    What to do if 'Low Vacuum' is displayed on Tuttnauer 3870 ELV Laboratory Equipment?
    • J
      Jeffery SnyderAug 19, 2025
      If the Tuttnauer Laboratory Equipment displays 'Low Vacuum', this indicates that a vacuum level of 15kPa was not reached within 20 minutes after the cycle started during the air removal stage. To resolve this, try performing a new cycle. If the issue persists, it may be necessary to call a technician, or the bio-hazard filter may be clogged.
