5 CARE, MAINTENANCE AND SERVICE
5.1 Care
Care of the devices is restricted to the following operations:
The devices are not equipped with special equipment protecting them from corrosive,
potentially infectious, toxic and radioactive or other samples that may be hazardous to health. If
you handle such samples, be sure to observe all legal requirements, in particular the relevant
national accident prevention regulations.
•
Remove contamination in accordance with the national accident prevention regulations.
•
Disconnect the devices from the mains power after use. Protect the devices from dust and moisture by
using a suitable cover (protective device cover).
•
Never expose the devices to inadmissible climate conditions (high humidity and temperature).
Disconnect the devices from the mains power before cleaning. Make sure, that no cleaning
fluids penetrate into the device.
Tenacious impurities on glass surfaces such as fingerprints and traces of grease, are best removed using a
cotton wool bud wound around a round wooden stick and very little distilled water or non-aggressive
solvent:
•
Distilled water: Clean glass surface with the slightly moistened cotton wool bud from the center to the
edge, using circular movements.
•
Cleaning solution for optics, consisting of 15 % isopropanol and 85 % surgical spirit (gasoline): Clean
glass surface by the slightly moistened cotton wool bud from the center to the edge, using circular
movements.
•
Remove dust from optical surfaces using a brush with natural bristles or blow using rubber bellows (air
blower).
•
Clean plastic parts using commercially available cleaning products (no solvents!).
Tenacious impurities can be treated carefully with benzine or white spirit.
•
All labels on the components and on the desktop power unit may only be cleaned using a dry cotton
cloth.
