4. Turn both valves on NTF unit to “FILL TIRE”
5. Connect hoses to tires
6. Set the final target pressure by pressing + or - buttons
7. To change Over Pressure and Nitrogen Purge Cycles
Settings, see sections below
8. Move “Red” slider valve to up position

or
hold N2 button to invoke Nitrogen Purge Cycle
- Standard Inflation will inflate or deflate to the
target pressure
- One complete Nitrogen Purge Cycle is the
process in which the Auto Tire Fill System will
deflate to 3 PSI, Inflate to target pressure, deflate
to 50% of target pressure, then inflate to final target
pressure (If 2 or more Nitrogen Purge Cycles are
programmed, the above process will be repeated)
10. When unit beeps 5 consecutive times, slide “Red”
valve to down position
11. Wait 10 seconds before disconnecting hoses

Error Messages
Error Possible Cause Solution
ER1 Unstable pressure Verify that air chuck is pressed
all the way onto the tire
ER2 Unstable pressure,
incorrect supply pressure,
or Inflate/deflate valve
connections are reversed Verify that air chuck is pressed
all the way onto the tire. Check
valve connections on PCB.
ER3 Low or no supply pressure Verify that air chuck is pressed
all the way onto the tire
ER4 Initial or final pressure is
too high, exceeds
maximum pressure by
more than 20 psi, 140
kPa, or 1.4 bar Turn bottom valve on NTF unit
to vacuum tire. Turn off power
for a minimum of 5 seconds. If
error reappears, call RTI
ER5 Low supply voltage Check power supply, message
will clear when correct voltage
is restored
ER6 Program or PCB error Turn off power for a minimum of
5 seconds. If error reappears,
call RTI
ER8 Calibration error Calibration required, call RTI
ER9 Calibration error Turn off power for a minimum of
5 seconds. If error reappears,
call RTI
Troubleshooting
Problem Possible Cause Solution
No Display No power supply to
Auto Inflation Unit Check power
supply
The display will not
move or is stuck on a
particular value Switch is damaged Call RTI
The unit deflates very
slowly The silencer plug on
the valve is blocked Remove and clean
silencer plug
The Auto Inflation
Unit no longer beeps The beeper is
damaged Call RTI
The inflation process
commences but does
not complete Low supply pressure Verify that air chuck
is pressed all the
way onto the tire
