following issues may require clarification: The operation of the autoclave; the door safety
mechanism; the door closing mechanism; the dangers involved in circumventing safety
means; and finally, the selection of an appropriate sterilization program.
Make sure that you know the placement of the main power switch, the position of the
water cut-off valve, where the steam and compressed air disconnection valves are
located.
Autoclave maintenance is crucial for the correct and efficient function of the device.
The daily B&D test and the weekly spore test are part of the preventive maintenance
plan, along with the annual validation of the sterilization processes that ensures
appropriate temperature dispersion within the chamber.
Warning!
Never use the autoclave for the sterilization of corrosive products and chemicals ,
such as: Acids, bases and phenols, volatile compounds or solutions such
ethanol, methanol or chloroform nor radioactive substances.
Safety Operation Instructions
1. NEVER start a new autoclave or a new steam generator, before the safety,
licensing, and authorization department has not approved it for use.
2. All autoclave users must receive training in proper usage from an experienced
employee. Every new employee must undergo a training period under an
experienced employee.
3. A written procedure must be established for autoclave operation, including:
Daily safety tests; seal inspection and door hinge inspection; smooth action of

1. GENERAL INFORMATION
1.1 Introduction
This autoclave is designed to cover a large field of applications for hospitals and medical
centers as well as pharmaceutical and biotechnological industries.
The autoclave operates with saturated steam as the sterilizing agent, and has a
temperature range of up to 137C (279ºF) and pressure up to 2.3 bar (34 psi).
The autoclave is equipped with a 36 kW built-in steam generator. This steam generator
acts as a standby if building steam is not available for the sterilization process.
The autoclave is built to receive two steam supply sources, namely from the building, or
from an internal built in steam generator. There is a selector switch on the Front Panel to
choose the source. Before selecting the external generator, check the generator is
connected to the electrical supply and working properly.
The autoclave is equipped with two vertical sliding doors. Each door is operated by two
hydro-pneumatic cylinders mounted laterally on both sides of the door. Each cylinder
contains an integrated and separated oil system. The operation of the cylinders is
performed by air pressure and the oil system acts as a speed control system. An
adjustable restrictor controls the flow of oil from one side to the other side on each
cylinder, controlling the speed movement of the door. (For servicing of the unit see the
SERVICING INSTRUCTIONS chapter.)
The autoclave is mounted through a recessed wall. The two doors are located in two
separate rooms.
The front door, on the side of the master control panel is in the preparation area, from
where the autoclave is operated and serves for loading the material into the sterilization
chamber. This area is known as the "dirty side." The rear door is located on the "clean
side" and serves for unloading the sterilized material from the autoclave. This side of
autoclave is equipped with secondary control panel (slave).
The sealing of the chamber is achieved through a heat resistant silicone gasket, located
in a groove around the door opening of the autoclave. The gasket is pressed against the
door by steam pressure introduced into the groove behind the gasket.
The interlocking system of the door is based on the following opening conditions:
A door cannot be opened while the autoclave is in operation.
A door cannot be opened if the chamber is under pressure.
A door cannot be opened if there is liquid in the chamber.
Both doors cannot be opened at the same time. Opening of one door
automatically locks the other.

MAN205-0195042EN Rev. A Aug. 2011
Page 5 of 137 pages
After opening the door on the dirty side, even after closing it and it being
locked and sealed, the door on the clean side can be opened only after
performing a complete sterilization cycle.
If cycle failed, the front door only can be opened.
After test cycle, the front door only can be opened.
A door cannot be opened at the end of the cycle if the chamber temperature is
higher than the preset final temperature.
The electronic circuitry and software programming of the programmable control system
are designed to operate 10 sterilization programs. Three programs are intended for un-
wrapped instruments, four for wrapped instruments and packs, three for slow exhaust
pressure cycles. In addition, there are two test programs: Bowie & Dick Test and the
Leakage Test.
The control system of the sterilizer is based on microcomputer technology, ensuring a
highly reliable and safe operation. The computerized control unit ensures a fully
automatic operation through the entire cycle; hence, after setting the pre-selected
parameters and starting the operation, no further operator intervention is necessary.
The autoclave has an automatic shutdown system. If no buttons or switches are
operated for four hours, it will go into SLEEP MODE and a LED lights up (blinking every
second), indicating that the system is in the SLEEP MODE.
The selected program, the main phases of the cycle and the status of the machine are
controlled and displayed on digital readouts. For process documentation, the important
information concerning operation is printed.
The system is equipped with two temperature sensors,four pressure transducers, five
pressure gauges, and safety devices having the following functions:
The temperature sensors:
1. In the drain –(control)
2. In the condensate line(double) –(control, monitoring, and printout)
The pressure transducers measure:
1. Chamber pressure –(control, display, and printout)
2. Jacket pressure –(control and monitoring)
3. Door 1 gasket pressure –(control and monitoring)
4. Door 2 gasket pressure –(control and monitoring)

MAN205-0195042EN Rev. A Aug. 2011

The pressure gauges:
Front Panel
Service Area
1. Chamber pressure
2. Jacket pressure
3. Door 1 gasket pressure
4. Door 2 gasket pressure
5. Steam generator pressure
The safety devices:
1. RT112 pressure switch –(prevents the opening of the door if there is
pressure in the chamber)
2. Two ALCO pressure switches –(prevents the operating of the door if
there is no vacuum in the door gasket)
3. RANCO over pressure switch –(control the over pressure of the steam
generator)
4. SMS VM830 end switch –(prevents the pressurizing of the chamber
and the door gasket if the door is not closed)
5. Two Safety Bars –(prevent the door from trapping any object while
closing)
6. A GICAR controller connected to a water level electrode in the chamber
prevents opening of the door if there is liquid in the chamber.
The keyboards located on both the front and rear panels enables the operator to select a
sterilization program, start/stop a cycle, and close or open a door.
A programming mode, which can be accessed by a code from the front panel only,
enables the technician to set up the system, set and change a number of additional
parameters and operational modes and performing a calibration.
Optionally, a personal computer can be connected to the control system, through the
interface board RS232, which can be operated up to 8 meters away from the autoclave.
The PC, operating under WINDOWS displays the status, data and processing in real
time in graphic and digital form at the same time recording and logging the data. For a
distance more than 8 meters, a RS485 interface and a modem are required.
The communication PC-control unit enables the complete control of the autoclave
through the PC, including program selection, starting and stopping a cycle, setting of
parameters, and the real time clock (date and time of the day).
The autoclave is equipped with ―Emergency Stop‖ push-buttons and key locks, mounted
on both the front and rear panel. This feature is designed to prevent human hazards,
accidents or equipment breakdown in compliance with the European standards EN-285
requirements.
