1. OVERVIEW
The safety of this unit with respect to persons, the environment, and the material being processed depends to a great extent on the behavior of those working with the unit.
However, even safe operation cannot rule out risk, particularly with respect to the health of personnel.
This residual risk depends on the work being performed in each instance.
These operating instructions contain important information concerning your safety, the setup
and installation of the unit, as well as for its operation and maintenance !
Please read these instructions carefully before operating these units. Follow all instructions in
order to avoid problems that may result in damage, in particular, in damage to the user's health.
ALWAYS:
Wear protective gear in accordance with any applicable regulations and suited to the degree of risk in-
volved with the task at hand
(clothing, gloves, protective glasses ...).
Implement and follow appropriate hygienic measures.
Each person is responsible for his or her own personal safety and health.
Control Panel

2. NOTES CONCERNING ENVIRONMENTAL SAFETY
Disposal of Shipping Packing Material
The packaging is designed to protect the unit against
shipping damage. Aside from the purely technical aspects of shipping, the packaging materials have been
selected with environmental and disposal concerns in
mind, and are recyclable.
The corrugated cardboard employed is made primarily from recycled paper.
Plastic molded parts (Styrofoam) are free of CFCs.
Wood frames and pallets are made of recycled
wood and are untreated.
The polyethylene foil (PE) is made from partially re-
cycled material.
The strapping is made of polypropylene (PP).
Returning the packaging material to the material
circuit saves on raw materials and reduces waste. In
general, packaging material can be returned to your
dealer.
If you will be disposing of the packaging material
yourself, please contact your local government for
the name of the nearest recycling center.
Disposal of Used Equipment
Prior to their proper disposal, any equipment employed for microbiological work must be thoroughly
disinfected and cleaned. An appropriate confirmation
of this is to be included with the equipment being disposed of.
Used equipment contains valuable materials. You
should not simply take an old unit to the nearest
dump or land fill, but should contact your local government department with respect to the required
disinfection/cleaning procedures and the possibility of
recycling some or all device components and materials.
Disposal of Used Filter Elements
The service life of the filter elements depends primarily on the type of work being performed, the cleanliness of the environment in the are in which the unit is
located, and the device construction.
If the filters must be replaced during operation, the
type and extent of possible contamination must be
considered. Depending on the type and degree of
usage, adequate safety measures for the proper disposal of used filters must be in place prior to replacement.
Only you, as the operator can determine the type
and degree of possible environmental stress, possibly
by also referring to the unit handbook.
In cases of microbiological contamination, the filter
elements must undergo suitable decontamination
measures (sterilization or, at least, disinfection) in order to make them non-hazardous. The proper performance of the selected method is to be confirmed in
writing, and this document is to accompany the filter
elements being disposed of.
The most widely accepted procedure for this is total
room disinfection with formaldehyde vapor, followed
by neutralization with ammonia vapor. Follow all
applicable federal, state, and local ordinances when
carrying out this process (in Germany: TRGS 522).
As a rule, the filters are passivated after this disinfection procedure. There is practically no risk of
contamination with filters employed for safety class 1
and 2 work. For filters employed for safety class 3
work, an additional sterilization step by means of autoclaving the broken up filter material may represent
an additional, practical measure.
Filters treated in this manner can be viewed as domestic waste and can be disposed of accordingly.
The filters can be disassembled for the separate disposal of the filter medium (residual waste) and the
aluminum frames. The modalities of the appropriate
disposal methods may need to be separately worked
out within the context of overall waste management.
For the remainder, all applicable federal, state, and
local ordinances must be adhered to (in Germany:
BImSchG, AbFG ...)
Contaminated filter elements are always to
be treated in the same manner as any other
infectious waste generated by the laboratory.
- CAUTION -
Thermo warns against irresponsible surrender of
possibly dangerous filter waste to persons without the
necessary hazardous waste transport certificates and
permits for the disposal of hazardous waste material.
As the originator, you are responsible for this
waste material.
Noncompliance with the regulated procedures for
waste disposal may make you liable for subsequent
damages.

2. NOTES CONCERNING ENVIRONMENTAL SAFETY
Should you encounter problems in disinfecting - and
thus in neutralizing - the filter elements in question,
please contact us for assistance.
Our Service Department will be happy to present you
with an appropriate offer.
If, aside from the microbiological contamination, the filter elements are expected to
also contain other contaminants (e.g., chemical, toxic, radioactive ...), appropriate
steps must be taken to deal with these prior to disposal of the elements.
Particularly in the case of filter waste that may contain cytostatic agents, it must be treated as hazardous material and be disposed of accordingly.
Energy Consumption
The unit has been designed for continuous operation in order to minimize the risk of contamination.
The ability of the filters to retain materials is only
guaranteed when the unit is operating, that is, when
air is flowing across the filter elements.
Once work in the test chamber has been completed,
the front window can be sealed. The unit then operates in a power-saver mode and is practically si-
lent.
Since the front window is completely sealed in this
mode, it is practically impossible for aerosol materials
in the test chamber to be dispersed into the surrounding atmosphere.
In this operating mode and depending on the ambient
temperature in the setup area, the safety cabinet's interior temperature may increase by up to 10 °C in
this operating mode.
You should therefore never shut the ventilation system off, immediately after completing your work,
so that any untrapped material can still be captured. We recommend waiting approx. 20 minutes of
run-out or reduced continuous operation.
If work is to be interrupted for any length of time,
always turn the test chamber lights out in order to
reduce the unit's energy consumption.
Depending on the agents being processed and their
release in the test chamber, you can also completely
shut down the unit, if it is sealed.
Circulating air mode:
To prevent unnecessary increases in the energy required to heat the laboratory area, we recommend
operating the unit in the circulating air mode. As a
rule, laboratories with a safety classification of L 1
and L 2 do not need to implement any additional
measures to do this.
For laboratories with a safety classification of L 3, a
second exhaust filter (AEF accessory) can provide
additional safety against failure. The required accessory part (AEF) can be retrofitted (HS models
only). After installing the additional filter, the entire
system must be readjusted and re-verified. These
are simple procedures.
The second, supplemental exhaust filter can also
increase the safety level of laboratories handling
cytostatic agents.
The installation of a second, in-line exhaust filter is
not required for series HSP units. The standard prefiltration step performs the same function.
Exhaust mode:
In order to increase safety in case of the failure of
the unit's exhaust filter system, the unit can be connected to the in-house exhaust system by means of
the recommended accessory parts. The air removed from the overall system must be air conditioned before being returned to the working area.
Please note that the unit's safety suffers when replacement air is fed into the work area. This tends
to be the case, particularly where the unit is set up
in a small room.
With respect to energy consumption, this mode is
less economical than the circulating air mode.
All applicable federal, state, and local environmental ordinances must be observed to operate the unit
in the exhaust mode (in Germany: BImSchG).
The adapters required to connect the unit to an inhouse exhaust system are available as optional accessories.
If necessary, surface disinfection of the test chamber
should be performed. Follow the instructions concerning disinfection in the "MAINTENANCE" chapter.
