    switch behind drip tray in expobar Minora II

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    notice for sometime there is a switch behind the drip tray and I can turn it using a flathead screwdriver, can someone tell me what is that switch for, no description from the brochure, sorry I dont have the instruction book anymore.

    thanks.

    Normally I dont respond to forum posts unless Im certain of the answer. (No one likes people talking out their other end about stuff they dont know) But in the absence of someone with a definitive answer. Im gonna say this is to adjust the OPV (over pressure valve) which controls the brew pressure.

    Im planning on buying a Minore shortly and hence have come across this in my research.

    thanks Acog, I wonder if I turn it 360 degree clockwise what would that do to my coffee.
