2. Safety Information
Please read and understand all instructions before operating this pump. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Always disconnect the pump from the power supply before handling or performing any maintenance.
- Ensure the pump is fully submerged in water during operation to prevent overheating.
- Do not operate the pump with a damaged cord or plug. If the cord is damaged, it must be replaced by the manufacturer or a qualified service agent.
- This pump is designed for use with water only. Do not use with flammable liquids.
- Keep children and pets away from the water feature during operation.
- Ensure the electrical outlet is properly grounded and protected by a Ground Fault Circuit Interrupter (GFCI).

Verify that all components are present and undamaged:
- Atlantic Water Gardens FP300 Pump
- Assorted Nozzle Adapters (typically 3 sizes)
- Instruction Manual
4. Setup
Follow these steps to set up your FP300 pump:
- Inspect the Pump: Before installation, visually inspect the pump for any signs of damage.
- Choose an Adapter: Select the appropriate nozzle adapter for your tubing size. The pump typically comes with three different sizes to accommodate various plumbing setups. Screw the chosen adapter onto the pump's outlet.
- Connect Tubing: Attach your water feature's tubing to the installed adapter. Ensure a secure connection to prevent leaks.
- Placement: Place the pump in the desired location within your water feature. The pump is designed for submersible use and should be fully immersed in water. The strong suction cups on the base of the pump allow for secure mounting to the bottom or side of your water feature.
- Adjust Flow Control: The pump features an integrated flow control valve. Adjust this valve to achieve your desired water flow rate.
- Power Connection: Once the pump is securely placed and connected to the tubing, plug the power cord into a properly grounded GFCI outlet.

5. Operating the Pump
Once installed, the FP300 pump is designed for continuous operation. Ensure the water level in your fountain or water feature is always sufficient to keep the pump fully submerged. The pump features an auto shut-off system that activates if the water level becomes too low due to evaporation, protecting the pump from dry running damage.
To adjust the flow rate, locate the flow control valve on the pump and turn it to increase or decrease the water output. This allows you to customize the water flow to suit your specific water feature and desired effect.
For optimal performance and to select the correct pump for your specific water feature application, it is crucial to calculate the Total Dynamic Head (TDH). The TDH is the measure of work your pump will have to perform, considering factors like the width of your waterfall, tubing length, and vertical head height. Refer to the following video for a detailed guide on calculating TDH.
Video 3: This official Atlantic Water Gardens video provides a comprehensive guide on 'Choosing the Perfect Pump' by calculating the Total Dynamic Head (TDH). It explains how to determine the required flow (GPH), select appropriate tubing and multiplier, add equivalent tubing lengths, calculate friction head, and finally, find the TDH to choose the most efficient pump for your water feature.
6. Maintenance
Regular maintenance will ensure the longevity and efficient operation of your FP300 pump:
- Filter Cleaning: The pump is equipped with a removable and washable foam filter. Periodically remove the filter and rinse it thoroughly under clean water to remove any debris, algae, or sediment. A clogged filter can reduce pump performance and lead to premature wear.
- Impeller Inspection: Over time, the impeller may accumulate debris or show signs of wear. The impeller assembly can be replaced quickly without tools. Refer to the pump diagram for instructions on accessing and replacing the impeller.
- Winterization: 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 to keep seals moist, or completely dry if recommended by the manufacturer.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not operate | No power; clogged impeller; damaged impeller; low water level. | Check power connection and GFCI; clean impeller; replace impeller; ensure pump is fully submerged. |
| Low water flow | Clogged filter; kinked tubing; flow control valve closed; insufficient water level. | Clean filter; straighten tubing; open flow control valve; add water to feature. |
| Pump is noisy | Debris in impeller; pump not fully submerged; pump vibrating against surface. | Clean impeller; ensure full submersion; reposition pump or use dampening material. |
