Rev. 02.09

1. general notes

• The first part of this user's manual briefly explains the method of making espresso coffee, the modern

equipment used and the function of the grinder-dispenser in this delicate process.

1.1 The espresso coffee

Espresso is a coffee prepared with a particular brewing process, which makes it possible to make a very
concentrated, syrupy beverage of intense taste and aroma. The method of preparation of espresso consists
of extracting the substances contained in ground coffee by passing through it a flow of hot water under pres-
sure (about 9 bar) for 25 to 35 seconds. In this manner, the soluble substances (sugars and proteins) and the
insoluble materials (fats and colloids) in the coffee are "drawn out" into the cup, forming the characteristic
cream of real espresso. The preparation of espresso is a very delicate process; various factors affect the
success of this operation: the preservation of the coffee beans, the grinder-dispenser and the grinding proc-
ess, the preservation of the ground coffee, the espresso coffee machine itself, the changeable weather con-
ditions, and the care and attention of the operator in making the espresso coffee.

1.2 Storing the coffee beans

There are two varieties of coffee found in nature: the "arabica" variety and the "robusta" strain. Normally, the
roasted coffee used to make espresso contains a mixture of the two varieties, suitably blended in varying
percentages, taking into account the organoleptic characteristics of the individual components. The blend of
roasted coffee must be kept hermetically sealed inside its package. The roasted coffee beans contain within
them all the principles and characteristic aromas of the variety or the blend; these aromas fade rapidly when
the coffee beans come into contact with air, light and humidity.

1.3 The grinder-dispenser and the grinding process

The grinder-dispenser is a device designed to grind and dispense the coffee. To make a good espresso, the
coffee should be ground to particle sizes ranging from about 1 mm to a powder finer than 150 µm. Powdered
coffee offers a greater contact surface to water, allowing a greater extraction of soluble and insoluble sub-
stances. By varying the particle sizes of ground coffee, it is thus possible to modify the resistance offered
against the passage of water. If the ground coffee is made up of excessively coarse particles, the serving
time is too short, the water does not manage to extract all the qualities of the ground coffee, and the result-
ing espresso is light in colour, thin, bland and lacking the characteristic coffee aroma. When the ground cof-
fee is too fine, the espresso brewed is dark, burnt and cold; the serving time is too long and the water pas-
sage is too sluggish since the fine powder offers an excessive resistance to the water flow. The resulting
espresso is too strong.

1.4 Storing the ground coffee

Ground coffee is much more sensitive than coffee beans: the dispersion of aromatic substances takes place
very rapidly if it is kept in open containers and in moist environments. The coffee beans should be ground in
small quantities and the ground coffee should be used in the shortest time possible.

1.5 The espresso coffee machine

The espresso machine is a device that consists essentially of a boiler and a series of heat exchangers, in
which water is heated by an electric heating element or a gas burner. Water heated to a high temperature is
made to flow through the ground coffee placed in the filter cup and extracts its aromas. When this manual
talks about espresso coffee machines, this refers to all "continuous serving" models with hydraulic unit, and
to the manual piston type (known as lever operated). La San Marco S.p.A. grinder-dispensers are profes-
sional devices designed and built to be used with this type of espresso coffee machine.

1.6 Climatic conditions - Operator

As already mentioned, to make a good espresso it is essential that the coffee be ground to a proper particle
size. Ground coffee is very hygroscopic; in other words, it "senses" the moisture in the air and grinding should
therefore be modified to suit varying climatic conditions; a ground coffee with a high moisture content increas-
es the resistance to the passage of water. Other important factors in the making of espresso are the quantity
and compactness of the ground coffee inside the filter cup. These factors (moisture, quantity and coarseness
of the ground coffee, compactness) must be considered and weighed by the operator making the espresso.
For these reasons, the operator has a very important role in the espresso coffee-making process.

3. technical characteristics

3.1 General characteristics of the different models

The La San Marco grinders-dispensers are professional equipment designed for grinding and metering cof-
fee beans. La San Marco S.p.A. manufactures four basic grinder-dispenser models: SM 91; SM 96; SM MK;
SM FK. They are essentially made up of:
• A painted aluminium housing

. The size, shape and volume are identical for all models, except models

SM MK and SM FK, in which the standard housing is provided with a base

that contains the electrical

and electronic components.

• A hopper

, made of transparent plastic material, positioned on top of the grinder-dispenser. The hopper

4,6 litre is fixed to the grinder-dispenser by a special screw

. The hopper can only be removed with the

help of an appropriate tool. Inside the hopper there is a safety grid

that prevents the upper limbs from

accidentally coming into contact with the grinders.

• An electric motor on which the grinding unit is connected. On the grinder-dispenser unit, model SM MK,

an epicycloid reduction is connected between the motor and the grinding unit.

• A grinding unit. Model SM 91 and model SM 96 are equipped with a grinding unit with flat grinders of 64

mm and 84 mm diameter, respectively. Model SM MK has a grinding unit with one conical and two flat
grinders, while model SM FK has a grinding unit with conical grinders.

