It is good practice to install the water supply tap
outside the machine in an easily accessible position.
OVERFLOW DEVICE
The water inlet solenoid valve (see Fig. 16) is equipped
with an overflow device which mechanically stops the
water inlet if there is a malfunction in the solenoid valve or
in the boiler water level control device.
To restore normal operation, proceed as follows:
- disconnect the electricity from the machine;
- drain the water contained in the overflow hose;
- shut off the water supply using the tap outside the
machine;
- loosen the nut which secures the solenoid valve supply
hose to relieve the water mains residual pressure and
then tighten again (see Fig. 16);
- open the tap and switch the machine on.
CONNECTING THE MACHINE TO THE
POWER SUPPLY
The machine is designed to operate under single-phase
230 V~ voltage and is protected by 15 A fuses.
Before making the connection, ensure that the rating
corresponds to that of the power grid, and more specifi-
cally:
- the supply voltage rating must be within the range
recommended for the connection points;
- the main switch should be capable of withstanding the
peak load required, and at the same time ensure proper
omnipolar disconnection from the power grid with an
opening gap of the contacts of at least 3 mm.
The switch, the power outlet and the plug must be
located in an easily accessible position.
The electrical safety of the machine is ensured only when
it is correctly earthed according to the safety standards in
force.
This fundamental safety requirement must be duly
verified, and if in doubt the system must be carefully
tested by qualified technicians.
The power supply cable is of the type with a fixed plug.
Replacement of the power cable (see Fig. 17) should be
carried out by qualified and suitably trained personnel only
using cables type HO5 RN-F or HO5 V V-F or H07 RN-F
with a 3x1-1.5 mm
2
section.
Do not use adapters, multiple sockets and/or exten-
sions.
THE MANUFACTURER DECLINES ALL RESPONSI-
BILITY FOR ANY DAMAGE CAUSED BY NONCOMPLI-
ANCE WITH THE ABOVE MENTIONED PRECAUTIONS.
DOOR SWITCH
When opening the door a special micro-switch discon-
nects the power from the machine electrical system.
To energize the system with the open door, simply insert
the special key into the slot (see Fig. 14).
With the door open there is no access to energised
parts. Inside the machine, the only parts that stay
energised are those protected by covers and carrying
a plate with the warning “disconnect the power before
removing the protective cover”.
Before removing such covers disconnect the power
supply cable.
The door can be closed only after removing the yellow key
from door switch and lowering the machine top panel.
