5. Setup and Installation
Proper installation is crucial for the longevity and performance of your pump. Always consult local plumbing and electrical codes.
5.1. Site Selection
- Install the pump in a dry, well-ventilated location protected from direct sunlight and freezing temperatures.
- Mount the pump on a solid, level surface to prevent movement and vibration.
- Position the pump as close as possible to the water source to minimize suction lift.
5.2. Plumbing Connections
- The pump's suction inlet is 1-1/4 inch FNPT, and the discharge is 1 inch FNPT. Do not reduce the size of the suction plumbing.
- Use appropriate pipe thread sealant (PTFE tape or thread compound) on all threaded connections. Do not overtighten.
- Ensure all joints are airtight to prevent air leaks, which can affect pump operation.
- Install a pressure relief valve in the discharge line, rated to handle pump flow at 75 PSI, to prevent over-pressurization.
5.3. Electrical Connections & Voltage Change
The SLC-L pump is convertible between 115V and 230V. It is factory-wired for 230V. Verify your power supply and adjust the motor voltage if necessary. All electrical work must be performed by a qualified technician.
- Always disconnect the electrical power at the main breaker before touching the pump or performing any wiring.
- Locate the motor's wiring diagram on the motor label (refer to Figure 3.2).
- Remove the motor cover to access the voltage selection switch or plug.
- Adjust the switch or plug to match your power supply (115V or 230V). Operating a 115V wired motor on 230V will destroy the motor.
- Connect the power lines to the pressure switch terminals marked L1 and L2. Ensure proper grounding.

6. Operating Instructions
6.1. Priming the Pump
- Before initial startup or after the pump has run dry, it must be primed.
- Remove the priming plug on top of the pump casing.
- Fill the pump casing completely with water until it overflows.
- Replace the priming plug securely.
6.2. Starting the Pump
- Ensure all plumbing connections are secure and leak-free.
- Open a faucet in the system to allow air to escape.
- Restore electrical power to the pump. The pump should start and begin to build pressure.
- Once a steady stream of water flows from the open faucet, close the faucet. The pump will continue to run until the system pressure reaches the cut-out setting of the pressure switch.
7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
- Winterization: In areas subject to freezing, drain the pump and all exposed piping completely to prevent damage.
- Inspection: Periodically check all connections for leaks and tighten as necessary.
- Cleaning: Keep the pump motor's ventilation openings clear of debris to ensure proper cooling.
- Pressure Switch: Ensure the pressure switch is functioning correctly. Adjustments should only be made by qualified personnel.
8. Troubleshooting
Before attempting any repairs, always disconnect power to the pump.
8.1. Pump Runs but Delivers No Water
- Check Priming: Ensure the pump is fully primed.
- Suction Line Leaks: Inspect the suction line for air leaks. Tighten all connections.
- Foot Valve/Strainer: Check if the foot valve is submerged or if the strainer is clogged.
- Well Water Level: Verify that the well has sufficient water.
8.2. Low Water Pressure
- Clogged Impeller: Debris may be partially blocking the impeller.
- Air in System: Check for air leaks in the suction line.
- Pressure Tank: Inspect the pressure tank's air charge.
- Worn Components: Internal pump components may be worn.
8.3. Pump Does Not Start
- No Power: Check circuit breaker or fuse.
- Incorrect Voltage: Verify the motor is wired for the correct voltage (115V or 230V).
- Motor Overload: The motor's thermal overload protector may have tripped. Allow it to cool and reset.
- Pressure Switch: The pressure switch may be faulty or stuck.
