1. General operation

The machine works according to a pump system developed by Bravilor Bonamat.

This system has the following advantages:

• Many of the parts ensuring correct dosing of the water are in a cold water circuit.

This minimises the main cause of failures, being the forming of scale on the dosing valves.

• The oat regulating the water level is also in the cold water circuit.

This also minimises scaling.

2. Water dosing system

After having started a selection, the pump motor is controlled with a regulated time and speed.

The pump rotor moves a certain amount of cold water from the cold water reservoir to the bottom

of the boiler. This pushes the hot water in the boiler up towards the water selector. This selector

chooses its position by means of a rotating movement. Dependent on the recipe, the water

selector will also dose through the bypass and therefore choose a different position.

3. Start up

3.1 Initialisation

The machine is switched on using the main switch. The display shows the version number of

the software downloaded in the factory and after this the display will show all symbols and “init”

to indicate that the machine starts initialisation. During this initialisation, the machine will run a

standard routine to make sure that a number of essential components have been connected and

are operating correctly. The machine will generate an error when a component has not been

connected for any reason or is defective. When everything goes well, this process will take about

15 seconds.

3.2 Installation

When switching on the machine for the rst time, the installation programme “rst start” must be

run. The machine will have to run its boiling point determination programme and while running

this programme, hot water can come out of the outlet (see 3.4). Calibrate the pump motor after

having run the boiling point determination programme.

This calibration will take place in 2 steps:

1. The machine will calibrate the pump motor for dosing on the coffee.

The machine will dose through the lter pan. Collect the quantity of water to be dosed and

enter this into the display.

Repeat the procedure when the quantity deviates too much.

2. The machine will now calibrate the pump motor for dosing on the coffee and tapping hot

water at the same time.

The machine will now dose through the lter pan as well as through the hot water tap.

Collect the quantity dosed through the lter pan and enter this quantity in the display.

Repeat the procedure when the quantity deviates too much.

When both calibrations have been done, the machine is ready for use.

3.3 Fill

The oat tank and the boiler are connected by a siphon hose. Together they form communicating

vessels.

When the machine is switched on for the rst time, the oat tank is (Fig.3) empty and the oat

(Fig.3,A) is its low.

• The magnetic valve (Fig.1) is opened and lls the oat tank with a pressure-independent

speed with water. This lling speed is type-dependent, being 5 litres per minute for the Twin

version and 6 litres per minute for the Single version.

• The water in the oat tank runs through the hose below the oat tank to the boiler.

• After the water level has pushed up the oat, the water level in the oat tank is equal to that of

the boiler. The magnetic valve is switched off.

If the machine is a Twin version, the other side will now be lled following the same procedure.

Note:

► As the oat tank lls up faster than the water ‘drops’ into the boiler, the lling process will

take place with short intervals.

3.4 Boiling point determination programme

Hot water may come out of the lter pan while running this programme.

The machine automatically only runs the boiling point determination programme when using the

machine for the rst time. The boiling point of the water is now determined. This is necessary

because the boiling point depends on the local atmospheric pressure. The boiling point at sea

level will be about 100°C, whereas the boiling will drop to about 97°C at an altitude of 2000m.

After having switched on the mains voltage, the water in the boiler will rst be heated to about

75°C at full power (Fig.6,A).

Then the water in the boiler will be heated with reduced power to 85°C. During this period, the

software will measure how quickly the water is heated.

Based on this measurement, the machine will heat up with a certain power until the temperature

sensor on the outside of the boiler has not detected a temperature change for some minutes

(Fig.6,B). After this period, the boiling point has been reached and the measured value is saved in

the software.

The nal operating temperature in the boiler will be 3°C below this point. Because the boiling

point of water depends on the atmospheric pressure, it is necessary to run this programme at the

location where the machine will be used. During the boiling programme, the display shows the

current temperature with below this a ashing thermometer and a changing, increasing volume.

After a certain period (dependent on the power the machine has been connected to), the

thermometer stops ashing to indicate that the boiling point has been determined.

Note:

► While running the boiling point determination programme, it is very important that no

panels have been removed from the machine.

The fact is that this may inuence the measurement and so cause a deviation in the

temperature during normal use.

3.5 Heating

Now the system has been completely lled with water, a relays will enable the element.

The machine has been provided with a smart boiler routine, which basically works as follows:

• The lower temperature sensor measures the current temperature of the water.

The temperature sensor makes sure that the water in the boiler is heated to the desired nal

temperature.

• The centre temperature sensor is responsible for releasing or not releasing the selections

volume 2 and volume 3 for dosing.

• The upper temperature sensor is responsible for releasing or not releasing the volume 1

selection for dosing (if set, the airpot selection will be released as well).

• The heating switches off when the set temperature has been reached. Hot water has a lower

specic weight than cold water. As a result, the hot water in the boiler will not ow back to the

oat tank through the siphon hose at the bottom. Therefore this part of the system will remain

cold. This is very important because the parts in the oat tank are sensitive to scaling.

3.6 Dosing

Dosing takes place when:

• The oat is in the upper position.

• The uppermost temperature sensor measures a temperature higher than the blocking

temperature.

• After having started a recipe, the pump motor (Fig.7) will for a certain period be controlled with

a set speed (rpm), dependent on the programmed recipe.

Fig.7 Pump motor + rotor Fig.8 Pump housing

• The pump rotor rotates in the pump chamber that has been lled with water.

This is formed by the bottom of the oat tank and the bottom of the pump housing (Fig.8).

• The pump rotor pumps the water out of the pump chamber through the siphon hose at the

bottom of the boiler.

• This presses the hot water out of the boiler.

• The oat and the magnetic valve make sure that the correct level of water in the oat tank is

maintained and so water remains in the pump chamber.
