agent or similarly qualified persons in order to avoid a hazard. As in international provisions,
before setting up the appliance a unipolar device has to be installed with a contact opening of
at least 3 mm that must not interrupt the YELLOW-GREEN earthing wire. This device has to
be installed near the appliance, has to be approved, and has to have adequate capacity for the
absorption of the appliance (see table TECHNICAL FEATURES).
The appliance has to be connected to the EQUIPOTENTIAL system. The connector is situated near
the end of the electric cable and it is identified by a label with the symbol shown.
While using a safety thermostat for breakdown tensions, it is necessary to note what follows:
- According to the normative law in force, the leakage of electric power for this kind of appliances
can have a value of 1 mA without limitations for the maximum for each kW of installed power.
Besides, it must be noted that all the switches for breakdown to be found on the market have a
tolerance for the operating tension of less than the 50%; therefore, a suitable switch has to be
chosen.
- Connect only a single appliance to each switch.
- In some cases, after long periods of inactivity or in case of a new installation, it is possible that
the appliance switches off during the setting-up. The main reason is usually the moist produced
during the isolation. The problem can be easily solved through a short pre-heating bypassing the
safety thermostat.

Connection to the water mains
Connect the water inlet pipe to the mains, following the rules stipulated by the norms in force.
Drainage
The drainage pipe must not be connected directly to a common drain, but positioned over a reservoir,
at a distance which does not allow it come into contact with the sides of the reservoir or with the
water inside it, in order to avoid contaminating the food in the tank.
Checking gas tightness and pressure
Before checking the gas pressure, it is necessary to check the tightness of the gas installation up to
the nozzle with a leak-finder spray to ensure that no damage has been done to the appliance during
transportation. Then, it is possible to check the inlet pressure, which can be carried out by means of
a pressure gauge, either a "U" gauge or an electronic gauge with a minimum definition of 0,1 mbar.
In order to measure the gas pressure, remove the screw (1) from the pressure outlet (2) and connect
