A1. Residue liquid bucket

It collects all the residue liquids that the machine generates. It has a capacity of 8 litres.
When it reaches a determined level a float device is activated to put the machine out of order
until it is emptied.

A2. Coffee residue bucket

It collects the solid residue that the machine generates. It has a capacity for the residue of
7500 grams of ground and elaborated coffee beans.

A3. Infusion element

Made of resin, it is the element that the machine uses to make the espresso coffee.

Between the piston and its support there is a spring and a espacer that, depending how it is
placed, will vary the capacity of ground coffee the chamber will hold.

The spacer should be placed between the piston and its support when the dosage is set for 5
to 6.5 g of ground coffee. When the dosage is set for 7 to 8 g of ground coffee, the space
should be placed on the piston support.

The infusion element has moving parts that are activated by a 24 Vdc motor that moves a
crank which moves the coffee from the dosage element to the piston. At the same time it also
moves a lever that activates a micro switch; this indicates the position of the infusion element
to the control board.

At rest, the infusion element cannot move from its position as it is held by the piston. Before
extracting the piston the black extraction button (C7) should be pressed (with the machine
switched on). On pressing the extraction button the infusion element will position itself in the
coffee loading position. After this the two levers that hold it can be turned and it can be
removed with ease.

In the infusion element support there is another micro switch that deactivates when the
infusion element is removed. This way, the control board knows whether the infusion element
is correctly positioned or not.

To replace the infusion element into the machine it may be in any position and it does not
matter if it moves while out of the machine. It only needs to be replaced and the two holding
levers fixed. When the presence micro switch is activated, the infusion element motor will
position it correctly.

A4. Beaters

The mixing of the products with hot water from the boiler is done with these elements.

Technical characteristics:

Make of motor Mabuchi

Voltage 24 Vdc
Power 20 w
Speed 16 rpm
The EVs of the instant beverages are an important part of the beating process. They control
the hot water from the boiler to the beaters for the elaboration of the instant beverages.

They are fitted to a thermo compensated brass support that provides a constant temperature
by means of a tube through which hot water from the boiler flows. This circulation is produced
by convention; the water cools in the brass support and drops while the hot water from
the boiler enters at the top. This way, during the elaboration of the instant beverages, the
hot water that goes to the beaters does not suffer excessive temperature losses.

The working voltage of the EVs is 24 Vdc

Maximum pressure they accept is 15 Kg/cm²

A5. Ground coffee dosage element

Situated on the side of the grinder, its function is to measure the quantity of ground coffee for
each service, and later put a dose into the infusion element.

The principle function is based on a moving wall that the ground coffee moves and a micro
switch that is activated by the moving wall. On activating the micro switch, the grinder stops
and the EV drops the ground coffee into the infusion element.

A13. Button panel and display

These machines have an innovative system for the product selection buttons. The system is
based on capacitive detection. To request a product it is not necessary to actually press the
button, it is enough to put your finger near the button and the machine will detect its presence
and start the elaboration of the requested beverage. All the product selections have a red led
diode that lights when the machine is elaborating that beverage. There is a panel with a label
of all the available products in the machine between the Perspex protection and the circuit
board of the buttons.

On the circuit board there is also an alphanumeric display with two 16-character lines.

The panel with the product labels can be removed by pulling downwards. It is held
between two grooves on both sides of the circuit board so to replace it is necessary to
insert it in the grooves.

A14. Product door

Made of polycarbonate, its main purpose is to prevent the entry of insects into the machine. It
can be removed by removing the holding plate on the interior of the machine.

A15. Water inlet EV

It allows the entry of water from the mains to the cold water deposit. It works at 230 Vac.
This EV is only fitted to machines that are connected to the mains water supply.

unblock

It has a security block system for cases where, for lime scale or any solids from the main
water supply, the EV does not close properly. This system activates when the level in the
residue bucket is excessively high.

To unblock the EV, switch off the water pressure from the mains. If this is not possible, tap the
EV with a blunt object, for example an Allen key, on the inside of the hole on the top part of
the EV as shown in the photograph.
It you may also unblock the EV by tapping it with something like the handle of a screw driver.

A16. Volumetric counter

Its function is to measure the quantity of water that is pumped for the elaboration of the
espresso coffee.

A17. Water pump

This element has the job of pumping water from the cold water deposit to the hot water boiler;
the cold water pushes the hot water towards the EVs for the instant products or towards the
infusion element for making espresso coffee.

1ª 10012 - E 02 - 2006
 19

K1. By-pass
K2. Anti return valve

When an espresso coffee is elaborated, the water pressure needed is quite high to be able to
pass through the compressed ground coffee in the infusion element. This resistance the coffee
offers makes the water pressure in the boiler increase up to a pressure of 9 Kg/cm². At this
pressure the by-pass (2) opens allowing a small amount of water to return; sufficient to
prevent the water pressure from going over the 9 Kg/cm².

The by-pass is a small hole covered with a ball that is held in place by a spring. This spring
will hold a pressure of 9 Kg/cm², but over this pressure it compresses and allows the
water to pass.

The pressure of 9 Kg/cm² is considered the ideal for elaborating espresso coffee.

When the instant beverages are elaborated, there is no resistance offered and so during there
elaboration the water pump works at lower pressures than when elaborating espresso coffees.

Technical characteristics:

Voltage Pulsing 110 V

Power 70 w
Working pressure 8 Kg/cm²
Maximum pressure 12 Kg/cm²
The pump has an anti return valve that prevents the return of water from the boiler.

A18. Cold water deposit

Made of polypropylene, It has the capacity of 500 cc. It is at atmospheric pressure
and temperature. From this deposit is taken the water to elaborate the espresso coffee and
instant beverages.
The water level in the deposit is controlled by a float that activates a magnetic switch.

