4. Setup and Installation
Follow these steps to properly install your Aquatrance 3000S Skimmer Pump:
- Unpack: Carefully remove the pump and all components from the packaging. Inspect for any signs of damage.
- Familiarize: Identify the pump body, impeller, volute, air intake, and output connection.
- Connect to Skimmer: The pump is designed for direct connection to Reef Octopus Classic Protein Skimmers with large grey threaded outputs. Screw the pump's output connection securely onto the skimmer's inlet. Ensure a tight, leak-free seal.
- Attach Air Line: Connect the provided clear air tubing to the pump's air intake barb. The other end of the air tubing will typically connect to the skimmer's air silencer or air adjustment valve.
- Position Skimmer: Place the protein skimmer with the attached pump into your sump or desired location, ensuring the pump is fully submerged in water.
- Power Connection: Route the power cord safely, avoiding kinks or sharp bends. Plug the pump into a grounded electrical outlet with a drip loop to prevent water from traveling along the cord to the outlet.
5. Operation
Once installed, operating the pump is straightforward:
- Initial Start-up: After plugging in, the pump will begin to draw water and air, initiating the skimming process. It may take a few hours for the skimmer to break in and produce stable foam.
- Air Adjustment: If your skimmer has an air adjustment valve, you can fine-tune the air intake to achieve optimal foam production. Refer to your skimmer's manual for specific adjustment instructions.
- Water Level: Ensure the water level in the sump or skimmer chamber remains consistent for stable performance. Fluctuations can affect skimming efficiency.
- Shut Down: To turn off the pump, simply unplug it from the power outlet.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump:
- Routine Cleaning (Monthly/Bi-monthly):
- Unplug the pump from the power source.
- Disconnect the pump from the skimmer body and remove it from the water.
- Disassemble the volute/pump head and carefully remove the impeller.
- Clean all components (impeller, impeller shaft, pump body interior, volute) using a brush and warm water. For stubborn deposits, a mild vinegar solution can be used to soak the parts for a few hours, then scrub clean.
- Rinse all parts thoroughly with fresh water before reassembly.
- Reassemble the pump, ensuring all parts fit correctly.
- Air Line Maintenance: Periodically check the air line and air silencer for blockages from salt creep or debris. Clean as necessary to ensure unrestricted airflow.
- Power Cord Inspection: Regularly inspect the power cord for any signs of damage, fraying, or exposed wires. Replace the pump immediately if damage is found.
7. Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not starting/no power. | No power to outlet; damaged power cord/plug; impeller jammed. | Check power outlet; inspect cord for damage (replace if damaged); clean impeller and pump housing. |
| Reduced air draw/skimming. | Air line or air silencer clogged; dirty impeller; incorrect water level. | Clean air line/silencer; clean impeller; adjust water level in sump/skimmer chamber. |
| Excessive noise/vibration. | Impeller worn or damaged; debris in pump; pump not seated properly. | Inspect and clean impeller; remove debris; ensure pump is stable and securely connected. |
| Pump running, but no water flow. | Impeller jammed or broken; air lock; pump not fully submerged. | Clean/replace impeller; ensure pump is fully submerged and free of air bubbles. |
If the problem persists after attempting these solutions, please contact customer support.
