4. 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.
4.1 Pre-Installation Checks:
- Ensure the installation site is level, stable, and can support the weight of the pump.
- Verify that the electrical supply matches the pump's requirements (110V/60Hz).
- Confirm all necessary plumbing components and tools are available.
4.2 Plumbing Connections:
- The pump comes with standard 1.5-inch and 2-inch PVC union adapters (V40/N50) to fit various PVC hoses and pipes, meeting U.S. plumbing standards.
- Identify the inlet (suction) and outlet (discharge) ports on the pump.
- Select the appropriate adapters for your plumbing size.
- Apply Teflon tape to the male threads of the pump ports and the female threads of the slip unions to ensure a secure, leak-free seal.
- Connect the adapters to your pool's plumbing system. Ensure all connections are tight but do not overtighten.
4.3 Initial Priming:
IMPORTANT: Before starting the pump for the first time, or after the pump has been drained, it must be primed with water to prevent damage.
- Ensure all valves in the suction line are open.
- Remove the transparent lid of the strainer basket.
- Fill the strainer basket housing completely with water.
- Replace the lid, ensuring it is securely tightened to prevent air leaks.
- Proceed to operating instructions.

5. Operating Instructions
Once installed and primed, your Leomru pool pump is ready for operation.
- Power On: Plug the pump into a grounded 110V/60Hz electrical outlet. The pump will begin operating.
- Monitor Flow: Observe the water flow from your pool's return jets to ensure proper circulation.
- Check Strainer Basket: Periodically check the transparent lid of the strainer basket for accumulated debris. A full basket can restrict flow and reduce pump efficiency.
- Run Time: The optimal run time for your pump depends on pool size, usage, and environmental factors. Consult your pool professional for recommended daily run times.
- Power Off: To stop the pump, simply unplug it from the electrical outlet.

7. Troubleshooting
This section addresses common issues you might encounter with your pool pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start or hums but doesn't run. | No power, incorrect voltage, motor overload, seized impeller. | Check power connection and circuit breaker. Ensure the pump is receiving 110V. Allow motor to cool if thermal overload tripped. Consult a professional if impeller is seized. |
| Low water flow or no flow. | Strainer basket clogged, air leak in suction line, pump not primed, closed valves, low water level in pool. | Clean strainer basket. Check all suction line connections for air leaks. Re-prime the pump. Ensure all valves are open. Check pool water level. |
| Pump is noisy. | Air leak in suction line, cavitation (lack of water), motor bearing wear, debris in impeller. | Check for air leaks. Ensure pump is fully primed and receiving adequate water. If noise persists, professional inspection may be needed. Clean impeller if accessible. |
| Water leaking from pump. | Loose connections, damaged O-rings or seals, cracked housing. | Tighten all plumbing connections. Inspect and replace damaged O-rings or seals. If housing is cracked, pump may need replacement. |
