Safety instructions for evaporation
The following instructions must be observed prior to every evaporation
process:
WARNING
• Ensure that the RVC was set up and connected properly (see chapter
• Maintain a safety distance of at least 30 cm (12 inches) around the
RVC.
• Do not store any dangerous goods in the safety area of the RVC.
• Do not stay in the safety area longer than what is absolutely necessary
for the operation of the RVC.
• Only use accessories that have been approved by the manufacturer
(except for commercial vessels made of glass or synthetic materials).
We explicitly warn against the use of equipment of poor quality.
Breaking glass or bursting vessels can cause dangerous imbalances.
• Observe the instructions on the installation of accessories (see chapter
6.4.3 - "Installation of accessories").

Safety devices
3.7.1
Lid lock device
The RVC can only be started when the lid is properly closed. The lid can
only be opened when the rotor has stopped. If the lid is open, the RVC
cannot be started.
3.7.2
System check
An internal system check monitors the data transfer and sensor signals with
regard to plausibility. Errors are detected by continuous self-monitoring of
the system. Error messages are displayed in the process & equipment info
menu (see (see chapter 6.5.3.2 - "Process and equipment information") or
(see chapter 7.1.2 - "Process messages")).
3.7.3
Power failure safety
The unit stores the current process parameters cyclically. In the event of a
power failure, the electromagnetic stop valve towards the vacuum pump will
close automatically, and the rotor decelerates brakeless. The rotor chamber
will not be aerated. After the restart of the power supply, the evaporation
process continues with the last stored parameters.
3.7.4
Earth conductor check
For the earth conductor check, there is an equipotential bonding screw on
the rear panel of the RVC. An earth conductor check can be carried out
with the aid of a suitable measuring instrument.
