Testing
The cleaning solution is subjected to a test by conductivity measurement.
The conductivity measuring instrument and the conductivity cell must be calibrated or
checked in accordance with the operating manual of the measuring instrument if necessary.
The following settings must be made on the conductivity measuring instrument:
•
T
Ref
= 25 °C
•
Temperature compensation "nLF"
•
Cell constant in accordance with conductivity cell
If the measured conductivity is in the range of 275 mS/cm ± 20 mS/cm, the cleaning solution
has been properly prepared.
Using the test solution:
Only if the above criteria are fulfilled may the prepared cleaning solution be re-utilized for
production. Otherwise this formulation must be discarded.
Filling
After passing the test, at least 1000 mL of the cleaning solution is poured into the approved
containers and sealed tight with the associated closure (containers as per Chapter 5.1).
The containers are provided with the corresponding labels (see Chapter 5.2)
Shelf life
A shelf life as per Table 4-2 can be warranted for the cleaning solution prepared in this way.
It is printed with the label (see Chapter 5.2) on the containers in MM.YY format.

Storage:
A shelf life for the cleaning solution as of production according to Table 4-2 is specified, from
which the shelf life data on the label of the respective container is derived.
For storage prior to use (transport, distribution center), a storage temperature of +5 °C…25
°C is recommended. Brief heating during this time to 35 °C is not a problem. In the worst
case, irreversible damage from precipitates or even frost damage can occur below 5 °C.
For subsequent use, depending on the weather, temperatures of +15 °C…+45 °C are
obtained in the P 700 IQ which is why the labeled shelf life date continues to be valid without
restriction.
Storage times must be limited to max. 6 months in order to safeguard corresponding usability
for the user.
Disposal
