Safety Information

Always observe the following safety precautions to prevent injury or damage to the pump:

• Ensure the power supply is disconnected before performing any installation, maintenance, or troubleshooting.
• Do not run the pump dry for extended periods, as this can damage the impeller.
• Verify all connections are secure and leak-free before operation.
• Wear appropriate personal protective equipment (PPE) during installation and maintenance.

Setup and Installation

Proper installation is crucial for the pump's performance and longevity.

Unpacking

Carefully remove the pump from its packaging. Inspect for any signs of shipping damage. The package should contain the Johnson Pump 10-35038-5 F35B Pedestal-Style Impeller Pump.

Mounting

1. Select a mounting location that is stable, easily accessible for maintenance, and protected from excessive heat or direct sunlight.
2. Ensure the pump is mounted securely to prevent vibration during operation. Use appropriate fasteners for the mounting surface.
3. Allow sufficient space around the pump for air circulation and hose connections.

Plumbing Connections

1. Connect the inlet hose to the suction port and the outlet hose to the discharge port. Ensure hoses are of the correct diameter and are securely clamped.
2. Minimize bends and restrictions in the plumbing to optimize flow.
3. For raw water applications, ensure a suitable strainer is installed on the inlet side to prevent debris from entering the pump.

Operating Instructions

Follow these steps for safe and effective operation of your impeller pump.

1. Priming: Due to its excellent self-priming capability, the pump will typically prime itself if there is liquid available at the inlet. For initial startup or after extended dry periods, ensure the inlet hose is submerged in the liquid to be pumped.
2. Starting the Pump: Once all connections are secure and the system is ready, activate the power supply to the pump.
3. Monitoring: Observe the pump during operation for any unusual noises, vibrations, or leaks. Ensure a stable pressure delivery.
4. Stopping the Pump: Deactivate the power supply to the pump when pumping is complete or if an issue is detected.

Important: Avoid running the pump dry for more than a few seconds, as this can cause premature wear and damage to the impeller and seal.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your Johnson Pump.

Routine Checks

• Inspect Hoses and Connections: Periodically check all hoses for cracks, kinks, or wear. Ensure all clamps and connections are tight to prevent leaks.
• Check for Leaks: Visually inspect the pump and plumbing for any signs of leaks during and after operation.
• Clean Strainer: If an inlet strainer is used, regularly clean it to prevent blockages and maintain flow.

Impeller Replacement

The impeller is a wear part and should be inspected and replaced periodically, depending on usage and fluid pumped. Signs of a worn impeller include reduced flow, loss of prime, or increased noise.

1. Disconnect power to the pump.
2. Remove the cover plate screws and carefully remove the cover plate.
3. Extract the old impeller using an impeller puller or by carefully prying it out.
4. Clean the pump housing interior.
5. Lubricate the new impeller with a small amount of water or glycerin and insert it into the housing, ensuring the vanes are bent in the correct direction of rotation.
6. Replace the cover plate gasket (if applicable) and secure the cover plate with screws.

Winterization (if applicable)

If the pump is used in an environment where freezing temperatures occur, it must be properly winterized to prevent damage. Drain all water from the pump and plumbing system. Consider flushing with non-toxic antifreeze if recommended for your specific application.
