This sterilizer is designed in such a way as to prevent any contamination hazard to the environment and the operators. For this reason, the sterilizer operates as follows:
1. It does not extract the air from the chamber, since all filters, even high--retention ones, are useless in the presence of small agents, such as prions.
2. It keeps in the chamber the condensate that forms during the process, until the sterilization has been completed; however, the first condensate which may be produced is not sterile.
The steam + air mixture forming in the sterilization chamber is kept homogeneous by a fan positioned inside the chamber. As a matter of fact, the air density (at the same temperature and pressure) is approximately 1.7 times higher than the water steam density, and without this measure the air would stratify on the bottom of the chamber, resulting in intolerable temperature gradients. The temperature of the steam + water mixture forming in the chamber will depend on the selected sterilization temperature. The mixture pressure will consist of the addition of two factors:
1. The water steam pressure at the selected sterilization temperature.
2. The air pressure at the selected sterilization temperature.
If, for example, the sterilization process is carried out at 140_C:
-- factor 1 is 3,61 absolute bar (water steam pressure 140_C);
-- factor 2 can be calculated as follows: when the sterilizer is closed at room temperature (approx. 20_C), the pressure of the air closed in the chamber is about the room pressure, i.e. 1,0 absolute bar. The air, however, heats up at 140_C, increasing its pressure in the ratio of initial to final heating temperatures, and accordingly pressure becomes:
1,0 x
140 + 273
20 + 273
=1,0x
413
= 1,41 absolute bar
293
-- The total pressure of the steam + air mixture in the chamber will be 138_C: 3,61 + 1,41 = 5,02 absolute bar.
The sterilizer is therefore designed to operate up to 4.70 rel. or manometric bar (i.e. above the atmospheric pressure), up to 5.70 absolute bar.

2.3. RISKS DERIVING FROM USING THE SOFTWARE

The use of the software supplied by Fedegari together with its products is licensed to the customer, who will be fully
responsible for it (see also the General T erms of Sale).
CAUTION!
Fedegari or its representatives cannot be held liable for direct/indirect damage deriving from using the software, from its failures or the above mentioned license.

2.4. SAFETY WARNINGS

2.4.1. General warnings

CAUTION!
Most labor accidents are due to non--compliance with safety rules. All operators using the sterilizer must know and comply with the rules mentioned in this manual and on warning plates. Always observe the rules recommended below.
CAUTION!
Some electrical circuits of the machine remain supplied also when the master switch is off (in the ”0” position). These circuits are located inside the electrical board an d are adequately indicated.
CAUTION!
Do not inhibit the machine safety devices. When safety is not assured, all operations are allowed only to FEDEGARI’s personnel, or, with the manufacturer’s authorization, to the user’s trained staff.
CAUTION!
Before using the sterilizer, ALWAYS check that the materials to be processed are compatible with the cycles and steps of the sterilization program to be started. Make sure that the mate rials are free of molecular instability risks which, during product handling or processing, are likely to cause explosions.
CAUTION!
Do not perform any kind of jobs and changes on the machine and its fittings. Do not modify the sterilizer parts in order to fit other devices. In case of malfunctioning/accidents due to non--compliance with the above mentioned instructions,
#68181 Rev.1

Page 14
FEDEGARI shall not be liable for the related consequences. Do not hesitate to contact FEDEGARI whenever changes to the machine are required.
CAUTION!
CAREFULLY position the heat probe used also as a safety device for chamber opening temperature, according to the following instructions. Pay attention to the temperature displayed as:
* when the heat probe is placed between -- not inside -- the bottles of one of the lowest batch layers,
the heat probe can detect the sterilization chamber temperature. Therefore, always TAKE INTO ACCOUNT that the time required by bottle liquid to reach the temperature displayed by the heat probe is directly proportional to the bottle volume. For 50 cc bottles, the safety margin is 30° C (for larger bottles, this margin is to be increased) and the chamber must be cooled at a temperature not below 40°C, so that the bottle internal temperature is 70°C, which is an acceptable value.
* When placing the heat probe inside a bottle, plunged in its liquid, safety limits are not needed,
although the sample bottle could be broken during its processing. In this case, the heat probe will indicate the chamber temperature instead of the bottle temperature. Therefore, before opening the sterilizer, the operator MUST check that the heat probe placed inside the chamber is indicating the temperature based on the safety margin mentioned in the previous section (about 40°C).
CAUTION!
When extracted from the machine, bottles having an internal temperature of more than 70°C could explode, thus jeopardizing the operators. The maximum safety te mperature allowing to open the cover must be set at <70°C and parameter ”CHECK FINAL T” must be enabled by setting value ”1”.
CAUTION!
Thermal sterilization in the presence of low--boiling liquids (i.e. with steam tension higher than the water tension at the same temperature) and/or liquids flammable in the air (i.e. characterized by a ceiling of concentration in the air above which a fire may propagate) involves two kinds of hazard.
* At the temperatures typical of thermal sterilization (i.e. at least 105°C) a low--boiling liquid can
develop such a high pressure that the safety valve opens, letting any gas and/or steam out of the sterilizer, or preventing the correct performance of the sterilization process. For example, the presence of alcohol in a closed room causes a partial pressure, in the aeriform phase, of approx.
4.5 absolute bar at the traditional temperature of 121°C. This pressure depends only on temperature and is not affected by the quantity of alcohol. When the regulation of a s aturated steam ste rilization occurs ”in temperature”, at 121°C, the pressure tends to reach approx. 6.5 absolute bar, and the safety valve opens well before reaching this value. When the sterilization is regulated ”in pressure”, the pressure developed by the low--boiling liquid simulates the
May 2001

