6.1.2. Electric supply

The machine is supplied ready for connection according to the required electrical specifications. Before connecting the machine ensure that the plate details (fig. 1) comply with those of the electric distribution network.

The electrical connection cable must be directly connected to the connection provided according to current legislation. Ensure that the earthing system is efficient and in compliance with current legal re- quirements.

The earthing system and the lightening protection system must be realized in accordance with the provisions of current legislation.

For the supply network use a cable in compliance with standards with protective conductor (earthing wire).

For three-phase power use a cable with 5 conduc- tors ( 3 phases + neutral + earth).

For single phase power supply use a cable with 3 conductors (phase + neutral + earth).

In both cases it is necessary to provide an auto- matic differential switch (Fig. 6) at the start of the power cable, complete with magnetic release ele- ments in accordance with the identification plate details (Fig. 1). The contact opening must be equivalent or over 3 mm.

Remember that each machine must be fitted with its own safety elements.

WARNING:

Should the power supply cable be damaged it is to be replaced by the manufacturer or by its technical assistance service or by person with equivalent qualification, in order to pre- vent any risks.

6.2. Preliminary operations

ANTISUCTION VALVE INSTALLATION

On the top of the boiler there is the antisuction valve.

When installing the machine make sure to remove the plastic fork “A” and check that the pin ”B” is not blocked.

This operation is very important for the correct working of the machine.

zConnect the gas pipe (model SYSTEM)

Thoroughly wash all the water pipes of the machine:

zLeave the water supply taps running at full pressure.

zSwitch on main switch 1: wait until the boiler fills up to the level set.

zSwitch on main switch 2 to begin heating the water in the boiler.

zOperate each unit in order to allow the water to escape for about one minute; repeat the operation twice.

zDeliver steam from the steam jets for about one minute.

zDeliver hot water for about one minute; repeat the operation twice.

zSwitch off switches 1 and 2.

zEmpty the water from the boiler: see point 10.3
