3.6.6 Safety Instructions for Evaporation
For safe operation, observe the following before starting the rotational
vacuum concentrator:
Ensure that the rotational vacuum concentrator was set up
properly (see chapter 5 "Set-up and Connection“).
Maintain a safety distance of at least 30 cm (12 inches) around
the rotational vacuum concentrator.
Do not store any dangerous goods in the safety area of the
rotational vacuum concentrator.
Do not stay in the safety area longer than what is absolutely
necessary for the operation of the rotational vacuum concentrator
Only use accessories that have been approved by the
manufacturer (except 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
6.2.2).
3.7 Safety Devices
3.7.1 Lid Lock Device
The rotational vacuum concentrator 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 rotational vacuum concentrator cannot
be started (see 7.1.4 "Emergency Lid Release").
3.7.1 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 6.3.5.4 "Process & Equipment
Information System" or 7.1.1 "Error Messages").
3.7.2 Power Failure Safety
The unit stores the current process parameters cyclically. In the event
of a power failure, the electromagnetic stop valve will close
automatically, the rotor chamber will be aerated by the aeration valve
and the rotor decelerates brakeless. After the restart of the power
supply, the evaporation process continues with the last stored
parameters.
3.7.3 Ground Wire Check
For the ground wire check, there is an equipotential bonding screw on
the rear panel of the rotational vacuum concentrator. A ground wire
check can be carried out using a suitable measuring instrument.
