12 DESCRIPTION OF THE APPLIANCE

This is a washing and disinfecting machine (thermal model) designed and built to empty, wash and disinfect bedpans, urinals,
commodes , urology containers, kidney-shaped basins, drainage bottles and other clinical containers used in hospital wards. The
machine, using washing jets inside the basin, can thoroughly wash the above-indicated products. It then introduces high temperature
steam to perform disinfecting (In the chemical model there is not a disinfection stage and the machine perform only a chemical wash).
All these procedures are performed according to suitable wash programs and following the instructions indicated in the" Machine
wash programs" paragraph (page 42).
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 DIN
1988-4 (12.88) 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 necessary water from this tank.
Disinfecting (thermal model only) can be done by introducing steam directly into the wash basin. This steam can be generated
either by a special boiler called a "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) for a time period of at least one
minute.
The items to wash and disinfect are inserted on special supports.
Suitable wash programs make the machine totally independent. The operator, when the wash cycle is being performed, is free to
perform other tasks until the entire wash and disinfecting cycle is terminated.

12.1 Disinfecting systems

The machine can be equipped with two different disinfecting systems (the chemical machine perform only a washing program,
WITHOUT disinfecting goods):

12.1.1 Thermal disinfecting with a steam generator (self-generated steam)

A small boiler, during each wash cycle, uses a heating coil to heat the water to generate steam. Special software is used to adjust
the disinfecting temperature and its duration.
All the 15883 machines start automatically, every 24 hours, a self disinfection system, compounded by some wash phases, a
disinfection phase and a final rinse with treated water (more than 65°C).
In this case it is necessary, during the not-working of the machine or, best, after every wash cycle, the closing of the door, both in the
cases of automatic and manual door.

10.1.2 Thermal disinfecting by connection to a steam pipeline network

Steam is taken directly from the local steam pipeline network. Flow is adjusted by a solenoid valve that permits or prevents steam
from entering into the basin to perform disinfecting.

12.2 Accessories

12.2.1 Automatic door opening and closing (Model AF2.60Ex)

Door opening and closing is commanded by an electric system actuated by a pedal-controlled switch (see page I appendix I, position
7). An infrared sensor, with the same functions as the pedal, can be activated as an option (see page I appendix I, position 10).
Touching the button for the desired wash program (see page I appendix I, position 11 and 2) 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
door closing, movement is blocked by something then it will partially reopen to prevent damage to persons and property. If
movement is blocked when the door is opening then the door stops in place. The red push-button (see page I appendix I, position 8)
permits instantaneous stoppage of any machine function (including door movement) in case of an emergency. To reset machine
operation just rotate the emergency push-button in the direction of the arrow until it is released.
Door opening at the end of the wash cycle can also be automatic (optional). This speeds up drying of the products being washed and
also informs the operator that the wash cycle is terminated: he can see that the appliance has terminated its work cycle and is ready
to start a new cycle.
The red emergency push-button functions to block machine functions, not to interrupt
electrical power. To interrupt electrical power turn off the service switch or the main switch.
