5. Setup
Follow these steps for proper installation of your Tsurumi 12PN pump:
- Placement: Position the pump on a stable, level surface within the pond or water feature. Ensure it is fully submerged and not resting directly on soft sediment. Using a pump stand or elevated platform is recommended to prevent clogging from debris.
- Discharge Connection: Connect a suitable discharge hose or pipe to the pump's 3-inch discharge port. Ensure all connections are secure and watertight to prevent leaks and maintain optimal flow.
- Electrical Connection: Route the 20-foot power cord safely, avoiding kinks or damage. Connect the pump to a dedicated 115V, grounded electrical outlet protected by a Ground Fault Circuit Interrupter (GFCI). Do not use extension cords unless absolutely necessary and ensure they are rated for outdoor use and the pump's power requirements.
- Initial Check: Before powering on, verify that the pump is fully submerged and all connections are tight.

6. Operating Instructions
Once the pump is properly installed and submerged, operation is straightforward:
- Power On: Plug the pump's power cord into the GFCI-protected 115V outlet. The pump should start immediately.
- Monitor Flow: Observe the water flow from the discharge. Ensure it is consistent and free of air bubbles, which could indicate an airlock or insufficient water level.
- Continuous Operation: The Tsurumi 12PN is designed for continuous operation in submerged conditions.
- Power Off: To stop the pump, simply unplug it from the electrical outlet.
7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump:
- Disconnect Power: Always unplug the pump from the power source before performing any maintenance.
- Clean Impeller and Volute: Periodically remove the pump from the water and inspect the impeller and volute for debris (leaves, algae, small stones). Clean thoroughly with water and a soft brush.
- Check Power Cord: Inspect the power cord for any signs of damage, cuts, or fraying. Replace if damaged.
- Winterization: In freezing climates, remove the pump from the water before temperatures drop below freezing. Clean it thoroughly and store it in a dry, frost-free location.
- Oil Chamber: The pump's oil chamber contains white mineral oil for lubrication. This is a sealed unit and typically does not require user intervention. If leakage is suspected, contact Tsurumi Pump support.
