CARE AND MAINTENANCE
4.1 Care
Care of the devices is restricted to the work listed below:
Before cleaning them, disconnect the devices from the mains. Make sure no cleaning fluids
penetrate inside the devices.
The devices are not provided with any particular protection against corrosive, potentially
infectious, toxic or radioactive samples, or against any other samples that may be hazardous
to health. All statutory requirements, in particular the national regulations for accident
prevention, must be complied with when handling such samples.
When removing contamination from the device, comply with the regulations for accident
prevention.
Do not allow any liquids to penetrate inside the device.
Remove dust and visible dirt using a brush, blower brush, cotton bud, lens paper or cotton
cloth.
Remove water-soluble dirt (coffee, cola etc.) by first breathing on it then wiping it with a non-
linting cotton cloth or a moistened cloth. If desired the moistening can be with a mild cleaning
fluid instead of water.
Wipe off heavier deposits of dirt (immersion oils, fingerprints) with a cotton bud or non-linting
cotton cloth using lens cleaning fluid mixture L.
This cleaning mixture consists of 90 vol% gasoline and 10 vol% isopropanol (IPA). The
individual constituents are also known as the following synonyms:
Gasoline:
Surgical spirit, petroleum ether
Isopropanol:
2-propanol,
Di-methyl carbinol,
2-hydroxy propane
All plates on the components and on the table-top power supply unit may be cleaned only
with a dry cotton cloth.