A19. Hot water boiler

The boiler works under pressure and has a capacity of 0.5 litres of water. The water for
elaborating espresso coffee and instant beverages is heated in this deposit.

L1. 1500 W heating element

L2. Security thermostat 120º C
L3. Temperature sensor (PTC)
L4. Triac
L5. Electrovalves

The boiler is made of brass and does not need any device to control the level of water as the
boiler fills automatically from the moment the machine is switched on. After this the water that
is used is replaced with water from the cold deposit so the boiler is always full.
There are three outlets; one through a 3-way EV for the elaboration of espresso coffee. This
EV has an outlet from the boiler, another goes to the infusion element, and the third that, at
rest, allows the infusion element to be at atmospheric pressure.

When the machine is in the espresso coffee making process, the third is closed while the
outlet from the boiler and the inlet to the infusion element are open to each other.

N1. 3rd closed

N2. To the infusion element
N3. From the boiler

When the machine finishes elaborating an espresso coffee, the EV goes to rest state and
closes the outlet from the boiler leaving the infusion element open to the third outlet. In this
way the water that did not pass through the coffee and was retained in the infusion element
goes out through the third outlet to the residue bucket.
The water recedes back from the infusion element towards the third outlet because of the
pressure it was submitted to by the pump in the infusion process.

P1. 3ª open
P2. Infusion element joined to atmospheric

The other two outlets are connected to the instant beverage EV. When the machine is at
rest, these outlets allow the circulation of water, through convection, between the boiler
and the brass support of the instant beverage EV. This way the support is thermo
compensated and the water that reaches the beaters is always at the correct temperature.

A20. Extractor

The steam and vapour that is generated by the beaters can reach the product containers and
if they become damp they form lumps in the powder. This consequently results in the
irregular extraction of the product. To avoid this, the extractor is used to remove the steam
and vapour
from the interior of the machine. It works on 230 Vac.

A22. Circuit boards

All the models in the City range have 5 circuit boards. The main module is the one that
provides the power supply to the other boards and takes the decisions for the correct working
of the machine. The other four boards control independently a determined number of elements
in the machine.

This model will only work when connected to a mains water supply with a minimum pressure of
2 kg/cm². The machine comes with a pressure regulator of 2 kg/cm² and this is the pressure
that all the instant beverages and the teas are elaborated.

The pressure of the regulator can be modified by lifting the cover and turning it to the left or
right. Once regulated, push down the cover again. The manometer will show the pressure you
have set.

The tea is infused in the same way as in an infusion group for the espresso coffee machines.
The tea that has been infused goes to the instant tea beater, once the whole infusion process
is finished, and then an electro-valve is opened to let the infusion go to the cup. With this
1ª 10012 - E 02 - 2006

method the infusion reaches the cup from a lesser height than the height of the outlet tube of
the infusion group, and thus avoiding bubbles in the tea.

3. INSTALLATION AND SWITCHING ON

3.1. UNPACKING

The power supply of the machine requires a socket, or another system, that allows its disconnection.

The method used must guarantee the complete disconnection of both poles.

Elemental safety requirements:

a) Never touch any mechanisms with wet hands or feet.

b) Never connect or use the machine barefoot.

c) Never pull on the flex to unplug the machine.

d) Never leave the machine exposed to the elements: sun, rain, snow, etc.

3.2. SWITCHING ON

Site the machine in its place and level it using the regulating feet.

3.2.1. Water connection

The machine can be used connected to the mains or with an autonomous water deposit. To
connect the machine to the mains use a ¾” male connection. The mains supply must provide
drinking water at a minimum of 5 litres/minute and a pressure of between 0.5 and 10 kg/cm².
For the Fresh brew model, the minimum pressure is 2 kg/cm².
The connection hose for the mains is not supplied with the machine.

 29

Models LE and LI are prepared for connection to the mains water supply in the factory,
so no additional parts are necessary.
However, for models ME and MI, it is necessary to add: an electro valve for the
mains connection, a cold water deposit, a water level gauge and the connection hoses.
The reference of this connection kit that includes this set is 41511891-0.

Depending on the quality of the water, hardness, chlorine, bleach, etc, the connection should be
complemented with a filter.

If the machine is fitted with a filter, the minimum water pressure should be 1 Kg/cm².

3.2.2. Electrical connection

The machine works with 230 Vac (50 Hz). The installation must have:

• An earthed socket

• A minimum power rating of 2500 w

• The installation site must have a breaker switch and a good earth connection

3.2.3. Connecting a Coin Validator (Ranges MI/ME)

The Tempo ME and Tempo MI models are factory prepared to install a coin validator, which can
be from Azkoyen or another manufacturer. The validator is not supplied with the machine.

The fitting of the validator is simple; it is clipped into the bracket.

The wiring loom for the validator is connected to JP8 on the MDP circuit board. The machine
only works with exact change.

3.2.5. Filling the product containers

To put products in the containers, you should lift the cover of the machine. Otherwise it is
necessary to remove the container from the machine.

After filling the containers for instant beverages, it is advised to request a

service of each as the first time it is used, only a small quantity of product is
served

Now the machine can be switched on.

3.2.6. Filling the hot water boiler

On connecting the machine the hot water boiler fills automatically. In the espresso coffee
machines the following process occur:

- The cold water deposit fills up, if it is empty.

- The volumetric counter is tested and the boiler is filled with the EVs closed. When the
counter stops spinning, the boiler is full. Then the instant product EVs open to let out
the air in the lines and boiler.

If the counter does not spin for 10 seconds while filling the boiler the
machine will go out of order as there is no water. To reset this state, just
switch the machine off and then back on
