Different set ups for different cassettes. The older c200 cassette is connected where the pressure release valve is. You remove that and fit the coupler provided. Does the same job, just connected to a different part of the cassette.
Ok . So I have the C200. I’m guessing then I couldn’t opt to install the vent at the spout because of the pressure differential, it would be like pulling on a vacuum? That’s fine in principal if I’m venting through the pressure valve, but if I want to use a second cassette, is that awkward? If venting at the spout, well it’s easy to use the same drilled out cap on both cassettes.
