Place the Kit (Atmospherics) and run some pipes to the place you want to vent the heat. Place a few Pipe Radiators on the pipe, you can use any gas to fill it, but Pollutants X is the best thermal conductor, meaning it transfers heat faster and more efficiently.
Make a return loop on the coolant system back to the coolant waste port for slightly better efficiency.
It will try to draw or expel heat to the coolant mix to make the input match the desired output. A higher difference in the control panel temperature and input temperature makes the system use more power and also works faster. See the diagram for an example
