IMPORTANT INSTALLATION NOTES:

✔ Ensure vertical orientation of the valve with exhaust port facing downward
✔ Torque cover cap screws to 80–120 in-lbs during assembly
✔ Torque exhaust cover screws to 20–30 in-lbs
✔ Lightly lubricate relay piston, o-rings, guide post, and cover bore with silicone-based grease (Dow Corning 55-M or equivalent)
✔ Do not re-torque after initial assembly – use specified torque values only at assembly time
