Mavam User Manual V2.0 Page 7 of 24

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.
Mavam User Manual V2.0 Page 8 of 24

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.
Mavam User Manual V2.0 Page 9 of 24

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.
Steam:
Regular: Turns on and off the Steam Wand. Maximum time allowed is 120 seconds (2
minutes). Steam will shut off after this time.
Menu: Used as Enter key.
Hot Water
Regular: Turns on and off the Hot Water Jet. Maximum time allowed is 5 sec. Hot Water will
shut off after this time.
Menu: Used as alternate Enter key in three group machines.

Group Head Cleaning
Cleaning is performed everyday. The machine comes with a 3mm wrench. Remove the screen
and diffuser plate with the 3mm wrench and clean with a dry towel.
Reinsert diffusers and screen. Making sure the flat side of the diffuser mounts to the flat side of
the group head.
Find the Blank / Backflush disk that can with the machine. Insert this into the portafilter. Add a
teaspoon of espresso machine cleaner to the backflush cup.
Insert the portafilter with the cleaner into the group head. Each group head must be cleaned
separately. If you choose to do this manually you should run the group 10 times on full pressure
or right button for 2-3 seconds then shutting off. The blank disk will force the cleaner through
the 3 way valve cleaning any leftover coffee in the system. After 10 cycles remove the
portafilter clean out any extra cleaner and perform the same task with just water. This will
remove any left over build up or cleaner inside the valve. Failure to do this can lead to cleaner
stuck inside the valve possible no water out of the group.
We do have an automatic function that will do the 10 cycles for you. Please see below for
instructions.
This is a special function usually performed at the end of the day. The clean cycle will run ten
cycles of five seconds Brew phase and five seconds off. The UI display will show “AUTO CYCLE”
in the top data window with the total cycles on the right of the bottom data window and cycles
completed in the left of the bottom data window. After each cycle the top data window will
display “CYCLES TOTAL” and a total of completed cycles. The following steps describe how to
access this function
1. Enter Menu Mode
2. Using the Paddle actuators, and versions below 3.0, push and hold BOTH the
Pre-Infusion and Brew actuators down until “HLD FOR MENU” shows in the top data
display. Continue holding until “CLEAN? NO” is shown in the top data display.
3. When “CLEAN? NO” is shown use the Pre-Infusion actuator to change to “CLEAN? YES”.
Press the Steam or Water actuator to start the clean cycle. If you do not want to
perform the clean function leave at “NO” and press the Steam or Water actuator to
move to the next menu function. Pressing the Brew actuator will change “YES” to “NO”.
4. Pressing either Pre-Infusion or Brew actuator at any time will cancel the clean cycle.
5. When completed, or stopped, the UI will return to Idle mode.

Manual and Automatic Modes
There are three modes used for the brew cycle, Manual, Timed Automatic and Flow meter
Automatic . Current mode is shown in the upper left corner of the display in the upper data
window. “MAN” = Manual, “AUTO” = Automatic.
Note: In adherence to our philosophy of  total user control  you may change the mode “on the
fly” for each shot if desired. For example, if in Automatic, you may want to pull a different shot.
You can change to Manual when starting the shot and have full control of shot.
Manual Mode
This mode gives the barista complete control over the brew cycle. Once a portafilter is inserted
and ready for use the user may initiate the brew cycle by starting Pre-Infusion or go directly to
Brew. With this full control you can run the machine anyway you like. Long preinfusion, full
pressure to low pressure. Just full pressure. Just low pressure.Low then full pressure etc.
For example: User starts the Pre-Infusion phase and after the desired time has elapsed starts
the Brew phase. Pressing the Brew actuator will finish the cycle, pressing the Pre-Infusion
actuator will change the brew cycle to the low pressure Pre-Infusion phase.
Note: When Brew phase is started the elapsed time will continue to count up in the Brew phase
window of the display.
Automatic Mode
There are two ways to control the brew cycle automatically. There is no one correct way to
control a brew cycle. We offer the user two methods so you can determine which one suits
your preferred method.
1. TIME MODE “ChronoMass”: In this mode the brew cycle, pre-infusion and brew, is
controlled using time. The pre-infusion and brew phase are controlled by the user set
times.
2. FLOW MODE: In this mode the brew cycle is controlled by a flow meter, precisely
measuring the mass of water being sent through the coffee. The user enters the “pulse
count” in the menu to determine the precise amount of water to use. Pre-infusion is
still controlled using time in flow mode.
Mavam User Manual V2.0 Page 13 of 24

Using Time or Flow mode is determined in the menu. When selecting Brew Time if you want to
use Flow mode you must set Brew Time to ZERO (0). If set to anything else the setting for Flow
mode will be bypassed.
Automatic settings are shown in the lower data window when idle, A1 and A2. Settings are
shown as three numbers separated by a forward slash “A1:20/30/0 A2:15/0/300”. The first
number is the Pre-Infusion time, the second is Brew time and the third is pulses. Pressing the
Pre-Infusion actuator will start A1, pressing the Brew actuator will start A2 (if in Automatic
mode)  . When started the cycle will run for the pre-set time and stop. The program will be
shown in the upper data window when running, “AUTO:1”, if running A1, “AUTO:2”, if running
A2. The cycle may be stopped anytime by pressing the current phase actuator. For example, if
in Pre-Infusion phase, pressing the Pre-Infusion actuator will cancel the cycle.

USER INTERFACE MENU INSTRUCTIONS
Menu Overview
Menu functions allow the user to set or change the operating parameters of the User Interface.
Features available in the menu are listed in order with the Parameter  in italics and options
available in parenthesis (). Default option shown in brackets [].
1. CLEAN?  [NO], (YES) Selects auto clean cycle if yes.
2. [CELSIUS  ], (FAHRENHEIT  ) Selects temperature unit.
3. OFFSET  [0.0] Sets a hardware offset for the temperature display. NOTE:  only set this if
you are sure you know the the calibrated temperature of the group. This is set at the
factory and normally does not need to be changed.
4. [MANUAL  ], (AUTOMATIC  ) Changes mode between Manual and Automatic.
5. AUTO PI  NO:1 [0], (0 to 360) Sets the Pre-Infusion time for Automatic one.
6. AUTO BR  NO:1 [0], (0 to 120) Sets the Brew time for Automatic one. NOTE Set to ZERO

7. FLOW: Select one of the options, ZERO, LAST, or HOLD
7.1. ZERO: Sets the flow count to zero.
7.2. LAST: Sets the flow count to the last brew cycle count. This is very useful to “dial
in” a setting. For example, use manual mode to pull shots until you get the
settings you want. Once a good shot is pulled enter the menu and select this to
set the flow count to the last shot you pulled. You can fine tune this in the next
step.
7.3. HOLD: This enters the setting from the one in memory.
8. SET FLOW: Use pre-infusion and brew paddles to change the flow count up or down to
fine tune it.
9. AUTO PI  NO:2 [0], (0 to 360) Sets the Pre-Infusion time for Automatic two.
10. AUTO BR  NO:2 [0], (0 to 120) Sets the Brew time for Automatic two.
11. See steps 7 and 8 to setup auto no 2.
12. EXITING MENU End of menu, returns to Idle.
If there is no activity for thirty (30) seconds the menu function will exit and return to Idle.
The Steam AND / OR Water Actuator is used as an Enter button. On three group machines the
