Description
4.1
Working principle
The microbiological safety cabinet is a modified exhaust cabinet with a turbulence-free (laminar)
vertical displacement flow of clean air in the work chamber protecting the product against particle
contamination. During operation the front window is partly open and the in-going airflow prevents
the escape of particles from the inside of the work chamber thus protecting the operator and the
environment.
4.2
Air filtration
The ScanLaf Mars-Mars Pro main filter and exhaust filter of ScanLaf Mars-Mars Pro and the
prefilter for Mars Pro are all high-efficiency HEPA filters.
4.3
Air velocity monitoring
The low turbulence vertical flow and the exhaust flow are monitored by means of air velocity
sensors.
Any deviation from safe conditions will be indicated optically and acoustically.

Work Rules
9.1
Before start-up
The cabinets may only be operated at temperatures between 15 °C and 35 °C, at maximum
80% relative humidity, and at normal air pressure.
All cabinets are developed and produced for use in clean environments.
They must not be operated outdoors or in environments with extreme air pollution. The safety
cabinets are not intended to filter vapours containing acids or organic solvents. The safety
cabinets must not be used as a fume hood.
Approximately 15 minutes before any work in the cabinet, the fan of the unit must be
switched on at normal velocity.
The work chamber and the front- and side windows are to be carefully cleaned and
disinfected. Use an ethanol solution or similar. It is recommended to use special lint-free
material. Do not use explosive disinfectants. See also section 10.
Objects and appliances must be carefully cleaned or disinfected before being introduced into
the work chamber. Do not bring in writing utensils, packing material, etc.
The front window is positioned in working position and kept in that position during the entire
work process.
Necessary appliances for use during work must be placed within easy reach.
Secure the appropriate protection of the operator as well as the product (e.g. clothes, gloves,
etc.).
9.2
While working
Caution
Important for work with environmentally harmful substances!
Do not perform work while the fan is running at reduced speed.
The front window must be in work position.
Place the product behind the perforated area of the work surface.
Work with calm, smooth movements.
Never overload the work chamber.
Reduce the number of transfers into and out of the work chamber.
Avoid equipment with high heat emission.
Avoid a cabinet location where personnel frequently pass avoid draughts.
Caution
The efficiency of the laminar airflow in the work chamber is essential for personnel
and product protection. Negative influences of the flow conditions must therefore be
avoided.
They are primarily raised due to:
Rapid movements of the operator s hand, arm, or body both in and in front of the work
chamber.
Covered perforations in the table top, both at the front and the back of the work chamber.
Large objects and apparatus.
Devices making rapid movements, e.g. agitators, centrifuges.
Caution
Do not damage the air distributor, the prefilter (Mars Pro) or the main filter in the
ceiling of the work chamber by mechanical objects or heat sources, otherwise the
microbiological safety is no longer ensured.

Supervision – Alarm
The cabinet safety is constantly supervised so that any deviation from safe conditions or any fault
in the supervision system will be indicated immediately.
Safe conditions are indicated by a green LED light in the button for fan at normal velocity.
Unsafe conditions will be indicated both acoustically and visually by red flashing LED light.
The alarm will be initiated if
The vertical air velocity inside the work area is outside the limits.
The air volume exhausted is below the limits.
The fan is running at reduced velocity.
After a power failure.
Optionel 3rd sensor: A pressostat mounted in the exhaust channel – the pressure drop is too
low.
By activating the alarm
when the cabinet runs at reduced speed the red LED will change
from flashing to constant light.
The alarm will be silenced off when the fan is running at normal velocity, all conditions are safe, or
the cabinet is switched off.
(The whole display can be flashing if there is an alarm – this setting is done as a default in alarm
setting).
10.4
Optional mounting of PIR sensor.
If the set-up of the cabinet has to be automatic – it means the cabinets is ready to work when the
operator stick the arms in the work chamber:
In this case a PIR sensor can be mounted – let the cabinet run at full speed for defined time – as
long as there are movements. If no movements it will stop after preset time from 30 seconds.
In order to ensure the clean environment inside and that the cabinet instantly provides operator
safety – the cabinet has to run at constant reduced speed – in the working hours (Programmable
through the Autostart – menu).
10.5
Setting of light
The light setting of the cabinet upon alarm can be set in 3 different alternatives:
Light always on when blue light button is activated.
Light always on when blue light button is activated and in full speed – if reduced speed is
pressed the light turns out.

