N.B.:
If
local
regulations
contamination of the water mains so require,
install a water feed tank or one-way flow device to
prevent the back-flow of possibly polluted water to
the water mains (for example, a GIACOMINI R
624).
N.B.: It is advisable to avoid connecting a water
softener as the use of treated water in small
electrical boilers causes the formation of copious
quantities of foam which is drawn in to the
machine when steam is used, with consequent
damage to the clothes.
In the case of excessively hard water (more than
17° French=12° English), a water softener may be
installed to reduce the dissolved salts by no more
than 10° (French) or 7° (English).
COMPRESSED AIR
CONNECTION
(ONLY FOR MACHINE WITH SPOTTING GUN)
The machine needs to be fed with clean
compressed air, without condensation or oil, at a
pressure of 7 bars (100 psi).
Fit a rilsan or zinc-platted 1/4" gas pipe to within 1
meter of the machine. Assemble a three-way ball
tap or a sliding tap on its end "POS. 25".
This 3-way ball valve serves to feed the machine
(position 1 = ON = OK) or to turn off the supply
(position 0 = STOP) by discharging the air
remaining in the machine through the silencer.
This ensures that whenever any maintenance is
required, there is the guarantee that there is no
danger from compressed air (jets of air, etc.)
simply by turning the air ball valve to the 0 =
STOP position (or letting the ring nut slip).
Using a pipe in rilsan, inside=6mm (0,23
inches) resistant up to a pressure of at least 20
bars (290 psi), connect the tap to the air solenoid
valve of the spotting gun "POS. 47".
ELECTRICAL CONNECTION
(SEE DRAWING PAGE 10-10)
Ensure that the mains voltage and phase
correspond with the data given on the machine
specification plate (see page 2-1).
Prepare
an
electrical
indicated on the table shown in the drawing.
Insert the cable in the holder "POS. 8" and block
it. Connect with the clamps to the electrical
current.

The electrical supply line must be fitted with an
automatic differential heat safety cut-out switch 30
mA with a mechanical plug and socket block.
The machine as per the rules in force must be
connected to a good earth, or the guarantee will
not be honoured.
Before first testing the machine, check that none
of the electrical connectors have worked loose
during transport.
After connection to the electricity supply, check
the rotation direction of the motors (fan).
If the direction is wrong, invert the connection of
two of the three phases supply wires.
Replace all the panels and protection devices
when the electrical connections have been
completed.
BOILER WASHING
(SEE DRAWING PAGE 10-11)
When a new machine is installed, or when
restarting after it has been stopped for more than
one week, the boiler must be thoroughly
washed.
The procedure is as follows:
a) Turn on the boiler and bring it to a pressure of
approximately 2 bars (30 psi).
b) Turn the boiler off and drain the water into the
main drains or drainage tank half opening the
tap "POS. 17", taking care not to burn
yourself.
c) When all the water has been drained, turn off
the drainage valve "POS. 17". The water will
probably be a dark colour.
d) Turn the boiler on again and bring it to a
pressure of 2 bars (30 psi).
e) Repeat the cycle of points b) - c) - d) four
times.
The water should progressively become
cleaner. If it is still dirty, repeat the washing
cycle another 3 or 4 times, until it is
completely clean.
If the boiler is not washed as described above
there is the risk of dirty water being siphoned
back, or a rust colour visible during steaming.
USE OF THE MACHINE
PRELIMINARY CONTROLS
Proceed as follows (see drawing page 10-11):
a) Check that the drainage ball valve "POS. 17"
is well closed
b) Check that the water feed ball "POS. 66" is
open
c) In case of machine with steam-air spotting
gun, check that the ball tap for the
compressed air feed "POS. 25" is open.
d) If the machine has been stopped for a long
time check that the pump is not jammed due
to internal deposit. Check that the shaft turns
