11. DEVICE CLEANING
Prior to cleaning it is necessary to
disconnect the device from the mains!
Remove the plug from the outlet,
disconnect all cables.
Do not use aggressive cleaning
agents (e.g. solvents, chlorine
preparations, corrosive chemicals,
bleach).
• GLASS PANES AND COMPONENTS can be cleaned using window cleaner.
• WEIGHING PANS AND STAINLESS STEEL OR ALUMINIUM COMPONENTS can be cleaned using a cloth slightly
soaked in a solution of water and gentle cleanser (e.g. soap or dishwashing liquid).
• OPERATION PANEL AND HOUSING can be cleaned using a cloth slightly soaked in a solution of water and gentle
cleanser (e.g. soap or dishwashing liquid).
• Dry sample leftovers can be removed using either brush or handheld vacuum cleaner.
•Clean components can be dried using soft cloth or dust-free paper towel, with this the remaining moist will be absorbed.
• Install all the components providing they are completely dry.
Use soft cloth made of either natural or
synthetic fiber exclusively. Avoid using
cloth made of stiff/hard fabric, this
could cause scratches on the surface!
Apply the cleanser onto the cloth. Mind
not to apply the cleanser directly onto
the device!
Make sure that neither dust nor
liquid gets inside the weighing
system (device inside).
11.1. Guidelines and precautions
11.2. Cleaning instructions
Shall it be necessary to disassemble the weighing chamber,
follow the description provided in section 11.3.
Neither use substances of sharp
structure nor intended for
scrubbing.
