4. Setup and Installation
Follow these steps for quick and proper installation of your diaphragm pump:
- Mounting: Securely mount the pump in a dry, well-ventilated area using the stable bracket. Ensure it is on a flat, stable surface to minimize vibration.
- Inlet Connection: Connect the water inlet hose to the designated inlet port (often labeled 'Inlet' or indicated by an arrow pointing towards the pump). It is recommended to install the included filter on the inlet line to prevent debris from entering the pump.
- Outlet Connection: Connect the water outlet hose to the designated outlet port (often labeled 'Outlet' or indicated by an arrow pointing away from the pump).
- Electrical Connection: Connect the pump's power wires to a 12V DC power source. Ensure correct polarity (red wire to positive, black wire to negative). It is advisable to install an inline fuse for protection.
- Prime the Pump (if necessary): While this is a self-priming pump, ensuring the inlet line is filled with water before the first use can aid in faster priming.
- Check for Leaks: After all connections are made, slowly introduce water into the system and check for any leaks at the fittings. Tighten connections as needed.

5. Operation
Once installed, operating the DXQ FL-40 pump is straightforward:
- Starting the Pump: Ensure all connections are secure and the power source is ready. Apply 12V DC power to the pump. The pump will begin to operate and self-prime.
- Automatic Operation: The pump is designed to automatically turn on when water is demanded (e.g., a faucet is opened) and turn off when the demand stops and pressure builds up in the system.
- Flow and Pressure: The pump delivers a maximum flow of 17 L/min and maintains pressure up to 40 PSI.
- Monitoring: Periodically check the pump for unusual noises, vibrations, or leaks during operation.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump:
- Filter Cleaning: Regularly inspect and clean the inlet filter to prevent clogging and maintain optimal flow. Disconnect power, remove the filter housing, clean the mesh screen, and reassemble.

- Connection Check: Periodically check all hose and electrical connections for tightness and signs of wear.
- Winterization (if applicable): If the pump is used in an environment where temperatures drop below freezing, ensure it is drained completely or protected with RV antifreeze to prevent damage from freezing water.
- General Cleaning: Keep the exterior of the pump clean and free from dirt and debris.
7. Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
