HAZARDS DEFINED

This manual presents step-by-step instructions that describe the process of installing your NOS Mini 2-Stage Progressive 
Controller. These procedures provide a framework for installation and operation of this kit. Within the instructions, you are 
advised of potential hazards, pitfalls, and problems to avoid. The following examples explain the various hazard levels:

WARNING! Failure to comply with instructions may result in injury or death. CAUTION! Failure to comply with 

instructions may result in damage to equipment. 

NOTE

: This information is important, needs to be emphasized, and is set apart from the rest of the text. 

HINT

: These special instructions provide a handy work tip. 

NITROUS OXIDE INJECTION SYSTEM SAFETY TIPS

 

WARNINGS 
IT IS NOT LEGAL TO ENGAGE NITROUS OXIDE INJECTION SYSTEMS ON PUBLIC ROADS OR HIGHWAYS. 
NITROUS OXIDE INJECTION SYSTEMS ARE ONLY TO BE ENGAGED DURING SANCTIONED COMPETITION OR 
RACING EVENTS. 

Do not attempt to start the engine if the nitrous has been injected while the engine was not running. Disable the 

lutions 

before attempting to start. Failure to do so can result in extreme engine damage. 

Never permit oil, grease, or any other readily combustible substances to come in contact with bottles, valves, 
solenoids, hoses, and fittings. Oil and certain gases (such as oxygen and nitrous oxide) may combine to produce 
a highly flammable condition. 

Never interchange nitrous and fuel solenoids. Failure to follow these simple instructions can result in extreme 
engine damage and/or personal injury. 

Never drop or violently strike the bottle. Doing so may result in an 
explosive bottle failure.  Never change pressure settings of safety relief 
valve on the nitrous bottle valve.  Increasing the safety relief valve 
pressure settings may create an explosive bottle hazard. 

Please note that the NOS bottle label has changed to a two-part 
assembly.  The first label is already located on the bottle.  Upon filling 
your bottle with nitrous oxide, apply the (second) material information 
label in the area indicated in the picture to the right. 

NOTE: The material information decal is located in the same plastic bag 
as the bottle. 

WARNING! Once the nitrous bottle has been filled, it must be shipped 
according to the applicable transportation and shipping regulations! 

Do not deface or remove any markings, which are used for content identification. Nitrous bottle valves should 
always be closed when the system is not being used. 

Notify the supplier of any condition that may have permitted any foreign matter to enter the valve or bottle. Keep 
the valves closed on all empty bottles to prevent accidental contamination. 

fittings. 

It is important that all threads on the valves and solenoids are properly mated. Never force connections that do 
not fit properly.
