2.2. Instructions for assembly and operation
Note for recording the filling amount of tanks:
When recording the filling amount, check if the entire tank content is available — or if
a residual part has to remain in the tank due to its design. For example, in oil tanks, the
intake pipe does not typically reach the ground to prevent draining sediments. In such
cases, approx. 5—10% of the tank content can be unavailable.
