Posted Thu Jun 1, 2006, 9:30am Subject: Re: How to adjust the brew pressure of a Giotto Premium?
i think i found my answer: # If you have a pressure sensor panel mounted, use it while running the pump with a blind filter to make the adjustment. If you have a pressure sensing PF, use it while adjusting (it blocks the pumpflow). Now here's the new one, you can approximately set these things without a pressure guage. Vibe pumps drain 2 to 2.5 ounces of water in 25 seconds when they are at 8.5 to 9.5 bar. So put in a blind filter, use a measuring cup to catch the run off back to the tank, and adjust it to get that flow rate (wait for the pressure to max before measuring, you'll hear this in the pump going quiet as the flow stops, it'll take up to 10 seconds for preinfusing ones).
