Shut off the cooling water supply during heating. You will save energy and achieve shorter heat-
ing times.

Temperature control unit with batch
2.8.1
Operation as bath thermostat
Note the volume displacement caused by a sample (e.g. Erlenmeyer flask). Place your sample into
the empty bath. Only then fill in a sufficient amount of temperature control medium. Also note that
the level of the temperature control medium drops when you remove the sample. This may cause a
safety shutdown (low level protection) during an enabled thermoregulation. Therefore, switch off
the temperature control unit beforehand.

Preparations for operation
2.9.1
Unscrewing/activating the leveling feet (if any)
The leveling feet are not unscrewed/activated before switching on the temperature control unit
DEATH OR SERIOUS INJURY DUE TO CRUSHING
The parking brakes must be activated at the casters (if any) and/or the leveling feet must be
unscrewed/activated before the temperature control unit is put into operation.
The temperature control unit may move if the parking brakes of the casters (if any) are not
activated and/or the leveling feet are not unscrewed/activated.
Always unscrew/activate the leveling feet before switching on the temperature control unit.
Uneven floors can be compensated by adjusting these leveling feet.
PROCEDURE
Verify that the parking brakes of the casters (if any) have been activated.
Unscrew the leveling feet.
Compensate uneven floors by adjusting these leveling feet, if necessary. Use a spirit level to
horizontally align the temperature control unit.
Tighten the lock screws on the leveling feet after aligning the temperature control unit. This
prevents the leveling feet from changing their height during operation.
2.9.2
Externally closed and externally open applications
Using a pre-assembled pump adapter that is also available as an accessory, you can also control the
temperature of an external application (e.g. reactor or open bath vessel). Externally open applica-
tions can run without interference only in conjunction with a DS level stabilizer (accessory). The DS
level stabilizer compensates the differences in the pump (pressure capacity and throughput). If not
already attached, please install the pump adapter. In an externally open application, please also
install the DS level stabilizer on the externally open bath and observe on page 55 the section
and venting the bath thermostat and the externally closed application«
as well as the operation
manual of the DS level stabilizer.
