3. Monitoring: Match an optional supervisory switch for remote status control.

Maintenance and regulatory compliance

To ensure long life, we recommend:

• Check the EPDM gaskets regularly.
• Lubricate the stem and moving parts to prevent wear.
• In the absence of CE certifications, evaluate the adaptation through a technician for compliance with current regulations.
