● Place the machine on the horizontal surface pre-

viously prepared.

Before connecting, thoroughly wash the mains water

pipes:

● Leave the water supply taps running at full pres-

sure for several minutes.

● Connect to the mains water supply.

● Connect the machine to the socket.

Thoroughly wash all the water pipes of the machi-

ne:

● Leave the water supply taps running at full pres-

sure.

● Switch on main switch 1 (Fig.7): wait until the boiler

fills up to the level set.

● Switch on boiler resistance switch 2 (Fig.7) to begin

heating the water in the boiler.

● Operate each unit in order to allow the water to

escape for about one minute; repeat the operation

twice.

● Deliver steam from the steam jets for about one

minute.

● Deliver hot water for about one minute; repeat the

operation twice.

● Switch off switches 1 and 2.

● Empty the water from the boiler: see point

10.3.1.

IMPORTANT

Should the machine not deliver water for over

24 hours, wash the internal components be-

fore beginning work, repeating the operations

as described above.

6.1. Connections to be made by the

user

Hook-up must be carried out by qualified

personnel in full accordance with federal,

state and local regulations.

6.1.1. Water supply (Fig.5)

This equipment is to be installed to

comply with the applicable federal, state

or local plumbing codes.

Connections must be installed close to the machine.

● Water drainage pipe 1, having a minimum internal

diameter of 30 mm, equipped with a water-trap

accessible for inspection.

● Water supply pipe 2, with a 3/8"G cut-off tap.

Make sure that the maximum supply pressure

does not exceed 6.5 bar; otherwise, install a

pressure reducer.

6.1.2. Electric supply (Fig.5)

The machine is supplied ready for connection

according to the required electrical specifications.

Before connecting the machine ensure that the plate

details 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 3 conductors

( 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 automatic

differential switch 4 (Fig. 5) at the start of the power

cable, complete with magnetic release elements in

accordance with the identification plate details (Fig.

1). The contacts must have an opening of equal or

over 3 mm and with dispersed current protection of

30 mA.

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.

CONNECTION

This connection, which is the one called for by several

norms, avoids electrical potential differences, building

up between any equipment that may be installed in

the same room. There is a terminal clip on the under

side of the base of the machine to which an external

potential-equalizing wire should be connected.

This connection is ABSOLUTELY NECESSARY and

must be made right after the machine is installed.

Use a wire whose cross-sectional area conforms to

the existing norms.
