3. Pressurise system slowly: turn the rotary knob in the "+" direction until the
desired pressure is reached.
Maintain permissible pressure regulation range è Technical data.
The input pressure p1 should always be at least 0.1 MPa (1 bar, 15 psi) higher
than the set output pressure p2.
4. Lock rotary knob [1] (press).
