(gauge green scale).
The pump is located on the right side of the machine and is
adjusted by this same side.
SCREW IN to INCREASE the pressure,
UNSCREW to DECREASE the pressure,
♦Adjusting the water entry solenoid valve
The solenoid valve is located at the top, on the back-right of the
machine. It is necessary to remove the cup heater.
Machine at temperature, launch a cycle (with co󰀨ee) continuously
on each unit simultaneously.
Make the boiler ll up (draw hot water). Adjust the maximum
ow rate of the solenoid valve so as not to descend below 7 bar
(0.7MPa).
Then check that the lling time of the boiler is not excessive.
♦Adjusting the coee grinding
Wait until the machine has reached the set temperature 0.9 to 1 bar (0.09MPa à 0.1MPa).
It is the nesse 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 lter with two doses of co󰀨ee.
Average passing time for 2 cups (6 to 7 cl. per cup): 30 to 35 seconds.
- If this time is shorter, reduce the grinding.
- If this time is too long, increase the grinding.
To obtain a good result, use at least 6 g. of (good) ground co󰀨ee per cup.
♦Ambiance lighting
The switch for the ambient lighting is located to the left of the
machine near the basin. It lights up the grille strip, and if your
machine is so equipped, the lighting of the cups. 0=OFF & 1=ON.
♦Adjustment of mixer tap for the hot water
The mixer tap is located at the top, on the front-right of the machine.
For access, it is necessary to remove the right side.
The temperature range is 55°C to 95°C (131°F à 203°F). To adjust
the desired temperature, use a at screwdriver. We adjust the
cold circuit electrovalve , open at his maximum the high circuit
