Proper/designated use
Use the unit only for the application described in the following.
The OXS is a tank system with an integrated diaphragm and a hydraulically
driven degassing and dewatering unit.
The integrated diaphragm prevents direct contact with the ambient air. This
effectively "vacuum-packs" the fluid. The OXS can therefore be used in very
dusty and damp environments.
NOTICE
Impermissible operating media
The unit will be destroyed.
►Use the unit only in conjunction with mineral oils compliant with DIN
51524.
Proper or designated use of the product extends to the following:
•Maintaining adherence to all the instructions contained in the
operation and maintenance manual.
•Performing inspection and maintenance work.
