IMPORTANT INSTALLATION NOTES:
✔ Mount directly to the trailer reservoir using the 3/4" male NPT connection.
✔ Confirm the supply, service, delivery, reservoir, and exhaust port routing before installation.
✔ Apply air-system-compatible thread sealant without allowing sealant to enter the valve.
✔ Pressurize the system and verify spring brake release, emergency application, and anti-compounding.
✔ Do not substitute an SR-1 valve without confirming the complete reservoir plumbing configuration.
