Page 5: Operating Principle
OPERATING PRINCIPLE General operation The machine works according to a pump system developed by Bravilor Bonamat. This system has the following advantages: D The components that ensure that the water is dosed properly are in the cold water circuit. This reduces the main cause of failures, namely the formation of limescale on the dosing valves, to a minimum. -
Page 6: Starting Up The Machine
Starting up the machine 1.3.1 Boiling point determination program Hot water may come out of the hot water outlet while this program is running. The machine automatically runs through the boiling point determination program the first time the machine is used. -
Page 7: Filling The Machine
1.3.3 Filling the machine The float tank and the boiler are connected by a siphon hose. Together they create a communication entity. When the machine is switched on for the first time the float tank (Fig.2) is empty and the float (Fig.2,A) in a lowered position. -
Page 8: Dosing
1.3.5 Dosing Dosing takes place when: D The float is in the highest position. D The second temperature sensor measures a temperature that is higher than the blocking temperature. D Pressing a selection button starts the pump motor (Fig.5) at a certain speed (rpm) for a given amount of time based on the programmed amount. - Page 9 After the machine has been switched on, the water selector goes into stand−by according to the following procedure: D The water selector motor is triggered. D This motor drives the water rotation disc with a plastic worm (Fig.9/10). D The shafts on the rotation disc interrupt the light beam emitted by the light sensor and transmit the pulses to the controls (Fig.11).

Page 10: Powder Dosing System
Powder dosing system The powder dosing system consists of an ingredient canister that is driven by the canister motor. Pressing the start button starts the canister motor after a certain delay. This motor drives a worm, which transports the ingredient to the canister’s outlet. The controls for the canister motor enable the timing and the dosing speed to be controlled independently. -
Page 11: Ventilation System
Ventilation system The ventilation system (Fig. 17/18) ensures that the hot steam that is produced during dosing can escape. This prevents the hot steam from settling and condensation from forming in the mixing chamber. This substantially decreases the amount of filth that can settle in the mixing chamber. Fig. -
Page 12: Adjusting The Brewer
1.7.1 Adjusting the brewer 1.7.1.1 Clamping force The clamping force of the brewer chamber must be set in order to prevent too much water from leaking through the filter paper. You can see if water is leaking by checking the filter paper. If the filter paper is wet for more than one centimetre all round after a cup of coffee has been made, too much water is leaking. -
Page 13: Bypass
− Always check the clamp in the brewer chamber before adjusting the paper transport. Changing the clamping force of the brewer chamber will affect the paper transport! WARNING − Turn the adjustment bolt in a closed position so it cannot be turned too far. D Hold on to the adjustment bolt (2.) and loosen the locknut (1.). -
Page 14: Coffee Grinder
Coffee grinder We recommend checking the coffee grinder and the coarseness of the ground coffee periodically and to maintain the grinder according to the below table: Coffee beans Action: After the first 30−50 kg: Check the coarseness of the ground coffee Clean the coffee grinder After every 300 kg: Calibrate the coffee grinder if necessary... -
Page 15: Calibration
1.9.2 Calibration 1. Switch off the machine. 2. Slowly turn the flange [4] clockwise until the grinding discs just touch each other (you will hear a grinding like sound). 3. Turn the flange [4] back 21 holes (= 42 clicks) (1 hole is equivalent to about 0.022 mm in height). 4. -

1.10 Operating system The operating system consists of a: D Keyboard D Control board 1.10.1 Keyboard The keyboard is the circuit board with LCD and press buttons. Settings that can be changed in the program menu are also saved in the Eeprom of this circuit board. Replacing the keyboard returns the machine to its factory settings. -
Page 17: Software Protection
1.12 Software protection Depending on the type of machine, it will have a number of software protections. The software monitors all of the machine’s inputs and outputs during the whole process. The software intervenes when a situation occurs that shouldn’t. This intervention usually results in the machine being switched off and an error message displaying on the LCD. -
Page 18: Programming
1.13 Programming The program in the FreshBrew machines consists of a simple program carousel. Refer to the user manual while reading this text. Pressing the program button activates the program and enables you to activate or change settings. Pressing the program button again saves the settings and returns the machine to stand−by mode. 1. - Page 19 3.2 Setting the day counter to zero: D Press one of the selection buttons to select a drink. D Keep pressing the selection button until the day counter displays 0. Fig. 30 Day counter Fig. 31 Day counter at zero D Press Enter to return to the general selection screen (Fig 32).

(For example, for a cup that holds 220 ml, the first cycle is dosed at 170 ml and the second at 50 ml.) If the setting for maximum extra mixing is changed (e.g.
