The electric plant must be provided with the following safety devices: - efficient earth connection; - section of conductors suitable for absorption capacity - efficient earth leakage protection circuit breaker. ● Install the machine on a water repellent surface (laminate, steel, ceramic, etc.) away from heat sources (oven, cooking stove, fireplace, etc.) and in conditions in which the temperature may not go below 5°C. KEEP WARM. ● Do not leave the machine exposed to atmosphe- ric agents or place them in damp rooms such as bathrooms. ● Do not obstruct the suction or dispersion grilles and do not cover with cloths, etc. ● Keep the packed machine in a dry place, not exposed to atmospheric agents and in conditions in which the temperature does not go below 5°C. Do not stack more than three items of the same kind. Do not place heavy items on the packa- ging. ● In an emergency, such as the breaking out of a fire, unusual noise, overheating, etc., take immediate action, disconnecting the power and closing gas and water taps. ● Only use original spare parts in order to avoid compromising the safety and proper functioning of the machine. Erroneous installation can cause damage to people, animals and things for which the manufacturer cannot be considered respon- sible44

The machines in the EPOCA series have been desi- gned to prepare express coffee and hot beverages. A positive-displacement pump inside the machine powers the heater in which the water is heated. By pressing the appropriate buttons, water is supplied to the spouts in the form of hot water or steam, ac- cording to needs. The water to be used for the beverages is supplied directly by the water supply, pressurized by the pump and immediately heated by the steam produced by the boiler. 2.1. Specifications and composition The machine is composed of a steel carrying struc- ture on which the mechanical and electrical compo- nents are fitted. These are completely covered with panels made of painted polyurethane and stainless steel. The beverages are dispensed at the front of the machine, where all the buttons, control devices and dispensers are to be found. There is a cup-warming plate on the top of the ma- chine.

It cannot be used for heating liquids or grinding any other kind of product that could damage and pollute it. The manufacturer cannot be held responsible for damage to people or things caused by unsuitable, erroneous or irrational use.

5.1. Packaging The machine is delivered in a strong cardboard box with internal protection. The packaging bears symbols which must be obser- ved during handling and stocking of the item. Always keep the package in a vertical position during transport. Do not turn it over or lay it on its side and avoid bumping and exposure to atmospheric agents. 5.2. Inspection on receipt Check that the machine received corresponds to the one indicated on the delivery note, including any accessories. Check that it has not been damaged during transport and, if so, inform the forwarder and our customer service office immediately. The packing elements (plastic bags, expan- ded polystyrene, nails, cardboard, etc.) must not be left within reach of children as they are potential sources of danger.

The machine have been designed, manufactured and protected to be used to make express coffee and hot beverages (tea, cappuccino, etc.). Any other use is to be considered unsuitable and therefore dangerous. The manufacturer cannot be held respon- sible for any damage caused to people or things due to unsuitable, erroneous or irrational use of the machine. The operator must always follow the indications con- tained in this manual. In the case of a failure or if the machine is not working properly, switch it off and do not attempt any direct repair. Refer exclusively to a service centre. You’ll find all the technical data on electric connection, on the machine identification label Fig. 1.46 6.1. Connections to be made by the user. Hook-up must be carried out by qualified personnel in full accordance with federal, state and local regulations.

6.1.1. Water supply (Fig.6)

This equipment is to be installed to comply with the applicable federal, state or local plumbing codes. Connections must be installed close to the machine. ● Water drainage pipe 1, having a minimum internal diameter of 30 mm, equipped with a water-trap accessible for inspection. ● Water supply pipe 2, with a 3/8"G cut-off tap. Make sure that the maximum supply pressu- re does not exceed 6.5 bar; otherwise, install a pressure reducer.

6.1.2. Electric supply

The machine is supplied ready for connection according to the required electrical specifications. Before connecting the machine ensure that the plate details comply with those of the electric distribution network. The electrical connection cable must be directly connected to the connection provided according to current legislation. Ensure that the earthing system is efficient and in compliance with current legal re- quirements. The earthing system and the lightening protection system must be realized in accordance with the provisions of current legislation. For the supply network use a cable in compliance with standards with protective conductor (earthing wire). For three-phase power use a cable with 5 conductors ( 3 phases + neutral + earth). For single phase power supply use a cable with 3 conductors (phase + neutral + earth). In both cases it is necessary to provide an automatic differential switch (Fig. 6) at the start of the power cable, complete with magnetic release elements in accordance with the identification plate details (Fig. 1). The contacts must have an opening of equal or over 3 mm and with dispersed current protection of 30 mA. Remember that each machine must be fitted with its own safety elements.

