General information
The machine must be operated with soft, clean drinking water. If the local water
supply has a high mineral content use a water softener. A build-up of mineral
deposit may restrict the flow of water within the hydraulic systems causing
damage to the machine and risking personal injury. Otherwise, very
“pure/sweet” water may interfere with the electronic signals read by the machine
for both boiler level and water reservoir level indications: use a filtered water.
Instructions for connection to the water supply:
1. The maximum inlet pressure is 0,4 MPa (4 bar).
If the supply pressure is higher, use a pressure reducer
2. The minimum inlet pressure is 0,8 MPa.
3. Always use the tubes supplied with the machine.
The machine is not to be used by persons with physical or mental disabilities or
without experience, unless they have been properly instructed beforehand.
Safety
The coffee boiler is fitted with a mechanical spring valve against over-pressure,
set at 10 bar and has a thermal switch that stops the heating in the event of
failure.
The steam boiler has a safety valve set at 2,3 Bar and a thermal switch that
stops the heating in the event of failure.
The pump is fitted with a thermal switch that resets automatically for protection
against overheating.
All the heating elements and those electrically powered are located inside the
machine panelling.
Vibrations
The machine is supplied with rubber vibration damping feet. In normal working
conditions the machine does not generate vibrations which could damage
objects or cause injury to persons.
