8 Cleaning and maintenance
• Unplug the mains plug of power unit IEX-A01.
• Check, whether the electrostatic earth connection is plugged in correctly and
make sure it is in good working order.
• Clean the balance and the housing, using a slightly moistened cloth.
Simply apply any commercially available cleaning agent available for
domestic use.
• Do not use any agents for cleaning that may scratch the surface
mechanically. Among other things it is covered in a conductive coat that is
important for safe operation.
• The adjustable feet of the platform balance and the shock absorbers
are made of rubber. When they are inside the hazard area, you will
have to use a slightly moistened cloth for cleaning. Moistness
protects against electrostatic charges.
• Make sure that you do not damage the earth contact springs during
cleaning. They serve as a retainer of electrostatic charge on the
weighing pan. They should be approx. 5 mm above the shock
absorbers.
• Do not clean in the presence of explosive gasses.
• The use of concentrated acids, alkaline solutions or alcohols for
cleaning purposes is prohibited.
• The same applies to the use of compressed air and high pressure
cleaning equipment.
