    • C
      charleslucasAug 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.

      If the display of your Tuttnauer Laboratory Equipment is not activated, first, check the power source to ensure it meets the required specifications. Next, verify that the ON/OFF switch is in the ‘On’ position. Also, make sure the power cord is properly connected to both the machine and the mains. Check the reset button on the cut-out thermostat and reset it if necessary. Finally, check if the circuit breaker has tripped and reset it if needed.
