o It is measured with the test strip provided with the machine.
o The unit of measurement is the ° French (° TH) or the ° German (° dH).

 What is the Karbonat Hardness of the water?

o This is the amount of Carbonate Calcium ions and Carbonate Magnesium ions in the

water.

o These ions are completely responsible for limestone formation.
o It is measured with chemical dropper testers.

o The unit of measurment is ° Carbonate (°KH)

There are 2 types of water treatments:

 Salt water softeners

o They treat the total water hardness (°TH)
o By an exchange of sodium ions with calcium and magnesium ions.
o They require periodic regeneration of the resins by the user.
o To use when the water hardness is > à 10°TH or > 5 °GH

 Resins filters :

o They treat the Carbonat hardness water (°KH)
o By fixing carbonate ions on the resins.
o Often fitted with microfiltration and carbon filtration.
o To use when the Carbonat Hardness is > à 6°KH
o Highly 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 11

 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:

o The same button or
o The STOP button (which is also the programming and continuous flow button).

20 POWER MANAGEMENT

The Monte Carlo machines are three phase machines
When the machine is connected to a three phase network, the absorbed power consumption does not need to be flanged.

In this case the Power Management is at its maximum position: 6.
The machine can be connected to a single phase 230V.

In this case:
1: Change the power cable with a cable 3x6 ² (Conti reference: 103600)
2: Depending on the available amperage on the grid (16A / 20A / 32A):
It is necessary to adjust the power consumption of the machine.
Through the Power management (see table below)
3: Here's how to connect the 3x6 ² cable on the general relay machine

Nota Bene:
It is possible to retain the original cable (5x2,5 ²), but in this case:
It is imperative to curb the power management 1 (or 2 maximum if the machine is not used too much)

Power parameters and Current comsumption (for 230 volts monophase)

Power 1/2/3/4/5/6:

That’s the number of heating element can be supplyied at the same time in the machine
The priority is always given to the coffee Boiler
