INSTRUCTIONS
| Step | Do this | Pass check |
|---|---|---|
| 1 | Remove the factory port plug (or remove the vacuum gauge on a Nemo Grabo) | Port is open; factory nut saved for future removal |
| 2 | Remove the supplied “Joey” nut from the adapter | Threads are clean and ready |
| 3 | Confirm the “Joey” washer is seated against the bottom of the adapter | Washer is flush and centered |
| 4 | Insert adapter through the Grabo body with the washer outside the vacuum chamber (Nemo: enlarge hole as needed, test-fit as you go) | Adapter seats cleanly without forcing |
| 5 | Thread the supplied “Joey” nut onto the adapter | Nut starts smoothly by hand |
| 6 | Tighten to seal (do not over-torque) | Seal is tight; no deformation or damage |
| 7 | Leak test: valve closed, place Grabo on non-porous surface, verify no leaks; then connect system and open valve | No leaks; vacuum holds; system behaves normally |
