Mechanical Installation
The wall mounted housing should be installed at an easily accessible place to enable the
reading out of messages at every time and to ensure an easy maintenance.
Please pay attention to the indicated operation temperature for the IMC and build in transmitters
( DB). The IMC should be installed protected against weather conditions and bigger climatic
fluctuations.
In general we do not recommend an installation outside, as in principle measuring accuracy and
lifetime are influenced in a negative way. In case it is however necessary, please contact ExTox
to design a suitable type. For this the following measures are necessary: control unit to be in-
stalled inside, enclosure heating and rain protection cover for housing fans. In addition to this a
protection against driving rain and direct sun, for example in form of a housing, have to be
installed.
The dimensions for assembly and further installation dimensions can be taken from the Technical
Data Sheet ( DB). The wall mounted housing can be opened by means of a usual two cam lock
key.
The IMC itself may not be installed in hazardous areas. The air change via ventilation of the
housing is that designed that in case of a leakage in the internal hosing the measured gas is
always that much diluted that a hazardous gas mixture cannot occur inside the housing. Due to
the rotary speed monitoring of the two fans the function of the so called "inner explosion protec-
tion" is ensured.
