6.1 Cleaning
WARNING
Risk of electric shock
1 The power cable must be disconnected prior to cleaning and maintenance.
2 Use only the power cable from METTLER TOLEDO, if it needs replacing.
3 Ensure that no liquid comes into contact with the terminal or the AC adapter.
4 Never open the instrument housing, terminal, or AC adapter – they contain no
components that can be cleaned, repaired, or replaced by the user.
NOTICE
Damage to the instrument due to inappropriate cleaning methods
The instrument can be damaged by certain cleaning agents, solvents, or abrasives. If liquids
enter the housing, they can damage the instrument.
1 Only use a wet cloth with water and a mild detergent to clean the instrument or terminal.
2 Wipe off any spills immediately.
3 Make sure that no liquid penetrates the instrument.
The appropriate maintenance interval depends on your standard operating procedure (SOP).
6.1.1 Cleaning the housing
The housing of the dosing module, dosing lift, and liquid module is the same as the one of the balance. All
surfaces can therefore be cleaned with a commercially available, mild cleaning agent.
6.1.2 Cleaning the sealing insert
The sealing insert is located right under the tip of the dosing head. It is therefore the element that is the most
likely to be contaminated by the substances dosed with the dosing module. Clean or replace the sealing insert
regularly, depending on the substances used and your Standard Operating Procedures (SOP).

§