#68181 Rev.1
Page 15
reaching of the regulation pressure, preventing the supply of steam to the chamber; the temperature reached at the regulation pressure (3.50 absolute bar in case of decontamination cycles with Fedegari FOB and FVA sterilizers) is not 121°C, being just above 100°C. The process may indefinitely stop in the heating phase. Therefore, the presence of any low--boiling liquid may result in the hazardous release of contaminated material from the chamber or in the impossibility to carry out the sterilization.
* The eventual flammability of the liquid involves, of course, a fire hazard. The concentration of
flammable vapors in the air, as necessary for ignition, decreases based on temperature, while the true concentration increases according to it. In most cases, a fire may break out due to the level (even negligible) of static electricity entering with the vapor or, most frequently, with the cooling air. Also in those cases that, at present, are well--known, the damage has been limited to the interior of the sterilizer (that, of course, is shut--down), though it cannot be denied that the possible opening of the safety valve may propagate fire also outside it. A similar hazard is present when vacuum is applied at the end of the sterilization process. The flammable mixture is sucked by a machine not meant for it and any cause of firing may have serious consequences, that cannot be calculated.
CAUTION!
Before starting a sterilization cycle, make sure that the manual pressure relief valve is perfectly closed.
CAUTION!
C02 fire--fighting means are recommended in order to provide preventive protection.
WARNING
Always assure that:
* the supply voltage to the sterilizer is constantly kept within ±10% of the nominal value required.
* The compressed air pressure to the sterilizer pneumatic circuits is stable, within ±10% of the
nominal value required.
* the saturated steam pressure oscillation for the sterilization chamber is kept within ±10% of the
nominal values required.
* the pressure of water feed line to the sterilizer is kept within ±10% of the nominal values required.
Failure to comply with these recommendations may cause malfunctions during the sterilization cycles and damage the machine.
WARNING
Do not use alcohol, petrol, other solvents or acid reaction substances for cleaning or washing the chamber or the sterilizer components, as they are likely to attack stainless steel surfaces and

elastomer parts. Use water, also slightly diluted with neutral detergents, according to this manual’s maintenance instructions.
CAUTION
To avoid cuts during maintenance of the air circulation fan in the sterilization chamber, do not disassemble the fan and motor protections unless the plant is completely isolated from power supply sources.
WARNING

2.4.3.2. Personal protection means
Based on the batch to be processed, the operator must protect his body against the direct or indirect influence of
chemicals (whether organic or not) or microbiological elements (e.g. viruses, bacteria), forming the batch to be
sterilized or aggregated to it.
These substances can be noxious by contact, inhalation or contamination.
Always wear suitable protection means, such as masks, suits, gaberdines, gloves, protective glasses, footwear, boots
etc...
CAUTION!
The operator MUST be allowed to check the batch before its delivery, to verify the type of material included.
CAUTION!
The operator must wear suitable work clothing, to be protected against chemical, physical and/or microbiological risks, deriving from contact with a wide range of materials, including gases and liquids. The work clothing material and structure must be fit for protecting the operator against any contact/contamination dangers. The buyer is responsible for the use of highly protective means suitable for the type of product to be processed, in compliance with the rules in force in the country where the machine is used.
WARNING
All personal protection means must permit the operator t o move freely in order to carry out the necessary operations and to properly see with the best angulation and limited sight distortion. Use only certified protection means. All protection means must be carefully used and kept (e.g. wear them correctly, tighten the related closing systems, replace mask filters etc.).
WARNING
Personal protection means are sometimes recommended in order to protect the processed product against contamination (e.g., during unloading operations).
To treat products free of chemical or microbiological risks:
-- Wear a waterproof cotton one--piece suit or other work clothing, allowing for good transpiration and covering the
whole body, except for your face;
-- Wear suitable, comfortable shoes, for proper mechanical protection from spilled liquids;
-- Wear light, protective glasses against sprays. They should not be made of glass, without fragmentation danger,
transparent with the best refractive index, visual angulation and low distortion.

