3.2 During installation
The installation (electrical connections, water supply and drainage) must be carried out by
a qualified technician approved by CONTI.
The machine must be connected to a device conforming to the standards of the country
where the machine is installed. Potential costs of equipment compliance are the only
responsibility of the customer.
For any technical intervention, the machines must always have the power disconnected
from the mains.
An effective earth connected to the terminal provided for this purpose on the device is
mandatory
A screw located under the bottom base machine, allow if necessary, to connect several
machine on an equipotential way.
Devices for disconnection from the main supply, having a contact separation of at least
3mm in all poles, must be provided in the fixed wiring in accordance with the installation
rules.
3.3 During the use
When the machine is not operating, the water cut-off valve has to be closed and the

4 INSTALLATION
4.1 Standby In case of a standby of the machine (standby = 2 months):
The first thing to do is to test your machine in a lab.
If the machine stops running for a long time, you could have sediment in some places.
More precisely in small area like the spray nozzle.
4.2 Protections
It is necessary to place before the machine:
oA water shut off valve.
oAn electrical protection standard, suitable for voltage and power consumption.
4.3 Water supply
Recommended operating pressure from 1.5 MPa to 6 MPa
Water connection pin 3/8"
The water supply pipes must resist to 145 Psi / 10 MPa
4.4 Drain
Without pressure.
A tip on the outlet of the machine and a pipe is supplied with the machine
Ensure a connection that causes no risk of fluid return, and ensure good drainage:
The drain pipe must be located lower than the machine.
Do not create a bend in the exhaust tube.
4.5 Supplying voltage
To be specify when ordering : 230V –50/60Hz Monofase
Or : 400V –50/60Hz Trifase

MONTE-CARLO - 11/2015 - SOFT V 2.11 6
4.6 Water softeners
When the mains water has a high hardness (>10°TH ou >4 °KH), it is recommanded:
oTo use a water treatment
oTo regenarate regularly the filters.
What is the total Hardness of the water ?
oThis is the amount of calcium and magnesium ions in the water.
oThese ions are partly responsible for limestone formation.
oIt is measured with the test strip provided with the machine.
oThe unit of measurement is the ° French (° TH) or the ° German (° dH).
What is the Karbonat Hardness of the water?
oThis is the amount of Carbonate Calcium ions and Carbonate Magnesium ions in the
water.
oThese ions are completely responsible for limestone formation.
oIt is measured with chemical dropper testers.
oThe unit of measurment is ° Carbonate (°KH)
There are 2 types of water treatments:
Salt water softeners
oThey treat the total water hardness (°TH)
oBy an exchange of sodium ions with calcium and magnesium ions.
oThey require periodic regeneration of the resins by the user.
oTo use when the water hardness is > à 10°TH or > 5 °GH
Resins filters :
oThey treat the Carbonat hardness water (°KH)
oBy fixing carbonate ions on the resins.
oOften fitted with microfiltration and carbon filtration.
oTo use when the Carbonat Hardness is > à 6°KH
oHighly recommended by the manufacturer :
The machines are equipped with suitable protection in accordance with flowrate
and the water encountered.
The changing cartridges is carried out by the technical service, at intervals to
be determined

7 HOW TO USE THE MACHINE
7.1 Operating elements
STEAM FUNCTION
Two steams taps levers « V » are provided to allow:
The heating of liquids by spraying steam.
The milk foam production to create Cappuccino or Macchiatto.
The liquid to be heated should preferably be placed in a deep container.
The tip of the steam wand outlet must be immersed in the liquid, without touching the bottom of the
container.
The steam may also be used to sterilise and warm glasses.
After each use and absolutely after heating milk, always clean the stainless steel steam nozzle and
the outlet nozzles with a damp cloth, removing all traces present.
A rinsing of the steam lance inner holes is to be done by a short pulse on the lever downwards to
release a jet of steam.
HOT WATER FUNCTION
Two electric taps “E” are provided for preparing tea, grog, etc.
Be careful, not to be burnt by the pressure water spray.
For that, the valve is coupled to cold water mixing for adjusting the water T° for tea and avoids spitting
hot water.
Each electric tape is controlled with 2 buttons for 2 different times

MONTE-CARLO - 11/2015 - SOFT V 2.11 12
FILTERS
The machine is equipped with two types of filters: 1 cup (10 G) and 2 cups (18 G)
Each filter is operating with its own holder-filter to produce respectively 1 cup or 2 cups of coffee.
Filters need to be unclogged and clean, so they need to be cleaned almost once a day with hot water,
by being removed from the holder filters.
Take care to remove all residual traces of coffee and ensure proper cleanliness of perforations in the
bottom of the filter.
FILTER-HOLDER
Never remove the filter-holder during operation of the group. The shutdown is controllable with coffee
spouts: they no longer have to eject liquid.
Be careful to always keep the filter-holder engaged in the group, emptied of coffee cake, to keep them
warm.
In case of an extended stopping period, remove the filter-holder from the group, taking care to eject
the used grounds remain in the filter-holder.
Tighten the filter-holder until to be in contact with the seal, exceeding a little bit. The sealing is
guaranteed.
Do not unnecessarily try to crush the seal by tightening the filter at the maximum of your possibilities.
It may damage the seal prematurely.
To empty the coffee filters used, turn the filter holder upside-down and lightly tap it on the edge of a
wooden box. Never strike it against metal or other hard objects.
DIGITAL MANOMETER M1 : BOILER PRESSURE
The boiler pressure is adjusted in factory between 0,8 MPa (12 PSI) and 1 MPa (15 PSI). This value
varies slightly around its nominal temperature, due to the PID system which controls the heating and
limits the current consumption to its minimum.
Factory settings: 1.2 MPa with setting range from 0.8 MPa to 1.4 MPa .
NOTE: An over-heating thermostat cut the power on the general relay, in case of an abnormal high
temperature. The machine is not anymore supplied.
DIGITAL MANOMETER M2 : PUMP PRESSURE
The pump pressure is adjusted at 9 MPa in the factory. Value which allows the best extraction of
coffee flavors. A bypass system evacuates over-pressure.
NOTE: Simultaneous operation of all the groups can impact a little bit the pressure level.
Visualization of the presence of water network is done by consulting the gauge
7.2 How to use the programmed doses
Simply select one of the buttons available on each keypad to obtain the doses or the
programmed drinks.
The selected dose is shown by a blinking led on the keypad.
The flow can be stopped by repressing:
oThe same button or
oThe STOP button (which is also the programming and continuous flow button).
