INSTALLATION AND START UP
1. Connecting the machine to the domestic water supply must be performed by a qualied person.
Contact a service technician to do this task you are not condent 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. Ensure that a water ltration device or system is installed in-line in the domestic water supply
ahead the machine to prevent contamination inside the machine’s hydraulic system. Contact a
service technician to do this task if you are not confident about performing the steps below.
5. Open the water tap and allow the lter to ll (if new/previously unused). Then the machine’s
steam boiler will begin to ll. Check carefully around the service area for leaks or drips. If leaks/
drips are detected turn off the tap immediately and check/tighten any leaking ttings.
6. 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.
7. 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. If the machine is to be moved or relocated,
replace the hose set with a new parts from the distributor/
manufacture.

Pro Tip:
Always maintain the water ltration device or system in accordance with the manufacture’s
specications. Failure to routinely maintain the ltration device or system will result in limescale
build-up inside the machine’s hydraulic system which will eventually result in machine failure.
