To remove them and ret them, the corresponding instructions given in the Maintenance chapter must be carefully
followed. Avoid touching the useful area of these elements with ngers. The lters and the photodiode must be held
by the sides. Do not touch the lamp bulb. To handle the lamp, use the wrapping, cutting it at the terminal end and
squeezing it until they come out. To clean the optical components, bear in mind the following:
a) Remove the dust on the surface of the component with the bellows. This will avoid scratching by particles when
cleaning with paper.
b) Carefully clean the surface of the component with the cleaning paper.
c) If the dirt is persistent or greasy, clean the component with the paper moistened with the alcohol and ether solution.
Then dry with dry paper. To clean the lters or the window of the photodiode, use the cotton wool buds with the
paper in difcult and delicate areas.
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 congures 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 nal 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 lters at least once every 3 months.
The service operations should also check the state of these lters.
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 noticeably deteriorates.
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 functio-
ning of the different elements. For this, remove the front housing of the analyzer and electronics cover and carefully
clean the dust inside the instrument.
