Nitrous Express DRY NITROUS (21000) - Manual (Page 2)

SOLENOID MOUNTING
1. The NX Dry nitrous systems are supplied with the world’s most sophisticated N2O solenoid. Pay special
attention to the “inlet-outlet port arrangement. The inlet port is the location for the N2O filter fitting, the
purge port is for the optional purge valve. If no purge valve is used a 1/8 NPT plug is provided to
block this port.
The nitrous discharge port is marked “outlet port”. The blue 3AN line which goes to the
nozzle should be connected to the “outlet port”.
2. Install all solenoid fittings using the provided liquid red NX thread sealer (NO TEFLON TAPE!) at this
time.
3. The solenoid mounting bracket is designed to be universal. Start by mounting the solenoid bracket to the
base of each solenoid. Do not tighten! You may have to flip the mounting bracket over to align the
solenoid for the proper orientation. Locate an existing screw, bolt, or stud to mount the solenoids.
Choose a location that allows the nozzle feed line some slack to prevent any flow restrictions or
influence on the nozzle. Tighten all mounting screws and mount locations securely now. Note: The
solenoids may be mounted in any position, on their sides or upside down.
4. Thread the N2O steel braided line onto the Nitrous solenoid outlet and to the nitrous nozzle.
5. The bottle-feed line will be attached to the N2O solenoid on the “inlet” side of the solenoid.
ROUTING THE NITROUS FEED LINE
NOTE: Place a piece of tape over the end of the hose to prevent debris from entering the feed line
during the routing process.
The 4AN nitrous feed line may be routed to the engine compartment either through the passenger
compartment or under the vehicle. Route the line carefully to prevent the possibility of restricting nitrous
flow. If routed under vehicle, locate and drill a 3/4 inch diameter hole in a suitable area near the bottle valve
for the main feed line. Starting at the bottle nipple, route the line to the engine compartment. Following
the factory fuel lines is usually the best path. Note: Keep maxi mum clearance between all moving parts,
suspension components and hot engine components, securing the supply line where possible (“Zip Ties”
are the best for securing the feed line). Be especially careful of the feed line being near any “HOT”
electrical leads, one small spark will destroy the Teflon liner causing a nitrous leak. Before you attach the
nitrous supply line to the solenoid, purge the line of any foreign matter that may have accidentally
entered the line during installation. Do so by removing the tape used during installation and blowing
compressed air through the feed line. (Have an assistant hold the end of the hose aimed away from the
truck and any people. Wearing a glove is recommended). Immediately after the purg ing operation, connect
the main feed line to the N2O solenoid and the nitrous bottle, tighten securely
BE SURE ALL NUTS ON SOLENOID MAGNETS ARE TIGHT!
ELECTRICAL HOOK-UP
1. Mount the toggle (Arming) switch in a location that is within easy reach of and in plain sight of the
diver.
2. Using 14-ga. wire and connectors supplied in the switch kit, connect a HOT lead (12 VDC
POSITIVE) to the “Power” terminal of the toggle switch. (Use a 10 amp in line fuse if desired). This
power source must be controlled by the ignition switch (See Wiring Schematic).
3. Connect a grounded wire to the “Ground” terminal of the toggle.
4. The system is furnished with a universal wide- open throttle switch. This WOT micro-switch
is designed to work with the universal mounting bracket. It’s maximum capacity is 10 AMPS and
should only be used to activate low amp draw accessories or in conjunction with a relay.
