- Connect the Ethernet cable or the Wi-Fi dongle key in the rear of the sterilizer.
- Attach the power cord to the socket in the rear of the sterilizer and route the cord through the cable guides.
- Connect the power cord to a wall outlet. For power supply requirements, see “Technical data” on page 95.
- Connect the compressed air tube (Ø 6 mm) in the rear of the sterilizer (only for Lexa MINI equipped with ejector). Note: make sure the tube is inserted correctly into the quick fitting to avoid leaks.
