Recommendation

The equipment cannot be covered in small object while working, in case that the high temperature damages the
control system.
When the equipment is working or its temperature hasn't cooled down to the room temperature, make sure not
to touch the heating board.
Observe all warning labels and never remove them.
Never operate damaged equipment.
Must leave a distance above 100mm around the equipment, if the distance is too short, it may cause articles
around to be damaged.

It's better to consult the engineers of our company before performing maintenance; wrong action may damage
the equipment and void the manufacturer's warranty.

Other Information

1. If your unit belongs to EHD series, you will see 5~10°C temperature pulse when the temperature is lower
than 150°C, so please carefully setup and adjust the temperature.
2. The working temperature of polypropylene tube cannot exceed 130°C.
3. The working temperature of PTFE tube cannot exceed 210°C.
4. The working temperature of 18 positions heating rack with Teflon coating cannot exceed 210°C.
5. Please carefully control temperature when using acid HClO4. The temperature should not exceed 130°C if
sample includes quite big organic components. It is appropriate to increase the temperature above 180°C
when the sample decomposition is basically finished.
6. The digestion reaction will be very strong if the sample includes quite big organic components. We
recommend not to cover the tube.
7. Glass vessels are not easy to uncap after heating. Let the tube cup cool down to ambient temperature.
8. For applications where an EHD unit must work constantly over 12 hours, it is recommended to set
temperature not higher than 380°C.
