12.4 Removal of the splash guard receiver and cap
The splash guard receiver and the splash guard cap can be removed from the bowl (fig. 7.5), centrifugation
area, (fig. 7.5), for cleaning.
Removal of the splash guard receiver and the splash guard cap:
Remove the splash guard cap (fig. 7.5) from the bowl (fig. 7.5)
Carefully flap the inner sealing ring (fig. 7.5) upwards and remove the splash guard receiver (fig. 7.5) out of
the centrifugation area.
Installation of the splash guard receiver and splash guard cap:
At the back of the centrifugation area carefully flap the sealing ring (fig. 7.5,) upwards and push the splash
guard receiver (fig. 7.5) under the sealing ring (fig. 7.5)
The drain hole of the splash guard receiver must be located above the drain hole in the bowl
Carefully flap the sealing ring upwards around the splash guard receiver on the inside and press the splash
guard receiver carefully downwards. The splash guard receiver (fig. 7.5) must be located below the sealing
ring (fig. 7.5).
Place the splash guard cap (fig. 7.5) onto the splash guard receiver in such a way that the inscription "this
side up" can be read, refer to fig. 7.5 (in red)
12.5 Flushing the system with deionized or distilled water
Take off the saline-tube, solution 1, from the physiological saline solution container and dip it into the provided
flask with deionized or distilled water
Start the system-program “flush”
Take off the saline tube from the flask and dip it back into the saline solution container
Open the lid and dry the centrifuging area
Keep the deionized or distilled water in the system until you start with the next wash procedure to
protect the system from crystallized salt crystals.
Take care to rinse the system with the flush-program before starting any other program, otherwise the
probes will be disturbed.
12.6 Cleaning the system with cleaning solution
In a beaker, prepare about 400ml of 0.5% sodium hypochlorite cleaning solution, also prepare deionized or
distilled water in a flask
Take off the saline tube, solution 1 from the physiological saline solution container and dip it into the beaker
with the 0.5% sodium hypochlorite cleaning solution
Start the system-program “flush”
Wait 5 minutes
Take off the saline tube from the beaker and dip it into the flask with deionized or distilled water
Start the system-program “flush”
Open the lid and dry the centrifuging area
Take off the saline tube from the flask and dip it into the saline solution container
Start the system program “flush”
Check the filling volume by doing the procedure “10.2 calibrating the filling volume”
Take off the saline tube from the saline solution container and dip it into the flask with deionized or distilled
water
Start the system program “flush”
Keep the deionized or distilled water in the system until you start with the next wash procedure and take care
to rinse the system with the flush program before starting any other program
