7. Cleaning and Maintenance
7.1 Important notes about cleaning this instrument
Warning
• The instrument should always be cleaned after the end of work, but BEFORE the instrument is
shut down. An exception from this is cleaning the interior (
→
P. 107 – 7.2.4 Interior cleaning) . We
recommend cleaning while the instrument is shut down.
• The regular maintenance intervals must be observed.
• When using cleaners, please comply with the safety instructions of the manufacturer and the
laboratory safety regulations.
• Proceed carefully and wear suitable protective clothing when cleaning the instrument (lab coat, cut-
resistant gloves and safety goggles).
• Never use solvents (such as alcohol, acetone, xylene, toluene etc.) or cleaning agents containing
solvents to clean the exterior of the instrument.
• Prevent liquids from entering the interior of the instrument or electrical contacts while the
instrument is being cleaned or during operation.
• Solvent vapors can develop if solvents are left in the instrument after shutting it down. There is a
risk of fire or poisoning if the instrument is not operated under a fume hood!
• Dispose of used reagents while observing applicable local regulations and the disposal regulations
of your company/lab.
• Shutting down the instrument for longer breaks in work and switch it off at the end of the workday
( → P. 76 – 6.2 Switching on and shutting down the instrument) .
• Immediately use a lint-free cloth to wipe off mounting medium that drips onto/into the instrument
(e.g. during priming or exchanging a mounting medium bottle).
• Make sure that significant amounts of solvent are not spilled in the instrument (danger for the
electronics!). If solvent has been spilled, immediately remove the liquid with an absorbent cloth.
• To prevent damage, never leave plastic accessories immersed in solvent or water for a prolonged
time (e.g. overnight).
• Never clean plastic reagent vessels at temperatures higher than 65 °C since this can deform
reagent vessels!
7.2 Description of cleaning individual instrument components and areas
7.2.1 Exterior surfaces, varnished surfaces, instrument hood
» The surfaces (hood and housing) can be cleaned with a mild, pH-neutral, commercially available
cleaning agent. After cleaning the surfaces, wipe them off with a cloth moistened with water.
Warning
Varnished instrument surfaces and plastic surfaces (e.g. an instrument hood) may not be cleaned
with solvents like acetone, xylene, toluene, xylene substitutes, alcohol, alcohol mixtures and abrasives!
In case of long-term exposure, the surfaces and instrument hood are only conditionally resistant to
solvents.
