Safe electrical operation of this device will be achieved only when the connection to the power outlet has been completed correctly and in observance of current safety regulations, and particularly by grounding the unit very carefully. Make sure grounding has been done correctly as it represents a fundamental safety requirement and, in case of doubt, do not hesitate to have qualified personnel check such connection.

Furthermore, you must ensure that the capacity of the available electrical system is suitable for the maximum power consumption indicated on the rating plate; make sure also that electrical cables are of a suitable size.

We do not recommend using adapters, multiple plugs and/or extension cords. If you cannot avoid using them, make sure that they are exclusively of the kind which conforms to current safety regulations, being careful not to exceed the power and current ratings indicated on such adapters and extension cords.

6)This device must be used exclusively for the functions it has been designed and built for. Any other application is inappropriate and dangerous. The manufacturer shall not be held responsible for any damages caused by improper and irrational use.

7)Using any electrical device requires that certain fundamental rules be observed.

In particular:

General description

The model EE machine is built in the 1, 2, 3, and 4 group versions and is essentially composed of the following parts:

1.Water boiler (produces steam and hot water);

2.Coffee (“saturation”) boiler;

3.Brewing groups;

4.Cover;

5.Motor pump;

6.Water purifier.

Description of the various parts

1. Water Boiler

It consists of a cylindrical tank, of varying length according to the number of coffee groups, which is made of Aisi 304 stainless steel. Each unit is subjected to a hydraulic test, at a pressure of 3 bar, and has an operating pressure of 1.5 bar. In the following, you will find a list of effective volumes and power ratings according to the number of groups installed:

1 group	3,5 litres	1300 Watts
2 groups	7 litres	2000 Watts
3 groups	11 litres	3000 Watts
4 groups	15 litres	3800 Watts

3. Brewing Groups

They consist of a die-cast block made of nickel-plated brass, on which to install the filter-holder handle used to hold the ground coffee; the espresso flows from the block, through a spout, into the cup(s) after the brewing button has been pressed.

4. Cover

It consists of a painted and stainless sheet steel body. The structure has been the object of specific studies to provide good aesthetics, to lower ergonometric costs for the operator and to reduce the chance of damage to a minimum.

5. Motor Pump

The pump, which is of the “positive-displacement” type, is installed on the water supply tubing and is set-up to operate anytime the coffee groups are activated, and through an electric level gauge whenever the water boiler needs to be replenished.

6. Water Purifier

It is of the “ion exchange” resin type, for water softening purposes. Resins must be regenerated weekly according to the instructions and the diagrams shown on the labels affixed to the purifiers themselves. See Chapter 6.

Covers are installed at either end of the cylindrical tank and on one of them there is a housing for the water heating and vapourizing electrical elements, which allow reaching operating pressure within 25’ approximately. Operating pressure is maintained by a manostat. The water boiler has various fittings used for safety devices, for supplying hot water and steam, and for the power supply.

2. Coffee Boiler

Each unit is subjected to a hydraulic test, at a pressure of 16 bar, and has an operating pressure of 9 bar. In the following, you will find a list of effective volumes and power ratings according to the number of groups installed:

1 group	1.8 litres	1000	Watts
2 groups	3.4 litres	1400	Watts
3 groups	5.0 litres	1600	Watts
4 groups	3.4 + 3.4 litres	1400	+ 1400 Watts

(2 boilers installed)

It consists of a cylindrical tank, of varying length according to the number of coffee groups, which is made of Aisi 304 stainless steel.

Covers are installed at either end of the cylindrical tank and on one of them there is a housing for the water heating and vapourizing electrical elements, regulated by a precision thermostat with a dT of ± 1°C wich keeps the water temperature constant. This temperature can be adjusted to reach optimal temperature according to the type of coffee blend being used. The groups are installed on the boiler.

General Description

The model AV machine is built in the 1, 2, 3, and 4 group versions and is essentially composed of the same parts as model EE.

This model differs from model EE in that it allows the operator to choose four different quantities of water for brewing coffee. Each group, therefore, is provided with a 5 button control panel, allowing a combination of:

-a quantity of water for one normal (short) coffee;

-a quantity of water for one tall coffee;

-a quantity of water for two normal coffees;

-a quantity of water for two tall coffees.

The fifth button is used to program the other ones, as we shall see later, and as an on-off switch for continuous brewing.
