4. Installation Guide

Proper installation is crucial for the pump's performance and longevity. If you are unsure about any step, consult a qualified plumber or electrician.

4.1 Pre-Installation Checks:

• Location: Choose a dry, level, and well-ventilated location protected from freezing temperatures and direct sunlight. The pump should be easily accessible for maintenance.
• Power Supply: Ensure a dedicated 115V AC, 60Hz power supply with appropriate circuit protection is available.
• Piping: Use appropriate piping materials (e.g., copper, PEX, PVC) that can withstand the system's pressure and temperature.

4.2 Plumbing Connection:

1. Install isolation valves on both the inlet and outlet sides of the pump to allow for easy servicing without draining the entire system.
2. Connect the incoming water supply line to the 1" NPT suction port of the pump.
3. Connect the outgoing water line to the 1" NPT discharge port of the pump.
4. Use thread sealant (e.g., PTFE tape) on all threaded connections to prevent leaks.
5. Ensure all connections are tight but do not overtighten, which can damage fittings.
6. For municipal water boosting, install the pump after the main water meter and before any branches to fixtures.

4.3 Electrical Connection:

1. Ensure the power supply is OFF at the circuit breaker before making any electrical connections.
2. Plug the pump's power cord into a properly grounded 115V outlet.
3. Verify that the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for added safety, especially in damp locations.

5. Operating Instructions

The K2 Pumps WPS07505PCK is designed for automatic operation, activating when water demand is detected and shutting off when demand ceases.

5.1 Initial Start-up and Priming:

1. Before starting the pump, ensure all plumbing connections are secure and leak-free.
2. Open the isolation valve on the inlet side of the pump to allow water to flow into the pump housing.
3. Priming: The pump must be primed with water before its first use. Locate the priming port (usually a plug on the top of the pump housing) and remove it. Slowly fill the pump housing with water until it overflows. Replace the priming plug securely.
4. Open a faucet downstream from the pump to allow air to escape the system.
5. Turn on the power to the pump. The pump should start running.
6. Allow the pump to run until a steady stream of water flows from the open faucet, indicating that all air has been purged from the system. Close the faucet.

5.2 Automatic Operation:

• Once primed, the pump will automatically sense a drop in pressure (e.g., when a faucet is opened) and activate to maintain desired water pressure.
• When water demand stops, the pump will automatically shut off after a short delay.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your booster pump.

Routine Checks:

• Inspect for Leaks: Periodically check all plumbing connections for any signs of leaks. Tighten connections as needed.
• Check Pressure Gauge: Monitor the pressure gauge to ensure the pump is operating within expected pressure ranges.
• Clean Exterior: Keep the pump's exterior clean and free from dust and debris to ensure proper motor cooling.

Winterization (for areas with freezing temperatures):

• If the pump is installed in an area subject to freezing, it must be drained to prevent damage.
• Disconnect power to the pump.
• Close the inlet and outlet isolation valves.
• Remove the drain plug (if present) or disconnect a union on the suction side to allow water to drain completely from the pump and associated piping.
• Store the pump in a warm, dry place if possible, or ensure it is thoroughly drained and protected from freezing.
