PICTOGRAMS The following symbols will be used in this manual and found on the equipment: Warning: Hazard that can cause death or serious injury. Follow the instructions. Caution: Danger that can cause damage to the equipment. Follow the instructions. Warning: Risk of death due to suffocation. Risk of fire: Oxygen-enriched air leads to an increased risk of fire in the event of contact with flammable products. High pressure risk: Follow the instructions with respect to compressed gasses.
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.
COMPONENTS When the NTO-200 is delivered, check the box to ensure that all items are included. The following is a list of included items: Item # DESCRIPTION QUANTITY 1 NTO-200 Nitrogen TopOFF System 1 2 ¼” NPT Adapter 1 3 Filter Assembly 1 If it is found that anything is missing, or appears damaged, please inform delivery company and contact NTO-200 supplier immediately.
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.
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 the nitrogen inflation process. 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.
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.
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. Indication Condition If error icon is flashing, the pressure sensor is no longer in calibration. Check that membrane cartridge is installed correctly (See section “Replacing Membrane Cartridge”).
TROUBLESHOOTING Fault Probable Cause Solution NTO-200 will only power up for 5 seconds. An error occurred during operation Power up generator and note error codes on display. Refer to previous page for more details No pressure at inlet Check the following: 1.) NTO-200 is connected to compressed air supply. 2.) Compressed air supply pressure meets required specification. 3.) Hoses for any damage. Internal leak Ensure cartridge is correctly installed in grip and lock ring is secure.
TROUBLESHOOTING (Continued) Fault Reduced Purity of nitrogen Tire pressure does not fall when ON/OFF button held in. Pressure continually high. Probable Cause Solution Compressed air supply does not meet specified requirements of ISO 8573-1: 2001 Class 3.-.3 It is not allowed to feed liquid/aerosol/condensate water or oil into NTO-200. Check the following: 1.) Compressor operating correctly and fully maintained. 2.) No contaminants near compressor's intake. 3.
