drainage bottles and other human waste containers.
The device, using washing jets inside the washing
chamber, can thoroughly empty and wash the above
indicated products. After washing, a disinfection is
performed introducing high temperature steam. All
these procedures are performed according to suitable
wash programs and following the instructions indicated
in the “Machine wash programs” paragraph.
Electricity is used to power the appliance and can also
be used to generate steam when the machine has a
built-in steam generator.
Containers are emptied automatically when the door is
closed. The material in the containers is dumped into
the wash chamber and passes through the drain trap to
go to the sewer system.
Washing is done using water coming directly from
the hot and cold water mains, with an anti-backflow
system according to EN 1717 Standards. Be advised
that wash programs are not influenced by variations in
water mains pressure as the machine has its own water
storage tank and a wash pump that takes the needed
water from this tank.
Disinfection is done introducing steam directly into the
wash basin. This steam can be generated either by a
special boiler called “steam generator" (if the machine
is equipped with this system), or can be taken directly
from a local steam pipeline network (if the building
has a steam pipeline network). In order for containers
introduced into the wash basin to be disinfected, the
temperature in the chamber must be kept above a
preset value (minimum 85°C/185°F) for a time period
of at least one minute.
The items to wash and disinfect are inserted on special
supports.
Every wash program of the device is totally automatic.
Once the wash cycle is started, the operator is free to
perform other tasks until the cycle is finished.
The validation process must be performed by the final
user, using the dirt, stated in the current regulations.
6.1 Configurations
6.1.1 Disinfecting systems
The machine can be equipped with two different
disinfecting systems:
Thermal disinfection with steam generator
During each wash cycle, a small boiler heat water to
generate steam using a heating coil. The device software
takes care of setting the disinfection temperature and
its duration.
All 15883 machines, when not used for 24 hours,
automatically start a disinfection cycle, composed by
some wash phases, a disinfection phase and a final
rinse with sanitized water (hotter than 65°C/149°F).
The door should always be closed when not working for
long periods of time, or, even better, after every wash
cycle, both for automatic and manual door.
Thermal disinfection with steam pipeline network
connection
Steam is taken directly from the local steam pipeline
network. Flow is regulated by a solenoid valve that
allows or prevents steam entrance into the basin to
perform the disinfection.
6.1.2 Safety thermostat
The machine model with steam generator, (meaning
with self-generated steam) is equipped with a safety
thermostat that interrupts power to the steam
generator heating coils when the temperature of the
heating coils exceeds a certain limit. Exceeding this
limit could cause damage to the heating elements. To
restart the appliance you must eliminate the causes
(the display will show the error message: "E40:
Overheating").
6.1.3 Automatic door
Door opening and closing is commanded by an electric
system actuated by a pedal-controlled switch and/
or by an infrared sensor. Touching the button for the
desired wash program causes the door to close and
after a few seconds, the wash cycle to start. A safety
device prevents the door from reopening before the
wash cycle is terminated. If during closing, the door
encounters any obstacle on its way, then it will partially
reopen to prevent damage to the person or object
on its way. If movement is blocked when the door is
opening then the door stops. The red push-button
instantaneously stops any machine function (including
door movement) in case of an emergency. To reset
machine operation just release the emergency push-
button, rotating it in the direction of the arrow.
Door opening at the end of the wash cycle is also be
automatic. This speeds up drying of the products being
washed and also informs the operator that the wash
cycle is terminated: the operator can see that the
appliance has terminated its work cycle and is ready to
start a new cycle.

WARNING! The red emergency push-
button blocks machine functions, it DOES
NOT interrupt electrical power. To interrupt
electrical power turn off the service switch or
the main switch.