• A grind adjustment ring

with a release button

. The top of the ring shows the grinding adjustments

possible. The ring is turned clockwise or counterclockwise to change the fineness of the ground coffee.

• A dispenser

designed to measure and dispense the ground coffee; it has an adjustment range from 5

to 9 grams or, in the increased dose configuration, from 6 to 10 grams. The amount of ground coffee
dispensed can be adjusted by operating on the control knob

, located inside the dispenser.The ground

coffee is dispensed by pulling on the coffee dispensing lever

. The presser

, available on cylindrical

and conical versions, enables the ground coffee to be pressed down inside the filter cup.

• A support fork

for the filter cup.

• An electronic control unit that controls the coffee grinder start and stop. The grinding time can be pro-

grammed on the electronic control unit and the grinder-dispenser can be made to restart after a desired
number of ground coffee servings.

• An on/off main switch

with green LED.

4.1 Warnings

The  machine  must  be  installed  by  qualified  technical  personnel  authorized  by  La  San
Marco S.p.A.
The grinder-dispenser is delivered to the customers in a suitable cardboard and styro-
foam  package.  The  package  contains  the  grinder-dispenser,  its  accessories,  the  user
manual  and  the  compliance  declaration.  After  having  opened  the  package,  check  the
integrity of the grinder-dispenser and its components; in case of doubt, do not use the
appliance and contact the qualified personnel of the La San Marco S.p.A. service centres.
The package should be disposed of through the proper waste collection centres, in com-

pliance with the laws of the country where it is installed. Do not discard it in the environment. The packing
elements (carton, styrofoam, metal staples, etc.) can be hazardous. Keep away from children!
Place the grinder-dispenser on a perfectly horizontal surface that is sufficiently sturdy to support it, stable and dry.

4.2 Electrical connection

Instructions for a proper electrical connection of the grinder-dispenser:
• Before connecting the appliance to the power supply, make sure that the tag data of the grinder-dispenser

are the same as the network power supply; the rating tag is located under the grounds collecting tray.

• The connection must be made in accordance with the provisions of the country where the machine is

in-stalled.

• The electrical system prearranged by the customer must be in compliance with applicable standards. The

power socket must be provided with a suitable ground conductor. La San Marco S.p.A. declines any
liability if the prescriptions of the law are not complied with. An improper installation can cause damage
or personal in-jury, for which the manufacturer cannot be considered liable.

• If it is necessary to use adapters, multiple sockets and extensions, use only products in compliance with

the safety standards in force.

• Unwind the power cable completely to avoid overheating it.
• The single-phase grinder-dispensers are provided with a three-conductor power cable and a plug for

connec-tion to the power socket.

• For the electrical connection of the three-phase models, install an omnipolar main switch upstream of the

power supply; the main switch must have the same electrical characteristics (power and voltage) as
shown on the machine rating tag. The main switch must be able to break the power supply with a contact
gap of at least 3 mm.

• The three-phase grinder-dispensers are equipped with a five-conductor power cable. The connection of

the three-phase models must be carried out as follows: (star connection for the models with 400V-3N~
power supply and delta connection for the models with 230V-3~ power supply).

• At the completion of the electrical connection, check that the motor turns in a clockwise direction (looking

at the appliance from above); if it turns counterclockwise, reverse two power phases.

• If the power is transformed from 400V-3N~ to 230V-3N~ or vice versa, use the adhesive labels provided

with the machine to update the data shown on the label glued at the end of the power cable.

4.3 Programming the grinding time

The electronic control unit controls the grinding time and restarts the grinder-dispenser after a certain number
of batches of ground coffee are dispensed. The unit is programmed by the manufacturer according to
preset values (see table). The grinder-dispenser, started with the push button

, remains active and stops at

the end of the preset grinding time or is stopped by the action of the
overflow limit switch, which resets the timer. The grinder-dispenser
starts again after a certain number of batches of ground coffee,
based on the impulses given by the lever

, and stops at the end of

the preset grinding time or, as already mentioned, it is stopped by the
action of the overflow limit switch. The installer can modify the set-
tings on the electronic control unit if the user of the appliance
requests different parameters from those preset by the manufacturer.
Instructions for a proper adjustment of the grinding time:
• Disconnect the power supply.
• Lean the grinder-dispenser on one side and remove the bottom;

the electronic control unit, which controls the grinding time, is located inside the grinder-dispenser.

• Set, in agreement with the user of the appliance, the grinding time and the number of impulses to start/

stop grinding.

• To set the agreed parameters, adjust the dip switches located inside the electronic control unit (see fig-

ure). Dip switches 1 and 2 control the grinding time; it is possible to set a grinding time from 30 to 120
seconds. Dip switches 3 and 4 control the impulses given by the coffee dispensing lever; it is possible to
restart the grinder-dispenser after 6, 12, 18 or 24 batches dispensed.

