3) Check the machine’s integrity after having carefully removed the packaging.

Note:

In case of doubt, do not go on any further and contact your dealer or retailer immediately. They will send out specialized personnel authorized to perform service on the espresso machine.

4) Packaging (boxes, plastic bags, foam parts and whatever else) must not be left around within easy reach of children, due to the potential danger it represents, nor be discarded in the environment.

5) Check to see that data on the rating plate corresponds to those of the main electrical supply which the machine will be hooked up to.

6) The installation must be performed according to local electrical and plumbing codes and regulations. The installation also must comply to the manufacturer’s instructions, and must be performed by qualified and authorized personnel.

7) Incorrect installation may cause for injury/damages to people, animals or objects, for which the manufacturer shall not be held responsible.

8) 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 all local, national, and international electrical codes and safety regulations, and particularly by grounding the unit. Make sure grounding has been done properly as it represents a fundamental safety requirement. Ensure qualified personnel check such connection.

9) Furthermore, you must ensure that the capacity of the available electrical system is suitable for the maximum power consumption indicated on the espresso machine.

This device must be used exclusively for the functions it

11) 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/or irrational use.

12) Using any electrical device requires that certain fundamental rules be observed. In particular:

- do not touch the device with wet or humid hands and feet;

- do not use the device while having no shoes on your feet;

- do not use extension cords in bath or shower rooms;

- do not unplug the device from the power outlet by pulling on the power supply cable;

- do not expose the device to atmospheric agents (rain, sun, etc.);

- do not allow children or untrained people to use this device.

13) Before carrying out any maintenance and/or cleaning operations, turn the main switch, which is located on the front left of the machine, to the “0” or OFF position, and disconnect the machine from the electrical network by unplugging the cord or by switching off the relative circuit breaker. For any cleaning operation, follow exclusively the instructions contained in this manual.

14) In case the machine is operating in a faulty manner or breaks down, disconnect it from the electrical network (as described in the preceding point) and close the water supply valve. Do not attempt to repair it. Contact a qualified and authorized professional to perform any repair. Any repairs must be performed exclusively by the manufacturer or by an authorized centre using only original parts. Non compliance with the above could compromise the safe operation of the machine.

15) You should plan to make use of an omnipolar connector during installation, as required by local, national, and international electrical codes and regulations.

16) In order to avoid dangerous overheating problems, it is recommended that the power supply cable be fully unfurled.

17) Do not obstruct air intake and exhaust grilles and, in particular, do not cover the cup warmer tray with cloths or other items.

18) The machine’s power supply cable must not be replaced by users. In case the power supply cable becomes damaged, shut off the machine and disconnect the machine from the electctrical network by switching off the relative circuit breaker and close off the water supply; to replace the power supply cord, contact qualified professionals exclusively.

10) 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 local, national, and international electrical codes and safety regulations, being careful not to exceed the power and current ratings indicated on such adapters and extension cords.

2) General Description

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

1) Steam Boiler (produces steam and hot water)

English

2) Coffee (“saturation”) boiler

3) Brewing groups

4) Exterior Cover

5) Water pump

3) Description of the various parts

• Steam Boiler

The Steam Boiler consists of a cylindrical tank, of varying length according to the number of coffee groups, which is made of AISI 300 series stainless steel. Each unit is subjected to a hydraulic test, at a pressure of 6 bar, and has an operating pressure of 1.3-1.5 bar. The following is a list of effective volumes and power ratings according to the number of groups installed:

2 groups 7.0 liters 2000 or 3000 Watts 3 groups 11 liters 3000 or 4000 Watts 4 groups 14,5 liters 3000/3800 or 5000 Watts

Covers are installed at either end of the cylindrical tank and on one of them there is a housing for the water heating element, which allows the steam boiler to operating pressure within approximate 25 minutes. Operating pressure is maintained by a pressure switch or a temperature probe. The steam boiler has various fittings used for safety devices, for supplying hot water and steam,, and for the heating element.

• Exterior Cover

It consists of a stainless sheet steel body for the GB/5 and painted plastic for FB/80. 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.

• Water Pump

The water pump, is a differential pressure, “positivedisplacement” type 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 steam boiler needs to be replenished.

The Coffee Boiler and Steam Boiler contain water at elevated temperature.

Water temperature over 125 F / 52 can cause severe burns instantly or

• Coffee Boiler

The Coffee Boiler consists of a cylindrical tank, of varying length according to the number of coffee groups, which is made of AISI 300 series stainless steel.

Each unit is

subjected to a hydraulic test, at a pressure of 18 bar, and has an operating pressure of 9 bar. The following, table is a list of effective volumes and power ratings according to the number of groups installed:

2 groups 3.4 liters 1400 Watts 3 groups 5.0 liters 1600 or 1900 Watts 4 groups 3.4 + 3.4 liters 1400 + 1400 Watts

(2 Boilers Installed)

Covers are installed at either end of the cylindrical tank and on one of them there is a housing for the water heating elements. The temperature of the coffee boiler is maintained by an electronic temperature controller (PID capable) with an accuracy of 0.2°C. The brewing groups are installed on the boiler.

• Brewing Groups

They consist of a precision casting made of stainless steel. The brewing group accepts the portafilter used to hold the ground coffee; the espresso flows through the brewing group, through the portafilter basket, through the portafilter spout, and into the cup(s) after the brewing button has been pressed.
