Setup and Installation
Follow these steps to properly set up your Fimco High-Flo sprayer pump:
- Mounting: Securely mount the pump to a stable surface using the integrated mounting feet. Ensure the pump is positioned to allow for easy connection of hoses and access to electrical terminals.
- Hose Connections: Connect the inlet hose from your liquid source (e.g., sprayer tank) to the pump's inlet port. Connect the outlet hose to your spray wand or nozzle. Ensure all connections are tight to prevent leaks. The pump features quick attach port connections for convenience.
- Electrical Connection: Connect the pump's 12V DC power leads to a compatible 12V power source (e.g., battery). Ensure correct polarity (red to positive, black to negative). Install a 5 Amp fuse in the positive power line to protect the pump and electrical system.
- Priming: The pump is self-priming up to a certain lift. For best results, ensure the inlet hose is submerged in liquid before starting the pump.
Operating Instructions
Once the pump is properly installed and connected, follow these steps for operation:
- Prepare Liquid: Fill your sprayer tank with the desired liquid, ensuring it is properly mixed according to chemical manufacturer instructions.
- Power On: Connect the 12V power source to the pump. The pump will begin to operate, building pressure.
- Spraying: Activate your spray wand or nozzle. The pump will maintain a flow rate of up to 1.2 GPM and pressure up to 60 PSI, providing consistent spray.
- Power Off: When finished spraying, disconnect the 12V power source from the pump.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump:
- Flushing After Use: After each use, especially when spraying chemicals, FLUSH THE PUMP THOROUGHLY with clean water. For best results, use a tank neutralizer and cleaner such as Fimco #5173005 to remove chemical residues and prevent corrosion.
- Winterization: To prevent damage from freezing, PROTECT FROM FREEZING temperatures. Completely drain all liquid from the pump and hoses before storing in cold conditions. Running a small amount of RV antifreeze through the pump can also provide protection.
- Inspection: Periodically inspect hoses, connections, and electrical wiring for wear, damage, or leaks. Replace any damaged components immediately.
- Cleaning: Keep the exterior of the pump clean and free of debris.
Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power, blown fuse, loose electrical connection. | Check 12V power source. Inspect and replace the 5 Amp fuse if blown. Ensure all electrical connections are secure. |
| Low flow or pressure | Clogged inlet filter, kinked hose, air leak in inlet line, worn diaphragm. | Clean or replace inlet filter. Straighten hoses. Check all inlet connections for air leaks. If diaphragm is worn, replacement may be necessary. |
| Pump runs but no prime | Inlet hose not submerged, air leak in inlet line, pump not self-priming due to excessive lift. | Ensure inlet hose is fully submerged. Check all inlet connections for air leaks. Reduce the vertical lift if possible. |
| Leaking from pump head | Loose screws, damaged O-rings or diaphragm. | Tighten screws on the pump head. Inspect and replace O-rings or diaphragm if damaged. |
