G.4.2 Adjusting the expansion valve
1 group model
The High pressure valve is located on the right side of the appliance: it is
necessary to dismantle the right side.
The valve is set above the pump; its adjusted pressure must just be greater
than 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]: TIGHTEN
Use the tool reference OU003; after the adjustment, do not forget to block
the counter nut.
model 2 groups or more
The HP valve is located in the lower part at the left rear of the appliance: it is
necessary to dismantle the left side. The valve must open at about 13 bar [1.3
MPa] (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] TIGHTEN
Use the tool reference OU003; after the adjustment, do not forget to block
the counter nut.
G.4.3 Adjusting the pump pressure
During infusion, the pressure must be 9 to 10 bar [0.9 MPa et 1 MPa] (gauge
green 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 pressure
G.4.4 Adjusting the coffee grinding
Wait 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 which
determines the time for passing the hot water through the dose. This time is usually monitored by using the two-cup filter with two
doses 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 Softener
Test 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.
