IMPORTANT INSTALLATION NOTES:
✔ Designed for pre-FMVSS-121 trailer systems with single service brake chambers.
✔ Charging-style design fills reservoir directly from the supply line (no pressure protection).
✔ Do not use on converter dollies, lift axles, or turntable axle applications.
✔ Verify 4.5 PSI crack pressure and port sizes before installation.
✔ KN30400 and KN30400X valves can also be used for this application.
✔ Plug unused ports and use approved NPT thread sealant.
