SAFETY INFORMATION
GENERAL SAFETY
Correct use of the NTO-200 Nitrogen TopOFF is important for your
personal safety and for trouble-free functioning. Incorrect use can cause
damage to the NTO-200 or can lead to incorrect gas supply to the
customer’s process.
Warning: Read this manual before you start
operating the NTO-200 to prevent accidents and
damage. If you detect a problem that you cannot
solve with this manual, contact RTI Technical
Support at 1-(800)-468-2321 x 1.

SAFETY INFORMATION (Continued)
COMPRESSED AIR
Warning: Ensure that the feed air pressure does
not exceed 160 psig.
The user is ultimately responsible for selecting the
correct air supply system and components. They
are also responsible for maintaining the system so
it does not cause damage to the NTO-200.
NITROGEN AND OXYGEN
The NTO-200 generates nitrogen as a product. Oxygen enriched air is
released as waste.
Warning
Nitrogen can cause suffocation. Oxygen enriched
air leads to increased risk of fire in the event of
contact with flammable products. Make sure that
there is adequate ventilation at all times!
Do not install the NTO-200 in an area where
explosive substances may be present.
OTHER IMPORTANT SAFETY INFORMATION
Warning: There are no user maintainable parts on
the NTO-200. The grip is part of the pressure
chamber and so it should not be disassembled.
Failure to follow these warnings could result in an
unexpected release of pressure, causing serious
injury or damage.
Use of the NTO-200 in any other way than
specified in this manual could result in an
unexpected release of pressure, causing serious
injury or damage.
Warning: When handling, installing, or operating
the NTO-200, user must use safe engineering
practices and observe all related rules and
health/safety information.

INTRODUCTION
The NTO-200 is a hand held, battery powered nitrogen tire inflation
system created primarily for tire top-offs and small tire fills such as
motorcycle and bicycle tires. It is well-suited for other types of nitrogen
inflation of small pneumatic tires found in the industrial, recreational and
agricultural industries. The NTO-200 can also be used to nitrogen inflate
a wide variety of sporting goods equipment and any other applications
that utilize pneumatic pressure for support.

CHANGING DISPLAY UNITS
Warning: Ensure the NTO-200 is relieved of
pressure before changing units.
The membrane cartridge must be removed from grip before changes can
be made to the setup. Unscrew locking ring from the grip and remove
the cartridge. (Note: This will create error message E4 when grip is
powered up. It will clear itself when the NTO-200 is reassembled.)
Press and hold ON/OFF button until desired units (bar/psi/MPa) are
shown on the display. Release button to save the new unit setting and
turn off NTO-200. (Note: If you scroll through all the units back to
current setting, the NTO-200 will automatically shut down.)
RESETTING ZERO POINT
To reset the zero point of the NTO-200, unscrew locking ring and remove
cartridge. Press ON/OFF button, the NTO-200 will power up and will
reset the zero point. After this is complete, it will automatically shut
down.
SETTING UP AIR SUPPLY
Before performing Nitrogen fills with the NTO-200, customer must first
set up the compressor to supply the NTO-200 with clean, dry (oil less
and waterless) air. To do this effectively, RTI Technologies has supplied
a filter with ¼” NPT ports to install in air supply.
When installing the filter, mount so the automatic drain is pointing
downwards. This drain will automatically bleed any fluids that collect in
the bowl when it detects a certain amount present.
After the filter is installed, the customer should take the ¼ BSPP x ¼
NPT fitting (Item 10 on previous page) and install it on the back side of
the NTO-200 grip, (Item 1 on previous page). NOTE: The customer
must also provide the hose that connects the filter to the NTO-200
grip assembly.

INFLATING TIRES
Warning: The maximum tire pressure
capability for the NTO-200 is 5.5bar / 80psi /
0.55MPa. Small tire sizes inflate very quickly.
Make sure you do not over-inflate tires during
Begin by connecting filtered air supply (Figure 1). Then push down
thumb lever on air chuck at end of Nitrogen Fill Hose. While holding in
lever, push onto valve stem and then release (Figure 2). Press ON/OFF
button to turn on NTO-200. Hold the NTO-200 as shown in Figure 3
below and squeeze the Nitrogen inflation button to fill tires with nitrogen.
Fill tire to pressure specified by manufacturer.
NOTE: The pressure displayed (when squeezing inflation button)
represents the filling pressure; not the tire pressure. To view tire
pressure, user must release inflation button.
Continue filling tire and checking tire pressure until desired pressure is
achieved. If the tire goes above desired inflation value, press and hold
ON/OFF button to release pressure from inside tire. Check tire pressure
by releasing ON/OFF button periodically. When desired pressure is
achieved, disconnect air chuck from tire by squeezing thumb lever and
pulling off valve stem. Replace valve cap (Figure 4).
NOTE: If tire has been filled with compressed air, fully deflate using
appropriate valve release tool. Then inflate to target pressure using
the NTO-200, deflate to 50% of target pressure and refill to target
pressure. This technique increases nitrogen purity in the tires.

REPLACING MEMBRANE CARTRIDGE
When the cartridge’s usable life is diminished, (code E6 will be on the
display) it will need to be replaced.
Disconnect air supply from NTO-200 (Figure 5) and remove Nitrogen fill
hose from end of cartridge. Next, unscrew locking ring from grip (Figure
6) and remove cartridge from grip cautiously (Figure 7). Use caution
when removing the cartridge as to not damage electrical contacts.
Remove gasket from grip and insert replacement. Make certain gasket
is correctly placed in the profile of the grip to obtain best seal (Figure 8).
When installing replacement cartridge, ensure that key on side of
cartridge is aligned with groove inside grip.
Confirm the key is
aligned with groove
inside grip before
tightening lock ring.
Carefully push cartridge into grip and use lock ring to hold in place. The
lock ring must be fully engaged before continuing use of product. Make
sure the lock ring is completely tightened to ensure proper nitrogen
purity. Insufficient tightening will lead to a reduction in nitrogen
purity.
Remove nitrogen fill hose from old membrane and reconnect to new
membrane. Torque fitting to 15 ft-lbs.

MAINTENANCE
There are no serviceable parts on the NTO-200.
The NTO-200 should be wiped down with a damp cloth only. Keep
excessive moisture from the area around the display. A mild detergent
may be used for heavy dirt. Do not use abrasives/solvents as they may
damage the NTO-200. NOTE: Keep clothes away from exhaust
holes and fibers located under locking ring.

ERROR MESSAGES
The warnings below will appear on the display when NTO-200 is
operated outside the limits specified in the technical specifications
section of the manual. The warnings will automatically clear themselves
when the NTO-200 is back to normal operating parameters.
