1Introduction
1.1 EF
The EF is a class II Biological Safety Cabinet. It gives the user the possibility to work safely and
sterile with bioagentia without complete physical barrier between person and experiment (through
work opening (C)).
•Working surface (A) is kept clear of particles by
means of a clean downflow of air.
•Because of the downflow air passed through a
HEPA filter (High Efficiency Particulate Air), the
working area of the cabinet is free of particles.
•This airflow is laminar, the airflow has got no
turbulence and has got a constant air speed.
•Through the work opening (C) air is drawn into
the workspace (inflow), towards the front slots of
the worktop. This protects the personnel against
pathogenic aerosols that might be released.
•The downflow and inflow air is then drawn
through a pre-filter (B) by a fan (E). This fan
blows the air in the correct proportion to the
downflow HEPA filter (D) and the exhaust HEPA
filter (F).
•The extracted air of the cabinet can recirculate
into the laboratory or can be blown into an
exhaust channel.

1.2 EF/B
The EF/B is a class II Biological Safety Cabinet. It gives the user the possibility to work safely and
sterile with bioagentia without complete physical barrier between person and experiment (through
work opening (C)).
•Working surface (A) is kept clear of particles by
means of a clean downflow of air.
•Because of the downflow air passed through a
HEPA filter (High Efficiency Particulate Air), the
working area of the cabinet is free of particles.
•This airflow is laminar, the airflow has got no
turbulence and has got a constant air speed.
•Through the work opening (C) air is drawn into
the workspace (inflow), towards the front slots of
the worktop. This protects the personnel against
pathogenic aerosols that might be released.
•The downflow and inflow air is then drawn
through a pre-filter (B) and a V-shaped HEPA filter
(G) by a fan (E), mounted on a plenum
construction. This fan blows the air in the correct
proportion to the downflow HEPA filter (D) and the
exhaust HEPA filter (F).
•The extracted air of the cabinet can recirculate
into the laboratory or can be blown into an
exhaust channel.
•In case the cabinet is used for cytostatics
production, the cabinet has to be connected to an
external exhaust channel.

Improper use of the cabinet is not allowed.
2.2 Modifications and changes to the installation
In order to operate the installation safely changes and/or alterations shall only be made by Clean
Air Techniek B.V., or shall be made after consultation with and permission in writing from Clean Air
Techniek. If modifications and changes are made on own initiative, without permission from Clean
Air Techniek B.V., the parts of the installation concerned are no longer covered by the warranty.
Clean Air Techniek B.V. cannot be held liable for the consequences of the modifications and the
dangers, which might possibly occur as a result. The modifications mentioned here include the
connection of the installation to an exhaust system.
2.3 Authorized persons
Operating the installation
The cabinet shall only be used by personnel which:
•is familiar with the content, regulations and warnings which are mentioned in this operating
manual;
•is familiar with how to operate the cabinet;
•is familiar with the start up procedure, the stop procedure and Knows how to react in case of
emergency;
•is familiar with the regulations to keep the safety in all circumstances;
•is capable to end a disturbance.
Maintenance and repair general
Maintenance shall only be performed by professional service engineers, who are sufficiently trained
by Clean Air Techniek B.V. to:
•Estimate and avoid the dangers of the installation;
•Estimate the consequences of their actions.
•Before starting maintenance to the installation (mechanical and/or electric) disconnect the
power supply. Pay attention to rotating parts, after switching off the installation the fans will
still rotate for a while.
Maintenance and repair of the electrical installation
Maintenance shall only be performed by professional electro-technical service engineers, who are
sufficiently trained by Clean Air Techniek B.V. when:
•They can estimate and avoid the dangers of the installation;
•They can estimate the consequences of their actions;