4.4 Grinding Adjustment

Instructions for a proper adjustment:
• Fill the hopper

with the coffee beans and open the gate

• Start the grinder-dispenser by pressing the push button 3. Grind a small amount of coffee and switch off

the unit by pushing the stop button

• Check the fineness of the ground coffee. Make one or more cups of espresso coffee and check the coffee

served into the cup (the “ideal” quantity for brewing a cup of espresso is 6 to 8 grams of ground coffee,
with a time of 25 to 30 seconds). There may be three different cases:

a) The coffee brews too slowly: the coffee is ground too fine (it should be coarser). To make a coarser grind,

press the release button

and turn the adjustment ring

clockwise.

b) The coffee brews too fast: the coffee is ground too coarse (it should be finer). To make a finer grind, press

the release button

and turn the adjustment ring

counterclockwise.

c) The coffee brews at the proper speed.

4.5 Changing the coffee grinders

When changing the coffee grinders, the adjusting ring nut must be inserted so that the hopper locking screw
(

) does not interfere with the grinders stop pin (

The proper grinder change procedure is as follows:
Loosen the hopper locking screw completely and pull out the hopper.
Loosen the three M5x12 grub screws located on the grinder support ring nut and remove the adjusting ring nut.

Unscrew the upper grinder support and remove it from its seat.
Replace the grinders and align the lower grinder with the three scraping teeth (the distance from these teeth
is 0,9 mm; to center the machine we suggest using a thickness gauge).
Clean the grinder seats and the thread of the upper grinder support accurately.
Screw the upper grinder support down to where the upper grinder grazes the lower one; this operation

should be carried out with the coffee grinder-dispenser in rotation in order to determine the exact point at
which the two grinders come into contact with each other.
Finally, insert the adjusting ring nut, making sure that the hopper locking screw is slightly ahead of the
grinder stop pin, in a counterclockwise direction, as shown in figure 1. Figure 2 shows a faulty installation of
the adjusting ring nut: the hopper locking screw (

) is after the grinder stop pin (

It is important to remember that in this case the hopper locking screw will not allow the grinder stop pin to
be passed in the grinder opening phase, which, since the grinders are already in contact with each other,
would make it impossible to grind the coffee to the proper degree of fineness, and the brewed coffee would
not flow out of the spout or would just drip out.

4.6 Adjusting the quantity of ground coffee

Instructions for properly adjusting the quantity (grams) of ground coffee:
• The batch of ground coffee is controlled by means of the adjusting knob

located inside the dispenser

• To decrease the amount, remove the lid from the dispenser and turn the knob clockwise; to increase the

amount, turn the knob counterclockwise.

• We suggest dispensing ten batches of ground coffee and weighing them with an electronic balance. The

average batch should be about 7 grams (suggested quantity).

5. operating instructions

5.1 Using the grinder-dispenser

Instructions for a proper use of the appliance:
• Fill the hopper

with coffee beans and open the gate

• Timer model SM92T: start the coffee grinding by turning the manual timer clockwise; grinding stops when

the set time has elapsed. Turn the timer back to "zero" if you wish to stop grinding before the set time.

• Manual model with the automatic timer SM92A - SM97A - SMLK - SMTK: start the grinder-dispenser by

pressing the main switch

; the green LED lights up in the push button (showing that the unit is con-

nected). The electronic control unit stops grinding at the end of the set time; grinding can be stopped at
any time by turning the main switch

to position "zero". Motor restart based on the number of ground

coffee servings is programmable and may take place after 6, 12, 18, or 24 servings.

• Manual model SM92 - SM97: same characteristics as the automatic version, except for the “overflow”

grinding shutdown function and motor restart based on the number of ground coffee servings.

• The ground coffee is dispensed from the dispenser

by operating the lever

• Place the filter cup on the support fork

and pull the lever (toward the operator) to dispense a batch of

ground coffee. Every complete movement of the lever corresponds to one batch.

• Press the ground coffee using the press

; insert the filter cup in the machine serving unit and start the

coffee serving.

5.2 Practical suggestions for the operator

• Keep the coffee beans in sealed containers in a dry environment at room temperature.
• Never leave large quantities of ground coffee inside the dispenser for long periods (for example: during

the off day).

• Check from time to time the fineness of the ground coffee and the quantities dispensed, bearing in mind

that weather conditions (ambient humidity) have a considerable effect on the preparation of espresso
coffee. Increase the coarseness of the ground coffee when ambient humidity increases and decrease it
when the humidity decreases.

• Have the state of wear of the grinders checked from time to time by authorised technical service person-

nel, bearing in mind that the flat grinding wheels cannot grind more than 300-600 kg of coffee beans
before becoming useless, while the limit for conical ones is 600-1200 kg.



Remember that both grind-

ers must be replaced, i.e. both the fixed and the moving grinder, since replacement of one only would
inevitably cause malfunctioning of the grinder-dispenser. Replacement must be carried out by authorised
technical service personnel.

• Clean the grinder-dispenser and its components from time to time, particularly the hopper and the dispenser.
• In case of prolonged idle periods (holidays, seasonal shutdowns, etc.), empty the hopper and the dis-

penser completely and carefully clean every part of the grinder-dispenser.
