Nitrous Express Purge Valve system (15603) - Manual

Purge Valve system part numbers 15600, 15601 and 15603.
The installation of this purge valve will add to the value, consistency, and performance of your NX
system. The purpose of the purge is to remove all gaseous nitrous and air from your main feed line. This
puts liquid nitrous at the N2O solenoid resulting in a harder leave or “hit”.
Before you begin make sure that your bottle valve is closed and your main feed line is empty. Liquid
nitrous can cause severe frostbite if it comes in contact with your skin! Use NX liquid thread sealer on
any NPT fittings. Never use Teflon tape on any fittings of a nitrous system. AN fittings do not require
sealer of any kind.
If your solenoid has a purge port, follow the instructions and diagram in Section A. If your Nitrous
Solenoid does not have a purge port, skip to Section B
Section A – Installation with N2O solenoids that have a purge port. (NX Lightning and Iceman Series
Solenoids)
1. Using the supplied union fitting, connect the inlet of the purge solenoid to the purge port of the
N2O solenoid.
2. Plug the Purge port of the purge solenoid with the supplied Allen Head Pipe plug
3. Connect the 1/8NPT to 3/16 compression fitting into the N2O out port on the purge solenoid.
4. Insert the 3/16 hard line into the compression fitting and tighten the compression nut.
5. 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.
6. Skip to section C
