6.1 Service
6.1.1 Device
Avoid the drying of saline, aqueous solutions as well as the long-term exposure of acids and
alkali on the material (aluminum).
Avoid the use of aggressive chemicals, including strong and weak alkali, strong acids,
solutions with mercury, copper and other heavy metal ions, halogenated hydrocarbons,
concentrated saline solutions and phenol.
For the frequent evaporation of corrosive liquids, apply a thin coating of pivot grease to the
rotor and rotor chamber (order no. Int.: 5810 350.050 / North America: 022634330).
6.1.2 Pump
The chemical-resistant pump of the complete system does not need to be maintained by the user.
However, the valves and diaphragms are subject to natural wear and tear.
Remove the condensate regularly from the pump and the hose system by pressing the
mode/vent key.
This will prolong the service life of the consumables.
Observe any changes in the time required for your application. If you notice any deterioration,
at the latest, have the valves and diaphragms checked by the authorized service.
6.2 Prepare for cleaning/disinfecting
Clean the accessible surfaces of the device and the accessories at least once a month and if

Please also follow the instructions on decontamination (see Decontamination before shipping on
page 33) if you send the device to authorized Technical Service for repair.
