CR 4200 Overview
1Overview
The thermoreactor CR 4200 is a dry temperature control device for
laboratory use. It facilitates and secures the digestion using reaction
cells.
The thermoreactor has 8 fixed temperature programs.
1: 148 °C for 120 minutes
2: 120 °C for 30 minutes
3: 120 °C for 60 minutes
4: 120 °C for 120 minutes
5: 100 °C for 60 minutes
6: 148 °C for 20 minutes
7: 150 °C for 120 minutes
8: 100 °C for 30 minutes
8 more temperature programs can be set up freely. The reaction
temperature can be adjusted from room temperature to 170 °C, the
heating time from 0 to 180 min.
The thermoreactor takes 24 reaction cells with an outer diameter of
16 mm.
The thermoreactor CR 4200 has two independent thermoblocks and
thus enables two temperature programs to run simultaneously.

CR 4200 Safety
2 Safety
This operating manual contains basic instructions that you must follow
during the commissioning, operation and maintenance of the
thermoreactor. Consequently, all responsible personnel must read this
operating manual before working with the thermoreactor. The operating
manual must always be available within the vicinity of the
thermoreactor.
Target group The thermoreactor was developed for use in the laboratory. Thus, we
assume that, as a result of their professional training and experience,
the operators will know the necessary safety precautions to take when
handling chemicals.
General safety
instructions
Other labels
The individual chapters of this operating manual use the following
safety labels to indicate different levels of danger:

Safety CR 4200
2.1 Authorized use
The authorized use of the thermoreactor is exclusively the heating of
samples in cells in a laboratory. The technical specifications as given
in chapter 8 T
ECHNICAL DATA must be observed. Only the operation and
running of the measuring instrument according to the instructions given
in this operating manual is authorized. Any other use is considered
unauthorized.
2.2 General safety instructions
This thermoreactor is constructed and tested in compliance with the EN
61010 safety regulations for electronic measuring instruments. It left
the factory in a safe and secure technical condition.
Function and operating
safety
The smooth functioning and operational safety of the thermoreactor
can only be guaranteed if the generally applicable safety measures and
the specific safety instructions in this operating manual are followed
during operation.
The smooth functioning and operational safety of the thermoreactor
can only be guaranteed under the environmental and electrical
operating conditions that are specified in chapter 8 T
ECHNICAL DATA.
If the thermoreactor was transported from a cold environment to a
warm environment, the formation of condensate can impair the
functioning of the measuring system. In this event, wait until the
temperature of the thermoreactor reaches room temperature before
putting the thermoreactor back into operation.
Caution
The thermoreactor is only allowed to be opened by personnel authorized by.

CR 4200 Safety
Safe operation If safe operation is no longer possible, the thermoreactor must be taken
out of service and secured against inadvertent operation. Safe
operation is no longer possible if the thermoreactor
has been damaged in transport
has been stored under adverse conditions for a lengthy period of
time
is visibly damaged
no longer operates as described in this manual.
If you are in any doubt, please contact the supplier of the
thermoreactor.
Obligations of the
purchaser
The purchaser of this thermoreactor must ensure that the following
laws and guidelines are observed when using dangerous substances:
EEC directives for protective labor legislation
National protective labor legislation
Safety regulations
Safety datasheets of the chemical manufacturers.

Warning
Always keep the original packing including the inner packing. If
you have to transport the instrument, the packing protects the instrument optimally from hard shocks.
The original packing is also required for the appropriate return
transport of the instrument if it has to be repaired.
Please note that the warranty does not cover damage caused by
inappropriate transport.

3.2 Initial commissioning
Note
The thermoreactor works at an ambient temperature of +5 °C to
+40 °C. When the thermoreactor was transported from a cold
environment to a warm environment, condensate may occur and cause
a malfunction. Wait until the thermoreactor has adjusted to the new
environmental conditions before putting it into operation again (see
also chapter 8 T
ECHNICAL DATA).
Setting up the
thermoreactor
Adjusting the mains
voltage
1 Place the thermoreactor firmly onto a heat-resistant
underground.
2 Make sure that there is enough space between the
thermoreactor and other instruments or devices that are heatsensitive.

3 Check whether the arrow on the housing points to the mains
voltage (115 or 230 V) given on the fuse holder (3) that is
provided by the mains.
4 If the wrong mains voltage is set, perform steps 5 to 7.
5 Pull out the fuse holder (3).
6 Turn the fuse holder (3) so that the arrow on the housing points
to the mains voltage (115 or 230 V) provided by the mains.
7 Push the fuse holder (3) in completely.
