Lube the exhaust nipple, drop the unit in slowly (do not force it) screw it in (finger tight), fill to </= 2Kpsi and you're ready. The spring is no longer included. Your kit comes with a valve seal and steel ball. Place the ball in the striker for added spring tension. Replace the valve seal if desired.
CAUTION: This is not an install, pump to 3Kpsi, start shooting setup. Consult with actual users @ PowerMax HiPAC on Facebook for necessary modifications and how to do them safely.
