where these parameters will not be exceeded:
- Maximum inlet water pressure: 0.9MPa (9 Bar), or 1.0MPa (10
Bar) [only for Norway, Sweden and Denmark]
- Minimum inlet water pressure:
0.0MPa (0 Bar)
Note: For a suitable performance of machine, maximum inlet water
pressure should be kept between 0.8-0.9MPa. Install a pressure
reducer in case water pressure exceeds this range.
- Maximum inlet water temperature: 40ºC
- Ambient temperature between +10ºC (min.) and +40ºC (max.).
Install the machine in a horizontal position and away from heat
sources and ammable objects.

GENERAL INFORMATION
· Warnings and Precautions
The appliance is not suitable for installation in an area where a
water jet could be used. This appliance must not be cleaned
with a water jet or a pressure washer.
The appliance is not suitable for outdoor use, where it would be
exposed to severe weather or extreme temperatures.
The instructions for appliances connected to the water mains by
detachable hose-sets shall state that the new hose-sets supplied
with the appliance are to be used and that old hose-sets should
not be reused.
Use the inlet hose included with the machine to connect it to the
water mains in accordance with the national rules applicable in the
country where machine is installed.
Plug the machine into a properly installed, earth grounded
electrical outlet with line voltage that matches the specications
for the machine.
For appliances not tted with a supply cord and a plug, means for
disconnection must be incorporated in the xed wiring in accordance
with the wiring rules.
Ensure that the power supply voltage does not uctuate by more than 6%.
Position the power cable so that users cannot trip over it. Keep the
power cable away from sharp edges and heat sources.
Do not remove or disable any of the mechanical, electrical, or thermal
protection safety equipment.
If supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualied persons in order to avoid a hazard.
In case of emergency, (e.g., the machine catches re or becomes
unusually hot or noisy), disconnect the power immediately and turn
o the water supply.
If the machine is not going to be used for an extended period of time,
disconnect the power. When disconnecting the power, pull the plug
rather than the cable.
Keep all hazardous packaging materials, such as plastic bags,
styrofoam, and staples, out of reach of children.

INSTALLATION AND START UP
· Machine positioning
MIN. 10 cm
MIN. 30 cm
Install within 0-3º horizontal.
1. Installing the machine in the service area must be performed by a qualied person. As the
machine may be quite heavy, at least two strong, capable individuals are recommend to
work together to lift and position the machine. Consult the Technical Specications page
for the specic machine model being installed for machine weight and dimensions details.
Contact a service technician to do this task if you are not condent about performing the
steps below.
2. Position the machine on a level, sturdy, and water-resistant surface approximately 110cm
above oor level for ease of access and usage.
3. Adjust the feet to ensure that it dispenses coee evenly to all cups.
4. Ensure enough free space is available above (>30cm) and behind (>10cm) the machine to
ensure easy cleaning and maintenance and adequate ventilation.
Important:
Leave an air gap of at least 30cm above the machine and 10cm behind it to ensure adequate
ventilation. The machine must be installed within 3º of horizontally level front-to-back and
side-to-side to ensure proper hydraulic function and drainage. Conrm with a spirit level or
digital angle gauge.
Do not install the machine if the machine or installation surface it is wet. Allow it to dry
completely and ask a service technician to ensure that none of the electrical components
have been aected.
