2. Setup and Installation

Proper installation is crucial for the optimal performance and longevity of your WAYNE SWS50 pump. Always consult local codes and a qualified professional if you are unsure about any steps.

2.1 Site Preparation

• Ensure the pump is installed on a solid, level surface to minimize vibration.
• Protect the pump from freezing temperatures and direct weather exposure.
• Verify that the well depth does not exceed 25 feet for optimal shallow well pump operation.

2.2 Plumbing Connections

• The pump features a 1-1/4 inch NPT suction inlet and a 3/4 inch NPT discharge outlet.
• Use appropriate adapters if your existing plumbing differs (e.g., a 7/8 inch NPT to 1 inch NPT adapter for the top output hole if replacing an older pump).
• Install a foot valve or check valve at the end of the suction line in the well to maintain prime.
• Ensure all connections are airtight to prevent air leaks, which can cause priming issues.

2.3 Electrical Connections

• The pump is dual voltage (120V/240V) and factory-set for 240V. Verify your power supply matches the pump's setting.
• If changing voltage, follow the instructions on the motor label for the quick-change voltage selection switch.
• Connect the pump to a dedicated, properly grounded electrical circuit with appropriate overcurrent protection.
• The pressure switch is pre-set at 30 PSI ON and 50 PSI OFF. Ensure proper wiring to the pressure switch.

2.4 Priming the Pump

The pump self-primes after its housing is filled with water. Follow these steps:

1. Remove the priming plug located on the top of the pump housing.
2. Fill the pump volute completely with clean water through the dedicated priming port until water overflows.
3. Replace the priming plug securely.
4. Open a faucet or valve on the discharge side of the pump to allow air to escape.
5. Turn on the pump. It may take several minutes for the pump to establish prime, especially with long suction lines. Continue to refill the water chamber with cold water every 3-5 minutes if priming takes an extended period.
6. Once water flows steadily from the open faucet, close the faucet. The pump should build pressure and shut off automatically at 50 PSI.

3. Operating Instructions

Once properly installed and primed, the WAYNE SWS50 pump operates automatically based on demand and the pressure switch settings.

• The pump will turn on when the system pressure drops to 30 PSI and turn off when it reaches 50 PSI.
• Ensure there is always water in the well to prevent the pump from running dry, which can cause damage.
• Monitor the pressure gauge (if installed) to confirm proper operation and pressure cycling.

4. Maintenance

Regular maintenance helps ensure the long-term reliability and efficiency of your pump.

4.1 Seasonal Maintenance

• Winterization: In areas subject to freezing temperatures, drain the pump completely to prevent damage from ice expansion. Remove the drain plug and priming plug to allow all water to escape. Store the pump in a warm, dry place if possible.
• Spring Startup: Before restarting the pump after winterization, inspect all connections for leaks and ensure the pump is properly primed as described in Section 2.4.

4.2 General Checks

• Periodically check all plumbing connections for leaks.
• Ensure the pump's mounting is secure and free from excessive vibration.
• Listen for unusual noises during operation, which could indicate a problem.