2.4.4. Recommendations and precautionary measures to be adopted by the user

The user must fit the installation area with suitable lighting devices, complying with safety and accident prevention
rules.
The user must assure that the area before the sterilizer is provided with an antislip flooring, in aggregate or polymeric
materials, easy to wash and fit for chemical and thermal disinfection.
The floor must be fit for any processing, according to the products to be sterilized.
Clear and legible warnings must be installed near the work station, to prevent unauthorized personnel from entering
the work area.
Before delivery, the user must train its operators and make sure that they are acquainted with the machine and able to
carry out the necessary operations, according to the skill profile mentioned in section
2.4.3.1.

2.4.5. Emergencies

The user must fit the area with proper fire--fighting stations.
CAUTION!
C02 fire--fighting means are recommended in order to provide preventive protection.
In an emergency, the operator must be free to reach the main switch and the primary feed shut--off valves.
Electric system black--out
In case of black--out, the main switch is activated to isolate all downstream elements.
All processes started before the black--out will be stopped.
When the electric power is restored, after resetting the main switch, the sterilizer enters an emergency state, waiting to
receive a manual control which brings the sterilization process to the cycle end phase or to the
Emergency--Decontamination phase, after an electrical blackout has occurred, during the ”Heating” or ”Sterilization”
phases, in the Decontamination Program.
The sterilization chamber features a pneumatic cover seal and the related devices, which assures chamber tightness
also in case of pneumatic or power failure.
Depressurizing the door pneumatic seal takes more than depressurizing the chamber.
The atmospheric pressure inside the chamber, caused by sealing failure due to a black--out, is reached after at least
20 hours, based on the machine maintenance level.
Pneumatic, steam and water supply failure
All supply line failures are detected by proper sensors and could considerably increase the time required to complete
the steps of the process in progress.
The sterilizer enters an emergency state, waiting for the reset of suitable parameters.

