Detailed information about the compatibility of cleaning agents can be found in the Reference
Manual (RM) of your XPR balance.

6.1.1 Cleaning the housing

The housing material of the dosing module and the dosing lift 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 SOP (Standard Operating Procedure).
The dosing module is in its uppermost position.
1 Remove the sealing insert (1).
2 Clean the sealing insert with a wet cloth and a mild
cleaning agent or dispose of it. Do not wash the sealing
insert in the dishwasher.
3 Install the cleaned sealing insert or a new one.
