Further technical details are included in the Annex

1.4 Performance features of this autoclave___________________________________

1.4.1 Fractionating pulsed vacuum procedure _______________________________________________

A fractionating pulsed vacuum method involved the repeated evacuation of the sterilization chamber,
alternating with the introduction of steam in order to ensure the necessary penetration of the items undergoing
sterilization with superheated steam.
This means that even demanding sterilization tasks, involving for example intricate instruments or large
amounts of textiles can be completed quickly and reliably.
Steam penetration can be demonstrated using the established Bowie & Dick Test, for which a special test
program can be implemented.

1.4.2 Programs for sterilization / disinfection________________________________________________

The Vacuklav® 30-B has two sterilization programs, the "universal program" at 134°C: for packed utensils and
the "fast program" for unpacked utensils, as well as a sterilization program for textiles and rubber articles at
121°C, and a disinfection program at 105°C. In addition, it is possible to check at any time that the autoclave is
functioning properly by using the test program for steam penetration (the Bowie & Dick Test Program), as well
as to test for leaks (the Vacuum Test Program).

1.4.3 Separate steam generation __________________________________________________________

The generation of steam by a high-performance unit outside the sterilization chamber makes it is possible to
sterilise large loads of instruments or textiles quickly. It is not necessary to have any pauses between the
sterilization runs, and overheating in the sterilization chamber is impossible.

1.4.4 One-way system/ Conductivity measurement/ Automatic water supply ______________________

The Vacuklav® 30-B operates with a reliable one-way system, in which all the condensate from a sterilization,
including any impurities which this may contain is completely eliminated and purified water used for the next
program run.
An integrated conductivity measurement system monitors the quality of the distilled or demineralised water
used for the steam generation.
For frequent operations, the larger demand for purified water can be met by a water purifier, e.g. MELAdem®47
or MELAdem® 37, which can be directly connected to the autoclave.
Provided the instruments to be sterilized are then also prepared carefully, stains on the load and soiling of the
autoclave itself can be prevented.

and special functions

1.4.5 Electronic Parameter Control (EPS)____________________________________________________

The microprocessor in the Vacuklav® 30-B makes it possible to monitor pressure, temperature and time
continuously during a program by Electronic Parameter Control The overall operating time can then be
optimised according the load and the temperature of the autoclave.
The process assessment and monitoring system in the program control compare current process parameters
with standard process data and monitors the process relative to limit values for temperatures, times and
pressures. This makes it possible to identify faults as they occur, and provides quality assurance for the
sterilization and disinfection processes.

1.4.6 Vacuum drying_____________________________________________________________________

Vacuum drying ensures the best possible drying results for packed utensils.

1.4.7 Pre-heating________________________________________________________________________

By activating the "pre-heating" function, the cold autoclave chamber can be warmed up before sterilization, or
the temperature can be maintained between sterilization runs. This reduces the duration of cycles and
considerably reduces the formation of condensation, thus improving drying results.

1.4.8 Documentation____________________________________________________________________

The electronic memory stores records of the previous 40 programs.
For effective hard-copy documentation and for checking purposes a MELAprint®42 printer can be connected to
print out a record immediately after completion of a program or to print out records from the memory.

2 Installation

When setting-up and installing the autoclave, please consult the separate instructions leaflet "Installing the
Vacuklav® 30-B".

2.1 Setting up the autoclave _______________________________________________

The autoclave should be set up in a dry place which is protected against dust.
The base should be stable, and able to support the weight of the appliance (unloaded weight 43 kg).
The space required by the autoclave can be seen by the external dimensions (as in Section 1.1). A minimum
additional space of 10 cm should be allowed on either side and above the autoclave in order to ensure that
heat can escape.
The electrical power supply should be a separate 230V AC circuit with a 16 A fuse.
The cooling water should be obtained from a mains water supply, to which the autoclave is connected by
means of a water tap or stop cock with a 3/4" external thread. This water supply should be accessible close to
point where the autoclave is set up. (The standard connection pipe supplied is 2 m long).
The disposal of the cooling water outflow requires either a wall-outlet (NW 40) or a sink outflow, and this
should also be situated close to the autoclave (the standard 16 mm connection pipe provided is 2m long). The
outflow must be lower than the working surface on which the autoclave stands, so that the outflow pipe can be
installed without bends and kinks, ensuring a constant downward flow. The autoclave should set-up at a level
which allows easy loading and at which the display can be read clearly without bending.
The autoclave must also be supplied with purified water for steam generation. The distilled or demineralised
water can come either from a storage container (MELAG Art.-No. 244) or directly from the container in which
purchased water is supplied. This should also be situated close to the autoclave (length of feed pipe supplied

1.5m, maximum height difference 1.5 m). If the purified water comes directly from a water purification system
MELAdem®47 or MELAdem®37 (or another purification system) then a storage container is not necessary, but
space must be allowed to accommodate the water purification system.

