The Tip clean and Tip rinse solutions are needed to clean and rinse the probes
after measurement, before the system stops and should be replaced (if not used
up) all three months.
The Cuvette Clean is used during run for tip pre/post wash- and cuvette post
wash and should be replaced (if not used up) all three months.
The
Diluent
is used for sample/calibrator pre- and post dilution and for blank
measurements and should be replaced (if not used up) once a month.
1. Check the system wash solution behind the front door, if necessary prepare
new, for details refer to the IFU of Wash Add Ref 18971. After replacement
flush the system. Don’t top up to avoid contamination and bacterial grow.
2. Check the Tip Clean and - Rinse (Ref 16663/25) in the reagent tray, replace
if necessary.
3. Check the Cuvette Clean (Ref. 16663/20) in the reagent tray, replace if nec-
essary.

8.2.3 EMPTY WASTE BOTTLE
The waste bottle is placed on a scale and if the bottle is full, the system will show
an alarm. Open the front door, empty the waste bottle and put it back into the
system.
8.2.4 HYDRAULIC TESTING – SYSTEM FLUSH
System flush is required at least once per day and can be set to be automatically
performed during analyzer start up at the beginning of the day. In case that
analyzer has stayed operational and has not been switched off then the system
flush warning will come up at the specified time. Air gaps and bubbles should
be flushed, if present, particularly after the filling operation of system bottles or
after cleaning the probes.
1. Open the Maintenance scheduler status screen and press
Perform
behind
the System Flush function.
2. During process look for:
- Presence of bubbles or air gaps in system
- Leakage in peristaltic pump
- Constant and uniform flow from probe tip
- No droplets hanging on probe tip
- In case new bubbles generate in the process, Refer to chapter 9 “Trouble-
shooting”.
3. The scheduler will be updated automatically.
