Accumulation of dangerous gas concentration at the oil mist detector, when
mounted on dual-fuel or gas engines
There is a risk of serious injury, including death, from hazardous accumulation of gas
concentrations in the oil mist detector as a result of incorrect assembly or installation.
The following instructions must therefore be observed, in particular when installing
VN2020 EX:
The oil mist detector must not be installed in a recess that could allow gas to
accumulate!

Impairment of function and operation of the device
The oil mist detector must not be painted, varnished or otherwise altered.
Risk of injury from overhead loads
A suitable means of transport must be used for assembly and for transport to
the assembly site. The measuring head can be attached to the crane using the
lifting eye nut on the protective cover. Suitable lifting equipment must be used
for transport.
Do not step into the area of rotation or under the load.
Carefully secure the load before assembly.
Use personal protective equipment.
Section 2.4 Basic safety instructions
As shown in the figure below, the oil mist detector with protective cover (1) can
alternatively be attached directly to the engine wall via four through-holes with 9 mm
diameter or to a bracket with M8 nuts (2) prepared in advance by the customer,
provided that the engine peripherals allow for this.
The recommended side for mounting on the engine is opposite to the side of
the explosion protection valves.
