Normal operation
nThe sterile filter is no longer effective if it has become wet. Stop using the sterile filter and replace it.
nDo not replace the sterile filter during a program run.
Program abort
nPlease observe that opening the door following a program abort can lead to hot steam and hot water leaving the
sterilization chamber.
nObserve the instructions shown on the display of the device. Sterilize the affected }load after re-wrapping.
Removing the sterile material
nNever use force to open the door.
nUse a tray lifter to remove the tray. Never touch the sterilized equipment, the chamber, the mount or the inside of the

Intended use
The SteriHero Vet steam sterilizer is intended for use in veterinary medicine. The steam sterilizer is designed as a small
steam sterilizer according to }EN 13060. It uses the fractionated vacuum process to guarantee effective steam
penetration of the material with saturated steam. It is suitable for reprocessing instruments and materials that may come
into contact with blood or body fluids during treatment. The steam sterilizer is not intended for use on patients or in the
patient’s environment and is not intended for the sterilization of liquids. Typical user groups are veterinarians, trained
staff and service technicians.
WARNING
Any attempt to sterilize liquids can result in a }delay in boiling. This can result in burns and damage to
the device.
nNever use this device to sterilize fluids. It is not licensed for the sterilization of fluids.
Sterilization procedure
The steam sterilizer sterilizes on the basis of the fractionated vacuum procedure. This guarantees the complete and
effective wetting/penetration of the sterilization material with saturated steam.
The steam sterilizer uses integrated steam generation to generate sterilizing steam. Steam is generated in the
sterilization chamber upon program start. This establishes a pre-defined pressure and a set temperature. The
sterilization chamber is protected against overheating. You can sterilize large quantities of instruments or textiles directly
one after each other, thereby achieving excellent drying results.
Automatic preheater
If the preheater is activated, the cold sterilization chamber is heated up to the preheating temperature of the particular
program before program start, or this temperature is held between two program runs. This reduces program times and
reduces the accretion of condensation. This results in improved drying results.
Type of the feed water supply
The steam sterilizer works with a one-way }feed water system. This means that it uses fresh feed water (}demineralised
or }distilled water) for every sterilization procedure. The quality of the feed water is subject to permanent monitoring via
integrated }conductivity measurement. If combined with a proper preparation of the instruments, this serves largely to
prevent stain accretion on the instruments and soiling of the steam sterilizer.

Program runs
A reprocessing program runs in three main phases: the air removal and heating up phase, the sterilization phase and the
drying phase. After program start, you can follow the program run on the display. It shows the chamber temperature and
pressure as well as the time until the end of drying.
Program phases of a standard sterilization program
Program phase Description
1. Air removal and heating
up phase
Air removal
In the evacuation phase, the mixture of air and steam is repeatedly evacuated and
steam is generated in the sterilization chamber. This efficiently removes air from the
sterilization chamber and prepares the load for sterilization. This procedure is also
called the fractionated vacuum procedure.
Heating up
The continued steam generation into the sterilization chamber leads to an increase
in pressure and temperature which continues until the program-specific sterilization
parameters have been reached.
2. Sterilization phase Sterilizing
If the pressure and temperature correspond to the program-dependent nominal
values, the sterilization phase begins. The corresponding process parameters
(pressure and temperature) are held at sterilization level.
3. Drying phase Pressure release
The sterilization phase is followed by pressure release from the sterilization
chamber.
Drying
The sterile material is dried using a vacuum (vacuum drying).
Ventilation
Upon program end, the sterilization chamber is filled with sterile air via the sterile
filter and adjusted to the ambient pressure.
Program phases of the vacuum test
Program phase Description
1. Evacuation phase The sterilization chamber is evacuated until the pressure for the vacuum test has
been reached.
2. Equilibration time An equilibration time of 5 min will follow.
3. Measurement time The measuring time is 10 min. The pressure increase within the sterilization
chamber is measured during the measurement time. The evacuation pressure and
the equilibration time or measurement time are shown on the display.
4. Ventilation The sterilization chamber is ventilated after the end of the measuring time.
5. Test end The display shows the test result and the leakage rate.

Safety equipment
Internal process monitoring
An independent }process evaluation system (safety controller) is integrated in the electronics of the steam sterilizer. It
compares the process parameters (such as temperature, time and pressure) during a program run. It monitors the
parameters in terms of their threshold values during control and regulation and guarantees a safe and successful
program run. A monitoring system checks the device components of the steam sterilizer for their functionality and their
plausible interaction. If one or more parameters exceeds pre-determined threshold values, the steam sterilizer issues
warning or malfunction messages and if necessary, aborts the program. In the case of a program abort, follow the
instructions on the display.
The steam sterilizer uses an electronic parameter control. This enables the steam sterilizer to optimise the total operating
time of a program depending on the load.
Door mechanism
The steam sterilizer constantly checks pressure and temperature in the sterilization chamber and prevents the door from
being opened when over-pressure has built up.
Automatic monitoring of the feed water
The quantity and quality of the }feed water is automatically checked before every program start.

Load mount
Note the following depending on the use of the accessories:
A spring clip (pos. a) is located on the rear panel of the
sterilization chamber to fix the mount. When using an
APlus mount, slide the mount (pos. b) into the
sterilization chamber to its fullest extent, until the mount
snaps into the spring clip audibly and noticeably. To
remove the mount, pull it out of the spring clip with both
hands.
ab
The APlus mount can be used for sterilization of soft-
packed goods (e.g. in MELAfol) on trays. A combination
of trays (short or long) can be arranged on up to five
levels or, turned by 90°, three MELAstore Box 100. The
mount is fixed in the device and remains in the
sterilization chamber during loading and unloading.
Up to two MELAstore Box 200 can be sterilized directly
in the chamber without a mount.
For detailed instructions on the use of the accessories and their combinability with different load holders, see the
document “User manual Accessories for small steam sterilizers”.

good ventilation.
The steam sterilizer works with a cooler on the rear of the device. The function and life-span of the steam sterilizer can
be compromised if heat dissipation via the cooler is restricted in any way. The steam sterilizer may only be installed if
sufficient air circulation can be guaranteed.
