- Page 16 Brew Gauge: The brew gauge reflects the pressure in the brewing system. On a standard Cyncra, there is one gauge for the entire brewing system; on a Hydra, each brew tank has its own brew gauge. The gauge normally moves between 3-5 bar (resting pressure) to 9 bar (brewing pressure) and up to 12 bar (expansion pressure) at which point the expansion valve opens and releases the excess pressure.
- Page 17 Water Inlet Components (cont.): Cold Water Valve: Synesso has 2 valves which provide water to the Americano (tea) spout: the hot water valve and this cold water valve. The cold water input allows the user to moderate the temperature at the spout to make drinks appropriate temperatures for their customers.
