Nitrous Express Purge Valve system (15603) - Manual (Page 2)

Section B - Installation with N2O solenoids that do not have a purge port. (NX Mainline solenoids or
other solenoids that lack a purge port)
1. Disconnect the feed line from the N2O solenoid.
2. Install the AN adapter Manifold between the N20 feed line and the N2O solenoid inlet.
3. Using the supplied union fitting, connect the inlet of the purge solenoid to the 1/8NPT port
on the side of the AN adapter manifold.
4. Plug the purge port of the purge solenoid with the supplied Allen Head pipe plug
5. Connect the 1/8NPT to 3/16 compression fitting into the N2O out port on the purge
solenoid.
6. Insert the 3/16 hard line into the compression fitting and tighten the compression nut.
7. Bend the 3/16 hardline in a direction that will route the purged nitrous out of the engine
compartment. The preferred is venting is at the windshield base so the nitrous flow can be
viewed from the driver’s seat.
8. Continue to section C
Section C – Wiring and testing
1. Wiring the purge valve is easy but care must be taken. One of the two wires on the solenoid will go to
ground, the other will attach to your push button. The other terminal on the push button will go to the
output of your master arming switch.
2. TESTING: Slowly open the bottle valve. Now is the time to check for leaks, if any are seen or heard
tighten the fitting that is leaking.
3. Turn the arming switch on and push the purge activation button; you should hear a click and see
liquid (white) N2O coming from the vent line.
4. Now you are ready to use your new NX purge.
Note: The nitrous and fuel solenoids are rated only for intermittent duty. Do not engage either solenoid
for more than 20 continuous seconds. Solenoids that have “burned or scorched” electro-magnets will
not be replaced under warranty.
