MANUAL SINGLE TIRE VACUUM AND FILL
VACUUM TIRE
1. Install deflators and check for foreign substances as explained earlier.
2. Connect shop air to the air inlet port on the rear of the NTF-515. Verify pressure indicated on panel
mounted Air Pressure gauge is between 120 - 150 PSI.
3. Turn both panel valves to VACUUM TIRE.
4. Remove deflator and connect Digital Pressure Gauge (on the end of the NTF-515 coiled green
hose) to the tire valve stem. Squeeze handle to vacuum the tire. Periodically release the handle to
observe the vacuum level. Do not vacuum to a level where the tire starts to deform.
Contact RTI Technical Support at 800-468-2321 for further details.
If your application requires an inlet pressure of 100 - 119 PSI, an adjustment to the
automatic pressure switch may be required.
FILL TIRE
1. Connect shop air to the air inlet port on the rear of the NTF-515. Verify pressure indicated on panel
mounted Air Pressure gauge is between 120 - 150 PSI. Verify Nitrogen pressure indicated on the
panel mounted N
2
Pressure gauge is adequate for service.
2. Turn both panel valves to FILL TIRE.
3. Connect Pressure Gauge (on the end of the NTF-515 coiled green hose) to the tire valve stem.
Squeeze handle to fill tire. Periodically release the handle to observe the pressure level. Stop when
the pressure reaches the tire manufacturer’s recommended inflation pressure. Do not over inflate.
4. Install an RTI N

Cap (Package of 200 - Part Number 355-80026-00).
Note: While not using the NTF-515 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-515, 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.
