supply is correct, first check the reason why water
is not running in the boiler.
For further troubles or anomalies in operation,
please read the chapter "Breakdowns to the boiler
and to electronic level".
In operation when the correct water level is
obtained the heating elements are switched on.
As the water level decreases and the level sensor
probe becomes uncovered, the water pump and
inlet valve are again switched on without switching
off the heating elements that if after this 20
seconds delay the correct water level is not
restored than the heating elements are switched
off automatically.
If after 2 minutes, the water has not reached the
level to work, the timer will block the water loading
device safeguarding it.
SHUTTING DOWN OF THE
MACHINE
(SEE DRAWINGS PAGE 13-1 AND 10-11)
a) A few minutes before stopping work, turn off
the boiler by "POS. 57" and continue working
until the steam is finished.
b) When the boiler pressure has dropped below
approximately 1 bar (approximately 15 psi),
open the discharge gate valve "POS.17",
empty the boiler and then close the gate
valve. Turn the boiler on again, and run in
fresh water. As soon as the pump has
stopped, turn the boiler off without draining it.
c) Turn off the water supply ball valve "POS
d) In the case of machine with steam spotting
gun, close the ball tap assembled on the air
compression line "POS. 25".
e) Disconnect the switch "POS. 69", then the
main switch on the electrical current line.
N.B.: It is advisable to carry out the procedure in
1b every evening to ensure a long and efficient
boiler life and to avoid the siphoning-back of
water.
MAINTENANCE
The following instructions are of prime importance
in
keeping
the
machine
ensuring its maximum performance, and avoiding
expensive down time.
The first part of this section is divided into
chapters according to periodic maintenance
schedules.
N.B.: The frequency indicated (weekly, monthly,
etc.) is indicative and refers to a machine that
operates under 'normal' conditions.

exact frequency of the maintenance work on the
basis of the following guide lines:
the amount of work done by the machine;
the hardness of the water, which causes a
greater or lesser scaling of the boiler heating
element;
the amount of dust in the air;
other local working conditions.
All
the
maintenance
undertaken with the machine completely switched
off, and in particular:
a) The general electrical power switch must be
off and the plug removed from the socket;
b) The water supply ball "POS. 66" must be
closed. The boiler drainage valve "POS. 17"
must be closed;
c) In case of machine with spotting gun the
compressed air ball valve "POS. 25" must be
closed and all the compressed air in the
machine must be discharged.
d) The hot parts of the machine must be left to
cool (internal pipes, valves, boiler, etc.) in
order to avoid burns.
Only by observing all these precautions, and the
particular conditions relating to the individual
maintenance jobs, is it possible to carry out
maintenance work on the machine with complete
safety. Remember 'you can never be too
careful'!
In order to make potential dangers more evident,
adhesive symbols have been applied to critical
parts of the machine: the meaning of these
symbols is explained in detail in the red section at
the beginning of this manual (Prescription, danger
and indication signals).
N.B. In any case, the maintenance work must
be undertaken only by competent personnel
who can take personal responsibility for their
own safety and that of other persons, animals
and property. The law, and in particular the
latest EU Directives, severely punish the
owner of a machine who allows maintenance
work to be carried out by non-qualified
personnel.
WEEKLY MAINTENANCE
Proceed as follows:
a) Boiler safety valves: check carefully its
correct working and that it does not vent
steam. In the case of a malfunction, replace
the whole safety valve: request the services
of a competent technician.
b) Also check the correct functioning of the
gauge, pressure gauge and pump.
