Functions
Pre-Infusion and Brew are two phases of the coffee extraction cycle. Pre-Infusion introduces
hot water to the coffee puck at a low pressure to saturate the coffee and let it bloom. Once the
coffee has had a chance to bloom the Brew cycle is started. Hot water under pressure is forced
through the coffee to produce espresso. Mavam gives the barista complete control over the
time, flow, pressure, and temperature the coffee is extracted at.
Pre-Infusion
Low water flow restricted to 2 bar 30 psi. This is can be run manually or set to a desired time in
Auto mode. The Left paddle turns on and off the Pre-Infusion phase of the brew cycle. This is
also used to ramp down or finish the shot in low flow mode.
Maximum time allowed is 360 seconds (6 minutes). Pre-Infusion will shut off after this time.
