Coffee grinder on demand
1. INSTALLATION
Installation must be performed by a qualified technician.
The machine is delivered ready for installation according to the
data on the plate Fig. 3.
Check that the main power supply is compatible with the machine.
Check that the machine, the accessories, the supply cable and the
plug are intact, and in the event of damage, inform the retailer
promptly.
The machines have been designed and built for grinding coffee
beans for professional use.
Any other use is to be considered improper and thus dangerous.
1.1 Motor rotation
To be carried out by a qualified technician.
For machines with 3-phase electrical supply, the correct rotation
of the motor should be checked.
- Start the grinder and check that grinding is performed
correctly. If this fails to occur, it means that the motor is
rotating in the wrong direction.
- Turn off the machine and the main power supply.
- Invert the two phase conductors, reassemble the machine
and try to perform the grinding operation again.
1.2. Burr calibration
To be performed during installation and after burr replacement
The dosing grinders are tested with a random grind setting and
will need to be readjusted. This operation should be carried out
with the bean hopper empty.
Hold down the adjustment unlock button (Fig. 2-1) and at the
same time slowly turn the adjustment knob (Fig. 2-3) counter-
clockwise until the burrs brush against each other (when they come
into contact, the sound of metallic friction can be heard), turn the
numbered ring (Fig. 2-2) so that the starting point 0 is frontal;
move the adjustment knob (Fig. 2-3) in the opposite direction
(clockwise).
2. FIRST START-UP
2.1. Description of commands
KRYO 65/ST
Main switch (Fig. 1-9) with two positions; when switched on, the
machine is on and coffee grinding begins.
KRYO 65/AT
Main switch (Fig. 1-9) with two positions; in position (I), the
machine is on and will automatically shut-off when the doser
has been filled.
KRYO 65 OD
Main switch (Fig. 1-9) with two positions; when switched on, the
machine is ready for coffee grinding.
KRYO 65 OD has a startup menu to select the personal
preferences of the operator, when switched on for the first time.
Operator has to choose the language, the mode and the way to
activate the grinding. After choosing the preferences, the display
will show a message “Do Calibration”. The calibration has to be
done with the procedure shown in the software structure under
Counter/Burrs/Calibration.
This message will be shown after each preparation up to the
time, the calibration has been done.
2.2. Grind setting
The coffee grinder is tested by the manufacturer with a medium
grind setting. The setting depends on the type of coffee used.
- Place a small quantity of coffee beans in the bean hopper
and close the lid;
- Check that the hopper locking slide is open (Fig. 1–4)
- KRYO 65/ST KRYO 65/AT : Grind a small quantity of coffee.
Position the filter holder on the filter holder fork (Fig. 1-8),
then pull the dosing lever (Fig. 1a-11) to dispense a dose of
ground coffee (this operation should be performed after
adjusting the grind setting See 7.3);
- KRYO 65 OD : Position the filter holder on the filter holder
fork (Fig. 1-8) and grind coffee;
- Brew some coffee, checking the dispensing time, the
appearance of the coffee and its taste, considering that
excessively course grounds produce light coloured coffee
without a crema, while grounds that are too fine result in
strong, dark coffee without a crema.
- If the coffee does not respond to your desired requirements,
adjust grind fineness by pressing the ring block button (Fig. 2-1)
and turning the regulation knob (Fig. 2-3) counter-clockwise for
a finer grind or clockwise for a coarser grind.
- Repeat the operation until you have obtained the desired
quality of coffee.
Recalibration of the grind is typically only necessary after a change
in coffee. Minor adjustments may be required throughout use to
accommodate for changes in freshness of the beans.
2.3. Adjusting the ground coffee dose
The doses of KRYO 65/ST and KRYO 65/AT can be adjusted as
follows:
- Turn the knob below the doser (Fig. 1a-12) counter-clockwise
to increase the dose.
3. MAINTENANCE
Maintenance operations should be carried out with the machine
turned off and cold, and with the plug removed from the power
source.
Do not use metallic or abrasive tools, such as steel wool, metal
brushes, needles, etc., or detergents (alcohol etc.), but simply a
damp cloth or sponge.
3.1. Daily
- Clean the housing and the grounds tray.
- Clean the filter holder fork area.
- Clean the coffee outlet with a brush.
3.2. Periodically or after intense use
Empty the bean hopper, and clean it of oily residues left by the
coffee with a mild soap solution.
Waste materials used for processing or maintenance, if not
biodegradable or pollutant, should be placed in separate
containers and taken to suitable collection centers.
