1. INTRODUCTION

This Technical Manual describes the technical characteristics that correspond to the automatic

coffee grinders in the MO2 / CAPRICCIO range.

The M02 / CAPRICCIO range has two models:

M02 / CAPRICCIO with a display

M02 / CAPRICCIO with no display

Both models in this range can be manufactured in different colours.

1.1. DEFINITIONS

Coffee grinding point: this is the point to which the coffee beans are ground, finer or

coarser.

Espresso coffee: infusion of coffee elaborated according to the following conditions:

- 7 g of ground coffee.

- The temperature of the infusion water between 92º C and 96º C.

- The water pressure at 8 kg/cm².

- The infusion time of the coffee between 20 and 28 seconds.

- The volume of water in the infusion 40 ml.

Programming mode: when the machine is ready for any of its functions or parameters to be

programmed.

Working mode: when the machine is in the working state and ready to prepare any of the

services it offers.

1.2. PRINCIPLE TECHNICAL CHARACTERISTICS

Ô Automatic: A press of the micro switch is enough to grind and dose the programmed

dosage of coffee.

Ô It can provide one or two doses of coffee.

Ô There is the option of grinding the coffee at the moment the dose is requested or pre

grinding the coffee beforehand.

Ô It automatically changes the grinding times to always achieve equal doses of ground

coffee. With this system, the quality of the beverage is constant.

Ô Capacity of the coffee bean hopper: 1500 grams

Ô Programming the dose of coffee in “grams” or “time”:

Method Minimum dose Maximum dose Increments

Grams 5 g 20 g 0.5 g

Time 1 s 7 s 0.05 s

Note:

If the programming function <<COUNTRY CODE>> is programmed with the values 1 or 2, the

maximum dosage can be programmed up to 25 g.

Ô The grinder motor spins at 1250 r.p.m.

Ô The grinding teeth are of very high quality. Their diameter is 64 mm.

Ô All models in the range use 230 Vac.

Ô The power consumption of all the models in the M02 / CAPRICCIO range is 525 w.

2. DESCRIPTION OF COMPONENTS

1. Coffee bean hopper

The hopper is made of smoked transparent polycarbonate and the cover of ABS; it has a

maximum capacity of 1500 g of coffee beans.

The hopper has a gate that can be closed manually. It is used to block the exit of coffee beans

when it is removed from the grinder.

Tajadera cerrada

2. Coffee identification label

The hopper has a window where a label can be placed that identifies the type, variety or

quality of the coffee beans used in the hopper. It can also be used for publicity.

3. Knob for regulating the grind point

Made of POM, it is used to regulate the “grind point” of the coffee beans. Turning the knob

clockwise will make the “grind point” finer and turning the knob anticlockwise will make the

“grind point” coarser.

Never turn the knob clockwise with the grinder motor stopped.

If this is done, the compressed coffee beans will jam the grinder.

Technical information: M02 / CAPRICCIO 7

Only the third and subsequent services of ground coffee should be used after regulating

the new “grind point”

4. Display

El display is comprised of four 7-segment displays that can show four digits.

5. Programming button

Pressing on this button gives access to the deferent programming functions on these coffee

grinders.

6. button

Pressing on this button increases the value of the function you are programming.

There is no button to decrease a value. To decrease a value it is necessary to advance

through the values until you loop back to the beginning to choose a lower value.

7. button

This button is used to programme a dose of ground coffee that the grinder supplies for a single

coffee. The doses that can be programmed are:

• Measuring in time: 1 second minimum and 7 seconds maximum with increments of 0.05

seconds.

• Measuring in grams: 5 grams minimum and 20 grams maximum with increments of 0.5

grams.

8. button

This button is used to programme a dose of ground coffee that the grinder supplies for two

coffees. The doses that can be programmed are:

• Measuring in time: 1 second minimum and 7 seconds maximum with increments of 0.05

seconds.

• Measuring in grams: 5 grams minimum and 20 grams maximum with increments of 0.5

grams.

9. ON/OFF button

On the grinders that have a display, this button is used to switch the grinder on and off.

10. Programming button

This button is only on the grinders that do not have a display. It is used to go from “working

mode” to “programming mode”.

10. Coffee presser

This is used to compress the ground coffee in the filter holder. This will provide an adequate

infusion of the coffee.

The grinders have a 55 mm presser that coincides with the standard filter holder on the

market. For filter holders with different diameters it is necessary to substitute the presser for

another that is the correct diameter.

11. Micro switches

Activating the micro switches with the filter holder will dose the corresponding dose of ground

coffee into the filter holder.

12. FILTER HOLDER guide

Its function is to make the loading of the ground coffee into the filter holder easier. The

grinders have filter holder guide that coincides with the standard filter holder on the market.

For filter holders with different diameters it is necessary to substitute the filter holder guide for

another that is the same diameter.

13. Residue tray

Made of POM, this element collects the coffee grinds that fall from the filter holders during the

loading process.

14. Mains switch

This is used to switch the grinder on or off. It connects and disconnects both phases of the

mains.

15. Mains flex

It is 1500 mm long. The plug is Schucco.

16. Housing

It is divided into two pieces: the front made of aluminium and the casing made of sheet metal.

To remove the housing, follow these instructions:

• Remove the coffee hopper.

• Soltar los cuatro tornillos que fijan la envolvente.

18. Grinder

Technical Characteristics:

10087 UK 09 - 2004

Technical information: M02 / CAPRICCIO 10

Voltage 230 Vac

Power 525 w

Diameter of grinders 64 mm

Grinding teeth distance “grind point” 0,006 mm

Life of DITTING grinders ≈ 50,000 coffees

Life of CATALÁ grinders ≈ 25,000 coffees

The useful life of the grinders is reduced if the coffee mix has torrefacto coffee

(caramelised coffee)

When the grinding teeth are changed, to adjust the “grind point” of the coffee, proceed in the

following way:

• Make sure there are no coffee beans in the grinder.

• Request a dose of coffee so the grinder motor starts.

• Turn the “grind point” knob anticlockwise until you hear the top teeth touch the bottom

teeth. Now switch of the grinder.

• Turn the knob clockwise 8 “notches”. The moving grinding teeth will separate from the

fixed teeth.

• Now introduce the coffee beans into the hopper and request a ground coffee. If

necessary, adjust the “grind point” finer or coarser.

19. Brake

Its job is to maintain the grinding teeth separated at a constant distance when grinding the

coffee beans. The objective is to achieve a uniform “grind point” of the coffee.