Should the power supply cable be damaged it is to be replaced by the manufacturer or by its technical assistance service or by person with equivalent qualification, in order to pre- vent any risks.

The appliance is only to be installed in lo- cations where use and maintenance is restricted to trained personnel. The machines are fitted with height adjustable feet. The support surface shall be levelled, dry, smooth, steady and stable and at such a height that the cup- warming surface is at over 150 cm from ground. Do not use water jets or install where water jets are used. In order to guarantee normal operation, the machine must be installed in areas that the environmental temperature is between +5°C ÷ +32°C end humidity of not over 70%. It does not need to be anchored to the surface and it does not require any technical operations to dampen vibrations in order to operate properly. It is recommended to leave the area around the ma- chine free to facilitate its use and the performance of any maintenance operations. If the machine is wet or very damp, wait until it is completely dry before installing or using it. It is always necessary to request an accurate control to qualified service people in order to find any possible damage to the electric components. Reserve an area near the machine for the installa- tion of the coffee grinding and dosage machine (see relevant documentation). The machine is usually equipped with a water sof- tener, type DP2 or DP4, which must be connected by the user in compliance with the laws in force. Should a different softener be installed, refer to the documentation of the relevant product. A dreg drawer should be fitted by the installer.47 6.2.

The machine has a top shelf on which the cups are kept and heated, ready for use. This is very important to obtain good coffee as the pre-warmed cup stops the coffee from growing cold too quickly. 8.1. Preparing coffee ● Unclamp the filter-holder from the dispensing unit and knock any grouts out into the drawer espe- cially provided for this purpose, taking care not to damage the rim of the filter. ● Use the filter for 1 or 2 coffees, according to need. ● Fill the filter with the measure of coffee, level it off and press it down gently with the presser. ● Remove any ground coffee that has stuck to the rim of the filter while pressing. If ground coffee is left on the rim of the filter, a leaktight seal is not ensured, with consequent leaking of water and coffee grounds. ● Lock the filter-holder into the dispensing unit firmly to obtain a leaktight seal. ● Place the cups under the spouts and start pouring using control 3 - 4 or button panel 5 according to model (Fig.7). ● When the coffee has been poured, leave the filter- holder attached to the dispensing unit until the next coffee is required. When pouring, beware of the hot parts of the machine, especially the coffee dispensing units, the steam and hot water spouts. Do not put your hands for any reason under the units and the spouts when they are operating. The grinding of the coffee beans is of fundamental importance to the making of good coffee, and the granular texture of the resulting grounds should be such that it takes 25-30 seconds to produce the beverage. If the coffee is ground too coardsely the coffee will be pale in colour and weak in flavour, with only a very small amount of white cream, and if the grounds are too fine, the coffee will be dark with no cream. Good coffee can only be made if the beans are freshly and uniformly ground (only possible when the blades of the coffee grinder are sharp) and are then measured out into the correct quantities (roughly 6 grams per measure). The importance of freshly ground coffee beans is due to the fact that once ground, they rapidly lose their aromatic qualities, and fats present in the beans go rancid.49 8.2. Preparing cappuccino (Fig.8) ● Make cup of cappuccino with the express coffee. ● Use a high and narrow jug, half-filled with milk. ● Place the jug under the spout so that the nozzle touches the bottom. ● Turn on the steam tap and lower the jug so that the nozzle is almost at the surface of the milk. ● Continuously move the jug up and down so that the nozzle moves in and out of the milk, causing it to froth. ● Turn off the steam tap and pour the milk into the cup. Immediately after carrying out this operation, clean the spout with a sponge or a clean cloth so that the milk does not dry on it. Be careful as the spout is hot and may burn your hand. 8.3. Heating a beverage ● Immerse the steam spout into the liquid to be heated. ● Gradually turn on the steam tap 7 Fig.7; the steam that bursts in the liquid heats it to the desired tem- perature. ● Turn off the steam tap when the desired tempera- ture has been reached. Immediately after carrying out this operation, clean the spout with a sponge or clean cloth. Be careful as the spout is hot and may burn your hand. 8.4. Preparing tea, camomile, etc. ● Place the jug under the hot water spout and turn the water tap 6 (Fig.7). When the desired quantity has been obtained, turn off the tap. ● Add the beverage desired. When purified water is used, these beverages often assume a darker colour. Should the user prefer a lighter coloured drink, draw fresh water from an ordinary tap and proceed with the heating phase as described in point 8.3.

9. ADJUSTMENT AND SETTING OF THE

DOSE (where available) 9.1. Models DE It is possible to adjust the dose of coffee dispensed DE models.

