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.

Safety CR 2200
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.
8
ba76119e01 08/2012

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.

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 (2) 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 (2).
6 Turn the fuse holder (2) 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 (2) in completely.

4 Basic principles of operation
This chapter provides you with basic information on how to operate the
thermoreactor.
4.1 Operating and display elements
Using the six keys of the keypad (see section 4.1.1) you control the
thermoreactor.
Temperature values, available temperature programs or settings can
be viewed in the display (see section 4.1.2).
The control lamps above the operating panel are assigned to the
thermoblock. Their color (red or green) and their state (flashing or
illuminated) show the current operating state of the thermoreactor (see
section 4.1.3).

The thermoreactor is in the program selection mode.
As soon as the thermoblock has cooled down to under 50°C, the
control lamps switch themselves off.
If the start of the timer for the reaction time has been set to manual in
the SETUP menu (START TIMER:MAN. see section 5.4.2), an S is
displayed in front of the nominal reaction time. With this setting the
thermoreactor controls the temperature until the timer for the reaction
time is started by pressing g.
4 Start the timer for the reaction time with g. The S in front of
the reaction time disappears.
20
The reaction temperature is kept constant during the reaction time.

If liquid penetrated a thermoblock (e.g. from a cell), clean the
thermoblock as follows:
Warning
Cells can contain poisonous or corrosive substances. If the content has been set free observe the danger notes on the cell. If necessary take the corresponding protective measures (protective
goggles, protective gloves etc.).
Warning
The thermoblock can become very hot (150 °C). There is danger
of burning when the thermoblock is heated up.