EuroFlow EF and EF/B Biological Safety Cabinet

•They are sufficiently informed about the operation of the installation and the operation of the
sub-systems.
2.4 General safety aspects
1. The installation shall never be used for any (micro-) biological or any other potentially dangerous work,
unless the fan is switched into working mode, the sliding window is in working position and there is no
alarm.
2. It is strongly advised not to slide the window out of the working position, during working with the
installation. When it is necessary to increase the work opening, this interruption needs to be as short as
possible.
3. When the installation is not used, the window shall always be closed, with the fan off, or switched onto
power-save mode, to prevent that dust particles etc. from the room can get into the installation (or worse:
material from the installation can get into the room).
4. Always try to limit the amount of equipment in the workspace. Each object in the workspace will disturb
the pattern of the airflow and a large number of equipment may lead to serious disruptions.
5. Materials such as Petri dishes or tissues should, during activities, never cover the slots of the worktop,
since no protection of the personnel can be guaranteed.
6. Do not use a centrifuge in the workspace. Even a small centrifuge is large in comparison with the work
surface and its presence may seriously disrupt the airflow. In addition, all centrifuges themselves create an
airflow, which may fling particles out of the casing.
7. When homogenizers are used in the installation, all reservoirs have to be secured by screw connections,
so that a sudden emission of fluids or aerosols will be avoided. To protect the personnel, glass reservoirs are
suitable for protection. High-speed homogenizers may cause air turbulence, as do centrifuges.
8. Even with the best technology, there may still be a risk that the hands and arms of the personnel get
contaminated during the work. Movements shall be kept to a minimum. Protective clothing shall have tightly
fitting cuffs. The use of hand gloves and over sleeves is recommended.
9. Always use a chair with the correct height. This enables the personnel to have a good view through the
sliding window. User should sit in such a position, that looking under the edge of the sliding window during
the work is not possible.
10. It is important to keep the biological safety cabinet clean. Minor contaminations are not always
immediately visible and could easily be forgotten. This increases the possibility that potentially infective
material is left behind and may cause serious contamination of the interior of the installation or worse.
Regularly clean the worktop, the bottom side, as well as the space under the worktop, in particular. In case
of doubt consider disinfection or contact Clean Air Techniek B.V. about the possibilities.
11. Transport and installation of the cabinet is only allowed for authorized staff. Please contact the
manufacturer or the seller of the products.

GENERAL DANGER
Be careful: high centre of gravity, crossover point.
Never hinge the window, as long as the cabinet is
not placed on the support frame
The cabinet must be installed in a safe way. Clean Air Techniek B.V. supplies an optional support
frame, which is designed for this purpose.
When the cabinet is purchased without a support frame, it is advised to discuss the installation
with the supplier.
3.1 Assembly-instruction
The cabinet has to be placed on the support frame recommended by the supplier. The assembly
needs to be done as specified in instruction underneath.
Assembly support frame
Build the support frame (see Appendix I: Support frames EF & EF/B on page 66 for an explaining
drawing):
•Mount the support yoke (Pos. 1) to the reinforcement plate (Pos. 3);
•Mount (optional) feet support (Pos. 2).
•Item no. 6 is used to position the cabinet to the support frame (see
§3.1 Placing the cabinet on
page 11
).
Placing the cabinet
•Place the cabinet right on the forks of a forklift truck or lifting platform;
DANGER BY INDUSTRIAL VEHICLE
Be careful: Make sure the cabinet cannot slide from
the forks.
•Move the cabinet to the correct height and position, perform this action as precise as possible
above the support frame;
•The weight must be equally divided between the both forks and the cabinet must be horizontal
levelled;
•The cabinet should be aligned with the covers of the support frame.
The two cones on top of the yokes will help aligning;
•Mount the cabinet to the support frame by means of the four inner hexagonal cylinder screws
M8x12 (Pos. 6). See
Appendix I: Support frames EF & EF/B on page 66 ;
•Connect the wire to a grounded socket that is easy accessible.

