16.3.4 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.
Caution
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-button has to be pushed in for < 2 sec. The default value of 5 °C [41 °F]
appears. With the two arrow buttons the value can be changed. This value should not be adjusted lower
than +1 °C [33.8 °F], because otherwise the heat exchanger will freeze up. Is the value adjusted higher
than the ambient temperature the cooler will not work.
