Setup
Before installation, ensure the pump is placed on a stable, level surface within your water feature. The MD350 is a submersible pump and must be fully submerged during operation to prevent overheating. Connect the appropriate tubing to the pump's outlet. The removable pre-filter should be securely attached. For electrical connection, ensure the 20-foot power cord reaches a GFCI-protected outlet. Always consult local electrical codes and safety guidelines.
For guidance on selecting the correct pump for your specific water feature application, including calculating total dynamic head, please refer to the instructional video below.

Operating
Once installed and connected, the MD350 pump operates by drawing water through its pre-filter and expelling it through the outlet, creating your desired water flow for fountains or features. Its magnetic induction design contributes to energy-efficient operation. Ensure the pump remains fully submerged and the water level is maintained to prevent air intake, which can damage the pump.
Maintenance
Regular maintenance is crucial for the longevity and performance of your MD350 pump. The removable pre-filter should be cleaned periodically to prevent blockages and maintain optimal flow. To access the impeller assembly for cleaning or replacement, simply give the volute a quarter-turn. The oversized ceramic shaft is designed for durability, but inspect it for any signs of wear during maintenance. Always disconnect power before performing any maintenance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not running | No power; tripped GFCI; clogged impeller | Check power supply and GFCI; clean impeller and pre-filter |
