Using the dispenser
Quick start
Remove the dispenser from the carton and place on a stable worktop capable of
supporting a minimum of 50kg/m. (80kg/m for A-FK)
Connect the dispenser to a source of potable water at a pressure between 0.5bar
minimum to 10bar maximum. Use a local water authority approved non-return valve
between the hose and the water supply connection point to comply with local and
federal codes. Turn on the water supply and check there are no leaks.
Connect the machine to a source of electrical power in either of the following ways;
• For 230v single phase up to 16A, use the power cord supplied with the
machine.
• Qualified technicians only: - For 3 phase power, remove the 2 screws in the
small panel containing the power switch at the rear of the dispenser. Draw out
the power supply unit and remove the cover. Pass a suitably rated (minimum
16A per conductor) 5 core power cable (3ph + N + E) through the cable gland
and secure the cable by way of the clamp in the gland. Connect the
conductors to the screw terminals on the PCB in the following way: -
1. Brown wire (first phase) to terminal L1,
2. Second live phase to L2,
3. Third live phase to L3,
4. Blue wire (Neutral) to terminal N
5. Green and yellow wire (Earth) to the terminal marked with the ground
symbol.
Make sure all connections are secure and refit the cover. Refit the power
supply unit into the chassis and replace the screws.
Connect to the building power supply using a suitable 5 pin IEC Plug rated at 16A
minimum per pin.
Switch on the machine by operating the red switch on the rear of the dispenser, it will
illuminate when power is present. You should then observe the following:
1. The display and lighting on the front panel will illuminate.
2. The display will show a name (e.g. Kaffee Konzepte or AROMAT) on the top
line and the word ‘Filling’ on the lower line. The machine will perform a ‘self
check diagnostic’ for a couple of seconds then the water inlet valve will open
and the boiler will begin to fill.
3. When the boiler is full, the water inlet valve will shut off and the display lower
line will change to ‘Heating’. When the boiler reaches 65°C the display will
change to show the time and boiler temperature on the lower line. The boiler
will continue to heat until it reaches the preset maximum temperature. (The
temperature and the time are adjustable in ‘Engineer mode’).
Place a can or BIB of coffee concentrate into the cooler unit of the machine in either
of the following ways;
FK Range - Coffee dispensers
- 5 -
• For a can: Defrost the can fully and give it a shake to stir up the coffee solids.
Open the ring pull and insert the suction tube into the can.
• For a BIB: Defrost the BIB fully and give it a shake to stir up the coffee solids.
Firmly attach the suction tube connector to the BIB.
Prime the system with concentrate by pressing and holding the ‘Prime’ button on the
inside of the front door panel until coffee is seen to drip from the outlet nozzle.
Briefly press the ‘Flush’ button to wash out the nozzle.
If powder hoppers are fitted to the dispenser (FK12) fill these to the top with
appropriate drinks powders (commonly chocolate and milk).
The dispenser is supplied with a selection of pre-programmed drinks and is ready to
use.
Refilling Coffee Concentrate
When the coffee concentrate runs out, the message, ‘Coffee empty’ will be shown on
the display, and further coffee based drinks will no longer be dispensed. Refilling the
concentrate by replacing the empty can/BIB with a full one and pressing the ‘Prime’
button on the inside of the door until coffee drips from the nozzle, will reset this
display message and re-enable the coffee based drinks.
Chocolate etc. will continue to be dispensed if there is product available. In the case
of an FK20 when set to 1 product and two cans or BIBs are being used, the
cans/BIBs will both be used before ‘Coffee empty’ is displayed.
Refilling Powder products
When the powder products become low (approximately 1/3 full) then the display will
show either ‘Chocolate low’ or ‘Milk low’, refill with powder to the top of the hopper
and then press the ‘Up arrow’ to reset the milk counter and the ‘Down arrow’ to reset
the chocolate counter. The dispenser will continue to operate, but the drinks quality
will be affected if the hoppers are left to empty completely.
Cleaning the dispenser
Semi-automatic cleaning cycle
The dispenser has a semi-automatic cleaning cycle which will cause the front panel
lights to blink at a preset time, and the message ‘Run clean cycle’ to be shown in the
display. When the lights blink, the dispenser will continue to dispense drinks, but the
lamps will blink until the cleaning function has been completed. (Attention: do not
interrupt the cleaning cycle).
To perform the cleaning function, do the following:-
1. Fill the cleaning bottle supplied with the dispenser or a container of 750ml
minimum capacity with hot water from the machine. (For FK20 fill two bottles).
2. Open the dispenser door and press the ‘FLUSH’ button inside.
3. Remove the can/s of coffee or the BIBs from the cooler, clean the suction
tubes with a cloth and replace the can/s by the bottle/s with hot water,
ensuring each suction tube is in a bottle. If BIBs are used remove them from
the cooler and screw the cleaning adapter provided with the dispenser on the
BIB connector. Ensure that each suction tube is in a bottle.
4. Place a receptacle of 2 ltr minimum capacity under the coffee outlet nozzle
then press the (enter) button.
5. The dispenser will then perform the cleaning functions.

6. Remove the cleaning bottles and/or the cleaning adapters.
7. When the cleaning function is completed the lights will cease blinking and
remain on. The cleaning cycle must be fully completed before the blinking will
stop.

To flush out the valves and mixers press and hold the ‘FLUSH’ button for a minimum
of five seconds.

detergent added to remove splash marks etc. Do not use abrasive cleaning
materials, or solvents.

on until there is sufficient water in the tank that the Water reading is lower than
the TRIP POINT.
