CHAPTER 1
GENERAL WARNING
1.1 General Warning

4
The espresso machine DE MBM01 is intended to dispense espresso, hot water,
tea, camomile and other infusions, to create steam and to warm drinks (milk,
chocolate, cappuccino, punch, etc.).
This machine has been planned only and exclusively for the above mentioned
purposes.
All other uses are to be considered unfit and therefore strictly forbidden.
The manufacturer shall not be held responsible for damages due to unsuitable
use of the espresso machine.
1.2 Use allowed

5
The espresso machine DE MBM01, at first is wrapped up in bubble-lining and
protected with foam polystyrene then is packed in carton with pallet
Warning:
- After the unpacking, make sure that the machine and relevant equipment
are complete and undamaged.
- The unpackings must be kept out of the reach of children and disposed
at the proper dumps.
- Should you detect damage to the machine or missing pieces in the
equipment, do not use the machine and inform immediately the area
agent.
The espresso machine can be handled by means of a transpallet or a lift truck.

The water coming from the water supply by a motor pump with a pressure
ranging from 9 to 10 bar, passes through an overpressure valve set to 12 bar.
From the volumetric meter, controlled electronically, the water goes into the
boiler by means of exchanger.
The boiler water heated by a resistance, heats in its turn the water in the
exchanger, which, by means of a suction lift allows a constant temperature .
From the exchanger, the water goes directly into the group which, by an electric
valve controlled electronically by a push-button panel, allows the water to get in
for the coffee infusion.
(Refer to fig. 1)
For the description of the controls, refer to the table of the inside back cover of
this instruction booklet.
The espresso machine DE MBM01 is produced in different versions from 1 to 4
groups.
Starting from 2-group version, resistances with power above 3000 W (except
the versions feeded by 110-120 V 50-60 Hz) can be supplied, on request.
This handbook describes the 2-group version; however, use instructions and
control panel apply to the other versions too.

Make sure that the water supply installation is connected to drinkable water
supply with operating pressure ranging from 0 to 6 bar.
Should the pressure be above 6 bar, provide a reducer.
Provide an intercepting tap upstream the machine connection.
A nipple G 3/8 " is already provided for the water supply connection.
Warning: Do not turn on for any reason the threaded tap and the boiler
drain cock housed near the water supply nipple; danger of burns.
Connect a rubber pipe with inner diameter of 17 mm to the provided connector
of the machine drain well and join the open drain-trap, previously prepared.
Connect the machine as shown in the illustration 2.

Turn on the intercepting water tap.
Set the omnipolar lever switch to ON.
Setting the switch (fig. 4) in position 1 the green light and the red one will light
up.
The water is automatically supplied to the boiler and after 120 seconds the
indicators LED on the keypad will light up; repeat the above operation more than
once, till the pump has completely supplied the boiler and doesn’t start any
longer.
When you reach the minimum water level the red light (fig. 4) will switch off and
setting the switch in position (/VV ) the yellow light (fig. 4) will light up.

N.B.: Do not set the switch in position (/\/\/) when the red light is on.
In order to have the right temperature for the machine, make sure that the
pressure on the gauge is from 1 to 1,2 bar, then turn the steam knob (fig. 1; pos.
4) and let out 2 or 3 times the steam into the drain tray.
The green light (fig. 4), if on, points out the activation of the machine.
The red light (fig. 4;) if on, points out the water level in the boiler is not enough.
The yellow light (fig. 4;. ), if on, points out the activation of the heating element.
Caution: When the red light is on (fig. 4;) a safety device prevents the
machine from operating; ask for the technical assistance service.
1) Remove the filter holder from the supply group.
2) Put the ground coffee into the filter holder, press it and make attention that
the filter holder edge is not dirty with coffee.
3) Replace the filter holder in its housing.
4) Press the proper touch-key on the dose control board to supply coffee.
To change the dose programming, follow the instructions described in the
chapter 5.6 of this booklet.
The machine is preset to supply coffee in “non-stop mode” :
1) Press the “non-stop mode” key to start the supply (fig. 3; pos. e).
2) Press again the “non-stop mode” key (fig. 3; pos. e) to stop the coffee
supply.
Caution: The machine is equipped with an automatic safety device that
stops the nonstop supply after deliverying three consecutive liters.

1) In order to avoid eddies in the boiler, let off steam by turning the relevant
knob (fig. 1; pos. 4).
2) Insert the nozzle into the container with the water to be heated.
3) Turn the steam knob.
The outlet steam depends on the knob turning: the more the knob is turned, the
more the steam is let off .
4) After the steam has been blown off, turn the knob off, take out the container
and clean immediately the nozzle with a damp cloth in order to remove
residual heated water .
1) Place the water container under the dispenser (fig. 1; pos. 9).
2) Turn on the knob(fig. 1; pos. 14) to get the required quantity of water.
To program each single dose (fig. 3; pos. a ÷ d), do as follows: keep the key
[PROG] pressed (fig. 3; pos. e) of the group interested in the dose programming
till the relevant LED flashes.
Within 4 seconds press the required dose (fig. 3; pos. a ÷ d) and when the
quantity has been supplied press again the same touch-pad.
During the programming, only the leds relating to the touch-pad PROG and the
pressed touch-pad are left on.
To program another dose, repeat the same procedure; however, this time the
led relating to the dose previously programmed, will not light up, but that doesn’t
prevent the dose reprogramming .
Programming the first group, you program automatically the other groups. This
first group only, allows to transmit the programming to the others which can be
programmed also individually.