Cleaning and decontamination
Cleaning must be done daily after work in order to obtain a safe working environment.
The cabinet should be kept clean and free from unnecessary equipment.
The interior should be swabbed with a suitable disinfectant with the right biological spectrum after
use. Phenolics, quaternary ammonium compounds and aldehydes can be used for disinfecting
these surfaces. Recommended disinfectants are 2% (vol.) gluteraldehyde or 15% (vol.)
formaldehyde. Use alcohols on caution because of the risk of fire.
DO NOT USE ANY COMPOUNDS CONTAINING HYPOCHLORITE SOLUTIONS, as this will
damage the stainless steel.

Maintenance
Caution
Every 5000 operating hours or at least once every year the cabinet has to be
inspected and tested.
Caution
Before repair work is carried out inside the contaminated and/or infected cabinet and
prior to filter replacement and upon change of location, proper cleaning and
disinfecting by the operator is required. The lab Manager/Safety Manager must
confirm this in writing to service personnel. For the appropriate form, refer to section
14.
After completion of work, tests are required according to the standard.
Leakage test of pre, main and exhaust air filter.
Test and adjust air velocities and alarm settings in the vertical flow inside the work chamber
and the horizontal in-flow in the work opening.
Test of air flow patterns.
General function and safety tests in accordance with local requirements. For this purpose we
recommend a maintenance agreement.
Before work on the electrical system, disconnect the power.
Fuses are accessible and situated on top of the cabinet (authorized person only).
All maintenance and repair work performed, as well as filter replacements and required tests, must
be documented in a test book. See section 13.
12.1
Filters

Note
The HEPA filter is very fragile. Even a light touch on the filter surface may damage
the filter.
In order to avoid any possible harm, it is recommended that while changing filters the service
technician wears a mask with filter of HEPA quality. (H14 or better).
The used filters must be placed in special bags for biohazard waste immediately after removal. The
special bags should be handled as toxic material and sent for destruction as the normal toxic waste
from the lab.
12.2
Replacement of the HEPA filters
When the main- or the exhaust HEPA filters need to be replaced on Mars-Mars Pro, due to
leakage or to higher pressure drop, it is recommended that both filters are replaced at the same
time.
When the prefilter needs to be exchanged on Mars Pro, the main and exhaust filters does not need
to be replaced.

on the right-hand and the left of the cabinet below the plastic stoppers) and remove
the squads.
Now lift up the frame and the pressure plenum and carefully remove the main filter, place
the filter in a plastic bag and treat it as biohazard waste.
Now release the anchors of the exhaust filter by following the steps listed: Remove the
rectangular steel frame placed on the cabinet’s ceiling. Now the exhaust filter is accessible;
lift it up and place it in a plastic bag for biohazard waste. Insert the new filter by performing
the reverse operations for its installation.
Filters must be provided with gasket on both sides.
Before installing the new filters, the filter frame must be cleaned very carefully.
The new filters must correspond to make and the model indicated on the tags placed on the
removed panel.
A ROUTINE TEST IS COMPULSORY AFTER THE REPLACEMENT OF THE FILTERS
The prefilters on Mars Pro are easily exchanged while the cabinets are running under full speed to
ensure full operator and environment protection. The prefilter cassettes are taken up and the
prefilter are carefully placed in plastic back and closed safely. Before installing the new filters, the
filter frame must be cleaned very carefully. Be careful not to harm the prefilters.
The new filters must correspond to make and the model indicated on the tags placed on the
