INSTALLATION AND START UP
1. Connecting the machine to the domestic water supply must be performed by a qualied person.
Contact a service technician to do this task you are not condent about performing the steps
below.
2. Purge at least 20 liters of water from the domestic water supply before connecting the machine to it to
ush out any debris that may be in the plumbing system that would otherwise accumulate inside the boilers.
3. The domestic plumbing system should be tted with a brass 3/8” NPT male pipe tting and an in-
line shut-off valve. Connect the 180cm water inlet hose included with the machine to the domestic
water supply and tighten the line ttings with a wrench to 15 ft. lbs. / 20N-m.
4. Only use safe drinking water with a hardness rating between 5ºfH and 8ºfH (French hardness
degrees) or 20 to 32 ppm (parts per million of calcium). If the hardness value is below this limit,
corrosion of hydraulic components is likely. If the value is higher, lime-scaling inside the boiler will
occur. In both cases, the proper function of the machine and quality and taste of the coffee will be
negatively affected.
5. If necessary, connect the machine to a water softener to reduce water hardness using the exible
55cm hose included in the accessory box.
Important:
Only use the hoses supplied with the machine. Never reuse damaged hoses.