Steam generator (K10)
The steam generator is installed when no saturated steam is available to feed the sterilizer, or when the quality of the available steam is poor. The steam generator consists of pressurized reservoir D001, in AISI 316 stainless steel, supplied with deionized water evaporating by means of three electric heating elements RX02 fitted on the top of the reservoir. The loading of deionized water, supplied by the feed network and by a proper container through an electric pump PA 0 1 , is controlled by solenoid valve E009, which opens pneumatic valve S009. Check valve R004 prevents water from flowing to the pump. Pressure switch P004 detects pressure inside the generator, checks the heating element power supply and warns the process controller when the pressure reached allows to supply the chamber. Sensors L001 and L002 detect the water level inside the pressurized body. The steam generator is also fitted with the following devices, for the pressurized reservoir operational safety:
-- Manual discharge valve V004;
-- Safety valve Y002;
-- Pressure gauge M003 detecting reservoir D001 pressure, clearly visible to the operator;
-- The rmo sta t T002, controlling the heating element temperature and signaling dry operation;
-- The rmo sta t T003, if required, checking the generator maximum temperature (TÜV).
Vacuum pump unit (K20)
It consists of a liquid ring pump PV01, fed by the network water. Water enters the pump through solenoid valve E011 and is regulated by valve V003.ValveV007 adjusts the air ballast necessary to the vacuum pump through the air intake. Solenoid valve E011 opens when the motor is energized. The pump is used to create continuous as well as discontinuous (impulse) vacuum in the sterilizer chamber. This pump is required whenever air cushions in the batch could prevent its sterilization, as well as for product drying.
Effluent cooler (K30)
Effluent cooler W001 consists of a small mixing reservoir, fed by network water.The drain line condensate and gases are sent to the reservoir before being discharged outside the machine. The cooling system is regulated by thermostat
May 2001
-- 19 --
#68181 Rev.1
Page 29
T004 and solenoid valve E001, located on the network water feeding line. The cooler is used in order to lower the effluent temperature (up to 60_C) before letting it outside the sterilizer. The cooling unit must be fitted whenever low temperature effluent is required, e.g. when the regulations of the installation site do not allow for high--temperature effluent, or when the drain lines connected to the sterilizer are in plastic material, which is likely to be damaged by high temperature.
Internal air electrocompressor (K40)
It can be fitted into the machine cabinet, to be used when no network compressed air is available. The electrocompressor model and the related plenum chamber must be chosen based on the machine configuration. If the sterilizer is not used to process liquids, compressed air is only needed to feed the cover seal and the pneumatic valves. A 2 liters plenum chamber is sufficient to guarantee proper operation.
External Air electrocompressor (K43)
When the machine is used to carry out sterilization processes requiring compressed air, an external compressor must be installed featuring a plenum chamber with more than 10 liters capacity.
Sterilizing filter for air (K50)
The air filtering unit consists of a filter F007 which can be sterilized in the sterilizer, with 0,22 mm retention, fitted in a plastic container.
Network compressed air supply unit (K51)
This unit consists of solenoid valve E010 and pressure reducer VR02, which supplies the chamber with sterile compressed air. This unit must be installed on the sterilizer when the batch to be sterilized requires an air counter--pressure on completion of the sterilization process.
Quick cooling unit (K52)
The quick cooling unit basically consists of a magnetic fan CV12 and a heat exchanger located in the cover concavity. They are installed so that the sterilization chamber volume is not reduced. The fan coupled to the motor ME12 through a suitable magnetic joint must assure air circulation inside the chamber. Air is cooled when coming into contact with the surface of the heat exchanger, supplied by network water. This procedure allows to reduce the liquid cooling time and to increase the sterilizer performance. The quick cooling unit is recommended whenever the sterilizer is used to process heat--sensitive liquids, in particular when they are stored in large bottles.
Spontaneous cooling (K53)
This option allows the ”Slow spontaneous cooling” of the load. It requires the use of load interception electro--valve E007, that during the ”Spontaneous cooling” phase remains closed until the pressure inside the chamber is lower than/equal to the average of maximum and minimum balancing pressures. The opening of the valve allows the discharge of the condensate produced during the cooling phase. The phase ends
-- 20 --
#68181 Rev.1
May 2001
Page 30
as soon as the target Temperature is reached. During the ”Spontaneous cooling” phase, the pressure inside the chamber reaches balancing pressure values spontaneously, without creating a pressure drop that is likely to damage the batch, if consisting of liquids contained in reservoirs.
NOTE
The presence of option K51 ”Newtork compressed air supply unit” or option K52 ”Quick cooling unit” (including K51), disables the effect of option K53 ”Spontaneous cooling”, that in these cases is not enabled.
Pressurized chamber leak test (K61)
This option is used to perform the pressurized chamber leak test. It consists in shutting--off the discharge, usually connected to the chamber through a calibrated orifice. This test can be performed as an alternative to vacuum leak test in sterilizers lacking the necessary equipment. To carry out the pressure leak test, the machine must be fitted with the air supply unit in counterpressure (K51).
Decontamination cycle (K62)
This cycle is installed on the machine in order to sterilize products involving microbiological pollution risks. During the sterilization phase, start solenoid valve E071 to let saturated steam in, either through the chamber purge system or directly through S008. The chamber and the purge system must have the same temperature. Solenoid valve E007 is closed until completion of the sterilization process. Therefore, the sterilization chamber batch must not be removed until the process is completed, i.e. when the chamber content has been sterilized. The maximum allowed temperature is 121°C, equal to a 3.4 bar pressure with air/steam mixture.
Steam supply deflection unit (K70)
This device allows to selectively feed a sterilizer featuring an autonomous steam generator (K10), also with network steam. The operator enters a process controller parameter for manually deviating a three--way valve V009 inside the sterilizer technical cabinet.
Additional heat probe (K80)
This Pt 100 heat probe T005 is identical to that fitted on the sterilizer chamber. It can be connected to the process controller, which will provide for the second temperature measurement, to be printed with the first one, or to an optional external recorder.
Process printer (K81)
It is an alphanumeric printer installed next to the operator interface, in order to print detailed process documents. The printer is provided with a 200 dpi thermal printing mechanism, uses 57.7mm wide paper and is connected to the controller through a RS232 serial output.
Secondary R S232 serial output (HW1)
This option consists of a special software version loaded on the process controller, which enables the second PLC RS232 serial output. It can be used to download in real time all data of the process in progress to a remote PC, in ASCII format, or to connect a remote PC featuring the Fedegari software CVB- -LINK.

