4. Safety Information
- Always ensure the power source matches the pump's voltage (12V DC).
- Do not operate the pump with flammable liquids.
- Ensure all connections are secure before operation to prevent leaks and electrical hazards.

- Do not direct the spray at people, animals, or electrical components.
- Disconnect power when not in use or during maintenance.
- Store the unit in a dry, protected area when not in use.
5. Setup
- Unpack the Kit: Open the heavy-duty portable case and remove all components.
- Connect Inlet Hose: Attach the 2M inlet hose to the pump's inlet port. Ensure the filter end of the inlet hose is submerged in the water source (e.g., lake, bucket, tank).
- Connect Outlet Hose & Nozzle: Attach the 6.5M UV-protected coiled outlet hose to the pump's outlet port. Securely attach the adjustable sprayer nozzle to the other end of the coiled hose.
- Connect Power: Plug the 12V DC wire assembly into a compatible cigarette lighter socket on your boat, RV, or vehicle. The pump features an integrated on/off switch on the wire assembly for convenient control.

6. Operating Instructions
- Prime the Pump: Ensure the inlet hose is fully submerged in water and the outlet hose is clear.
- Turn On: Activate the pump using the on/off switch located on the wire assembly. The pump will begin to draw water.
- Adjust Spray: Use the adjustable sprayer nozzle to control the water flow and spray pattern, from a fine mist to a powerful jet.
- Bypass Valve: The built-in bypass valve ensures smooth operation and reduces pump cycling when the nozzle is closed or flow is restricted, maintaining consistent pressure without excessive wear on the pump.
- Shut Off: When finished, turn off the pump using the switch on the wire assembly.

7. Maintenance
- Rinsing: After each use, especially with saltwater or dirty water, flush the pump and hoses with clean fresh water to prevent mineral buildup and corrosion.
- Filter Cleaning: Regularly inspect and clean the inlet filter to ensure optimal water flow and prevent debris from entering the pump.
- Hose Care: Coil the UV-protected hose neatly after use to prevent kinks and damage.
- Storage: Store the entire kit in its heavy-duty portable case in a cool, dry place, protected from extreme temperatures and direct sunlight.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not turning on | No power, loose connection, faulty switch. | Check 12V power source, ensure cigarette lighter plug is fully inserted, verify switch is in "ON" position. |
| Low or no water pressure | Clogged inlet filter, kinked hose, air in system, low water source. | Clean inlet filter, straighten hoses, ensure inlet hose is fully submerged, prime the pump. |
| Pump runs continuously (does not shut off) | Leak in system, bypass valve issue. | Check all connections for leaks. Ensure nozzle is fully closed. If problem persists, contact support. |
| Water leaking from connections | Loose fittings, damaged O-rings. | Tighten all quick-attach fittings. Inspect and replace O-rings if damaged. |
