The symbol of the crossed large rubbish container that is present on the machine points out that the product at the end of its life cycle must be collected separately from the other wastes. The user for this reason will have to give the equipment that got to its life cycle to the suitable separate waste collection centers of elec- tronic and electrotechnical wastes, or to give it back to the seller or dealer when buying a new equipment of equivalent type, in terms of one to one. The suitable separate waste collection for the follow- ing sending of the disused equipment to recycling, the dealing or handling and compatible environment disposal con- tributes to avoid possible negative ef- fects on the environment and on the peo- ple’s health and helps the recycling of the materials the machine is composed of. The user’s illegal disposal of the product implies the application of administrative fines as stated in Law Decree n.22/1997” (article 50 and followings of the Law De- cree n.22/1997).44

When contacting the manufacturer, Victo- ria Arduino for any reason, always quote the machine serial number. The machine is transported on pallets containing several machines inside boxes secured to the pal- let by straps. Before performing any trans- port or handling operation, the operator must wear safety gloves and footwear, as well as overalls with elastics. Pallets must be transported using an adequate liing mechanism (fork-li truck type).

COLLISION OR CRUSHING HAZARD

During the entire handling operation, the operator must make sure no one or noth- ing is inside the operating area. Slowly li the pallet to about 30 cm from the ground and move to the loading area. Aer mak- ing sure there are no obstacles, persons or things, proceed with loading. Once at destination, always using an adequate li- ing mechanism (e.g. fork-li), aer making sure there is no one or nothing within the unloading area, lower the pallet to about 30 cm from the ground and transport it to the storage area.

COLLISION OR CRUSHING HAZARD

Before performing the following opera- tion, make sure the load is in place and is not likely to fall when the straps are cut. The operator, wearing safety gloves and footwear, must now cut the straps and store the product. To perform this opera- tion, check the technical characteristics of the product to determine the weight of the machine to be stored and take conse- quent precautions. POLLUTION DANGER Once the machine has been freed of the pallet or container, do not discard these in the environment - pollution hazard.

AND PRELIMINARY OPERATIONS Aer unpacking, assess that the machine and its accessories unit are complete, then proceed as follows: ȗ Place the machine on a flat surface; ȗ Level the machine through the adjustable feet;

In the preliminary stage, it is advisable to install a soener (A) on the external part of the hydraulic system, and then a mesh filter (B). In this way impurities like sand, particles of calcium, rust etc. will not damage the delicate graphite surfaces and durability will be guaranteed. Following these operations, connect the hydraulic systems (see Fig. 06). WARNING Recommended water mains pressure is [2.3] bar. WARNING Avoid throttling in the connecting tubes. Check the drain pipe (3) eliminates waste.48

NOTE At the beginning of the daily activity and in case of breaks longer than 8 hours, it is necessary to change 100% of water in the circuits by means of the proper dis- pensers. NOTE In case of continuous services, carry out the above changes on a weekly basis.

KEY A. Water soener B. Mesh filter C. Drainage system Ø 50 mm NOTE For a correct functioning of the machine the water works pressure must not ex- ceed 4 bars. Otherwise install a pressure reducer upstream of the soener; the in- ternal diameter of water entrance tube must not be less than 6mm (⅜”).

SHORT CIRCUIT HAZARD

The machine must always be protected by an automatic unipolar switch of suit- able power with contact openings of equal distance or more than 3mm. Victo- ria Arduino cannot be held liable for any damage to people or things due to non observance of the safety prescriptions. Prior to connecting the machine to the electrical mains, assess that the voltage shown on the machine’s data plate cor- responds with that of the mains.

PROCEDURE All models are equipped with a level gauge to keep the water level inside the boiler constant. When using the machine for the first time or by emptying the boiler for main- tenance, make sure there is water in the circuit to prevent the electrical resistor from damaging and activating the elec- tronic protection. When starting the machine for the first time, it shows “installation, press enter”. ȗ By pressing ENTER , the pump starts automatic filling of boilers.

ȗ When water comes out from dispensing group, press ENTER again to stop the filling phase of the hydraulic system;