Control function F0 (SW1)
For all applications requiring a handling of the F0 value accumulated during the process, instead of regulating sterilisation based on a fixed time; you may obtain an handling of the F0 value accumulated during the process, through the selection of proper parameters. The software begins calculating the Fo values starting from 100°C.
Datalogger (K82)
This device is used for the digital recording of analog signals, and is installed as on option for printing process data (time, temperature and pressure) on thermal paper. Both the data loaded through the serial port and the data acquired by the datalogger through its sensors (heat probe Pt100 and pressure transducer -- optional), in recording mode, are considered for printing.
Deionizer (T30)
If the network water available for supplying the steam generator is too hard, in order to ensure better performance and less frequent maintenance jobs, we recommend that you install a deionizer. This group is mainly made up of a cartridge of mixed bed resin (8.5 l), that can change its tone based on its progressive emptying. Once empty, the cartridge must be replaced with a new one, containing regenerated resin; lhe replacement takes a few minutes and does not require any specific experience. This model allows the treatment of approx. 750 l of water (with a new cartridge), for an output of 30 l/h; if the water pressure at the inlet exceeds 0.8 bar install a pressure reduced fitted with a pressure gauge on the network, upstream of the deionizer.
Cycle repetition (SW2)
This option allows the repetition of a cycle up to a maximum of 20 consecutive times.
3.1.2.10. Loading/unloading devices
The machine loading/unloading system uses baskets in steel plate, fitted with folding handles (see Figure 3.4).

3.2. SAFETY SYSTEMS

3.2.1. Opening/closing system

Initial system state
Before closing the chamber, until the cover has reached the recommended position, limit switch Z001,checkingthe system correct operation, is kept pressed by a spring, and breaks the circuit for compressed air supply to the seal housing, thus preventing pressurized fluids from entering the chamber.
Starting closing operations
For safety reasons, both hands are required to manually turn the sterilizer cover from position A to position B (see Figure 3.5).
When the cover has reached the position required for closing, limit switch Z001 changes its state and activates the control for compressed air supply to the seal housing.
Closing the chamber
When the limit switch has selected the cover correct position, the operator must press the closing push--button
in order to let compressed air in the seal housing. The chamber starts closing and the cover is blocked.
Sealing system operation
The compressed air pushes the seal upwards and presses it against the cover perimeter, which is lifted from its rest position held by two semicircular brackets.
The seal is pressed against the cover for perfectly closing the sterilizer, thus assuring tightness against pressurized fluids entering the chamber.
Letting fluids into the chamber
Air pressure in the chamber is detected by pressure switch P002. When pressure has reached the set value, the pressure switch warns that the chamber is closed and perfectly tight, thus enabling the process cycle and letting fluids into the chamber.
Starting opening operations
The sterilizer can be opened only when:
-- the process cycle is completed;
-- pressure transducer P001 connected to the sterilizer control system and electro--mechanical safety pressure
-- 23 --
May 2001
#68181 Rev.1
Page 33
switch P005 indicate that the chamber internal pressure and atmospheric pressure have the same value again;
-- the chamber temperature measured by theat probe T001 is lower than the set value, so that the temperature of the liquids to be sterilized in glass containers inside the sterilizer is less than their boiling temperature at atmospheric pressure.
Exhausting air from the seal housing
After the above mentioned steps, the operator presses the opening push--button to exhaust compressed air
from the seal housing.
Opening the sterilizer manually
After automatic air exhausting from the seal housing, the sterilizer can be manually opened.

5.4. POSITIONING THE MACHINE

CAUTION!
When installing the sterilizer, carefully follow the instructions of the installation drawing, as well as this manual’s instructions.
Do not forget that:
* the installation room floor must comply with the required capacity, including the additional
weight resting on its structure, due to scheduled hydraulic tests.
* the connections to the floor must bear a 80°C temperature at least.
* all technical safety measures recommended for seismic areas must be adopted in conformity
with the related regulations.
* All pipes and accessories used for draining the sterilizer service fluids, the lines and fittings for
connecting to the control panel and to other sterilizer components must comply with the regulations of the applicable law.
NOTE
The hydraulic test required by the regulations of the country where the machine is used, t o be performed when the sterilizer has been installed with its user, might increase t he load and reduce the stability of the sterilizer supporting structure. The installation scheme indicates the machine weight and size.
CAUTION!
When installing the machine DO NOT create structural links with surfaces or elements subject to stress or dynamic load outside the sterilizer. Should such links exist in the installation area, please let FEDEGARI know the related problems be f ore buying the machine.
1. Position the machine, so that it rests on a perfectly flat surface;
2. The sterilizer must be placed on a flat surface, near a fume hood;