2.2 Transport ribbons_____________________________________________________

Take the autoclave out of the packaging by means of the transport ribbons. The ribbons themselves are each
removed by undoing the two retaining screws, which must then be screwed firmly back in place without
washers.

2.3 Levelling the autoclave________________________________________________

In order to ensure that condensate can drain out of the autoclave (which is important if it is to operate properly)
the appliance must have be clearly higher at the front than at the back. The autoclave should first be installed
in a horizontal position (this should be checked with a spirit level at the chamber flange) and then the front feet
should be extended by giving them at least five (5) turns.

2.4 Power supply ________________________________________________________

The electric cable of the appliance is plugged into a mains socket rated at 230 V, 50 Hz. The power rating of
the autoclave is 2400 W. In order to avoid overloading the electricity supply, we recommend using a separate
electrical circuit fitted with a 16 A fuse and optionally protected with a 30mA circuit breaker.

2.5 Cooling water inlet connection __________________________________________

The connection for the cooling water inlet at the back of the appliance is connected to the mains water supply
using the pressure pipe supplied (see page 7, Fig. 3.). Make sure that the washers are fitted correctly.
In order to avoid water damage in the event of leaks, we also recommend the installation of a leak detector
("Water-stop", MELAG-Art.-No.:1056).

2.6 Cooling water outlet connection __________________________________________

The connection for the cooling water outlet at the back of the appliance is connected to the drainage system of
the building by means of the outlet pipe supplied (textile-reinforced transparent pipe, DN16). It is important that
the pipe should have a steady downward gradient, without twists and kinks.
When connecting to an existing sink outflow, the use of the double-chamber trap supplied helps to reduce
noise due to water discharging.
When connecting to a separate outflow pipe NW40, a wall-mounted trap should be used (MELAG Art.-No.
37410 ,see Fig. 3).

2.7 Connection of the feed water storage container ____________________________

If the autoclave is to be supplied with distilled or demineralised water from a storage container (see Fig. 3)
then this will be drawn up through the suction pipe. The one end of the pipe is attached to the inlet at the rear
of the autoclave, either directly or by means of the swivel connection. The pipe is then fed into the storage
container until its other end with the inlet filter reaches the bottom.
If you use the MELAG storage container (MELAG Art.-No.: 244) you will find the necessary instructions on the
label. This container has a volume of 11.5 litres, enough for an average of 25 sterilization cycles.

2.8 Connection of a water purification system ________________________________

The autoclave can be connected directly to a water purification unit which provides the demineralised or
distilled water required (see page 39, Fig. 4). Instead of connecting the feed water inlet to a storage container,
it is simply connected directly to the water purification unit.
The reverse-osmosis systems MELAdem®47 and MELAdem®37 are ideally suited to provide the quantity and
quality of water needed for the Vacuklav®30-B.
Detailed instructions on the installation of these water purification units are provided in their operating
manuals.
When connecting water purification systems from other manufacturers it is very important to ensure that they
are able to provide sufficient amounts of water at the required purity. You are generally advised to consult
MELAG first.

3 Initial start-up

3.1 Printer connection/ Initialisation (optional)________________________________

3.1.1 Connecting the MELAprint®42________________________________________________________

The autoclave can be connected to an external printer, the MELAprint®42. This is not supplied as standard
with the autoclave.
In order to connect the printer to the autoclave follow the description in Section 6.3.1.1.1.

3.1.2 Initialisation of the printer / Setting up immediate print-out ________________________________

Initialise the external printer (registering with the processing unit of the autoclave) as described in Section

6.3.1.1.2. In order to select the immediate print-out option, which means that a record of each sterilization is
printed out automatically as soon as it has finished, proceed as described in Section 6.3.1.3.

3.2 Vacuum test__________________________________________________________

In order to check the operation of the autoclave in the course of the initial start-up, after long periods without
being used, or after moves, as well as periodically during routine use, a vacuum test should be carried out to
check for leaks.
The vacuum test should be carried out as follows, preferably on the cold autoclave:

If the leakage rate is above the limit value, then the display (and the print-out) will also show "Test
unsuccessful". In this case, follow the instruction in Section 7.3.

3.3 Test run _____________________________________________________________

In order to check the operation of the autoclave under realistic conditions, a test run should be carried out with
the "Universal Program, 134°C wrapped" and a relevant load. After loading the autoclave and selecting the
program with the "Program" button, sterilization is started by pushing the "Start/Stop“ button. If the program
runs correctly, the following message will appear on the display (see Section 4.6 ):

with the values for the maximum values for pressure and temperature. If the immediate printout option has
been selected for an external printer a record of the program run will be printed.

3.4 Installation record ____________________________________________________

As documentation that the autoclave has been set-up properly, an installation record should be produced by
an authorised person and a copy sent to MELAG. This is important in the event that you wish to make claims
under warranty provisions.

