; faulty speed switch. | Verify the speed switch is correctly engaged. If the issue persists, contact VEVOR customer support or a qualified technician. |
