16.3.3 CLEANING THE PUMP HEAD

When changing flexible tube or other parts, inspect all parts for dirt before assembling the
pump head and clean them if necessary.

As far as possible clean the parts with a dry cloth. Solvents should not be used as they can
attack the plastics and synthetic rubber parts. If a compressed air line is available, blow the
parts out with it.
C A R E !
Aggressive sample is possible!
Wear protective glasses and proper protective clothing
during disassembly, repair or cleaning!

17.1 CHANGING THE SET VALUE
To change the set value the P-key has to be pushed < 2 sec. The company fixed value of 5°C
appears. With the two arrow keys the value can be changed. This value should not be adjusted lower
than +1°C, because otherwise the heat exchanger will freeze up. Is the value adjusted higher than the
ambient temperature the cooler will not work.
17.2 CHANGING THE TEMPERATURE ALARM WINDOW
The exact description of changing the temperature alarm window can be found in the manual of the
temperature controller.
