User manual GAGGIA E90

[. . . ] By carefully following the instructions contained in this manual you will be sure to appreciate the quality of our machine. Please therefore carefully read the instructions of use contained in this manual, which comply with essential safety regulations. Prima della messa in funzione, leggere attentamente il manuale di istruzioni Carefully read the following instruction booklet before starting up the machine. Togliere l'alimentazione elettrica prima di asportare le protezioni Carefully turn off the electrical supply before removing the protections Achtung! [. . . ] Then check the pressure on the pump gauge (11) putting a unit into operation with filter holder engaged filled with ground, dosed and pressed coffee in order to achieve an effective working pressure of 8/9 atm. Should re-calibration of the pump pressure be necessary this operation should be undertaken as indicated in paragraph 6. The machine is fitted with a gigleur ( 1 per unit) with a clearance of 0. 2 gigleurs are also included with the machine (complete with seals) with a clearance of 0. The pressure switch shown in the figure acts to keep the boiler pressure constant by engaging or de-activating the electrical heating resistance. 3 bar during the initial machine testing stage, but should a different working pressure be required, it is possible to vary the operational field of the pressure switch using the regulation screw (U); pressure reduction results in a reduction in temperature, whilst increasing the pressure will also increase the water temperature. The regulation direction is shown in the figure and on the pressure switch itself. 1 atm for every complete screw turn, When the machine is new the filter-holder sump may not be aligned (perpendicular to the machine itself) as shown in the figure at the side, however this does not effect the efficient function of the same. After a short period of use the sump will gradually settle into a correct position. B = Position of closed filter holder with machine after a short period of use. Warning: Disconnect the electricity supply before undertaking this operation. These packings may be used in the event of difficulty with insertion of the filter holder. Depending on the quantity of coffee ground, the appropriate filter must be as shown below to avoid that, once the coffee has dripped out, the leftover powder remains attached to the nozzle. Insert the filter holder into the unit filled with regularly ground, dosed and pressed coffee. Switch on the unit switch (E90) (17) or the unit control keyboard (D90) (16) and read the pressure on the pump pressure gauge (11). the new impulse value of the measure is thereby memorized on the EPROM. Both the solenoid valve and the pump are de-activated thereby suspending product delivery and all the keyboard leds go out. To proceed with a new programming operation of other coffee measures T2-T3T4 (providing that the programming time out time of 30 sec is not exceeded) simply repeat the same operations with the same sequence as undertaken for key T1. Wait until the pre-infusion function is complete before stopping delivery in progress. NOTE: During the programming of a unit the function of the other units is deactivated as well as tea dispensing. To programme the other units, press the specific programming key of each unit and carry out the same operations as undertaken on unit 1. In this case any variations in the measures are activated only on the unit on which one is actually working. [. . . ] 3 and allow the salted water to drain out of pipe F until the water is fresh. NB: These regeneration instructions are valid only providing the purifier is as that indicated in the figures. The machine is set up for being supplied with methane gas (G20), this means that the gas injector (O) and the gas regulator (N) are calibrated for methane gas. For operation with GPL gas (liquid gas G30) or town gas, the gas injector (O) must be replaced with the injector enclosed with the machine (see gas injector table). [. . . ]