3.5 Safety instructions ____________________________________________________

• When opening the door, particularly after interrupting the drying process, residual steam can escape from

the autoclave chamber.

• After opening the door, do not touch any metal surfaces - these will be hot! Danger of burns. Always use

the tray lifter to remove trays, or wear suitable hand protectors when taking out other items

• We recommend the installation of a water leak detector (see installation details Section 2).

• If you intend to install a water purification unit from another manufacturer, then consult MELAG before you

do so.

• The appliance is not suitable for sterilising liquids.

• Under current VDE-regulations, this appliances is not suited for use in areas where there are risks of

explosion.

• The appliance must only be serviced and repaired by MELAG or by its authorised representatives

(specialist dealers or customer services) using only original parts and following service instructions.

• Before opening the housing always disconnect from the mains power supply!

• In order to ensure effective sterilization with the autoclave observe the instructions in this operating manual,

and in particular ensure that the loading of the autoclave is appropriate for the program selected.

4 Instructions for all sterilization procedures

4.1 Electricity and water supplies___________________________________________

4.1.1 Cooling water and purified feed water _________________________________________________

The autoclave automatically monitors the availability of cooling water and purified water, as well as the quality
of the distilled / demineralised water before starting a program.
In order to allow an immediate program start and to avoid error reports or interruptions of programs (see
Sections: 7.3 and 7.4) :

• Before the first sterilization at the start of the working day, check that the water supply is turned on (stop

cock)

• If purified feed water is drawn from a storage container, check the water level, and if necessary fill up with

purified water of appropriate quality (see Section 8.3.2)

• If the feed water is drawn directly from a MELAdem

®

47 water purifier, check that its water supply is turned
on in good time (this may be up to an hour before starting a sterilization program), if the water supply has
been turned off over night, for example.

4.1.2 Power supply _____________________________________________________________________

Switch on the power using the switch on the front of the autoclave (bottom right). About 15 seconds after the
message "Please wait Door release“ the appliance is in the start status :

4.2 Loading the autoclave_________________________________________________

It is of crucial importance for effective sterilization and good drying that the autoclave is loaded properly:

Tray rack

For the Vacuklav® 30-B there are 2 types of tray rack:
Type "A" (MELAG-Art.-No.: 40231) for up to 6 trays and
Type "B" (MELAG-Art.-No.: 40234) for up to 4 trays or 4 standard tray-cassettes.
Both types of tray rack are also suitable for the MELAG-sterilization containers Type 15K,M,G; Type 17 K,M,G;
Type 17R; Type 23R, Type 28 M, Type 28G).
Normally, the autoclave should be used in conjunction with a tray rack, since this ensures that steam
penetration and drying are as good as. In exceptional situations (e.g. when using sterilization containers from
other manufacturers), and after consultation with your specialist dealer or with MELAG, the tray rack can be
removed and the container can be placed directly in the autoclave chamber.

Trays

Trays for objects which are to be sterilized must be perforated, in order to allow condensate to run away.
MELAG-trays are recommended. If you use dishes or trays without perforations, then the objects being
sterilized will not dry properly.

Enclosed sterilization containers

Enclosed sterilization containers must be perforated on at least one side (preferably underneath) or must have
valves, in order to ensure that steam can penetrate and condensate can run out. All MELAG-sterilization
containers meet these requirements with perforations on two sides and filter-cloth- inlays.
Sterilization containers which only have perforations on the top only allow limited drying.
If sterilization containers are stacked in the autoclave, it is important to ensure that the perforations are not
blocked.

Transparent sterilization packaging

If you use transparent sterilization packaging, such as MELAfol® , then the items should if possible be stood
vertically on the tray, or sterilized in foil holders (MELAG-Art.-No.: 238). They should never be laid flat one on
top of the other.
If seals split open during sterilization it may be necessary to increase the length of the sealing impulse or to
use a double-seal.

Standard tray- cassettes sealed in MELAfol® (250 mm wide) must be taped and clasped additionally to ensure
that the side-seals do not split open.

Multiple wrapping

The pulsed vacuum method means it is possible to use multiple wrapping.

Maximum loads

Loads should not exceed 5kg of instruments or 2kg of textiles.

Mixed loads

If mixed loads of textiles and instruments are to be sterilized, then as far as possible the textiles should be
above the instruments and direct contact with the instruments should be avoided.
Inclusion of textiles and instruments in the same sterilization container is not desirable.
Textiles should never come into direct contact with the walls of the chamber.
If different types of packaging are included in a load, then:

• Instruments and sterilization containers should be at the bottom

6. Drying phase
After pressure release the drying phase begins.
At this point it is possible to stop the program without this leading to a fault being
reported, since the sterilization itself is now completed. However, with the exception of
the "Quick Program", the drying phase should be allowed to run to completion.
