Nuova Simonelli cannot be held liable for any

CAUTION
ELECTRIC SHOCK HAZARD
All models
are equipped with a level
gauge to keep the water level inside the boiler
constant.
When using the machine for the first time, it is advis-
able to fill the boiler by hand to avoid damaging
the electrical resistor and turning on the electronic
protection.
If this should happen, just turn the machine off

• remove the sheet metal guard by unscrewing the
four screws at the sides (A), as illustrated in the
following figure;
• use the manual level valve to allow water to enter
the boiler tank for about 20-30 secs.;
