This sign can be seen after opening the door.
Important safety tip
This prompts the operator this part is the important safety information.
Security considerations：
Please read the safety warnings and precautions provided in this user guide to ensure that you use
the autoclave safely. If you do not follow the instructions provided in the manual, the protection
offered by the equipment may be damaged.
1. Use a separate protective earthing power socket of three holes 220V/10A, and make sure the
protective earthing terminal to a reliable connection.
2. Insert the autoclave power plug completely into the power socket, and do not use the power other
than those specified.
3. Do not use wet hands to pull the plug.
4. Do not damage, modify, stretch, or excessively bend or twist the power cord, but also do not put
heavy objects on the power cord.
5. Do not place the autoclave on an unstable table, such as a shaky table, ramps or the will-shake
position.
6. Do not block or cover the autoclave door, air vents,or heat-sink window.
7. Do not put anything on the autoclave.
8. If you find autoclave is smelly or unusual noisy in the using process, immediately turn off the
power. Then please contact your local dealer or our sales and service department
9. If the autoclave is not to be used for a period of time, the power cord plug should be power off
and remove the battery of the main board.
10. Do not place the autoclave near the heat source.
11. The LCD screen may work unstably if there is interference in the power grid when the equipment
is in use. The operator can equip it with a voltage regulator in order to solve the above problems.
12. Autoclave package (or product) must be accompanied by chemical indicator.
13. Autoclave is not suitable for sealing liquid, the product that is not resistant to high temperature
and high pressure.
14. Users should confirm the local altitude when using for the first time. If the altitude is more than
200 meters, the highland setting should be modified. Detailed operation please check the 6.3.2
