Installation guidelines:
Mount using M5 mounting screws with vibration-damping washers.
Maintain 20mm clearance below valve for condensate drainage.
Pipe connections must be torque-limited to 12-15 N·m.
Perform weekly manual cycling during maintenance.
Critical note:
Not compatible with phosphate ester fluids or chlorinated solvents.
Minimum 80% duty cycle required to prevent seal drying.
Always install downstream of pressure regulator.
