[. . . ] 4) with all the information to refer to regarding the appliance, is situated inside the right or left side of the control panel, depending on the model. The appliances have been checked in accordance with the European norms below. Declaration of compliance The manufacturer declares that the appliances of their production are compliant with the above mentioned EEC norms and requires that installation be done observing the norms in force, particularly regarding the system for letting out fumes and air exchange. Gas Appliances Sturdy structure in steel placed on four feet which make it possible to regulate the height in the version with cabinet. [. . . ] If flexible piping is used, this must be in stainless steel and compliant with the norm. All the seals on the junction threads must be in guaranteed materials certified for use with gas. Before the installation of each single appliance it is necessary to install a cutoff cock for rapid interruption of the gas supply, placed in an easily accessible position in such a way as to make it possible to turn off the gas supply when the appliance is not being used. When the connection has been completed, the tightness must be checked by using a leak-finder spray. Electric connection Before connecting the appliance, it is necessary to check that the voltage of the power supply available corresponds to the voltage the appliance has been set for. In the event that they do not correspond, it is necessary to modify the connection as shown in the electric diagram, if voltage change is provided for. The junction boxes are situated behind the control panel of the top, is accessible by unscrewing the screws which fix the panel and removing it. Furthermore, the efficiency of the earth connection must be checked, and also that the earth conductor on the connecting side is longer than the other conductors, and that the connecting cable has a wire bunch adequate for the power absorbed by the appliance and is at least type H05 RN-F. In accordance with international rules, before installing the appliance a unipolar device must be installed with a contacts opening of at least 3mm which must not interrupt the YELLOW-GREEN earth wire. The device must be installed near the appliance, it must be approved and have adequate capacity for the absorption of the appliance (see technical features). 5) Connection to the water mains Connect the water inlet pipe to the mains, following the rules stipulated by the norms in force. Drainage connection The drainage pipe must not be connected directly to a common drain, but positioned over a reservoir, at a distance which does not allow it come into contact with the sides of the reservoir or with the water inside it, in order to avoid contaminating the food in the tub. Before proceeding to check the pressure, it is necessary to check the tightness of the gas installation up to the nozzle with a leak-finder spray to ensure that no damage has been done to the appliance during transportation. Then it is possible to proceed with checking the inlet pressure, which is done by means of a gauge for liquids , either a "U" gauge or an electronic gauge with a minimum definition of 0, 1 mbar. To carry out the reading, the screw (1) must be removed from the pressure outlet (2) and the rubber pipe of the gauge connected. Open the gas supply valve of the appliance, check the pressure output and close the valve. Remove the pipe of the gauge and put back the screws correctly into the pressure outlet. The pressure valve must be within the minimum and maximum values shown below: If the pressure reading is not within the limits of the table, find out the cause. After solving the problem, check the pressure again. Checking the power Normally, it is sufficient to check that the nozzles installed are the right ones and that the burners function properly. If desired, further check the power absorbed by using the "Volumetric Method". With the help of a chronometer and a counter, it is possible to read the volume of gas output to the appliance in time units. [. . . ] Before doing any kind of maintenance or repairs, make sure that the appliance is disconnected from the electric mains and that the gas cutoff valve is closed. The following maintenance operations must be carried out at least once a year by specialized personnel. Check for correct functioning of all control and safety devices; Check for correct ignition of burners and proper functioning at minimum; Check the tightness of the gas pipes; Check the condition of the power cable; The gas tap should be lubricated but this is a difficult operation and not very reliable; therefore it is advisable to substitute it; Before carrying out any substitutions, make sure that the appliance is disconnected from the electric mains and that the gas cutoff valve is closed. Safety cock To substitute the cock, it is necessary to remove the knobs and the control panel, then unscrew in sequence the pipe union of the piping which goes to the burner, the pipe union of the piping of the pilot burner, the thermocouple and finally, the pipe union of the ramp.
