If the MELAG Vacuklav 24 B+ shows a vacuum system error after a power outage, check the following:

- Inspect the door seal and chamber flange for cleanliness; clean if contaminated.
- Check the door seal for damage and replace if necessary.
- Ensure the door seal is correctly inserted.
- Repeat the vacuum test with the device completely cold.

If the leakage rate remains above the maximum permissible value (1.3 mbar), contact MELAG customer service.

■ Use the steam sterilizer only for the intended purposes outlined in the related technical documents and only in connection with the devices and components approved by MELAG. Warning! ■ The sterilization of instruments and textiles with this steam sterilizer, like the foregoing instrument preparation, is only to be done by competent personnel.
Page 8 Chapter 1 – Performance Specification Automatic pre-heating The cold chamber is preheated on activation of preheating or can be maintained at a specific temperature between two sterilizations. This shortens the program time periods and reduces the formation of condensate to give improved drying results. The steam sterilizer functions according to the feed water one-way Clean feed water according system.

Page 21: Load The Steam Sterilizer
NOTICE: Use perforated trays, such as the trays from MELAG. Only this way can condensate run off. If you use closed materials or shell halves to bear the items to be sterilized, you risk bad drying results. Please note that the use of tray insertions made of paper can perhaps likewise lead to worse drying results.
Page 22 Chapter 4 – Sterilization ■ When stacking the sterilization containers, take care that the perforations are not covered. Danger! in case of non-observance, the condensate cannot drip off to the vessel bottom. It would soak sterilizing materials lying underneath. The consequence would be bad drying results. This can ultimately lead to unsterile instruments and thereby to endangering the health of the patient and the practice team.
