The alignment of the cutting ring must be taken into account when installing
the cutting ring.
The allowed assembly tolerance is +/- 3 degrees deviation from the horizontal
alignment.
When installing, make sure that there is sufficient clearance around the lower
screw plug and the measuring connection. The two connections must be freely
accessible for maintenance purposes
Leakage from the siphon blocks can negatively affect crankcase monitoring.
To ensure leak-tightness at the siphon block, you must observe the alignment
when installing the cutting ring.
The oil return hole of the connection screw must be closed by the tip of the
filling pipe. Otherwise, the lubrication oil that is introduced will run into the
crankcase and not into the ducts of the siphon block.
