Vacuum Tire
1. Install deflators and check for foreign substances as explained on the preceeding page.
2. Connect shop air (100 - 150 PSI) to the air inlet port on the rear of the NTF-15. If your application requires an inlet
pressure of 100 - 119 PSI, an adjustment to the automatic pressure switch may be required. Contact RTI Technical
Support at 800-468-2321 for further details
3. Turn both panel valves to VACUUM TIRE.

Cap (Package of 200 - Part Number 355-80026-00).
Note: While not using the NTF-15 to fill or vacuum tires, generate Nitrogen and increase the Nitrogen
pressure in the internal storage tank by turning both panel valves to STANDBY.
Note: While using the NTF-15, the automatic drain feature of the filters may activate to remove excess
water and oil. This is normal with the standard operation of the unit.
