Operation
Controls
Power Control
Power Switch: Power for the entire machine is controlled by the switch on the front left side
of the face. Caution: while this removes power from the unit line power is still supplied to the
machine.
Temperature Controller: This is the main controller for temperature of all elements, steam
pressure, fill, and internal sensing referred to as “BCU (Boiler Unit Controller)” for the
remainder of the manual. Note: For operation of the BCU refer to the manual titled “BOILER
UNIT CONTROLLER USE AND SETUP”.
User Interface
There are two main components of the User Interface used for operation, actuators, and UI
display. Display is discussed in detail in the section “UI DISPLAY”.
Actuators
Actuator Placement c on User Interface
UI Actuators control all the functions of the UI. They consist of an actuator, (the part you
push), and an illuminated ring that indicates mode of operation.

General
Preinfusion and Brew controls are activated by paddles wrapped around the group heads. The
Steam is activated by slap / push in style switches located on the upper side panels of the
machine. The hot water is activated via a piezo touch activated switch. These actuators control
all functions of the machine (Pre-Infusion, Brew, Steam, and Water) the display screen will
show all functions of the machine. S for Steam, W for Hot Water Tap, Pre Infusion turns on the
left display timer and Brew or full pressure turns on the right display timer.
There is a short delay, (¼ second), required between pushes. Pushing the actuator faster than
this will not register a new push.
The Mach 2 Uses a screen saver to protect the OLED display screen. In this state the MAVAM
coffee drop will appear. Press the group activation levers to open the home page.
Each actuator has two uses, regular operation, and menu (setting options for that group). Uses
of the actuator are detailed in the “Functions” section.
Startup
On power up the group OLED will display the version number in the upper data window. Please
note this information for reference later on. Some operations are different depending on
software version. These are noted in instructions as “After, (or before) Version X.X…” for
example.

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.
Menu: Selects one of two options or increments a setting (counts up).
Can also trigger Auto 1 when in Auto Mode
NOTE: Holding down paddle actuator will change in increments of 10s after counting three.
Brew
Turns on Brew valve and Pump Motor. In manual mode once desired preinfusion is reached
pressing the brew actuator turns on Full pressure or the pump of the specific group. The pump
can be adjusted to any extraction pressure from 3-12 Bars
Maximum time allowed is 120 seconds (2 minutes). Brew will shut off after this time.
Activates Auto 2 in Auto mode
Menu: Selects one of two options or decrements a setting (counts down).
NOTE: Holding down paddle actuator will in decrement in 10s after counting three.

minutes). Steam will shut off after this time.