5.5. CONNECTIONS TO POWER SOURCES AND SERVICE NETWORKS

5.5.1. Hydraulic connections of the users

1. The hydraulic connection to the users is made by means of flexible hoses (see Figure 1.1).
This system also requires:
* hose adapters (ø16 mm) for the purge system;
* quick- -connection ø 6 mm for network water;
* quick--connection ø 4 mm adapters for other users (demineralized water, steam and compressed air).
CAUTION!
It is recommended to connect the sterilizer pur ge system to the drains, taking into account ventilation requirements. Network backflows can result from non--compliance w ith these instructions and the sterilization chamber might be contaminated/polluted. A simple check valve is not considered to be an effective microbiological barrier according to international standards CGMP/CGLP.
To prevent dangers of pollution to the water supply network, it is recommended that suitable back--flow prevention devices and barriers be installed on the intake line of the vacuum pump. To carry out the connections to the users and the trap, all pipes must be kept at atmospheric pressure. Make sure that all fittings feature their specific tag.
WARNING!
The deionized wate r, required with option K10 Steam Generator, must have precise conductivity characteristics. Conductivity can change according to the type of plant by which it is obtained and the maintenance conditions of the plant. With modern plants you can obtain water with a conductivity lower than 5 mmmmS/m, an optimum value for this application. Water with a conduc tivity above 5 mmmmS/m can be used, though, of course, maintenance jobs on the generator will be more frequent. We recommend that you avoid using water having a conductivity above 30 mmmmS/m. Finally, the following information can be summed up:
Recommended conductivity: 2 to 15mmmmS/m, inspecting the generator every year. Admitted conductivity: up to 30 mmmmS/m, inspecting the generator every six months.
CAUTION!
The machine is equipped with safety valves calibrated and checked by FEDEGARI AUTOCLAVI at its factory, at an ambient pressure of 1 bar. If the machine is installed in a place where the ambient pressure is notably different from 1 bar áááá±±±± 0.1 bar), FEDEGARI recommends y ou to have the valves re--calibrated by qualified personnel and/or by the engineers selected for installing the machine, according to the new ambient pressure and before starting the work cycle. This trick ensures safety and proper conditions of use.

WARNING!
The deionizer’s reservoir is designed for a max. pressure of 2 bar. Any higher pressure would cause the reservoir collapse, resulting in uncontrolled water spillage.

5.5.2. Wiring

WARNING!
The sterilizer is delivered with a five--pole feeder cable , featuring a suitable section, without plug and cable terminal.
The customer must complete all machine connections to power supply. These connections must take into account the power required by the machine (see section 3.3.2. as well as the user plant conditions), so that their are fully compatible, in c ompliance with safety rules.
WARNING!
The connection of the sterilizer to the elect rical network requires t he installation of a protection system on the supply electrical pa n el. To ensure safety, the installator should use a magnetothermal switch of a suitable size, based on the equipment’s electrical absorption (cf. see paragraph 3.3.2.).
WARNING!
The equipment has a single serial output for connection to any external equipment. This output is characterised by a net separation through the double insulation of the power and control circuits.
Make sure that the equipment connected to this output is characterised by an equivalent insulation
class.
When carrying out such connections, always take into account the conductor colors inside the cables, according to
IEC standards:
-- BLACK : phases (R, S,T);
-- BLUE : neutral (N);
-- YELLOW/GREEN : earth .
Therefore:
1. IF A VACUUM PUMP IS NOT AVAILABLE: the connection has been completed.
2. IF A VACUUM PUMP IS AVAILABLE: slowly turn the pump and check its direction of rotation to make sure that the
phase sequence is correct. If the pump is rotating in the wrong direction, invert the two phase conductors, as the
only three--phase motor (requiring a correct sequence) has been installed on the vacuum pump.

6.2.9. Control pressure--vacuum gauges
The machine mechanical analog pressure pressure--vacuum gauges (see Figure 6.9) display pressures in the sterilizer pressurized components. One of these devices measures the sterilization chamber pressure. The other one indicates the steam generator pressure, if it has been installed, or the steam supply line pressure. These gauges feature a scale for reading pressure (bar). They continue to detect pressure and vacuum even when the sterilizer is deactivated and the chamber is not operating.

