16G.4.2 Adjusting the expansion valve1 group modelThe High pressure valve is located on the right side of the appliance: it isnecessary to dismantle the right side.The valve is set above the pump; its adjusted pressure must just be greaterthan the water network pressure. Recommended value: 7 bar [0.7 MPa] to 8 bar[0.8 MPa] (green scale of the pressure gauge).• If the valve opens ABOVE 8 bar [0.8 MPa]: LOOSEN• If the valve opens BELOW 7 bar [0.7MPa]: TIGHTENUse the tool reference OU003; after the adjustment, do not forget to blockthe counter nut.model 2 groups or moreThe HP valve is located in the lower part at the left rear of the appliance: it isnecessary to dismantle the left side. The valve must open at about 13 bar [1.3MPa] (green scale of the pressure gauge).• If the valve opens ABOVE 13 bar [1.3 MPa] LOOSEN• If the valve opens BELOW 13 bar [1.3 MPa] TIGHTENUse the tool reference OU003; after the adjustment, do not forget to blockthe counter nut.G.4.3 Adjusting the pump pressureDuring infusion, the pressure must be 9 to 10 bar [0.9 MPa et 1 MPa] (gaugegreen scale).1 group model : The pump is located in the left side.model 2 groups or more : The pump is located in the right side.• SCREW IN to INCREASE the pressure• UNSCREW to DECREASE the pressureG.4.4 Adjusting the coffee grindingWait until the machine has reached the set temperature 0.9 bar [0.09 MPa] and 1 bar [0.1 MPa]. It is the finesse of the grinding whichdetermines the time for passing the hot water through the dose. This time is usually monitored by using the two-cup filter with twodoses of coffee. Average passing time for 2 cups (6 to 7 cl. per cup): 30 to 35 seconds.NOTE!To obtain a good result, use at least 6 g. of (good) ground coffee per cup.• If the infusion time is shorter, reduce the grinding.• If the infusion time is too long, increase the grinding.G.4.5 SoftenerTest the water hardness of the network and refer to the technical documentation of the water softener used for optimum adjustment.A softener must be changed every 1 year, even if it does not reach the end of its filtering capacity.H OPERATINGNOTE!When the machine has been installed and thehydraulic, electrical connections have been carriedout by a qualified installer.WARNINGDo not forget to open the watertap supplying the machine.H.1 Switching onFig. 1 Main switch1.
