1) This operating manual is an integral and essential part of the product and must be supplied to users. Users are asked to read the enclosed warnings and cautions carefully, as they provide valuable information concerning safety during

English

installation, operation and maintenance. This manual must be kept in a safe place and be available for consultation to new and experienced users alike.

2) Ensure product integrity by inspecting the packaging, making sure it presents no signs of damage which might have affected the enclosed machine.

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) Installation must be performed according to local electrical and plumbing codes and regulations. Installation must also comply to manufacturer instructions, and must be performed by Tuali¿ed and authorized personnel.

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 personnel to use this device.

13) Before carrying out any maintenance and/or cleaning operation, 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 the instructions contained in this manual only.

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 quali¿ed 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) <ou should plan to make use of a speci¿c 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.

7) Incorrect installation may cause injury/damage 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 reTuirement. Ensure Tuali¿ed 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.

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.

11) This device must be used exclusively for the functions it has been designed and built for. Any other application is inappropriate and dangerous.

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 quali¿ed professionals only.

WARNING

THIS EQUIPMENT MUST BE INSTALLED TO COMPLY WITH THE APPLICABLE FEDERAL, STATE, OR LOCAL PLUMBING CODES

The manufacturer shall not be held responsible for any damages caused by improper and/or irrational use.

General Description

The machine is built in a 3 group version and is essentially

omposed of the following parts

1) Steam Boiler (produces steam and hot water

English

2) 3 Coffee (“saturation”) boilers

3) Brewing groups

4) Exterior Cover Water pump/s

Description of the various parts

team Boile

The Steam Boiler consists of a cylindrical tank made of AISI 300 series stainless steel. Each unit is subject 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

ower ratings according to the number of groups installed

3 groups11 liters 4

overs are installed at either end of the cylindrical tank and on one of them there is housing for the water heating element, which allows the steam boiler to reach operating pressure within approximately 25 minutes. Operating pressure is maintained by temperature probe. The steam boiler has various ¿ttings

sed for safety devices, for supplying hot water and steam,

and for the heating element.

offee Boile

The Coffee Boiler consists of a cylindrical tank made of AISI

series stainless steel. Each unit is subject to a hydraulic test, at a pressure of 18 bar, and has an operating pressure of 9 bar. The following is a list of effective volume and power

atings according to the number of groups installed

3 groups - 3 x 1,3 liters 3 x

overs are installed at either end of the cylindrical tank

and on one of them there is housing for the water heating

lements. The temperature of the coffee boiler is maintained by an electronic temperature controller accuracy of 0.2°C. The brewing groups are installed on the

iler.

Brewing Group

They consist of precision casting made of stainless steel. The brewing group accepts the porta¿lter used to hold the ground

ee; the water Àows through the brewing group, through the

orta¿lter basket, through the porta¿lter spout, and into the

Exterior Cove

It consists of a stainless sheet steel body. The structure has been the object of speci¿c studies to provide good aesthetics,

ower ergonometric costs for the operator and reduce the

hance of damage to a minimum.

ater 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

eeds to be replenished.

ound Pressure

The weighted sound pressure level of the machine is lower than 70dBA.