6.2.10. Manual pressure relief valve of the chamber (not available on FVA--HT model)

It is a diaphragm valve (Fig. 6.10) located on the front panel of the machine, near the vacuum--pressure gauges, and connected to the sterilizer chamber. If the machine cannot run in automatic mode, the operator can use this valve for manually checking whether any pressure is left in the chamber on the sterilization process completion. This valve is also used to let out the pressure generated in the chamber when the cover must be opened for new loading operations.
CAUTION !
Risk of scalding! Opening the manual valve may cause hot steam to be expelled from the release duct located at the bottom of the front panel of the machine.

6.3.2. Operating m odes

The interface software has three main operating modes. The first allows to use the machine, while controlling safety from its start until cycle completion (operating mode:
”USE”). The second allows to reconfigure the machine application units (sterilization programs) and to define the general
parameters controlling all activities and functions common to sterilization processes (operating mode: ”CONFIGURATION”).
The third sums up all operating modes allowing to service and/or control, also ”ON LINE”, several software functions, as well as the operating and functional logics (operating mode : ”MAINTENANCE”).

NOTE
The following information on operating procedures, is addressed to the operator authorized to work in the use mode, as well as to the operator/maintenance engineer who, thanks to his training and knowledge of the machine, corresponds to the professional indicated in section 2.4.3.

6.4. OPERATING PROCEDURES

6.4.1. Warnings

Most labor accidents are due to non--compliance with the most important safety regulations. All operators working with the machine must know and comply with the rules of this manual (also refer to section 2.4. ”Safety warnings”).

6.4.2. General information

The most important activities concerning product processing in order to sterilize it is known as ”sterilization process”, or ”sterilization cycle” or ”cycle”.
To carry out a sterilization process, a specific program must be developed on the process controller,which, through its operating system and the above mentioned program, manages a series of operations related to the components and elements controlling fluid temperature and pressure.
Therefore, thermal energy is properly transferred to the batch, according to its physical characteristics. Based on its configuration, the sterilizer exploits one or several sterilization programs which can be selected according to the product to be processed.

6.4.3. Sterilization programs

Every program consists of a sequence of elementary modules named phases. To develop a program the following phase must be sequentially carried out. They control the sterilizer elements so that the sterilization chamber pressure and temperature are compliant with the set functions.
The programs has a set structure of sequential phases, to be enabled by the operator through proper parameters. The phase trend can be modified through the related parameters. A program family can be implemented to meet all requirements, by loading the above mentioned parameters (the ”program parameters”), as well as a series of general parameters concerning activities and functions common to each program.

6.4.3.1. Working parameters
The sterilizer applications (see Figure 6.12, 6.13 and Figure 6.14) consist of a group of specific use programs and of a group, consisting of the same phase sequence, to be used for sterilizing the product.
The above mentioned applications include the following programs:
-- Prg.1 -- Vacuum
It allows to verify the sterilizer vacuum seal. Of course, this program should be used only if the machine is fitted with a vacuum pump unit (option K20).
-- Prg. 2 -- Pressure leak
It allows to check the pressure seal . It can be used only when the sterilizer features a sterilizing filter for air (K51) and the pressurized chamber leak test (option K61).
-- Prg. 3 - - Decontamination
It is fit for sterilizing products coming from environments with microbiologic pollution.
-- Prg. 4 -- Bowie and Dick T
Allows you to check the proper removal of the air from porous batches, as required by European standards for Hospitals EN285. The parameter selection is subject to the machine configuration.

-- Pr g. 5 ¸10 -- Sterilization
The six sterilization programs (5 to 10) have the same structure and can be completely configured by the user. The phase sequence can be modified, by selecting suitable program parameters. Their selection is subject to the machine configuration.
To enable the above mentioned programs, enter their identification number in a specific mask (”SELECT PROGRAM” activated from the main menu).
The system enters the initial cycle phase (Preparation), common to all applications. During this phase, the program does not activate any sterilizer elements or components, thus allowing the operator to complete the sterilizer preparation (product loading in the chamber, cover closing).

