4.2 Safety system
The safety system comprises a combination of protective and alarm systems
that ensure maximum personal and material protection.
Safety systems:
• Vacuum-sealed air system
A vacuum-sealed air system in combination with HEPA filters for downflow
and exhaust air forms the basis of the safety system for personal and material protection.
• Personal protection
Air aspired from the exterior along the entire working opening at a constant
high velocity prevents that:
• agents may leak through the working opening of the chamber.
As the exterior air pressure around the unit exceeds the pressure of the internal air system (vacuum sealing), it is ensured that:
• agents cannot be released to the exterior in the case of a leak in the
cabinet housing.
• Material protection
A steady airflow within the air system ensures that:
• a constant downflow allows the HEPA filters to remove contaminants
so that the samples are always surrounded by ultrapure air,
• harmful particles are not carried over through the sample chamber
(protection from cross-contamination).
• HEPA filters
The downflow (i.e. the air circulating within the device) and the exhaust air
(air that is released to the exterior) are cleaned by HEPA filters (HEPA = High
Efficiency Particulate Air Filter).
For version KSP, a prefiltering system is used to increase the filter efficiency and to protect the exhaust air and downflow systems.
• Safety lockout
To protect from UV radiation, the optional UV disinfection routine can be run
only if the front opening is closed. During UV disinfection, the front opening
safety lockout is activated and prevents harmful UV radiation from being
emitted from the sample chamber.
Operating Instructions Safety Cabinet HERAsafe KS / KSP
Warning system:
• Airflow monitoring
Airflow monitoring determines the velocity of the airflow in the sample chamber
as well as the inflow velocity of the air aspired from the exterior through the
working opening. As soon as airflow velocities move above or below a specified safety value, a signal is transmitted to the alarm system.
• Visual and audible alarm system
The warning system constantly monitors the safety-relevant device functions:
• Inflow velocity of the air aspired from the exterior,
• downflow velocity,
• working position of the front window.
If the warning system detects changes to one of these device functions, it
issues:
• an audible and a visual alarm signal.
17
Page 18
Operating Instructions Safety Cabinet HERAsafe KS / KSP
4. Unit description
• Position monitoring
The position sensors monitor the position of the front cover as well as the movement of the front window; it will indicate when the front window is in the working position.
• Kendro Performance Factor
The Kendro Performance Factor (PER) is a value that indicates the safety state of the safety cabinet. This value is
calculated from data determined by the safety system and
from values captured empirically by service personnel during
safety checks. This data is entered into a parameter list of
the control software and interconnected. The result can be
indicated by the display.
4.3 Filter system
Version KS:
Fig. 4: The filter system consists of two HEPA filters [2] and
[5] for the circulating air and for the exhaust air and of a coarse
filter for the aspired air.
HEPA filters: Room air [10] is drawn into the sample chamber through the working opening. In the air duct, room air and
the downflow within the chamber [7] are then blended to make
up the blend air [9]. The blend air is then:
• filtered proportionally by the downflow filter [5] and supplied as ultrapure air [6] evenly into the sample chamber of
the device,
• filtered by the exhaust air filter [2] and released as ultrapure air [1] to the exterior of the device.
Inlet air protection: The air duct between the sample chamber
and the device plenum has an inlet air protection [8] below the
working surface to prevent coarse particles from entering the
plenum where they may impair blower [3] und [4] and filter
functions.

Page 19
4. Unit description
Version KSP:
Fig. 4b: The filter system consists of a set of HEPA prefilters
[10] (the number of filters depends on the sample chamber
width) and two HEPA filters [2] and [5] for downflow air and
exhaust air.
HEPA prefilters:
The compact size of the filter inserts allows filter replacement
with minimal contamination hazard. The use of the prefilters
protects the downflow and exhaust air filters considerably.
The filter inserts used are HEPA filters of Class H14 (according to DIN EN 1822). Alternatively, activated carbon filters can
be inserted into the housing to protect from smells.
Room air [11] is drawn into the sample chamber through the
working opening. In the air duct above the prefilter, room air
and the downflow within the chamber [7] are then blended to
make up the blend air [8]. The blend air is then:
• aspirated into the prefilter [10], filtered and fed into the air
duct [9].
Operating Instructions Safety Cabinet HERAsafe KS / KSP
HEPA filters: From the air duct, the prefiltered air is:
• filtered proportionally by the downflow filter [5] and supplied as ultrapure air [6] evenly into the sample chamber of
the device,
• filtered by the exhaust air filter [2] and released as ultrapure
air [1] to the exterior of the device.

