1. Introduction
This manual provides essential information for the safe and efficient operation of your Aquascape Tsurumi 3PL Submersible Pump. Designed for use in skimmer filters and pondless waterfall applications, this pump is engineered for reliability and performance in water garden environments. Please read these instructions thoroughly before installation and use.
2. Safety Information
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury.
- Electrical Safety: Ensure the power cord is connected to a ground fault circuit interrupter (GFCI) protected outlet. Do not cut or modify the power cord. Never operate the pump if the cord is damaged.
- Submersion: This pump is designed for full submersion in water. Do not operate the pump dry.
- Handling: Always disconnect power before handling, installing, or performing maintenance on the pump. Do not lift the pump by its power cord.
- Children and Pets: Keep children and pets away from the pump and water feature during operation and maintenance.
- Intended Use: Use this pump only for its intended purpose in water garden applications. Do not use with flammable liquids or in swimming pools.
3. Package Contents
Verify that all components are present upon unpacking:
- Aquascape Tsurumi 3PL Submersible Pump (Model 29975)
- 20-foot power cord (attached)
4. Setup
Follow these steps for proper installation of your submersible pump:
- Placement: Position the pump in a skimmer filter or pondless waterfall vault. Ensure it rests on a stable, level surface to prevent tipping and allow for optimal water intake. The horizontal design of the PL series pump is optimized for Aquascape filters.
- Discharge Connection: Connect the pump's 2-inch threaded discharge to your plumbing system. Ensure all connections are secure and watertight to prevent leaks and maintain efficient flow.
- Submersion: Ensure the pump is fully submerged in water before connecting to power. Operating the pump dry can cause severe damage.
- Power Connection: Route the 20-foot power cord to a GFCI-protected electrical outlet. Do not use extension cords unless absolutely necessary and ensure they are rated for outdoor use and appropriate amperage.

5. Operating Instructions
Once properly installed and submerged, the Aquascape Tsurumi 3PL pump is designed for continuous duty operation.
- Power On: Plug the pump into the GFCI-protected outlet. The pump will begin to circulate water immediately.
- Thermal Overload Protection: The pump features a built-in thermal overload protector. If the pump runs in low-water conditions or overheats, it will automatically shut off to prevent damage. It will restart once it cools down and normal operating conditions are restored.
- Solids Handling: The semi-vortex impeller design allows the pump to efficiently handle small solids, reducing the frequency of maintenance.

6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
- Disconnect Power: Always unplug the pump from the electrical outlet before performing any maintenance.
- Impeller and Housing Cleaning: Periodically remove the pump from the water and inspect the impeller and pump housing for debris accumulation (e.g., leaves, string algae). Clean any obstructions to maintain efficient water flow.
- Winterization: In regions with freezing temperatures, remove the pump from the water feature before the first hard freeze. Clean the pump thoroughly and store it in a frost-free location, submerged in a bucket of water if possible, to keep seals lubricated.
7. Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power; GFCI tripped; Thermal overload activated; Impeller jammed | Check power connection and GFCI. Allow pump to cool if thermal overload activated. Disconnect power and inspect/clear impeller. |
| Reduced water flow | Debris clogging intake or impeller; Kinked or obstructed discharge hose; Low water level | Disconnect power and clean pump intake and impeller. Check and clear discharge plumbing. Ensure adequate water level in the feature. |
| Pump runs intermittently | Thermal overload cycling due to overheating (low water, excessive debris, high ambient temperature) | Check water level. Clean pump and surrounding area for debris. Ensure proper ventilation if in an enclosed space. |