Before going on, the program checks the cover system logic, in order to assure that the operations carried out are

compliant with the chamber safety conditions. When running, the program can be stopped before the sterilization process completion only through a manual
emergency control (cycle stop), by an activated alarm (due to a failure occurring during the sterilization process) or when the machine is restarted after a black--out. In this case, the sterilizer enters an ”emergency” phase, providing a wait state which protects the machine, the personnel and any loaded products. The sterilizer is no longer in the emergency state and immediately reaches the cycle final phases (pressure balancing and end--of--phase), by
pressing key
.
The operator will be permitted to execute specific programs (1, 2, 3) and to select some phase sequences of the sterilization programs only if the sterilizer features one or several of the following additional systems (Table 6.10.):

6.4.3.2. Program parameters
The operator can select the desired phase sequence (v1, v2, ...v22) or modify some phase parameters in order to choose the operating configuration required by simply setting proper ”program parameters”.
Program parameters are available in display and adjust mode, when accessing suitable software pages from the main menu (see 6.5.2.).
These 10 pages, one for each program, consist of two types of parameters:
-- Phase selection parameters, allowing to enable the corresponding phase(s);
-- Phase parameters allowing to set target times and values for the phase.
The four tables below describe the program parameters of the sterilizer applications.
In particular, program parameters (5¸10) mentioned in Table 6.16 are supplied with their default values for special
uses:
-- Prg. 5 - - Solid
-- Prg. 6 -- Porous
-- Prg. 7 -- Rubber
-- Prg. 8 -- Closed box for
-- Prg. 9 -- Liquid forced
-- Prog.10 -- Spontaneous--cooling
The meaning of the table fields is the following:
-- NO: parameter identification number;
-- DESCRIPTION: parameter name;
-- FUNCTION: description of the activities managed by the parameter;
-- MIN: minimum parameter value;

6.4.4. Operating phases

The operator manages the sterilization process according to the following main operating phases:
-- Switching on and initial controls;
-- Operation enabling;
-- Product loading;
-- Pro gra m s tar ting ;
-- Process control;
-- Product unloading;
-- Disabling or switching off. To process the product, these operating phases must be carried out in sequence. Of course, to execute these
operating phases, the operator must be acquainted with a series of auxiliary functions, such a:

The calculated F0 is totalled by processing the temperature values measured by the heat probe if the measured temperature is ranging from 100°C to 143, 9°C. F0 value is updated every second, displayed and printed when the cycle is over in order to check the lethal doses applied in the point monitored by T001. F0, value is also used to regulate the sterilization phase through proper program parameters.
6.4.4.4. Opening/closing logic of the cover
Opening
To open the sterilizer:
-- No process cycle must be in progress;
-- Both the pressure transducer connected to the sterilizer control system and the electromechanical safety
pressure switch must indicate that pressure inside the chamber is equal to atmospheric pressure again;
-- The heat probe located inside the chamber measures a temperature lower than the safety set value (this is
possible only if the system parameter ”CHECK FINAL T” has been set);
If the above mentioned conditions have been met, the operator can enable compressed air exhausting from the seal housing. The ”Opened cover” LED on the operator panel will indicate that the cover can be turned to unload the batch.
system
Closing system
Manually turn the cover in order to close it, while pressing the safety lever which releases it. When the cover has reached the closing position, its hooking lever is released. The cover cannot turn and the safety limit switch is pressed. The limit switch allows the system to send the control required to the solenoid valves allowing to supply compressed air to the seal housing of the sealing system. The cover being properly positioned, a control sent by the operator enables the compressed air supply to the seal housing, in order to close the chamber and to lock the cover.
When the chamber is closed, the LED located near the

6.4.5.5. Process control
The operator can check the sterilization process in progress by reading the dedicated page displayed, i.e. the ”process page”.
This page includes and shows information based on two main categories: the first, known as ”control parameters”, supplies useful information (data allowing to identify the program and the phase in progress, set threshold values -­pressure, temperature, time -- as well as their related values, measured and processed in real time inside the sterilization chamber.
The second category concerns information named ”alarm messages” and auxiliary messages.
Control data
During every phase, the control page informs the operator about:
-- the number of the run program;
-- the name of the phase in process;
-- the preset threshold value (pressure, temperature or time), representing the target value of the phase in progress, starting the next phase;
-- the temperature (°) measured in the sterilization chamber by heat probe T001;
-- the pressure (bar) measured by pressure transducer P001;

LOCK !” message, that indicates that the valves involved in the pressure balancing in the chamber (E003 when the pressure in the chamber is below the minimum balancing pressure and E006 when the pressure in the chamber exceeds the maximum balancing pressure) are locked to prevent any microbiologic contamination hazard for the rooms and the products. Therefore, after solving the problem that has caused the decontamination Emergency,the operator can relaunch the cycle, being sure that no contaminated product has been in contact with the exterior of the chamber. If the emergency causes result in the opening the chamber cover, the operator can manually remove the lock on the chamber’s pressure balancing.
