Kromschroder 84447031 DG150UG-4K2 differential pressure switch maintenance

To ensure smooth operation:

• Verify the tightness and functionality of Krom schroder DG150UG-4K2 84447031 gas pressure switch annually, or every six months if it operates with biogas.
• Conduct a functional check, particularly for decreasing pressure control, for example, using the PIA.
• After performing maintenance work, ensure to check for any leaks in the system.
