7.15.3 Cleaning (F3 – special functions)
To perform the cleaning and the drying cycle, you will need a Sartocheck® cleaning
kit (art. n° 16288---CK).
The cleaning menu allows you to flush all internal pneumatic parts completely,
from the valves to the internal reference tank.
The cleaning procedure is divided into 5 interactive steps. Sartocheck
®
3 plus will
guide you through each individual step. A diagram will show you which connections
are to be connected with the flushing tubing during the ongoing step.
After you have installed all the connections according to instructions, press the
start button. Sartocheck
®
3 plus then automatically carries out the current cleaning
step. At the end of cleaning, the drying menu is activated automatically. We recom-
mend that you also carrying out a drying routine after every cleaning. This is done
to ensure that no detergent solution remains in the pneumatic block.
If drying is not performed after cleaning, a message stating that the drying cycle
has been cancelled will display every time a test is started. Once the drying cycle has
been completed, this message will no longer display.
Description of the connections:
a:
IN – Inlet pressure tubing
Connect inlet pressure tubing
b:

Connect this outlet as defined for each individual step
d:
Venting 1
Connect this outlet as defined for each individual step
e:

Cleaning fluid
The cleaning fluid we recommend:
Water (cold, warm or hot; never use warm or hot water for protein contamination!)
Buffer solutions, e.g. 0.9 % NaCl Solution
Sodium hydroxide solution, max. 1 M
In step 5, clean the entire pneumatic components, i.e. the pneumatic block and
the internal reference tank are flushed with water. This is done to ensure that no
detergents remain in Sartocheck
®
3 plus.
If you have not installed the connections in accordance with the diagram and the
procedure has already started, we recommend that you cancel cleaning and restart.
The pneumatic components can be damaged or their function impaired by improper
connection. Improperly connected tubing can also impair the effectiveness of the
cleaning procedure. Therefore cleaning should be restarted.
