So here the Mach I as it was originally sold by nVentiv:



Let’s start by removing all the parts we no longer need, like the old evaporator which I can now decommission. The preinstalled insulation is about 3cm thick – since we’ll upgrade the performance of the unit it might not be enough so I decided to remove it and replace it with thicker insulation to prevent condensation.



I removed all the insulation and removed the standard flexible hose too.



Then the search for the temperature sensor begins, the sensor is deeply buried in the PU foam and glued with some sort of thermal compound to the evaporator.



Digging deeper I found the heatingwire and the thermalpad in the housing.



The search is over, the temperature sensor can now safely be removed




With the temperature sensor tucked away the unit is ready to be serviced ->