4.4 Hinge-slide window
The hinge-slide window ( Figure 3, Figure 4, Figure 5 and Figure 6, Pos. 4) is a tightly closing,
manually operated glass window. It can be slid up or down, and opened and closed by means of
handgrips. The window construction contains two guiding profiles with a compression spring. The
spring will push a ball into a hole in the guiding shaft when the window enters the working
position (this working position is also indicated by means of two blue indication stickers).
The window can be hinged, but only in the hinge position, the top hood has to be opened first.
See
§5.2 Top hood/sliding window on page 23 . The hinge option offers the advantage that even
larger objects can be placed inside the working space. It also makes cleaning the working space as
well as the inside of the window easier(see
7.1 Cleaning the installation on page 51 ).
4.5 Top hood
In and behind the top hood ( Figure 3, Figure 4, Figure 5 and Figure 6, Pos. 5) a number of
electrical components are assembled.
•FL lighting
•Operating panel / operating board
•Interface board, including engine control
•Additional option print.
If you wish to check one of these components, you need to hinge the top hood.
To check the interface board, the safety-cover has to be taken away (authorized service personnel
only). Caution! Some of the components are live and therefore carry a risk of electrical shock as
long as the mains plug is connected.
4.6 Worktop
The workroom contains a stainless steel (type 304) worktop ( Figure 3, Figure 4, Figure 5 and
Figure 6, Pos. 6) with a deepened work surface. This deepened work surface is called the safe
working area (for information about the dimensions see
§9.2 General specifications on page 61) .
At the front and the back there are air slits, which are essential to the functioning of the
installation. At the two sides two panels have been placed (See detail Pos. 6)
4.7 Aerofoil
The aerofoil ( Figure 3, Figure 4, Figure 5 and Figure 6, Pos. 7) is used for a better air conduction
and to support the elbow. During work with the cabinet the aerofoil needs to be installed. The
aerofoil is made of coated aluminium for better ergonomics. (less weight and less heat
transportation)
4.8 Plenum-construction
The plenum-construction ( Figure 3, Figure 4, Figure 5 and Figure 6, Pos. 8) divides the air, which
is let in by the fan, between the downflow HEPA filter and the exhaust HEPA filter.

4.9 Drip tray/pre-filter (only EF/B and as an option for the EF)
The pre-filter with drip tray (EF: Figure 3 and EF/B: Figure 5, Pos. 9) is assembled under the
worktop. The installation is equipped with this to protect the interior of the installation against
pollution by coarse materials and to collect spilled fluids. Furthermore the pre-filter will enhance
the life span of the HEPA filter significantly.
4.10 Downflow HEPA filter
The downflow HEPA filter ( Figure 3, Figure 4, Figure 5 and Figure 6, Pos. 10) has a very high
efficiency: Class H14 in accordance with EN1822. After assembling, each filter will be tested
separately according to EN12469:2000, Annex D. Through the service panel the downflow filter
can be reached (Pos. 15).
4.11 Downflow protection
The downflow filter has a build-in protection grid ( Figure 3, Figure 4, Figure 5 and Figure 6, Pos.
11).
4.12 Exhaust HEPA filter
The exhaust HEPA filter ( Figure 3, Figure 4, Figure 5 and Figure 6, Pos. 12) has a very high
efficiency: Class H14 in accordance with EN1822. After assembling, each filter will be tested
separately according to EN 12469:2000, Annex D. Through the topside of the cabinet the exhaust
filter can be reached.
4.13 Support frame (optional)

double suction fans. The “Air Velocity Compensating Microprocessor” controls the fan power for
any disrupting factors such as voltage drops or filter pollution. With an installation with a double
exhaust HEPA filter, an additional fan is built in. The fan regulations are mounted behind the light
hood.

Gas connection
This connection is assembled together with a gas valve. Normally, both the inlet and outlet gas
connections are hose connections, suitable for hoses with an inner diameter of 10 mm. All
connections on the gas supply have to be done with a certified gas hose.
After the connection on the gas supply, the gas connections have to be tested on leakage by a
certified installer.
An electrical gas valve has to be assembled on the gas connection (see Annex A.9 of the EN
12469:2000 standard) as an extra safety precaution. A coupling via the electrical system of the

installation makes sure that the valve can only be operated in work mode and will be switched off
automatically by leaving this mode.
The gas valve switch-function is only visible when the fan in work mode is and there are no
air speeds alarms.

UV light
The UV light is meant for disinfection of the working surface of the safety cabinet.
When the UV light switches on, the FL lighting switches off. The UV light can only be switched on
when the window is closed (window on aerofoil) or when the cabinet is in disinfection mode
(aerofoil lifted up and window at its lowest point), this makes sure the user will not get in contact
with UV-C radiation.
The UV switch-function is only visible when the window is closed.
DANGER FOR BURNING
Avoid direct contact with UV-C radiation. This causes
burns to the skin and eyes.
The UV light can be switched on and off on the display (see
§5.8 Control UV (optional) on page
29
). It is also possible to adjust the UV disinfection, for each day a certain disinfection period can
be defined (see
§5.11 Set up 7 days clock UV on page 31) .
Watch Out!
Do not touch the UV-lamp with the hand and keep the
lamp fat free; otherwise the lifetime will decrease. The
UV-light must be cleaned with alcohol (70%) regularly
(switch off the installation). See
§7.2 Cleaning the UV-
light (optional) on page 53.
