Setup
- Prepare Work Area: Ensure your work area is clean, well-ventilated, and free from contaminants.
- Gather Components: You will need a 3M PPS Mini Liner, a 3M PPS lid with filter, and a 3M PPS hard cup.
- Insert Liner: Place a new 3M PPS Mini Liner into the appropriate 3M PPS hard cup. Ensure the liner is fully seated at the bottom of the hard cup.
- Mix Paint: Pour the desired amount of paint material into the liner. Mix the paint according to the paint manufacturer's instructions.
- Attach Lid: Securely attach the 3M PPS lid with the integrated filter onto the liner and hard cup assembly. Ensure a tight seal to prevent leaks.
Operating Instructions
- Connect to Spray Gun: Attach the assembled PPS system (liner, lid, hard cup) to your compatible spray gun using the appropriate adapter.
- Invert System: Invert the spray gun and PPS system. The liner will collapse as paint is sprayed, maintaining a consistent flow and allowing for spraying at any angle.
- Spray Application: Proceed with paint application according to standard spray gun operating procedures and paint manufacturer guidelines.
- Monitor Paint Level: The transparent nature of the liner allows for easy monitoring of the remaining paint volume.

- Remove the used liner and lid from the hard cup.
- Dispose of the used liner and lid according to local environmental regulations for paint waste.
- Clean the hard cup and spray gun adapter thoroughly with appropriate cleaning solvents.
- Ensure all components are dry before storing or preparing for the next use.
Important: Do not attempt to clean or reuse the disposable liners or lids. This can compromise performance and lead to contamination.
Troubleshooting
