The Chapin EZ Mount 12-Volt Sprayer is designed for spot spraying applications. Before use, ensure the wiring harness is not pinched or damaged. Always wear protective gear, including goggles, gloves, long sleeves, and pants. Do not use with flammable, caustic, acidic, chlorine, bleach, or petroleum-based chemicals. For technical support or replacement parts, call 1-800-950-4458.
Assembly Instructions
Suggested Tools: Allen wrench
Nozzle/Wand Assembly:
- Screw the nozzle assembly onto the male threaded end of the extension wand.
- Screw the female threaded end of the extension wand onto the shut-off assembly.
- Tighten the retaining nut securely.
Operation
The system draws solution from the tank through a strainer to the pump. The pump features a pressure switch that automatically shuts it off when it reaches 60 PSI. Regularly inspect the suction supply screen inside the tank and flush with water to clear any accumulated debris.
After Spraying and Cleaning
To maintain the pump and system:
- Fill the sprayer partially with water and run it to flush the plumbing system and spray wand.
- Refill the tank halfway with clean water and a chemical neutralizer, then flush the entire system again.
- Follow the chemical manufacturer's instructions for disposing of all wash or rinse water.
Winter Storage
To prevent damage from freezing and chemical residue:
- Drain all water and chemicals from the sprayer, paying special attention to the pump and valves.
- Pump a solution of RV antifreeze through the entire plumbing system before storage.
Troubleshooting
If you encounter issues, check the following:
- Pump won't start: Verify 12-13V power, check electrical connections, fuse/breaker, and pressure switch operation.
- Pump won't prime: Check for debris in the strainer, kinks in inlet/outlet tubes, or debris in valves.
- Pump won't shut off: Check for air trapped in the line, leaks, or pressure switch adjustment.
- Pump makes noise but no output: Prime the pump by removing the intake hose and flooding it with water while running.

- Pump: 2-chamber positive displacement diaphragm pump, self-priming.

Practical help
Common problems
Pump will not start
Check for correct voltage (12-13V), inspect electrical connections, check the in-line fuse, and ensure the switch is in the 'on' position.
Pump will not prime
Check for debris in the suction strainer, kinks in the inlet/outlet tubes, or debris/swelling in the inlet/outlet valves.
Pump will not shut off
Check for air trapped in the outlet line, leaks in the system, or adjust the pressure switch.
Fuse blows repeatedly
Check for excessive voltage, improper pressure switch adjustment, or a damaged wiring harness.
Before use
- Verify all electrical connections are secure.
- Ensure the power switch is in the 'on' position.
- Check that the voltage is between 12-13V.
- Inspect the suction supply screen inside the tank for debris.
- Ensure the wiring harness is not pinched or damaged.