9.1.1. Adjusting the dose

The coffee dose adjustments are made by acting on the group keyboads with machine at rated pres- sure. 1 Press the button E on any button panel and hold it down for 8-10 seconds until water stops flowing from the dispensing unit and the led of the conti- nuons button on the first button panel on the left begins flashing. 2 It is necessary to act as to make 1 or 2 cups in or- der to reach the correct coffee amount adjustment in the cup. 3 Put the filter-holder (with ground coffee) on the left unit and the cup under the spout. 4 Operate the selected button (i.e. button A for one small cup). 5 One the required coffee amount in the cup has been reached, press the stop button E. Coffe will stop pouring and the microprocessor will store the dose. 6 Press the continuous button E again; the led will go out and the machine will store the new quantity. 7 Make the coffee and check the cup amount in order to check that programming is correct. If some doses have to be changed (B-C-D), once at point 5 repeat the instructions in points 3-4-5 for each dose, remembering to use the filter-holder with relevant filter and freshly ground coffee. Then carry out point 6 and repeat point 7 to check all changed doses. If all units are to be programmed with the same doses, the selection of coffee doses is finished. If the dosage of another unit is to be changed (1-2-3-4 doses), pro- ceed as indicated in the above-mentioned point 1-7, using only the button panel of the selected unit.50 Cleaning the filters and delivery heads (Fig.9) Operation to be carried out when the machine is off and cold. ● Prepare a solution of 4 sachets of detergent powder Code 69000124 dissolved in a litre of boiling water in a stainless steel, plastic or glass recipient (NOT ALUMINIUM OR IRON). ● Remove the filters and immerse them with the filter holders in the prepared solution, leaving them for at least 10/20 minutes (all night is better). ● Remove them from the container and rinse them thoroughly in running water. Tank cleaning (Fig.10) ● Remove the cup-stand grille 1 (Fig.10) and clean. ● Check and clean the drainage sump 3 (Fig.11), removing any sludge with the help of a spoon. 10.2. Weekly Operations to be carried out with the machine operative and under pressure. ● Place the supplied blind filter in the filter-holder, put in a spoonful of detergent in powder for coffee machines and fit the filter-holder in the unit to be cleaned. ● Press the coffee dispensing button and draw water for approx. 30 seconds. ● Stop and start dispensing several times until clean water comes out of the discharge unit tube. ● Remove the filter-holder, take out the blind filter and insert a normal one.Replace the filter-holder on the unit and rinse by drawing water several times. ● Make a coffee to eliminate any unpleasant taste.

Maintenance operations have to be carried out when the machine is off and cold and the plug is disconnected. Some particular operations have to be effected when the machine is operating. Do not clean the machine by using metal or abrasive devices, such as steel wool, metal brushes, needles, etc. or general detergents (alcohol, solvents, etc.) When necessary, use special detergents for coffee machines that can be bought in specialized service centres. 10.1. Daily (Fig.9) Use a clean cloth or sponge that does not leave hairs or fluff (preferably cotton or linen). ● Carefully clean the outside surface, following the grain of the satin finish on the parts in stainless steel. ● Clean the steam and hot water spouts, check that the nozzles are not encrusted (if they become encrusted, be careful not to deform or damage them). ● Clean the spray units and the seals under the ca- sing of the delivery units using the special brush supplied ● Remove the filter-holders of the machine and re- move the filters and the clamp which secures the filter, use a brush to remove any coffee deposits and rinse with hot water in order to dissolve any grease deposits.

10.3.1. Renewal of water in the boiler

To be carried out only by qualified personnel. ● Turn off the machine and wait for the pressure in the boiler to diminish (gauge needl on “0”). ● Using a spanner firmly hold 1 the outlet pipe 2 Fig.11 situated about the drainage sump while loosening the hexagonal sealing screw 4 by 3 turns at the most. ● Drain off the water and tighten the screw 4. ● Refill the boiler (paragraph 7.3.). 10.3. Periodical maintenance Operation to be carried out with the machine under pressure. ● Discharge the water from the boiler (about four litres) with hot water delivery switch 6. ● Wait until the machine has returned to heat equi- librium before reuse.51

11. STOPPING THE MACHINE

A - Temporary stop ● Carry out cleaning and maintenance operations. ● Wind up the cable and fasten it to the machine with sticky tape. ● Cover the machine and place it in a dry room. Do not leave it exposed to atmospheric agents and do not allow it to be touched by children or unift persons. To disconnect from the main power supply, consult qualified personnel. B - Definitive stop ● Besides carrying out the operations necessary for a temporary stop, cut off the cable, pack the ma- chine in cardboard, polystyrene or other packing material and consign it to firms authorized for its disposal or to second-hand goods dealers.
