IMPORTANT INSTALLATION NOTES:
✔ Confirm the two 3/8" supply ports, two 3/8" delivery ports, and one 1/4" control port.
✔ Position the control port at 90° relative to the delivery ports.
✔ Mount using two 0.34" holes on 1.50" centres and confirm bracket compatibility.
✔ Install the supplied 3/8" NPT plug in the unused connection required by the system layout.
✔ Verify the 5.6 PSI ± 1.0 PSI crack pressure, then leak-test brake application and release.
