d) Finally, it is recommended that you use the bellows once again, thus removing any remains of paper or cotton.
5.3.3. Cleaning the dispensing system
It is a good idea to recommend to the user that he configures the analyzer to automatically wash the dispensing system
with washing solution at the start and end of each working day to ensure that it is completely free from air bubbles and
is perfectly clean. With the initial wash, the system is ready for working in optimum conditions during the entire working
day, offering maximum performance. With the final wash, the analyzer cleans the needle at the end of the working day,
keeping it in optimum condition for future working days. Additional washing of the dispensing system can be performed
using the Dispensing system wash utility of the user program. The analyzer must be in standby mode.
The user himself should clean and check the state of the distilled water container filters at least once every 3 months.
The service operations should also check the state of these filters.
If the needle is obstructed by solid residue, it must be removed and cleaned using the metal cleaning rod supplied with
the analyzer. For this, the Remove the dispensing needle utility should be used. It is also recommendable to clean the
outside surface of the needle with a piece of cotton or a soft cloth dampened with alcohol. The needle must be replaced
if it is noticeably deteriorated.
5.3.4. General cleaning of the interior of the apparatus
It is important for the interior of the instrument to be free from dust at all times in order to preserve the correct functioning
of the different components. For this, remove the front housing of the analyzer and carefully clean the dust inside the
instrument.
