My bottle has 5kg CO2, and it?s too tall to be installed close or under de 
tank. Thus is it placed in the garage. I installed 60 feet of plastic tubing 
inside the conducts of the electric installation, so nothing is could be 
seen. The plastic tube is the one used for pneumatic automation, of standard 
4mm diameter.

The bottle has a regular CO2 regulator as first stage (2 Kg), and a second 
regulator for secondary stage, which feed the mentioned plastic tube 
(stables 0.6 Kg/cm2). The late one is a standard industrial compressed air 
device. I installed when I notice that the pressure of the first stage 
varied with CO2 level inside the bottle.

Between stage one and two is a relief valve, just in case of first stage 
malfunction.
