4. Setup and Installation
4.1 Submerged Installation
- Placement: Position the pump on a stable, level surface within your water feature. Ensure it is fully submerged in water and away from heavy debris that could clog the pre-filter.
- Hose Connection: Attach appropriate tubing (3/4", 1", or 1 1/4" diameter) to the multi-size hose adapter on the pump's outlet. Secure with a hose clamp (not included) if necessary.
- Electrical Connection: Route the power cord safely to a grounded GFCI outlet. Avoid kinks or damage to the cord. Do not plug in the pump until all connections are secure and the pump is fully submerged.
4.2 Inline Installation
The pump can also be used outside the water feature for inline applications, provided it is primed correctly.
- Positioning: Place the pump on a stable, dry surface near the water source. Ensure it is below the water level of the source to facilitate priming.
- Inlet/Outlet Connections: Connect tubing to both the inlet (side opening) and outlet (top opening) of the pump. Ensure all connections are watertight.
- Priming: Before starting, ensure the pump housing is filled with water. This may require manually filling the inlet tubing and pump housing until water flows out the outlet.
- Electrical Connection: Connect the pump to a grounded GFCI outlet only after it is fully primed and all connections are secure.

5. Operating Instructions
- Initial Start-up: Once the pump is installed and connected to a grounded GFCI outlet, plug it in. The pump should start immediately.
- Adjusting Flow Rate: This pump features an adjustable flow rate. Locate the flow control lever or dial on the pump (typically near the inlet). Rotate or slide it to increase or decrease the water flow to achieve the desired effect for your water feature.
- Monitoring: Observe the pump's operation for the first few minutes to ensure proper water flow and no unusual noises.
- Shut-down: To turn off the pump, simply unplug it from the electrical outlet.
6. 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 Pre-filter: The pump is equipped with a removable pre-filter. Periodically remove the pre-filter and rinse it thoroughly under clean water to remove accumulated debris. The frequency depends on the water quality and debris level in your feature.
- Inspect Impeller: If flow decreases or the pump makes unusual noises, the impeller may be obstructed. Remove the pump housing cover and carefully inspect the impeller for debris (e.g., leaves, string, small stones). Clean the impeller and its chamber. The ceramic shaft impellers are replaceable if damaged.
- Winterization (for outdoor use): In freezing climates, remove the pump from the water feature before the first freeze. Clean the pump thoroughly and store it in a frost-free location, submerged in a bucket of water, or completely dry.