4.4 Controls and display
Fig. 5: The safety cabinet is equipped with two separate control
elements that operate independently of each other:
• remote control [3],
• pilot switch [1].
The status indicators of the display [2] indicate control operations initiated with the control elements.
Remote control: All device functions can be activated and
deactivated easily using the remote control.
Pilot switch: Use to control all basic functions required for the
operation. This switch allows you to operate the safety cabinet if the remote control is not operational or available.
Fig. 6: The display [1] can show text or numeric values and
has 12 LEDs [2] and [4] to indicate the current operational state
of the unit.
The display module also houses the sensor system for the remote control. The pulses transmitted are best received by the
sensor if the distance A between the remote control [5] and the
sensor [3] does not exceed 1m and if the radio signal beam
does not deviate more than 15° horizontally.
The transmission range of the remote control also depends on
the battery state of charge.

9. Cleaning and decontamination
9.1 Decontamination procedure
Several procedures can be applied for decontaminating the safety cabinet. Which
procedure is selected, depends on:
• the potential risk imminent in the agents,
• the degree of purity required by an experiment or by a work process.
Possible decontamination procedures:
Wipe/spray disinfection: is the standard disinfection procedure for cabinets
used for microbiological experiments.
UV disinfection: is particularly suited as an intensifying additional disinfection
after a wipe/spray disinfection.
Sterilization with steam: can be used for treating the removable stainless steel
components. Examples of autoclavable components are the bezels of the UV
lamps, the workplate or workplate segments and the armrests.
Operating Instructions Safety Cabinet HERAsafe KS / KSP
Disinfection with formaldehyde: can be performed if a sterile scmple chamber is required for the work process. This sterilization procedure is mandatory:
• when filters are replaced,
• when the device is shut down,
• when the device is discarded.
9.2 Wipe/spray disinfection
The wipe/spray disinfection is performed in three stages:
• Predisinfection,
• cleaning,
• final disinfection
Recommended disinfectants:
NOTE – Compatibility!
Chloride-containing disinfectants may damage
some surfaces; use only chloride-free disinfectants or a disinfectant with a low enough chloride content to have been proved harmless for
stainless steel finishes!
Disinfectants with an alcohol content of more
than 70 % may cause embrittlement of plastic
components after extended esposure. Use only
disinfectants with a low alcohol content. When
using a disinfectant with an alcohol content
of more than 70 %, the release limit of 200 g
within 2 hours must not be exceeded.
Also suited are disinfectants based on quaternary ammonium compounds.

Operating Instructions Safety Cabinet HERAsafe KS / KSP
9.4 Disinfection with formaldehyde
Procedure:
For gas disinfection, formaldehyde is evaporated in the tightly sealed sample
chamber. The quantity of the formaldehyde used depends on the sample chamber
volume of the cabinet version to be disinfected (see Technical Data).
Per cubic meter of sample chamber volume, at least 5 g formaldehyde must be
evaporated with 20 ml water (corresponds with 25 ml of a 20 % formaldehyde
solution). The formaldehyde evaporates immediately when its boiling point is
reached. The required reaction time is at least 6 hours.
After the required reaction time, the formaldehyde should be neutralized by evaporating a 25 % ammonium solution (10 ml per cubic meter of sample chamber volume).
Ambient conditions and accessories:
The temperature at the cabinet location should be approx 21° C, the relative
humidity should be between 60 and 85 %. To evaporate the solution, a heating
device with a container is required.
NOTE – Disinfection procedure!
A disinfection with formaldehyde must be
performed in accordance with the specifications of NSF 49/1992, Annex G.
As this procedure has considerable risks, it
must only be performed by specially trained
