Chapter 2 -†Installation
2.1.桠General Requirement
2.1.1.桠Location Requirements
The BSC needs to be sited in a location that does not compromise the performance of the unit.
As seen in the chart, your cabinet’s internal airflow velocity is relatively low
compared to the airflow disturbances potentially caused by opening a door, a
person walking by or a direct exposure to an air-co nditioning outlet. These
external airflow disturbances can affect the containment of the BSC.
Therefore, the BSC should be located as far away as possible from sources of
airflow disturbance and in an orientation which optimally shields the cabinet’s
airflow from all external airflow disturbances. There should be adequate SOP
in place to minimize events that will affect the performance of the cabinets.
The following requirements should be taken into account:
†If necessary, the arm rest and sash cover can be removed to reduce the overall depth of the cabinet.
Detailed instructions on how to carry out this step can be obtained from your Esco Service
Representative.
†Poor siting of a cabinet can adversely affect performance. A specialist engineer and safety personnel in
your facility should be consulted on correct positioning of the cabinet prior to installation.
†Cabinets should never be sited in line with a doorway, a window that can be opened, or adjacent to a
thoroughfare. Care should be taken to ensure that potential effect of room air diffusers, fans, extractors,
vents, etc. on the BSC are taken into account and any risk of airflow disturbance is appropriately treated
(e.g. eliminated, mitigated) before installation.
†Room air supply diffusers should not be within 1.5 meter (5’) of the front aperture. If there are large
numbers of cabinets in a laboratory this recommendation may be difficult to comply with, but where
diffusers have to be placed in close proximity to a safety cabinet, their discharge velocities will need
to be low.
†The position of a BSC should satisfy the spatial requirements (e.g. vision, lighting and convenience o f
access) of the operator and people working nearby. If the cabinet is installed on a bench top, the
leading edge should slightly overhang or be flush with the edge of the bench top.
†There should not be an open space between the leading edge of the cabinet and the front of the
bench as this may create turbulence in front of the aperture. It also provides an obstacle which could
adversely affect airflow across the cabinet face.
2.1.1.1.桠Position Requirements
Any pedestrian traffic routes, thoroughfares or walkways should be at least 1.0 metre
(3’) from the front of the cabinet, so as to preserve zone undisturbed by anyone other
than the operator.
DOMINIQUE DUTSCHER SAS

3
Class II Biological Safety Cabinets
You should not position the cabinet with either side closer than 30 cm (1’) to
adjacent walls or other similar obstructions. Allow at least 30 cm (1’) clearance on
both sides of the cabinet. There should be adequate space left for cleaning the
sides of the cabinet and for carrying out decontamination procedures. There
should be unobstructed access to the main power supply point(s).
You should not position the cabinet where the distance between the
aperture and any doorway is less than 1.5 meters (5 ’) or the distance
between the side panel and any doorway is less than 1.0 meter (3’). Door
openings cause substantial air turbulence. If the d oor is fitted with air
transfer grills, operator protection factor testing may be carried out to
determine suitable reduced clearance.
Safety cabinets should not be installed in positions where there is a
likelihood of interference from other laboratory equipment. The
distance from the aperture to the aperture of an opposing cabinet,
fume cupboard, etc. should be in excess of 3 meters (9’) for safe
operation.
As with walls, any large obstruction such as a pillar or column projecting beyond the
plane of the front aperture should not be within 30 cm (3’) of the sides of the
cabinet.
You should not position the cabinet in a location where there is an opposing
wall (or other obstruction likely to affect airflow) within 2 meters (7’) of the
front aperture.
The distance between the aperture of the cabinet and the front of a bench
opposite should not be less than 1.5 meters (5’). Containment performance may
not be affected if this distance is reduced, to allow the operator to use the bench
whilst working in the cabinet for instance. You sho uld measure any such effects
using relevant operator protection factor tests to determine safety limits.
Avoid positioning a bench at right angles to the cabinet. While this may reduce traffic in
front of the cabinet, any other person working at the bench is likely to disturb airflow
close to the cabinet.
A projecting bench will help minimize traffic in front of the cabinet and
anyone working at the bench is unlikely to have a significant effect on the
airflow as long as the front of the bench is situated at least 1 meter (3’) from
the side of the cabinet.

2.1.2.桠Preparing For Installation
2.1.2.1.桠Support Requirements
Esco provides a number of support stand options, these are summarized below and further details can be
found in the table at the end of this section. (Note: Some support stands are not NSF certified)
†Fixed height
†Adjustable height
†Telescoping height
†Infinitely adjustable cradle stand
Esco support stand with leveling feet is recommended for safety. It is recommended that the
installation of the support stand be carried out by qualified personnel (contact your Esco
Distributor for assistance). After the cabinet is installed on the support stand, use a level
placed in the center of the work tray to adjust the legs to achieve a level work surface; first
level from left to right and then level from front to back. The NSF approved leg levelers
provide a maximum 50 mm (2”) adjustment.
When installing the cabinet onto existing work surface, ensure that the structure can safely support the
combined weight of the cabinet and any related equipment. Some modifications to the work surface may b e
necessary. The work surface should be smooth, nonporous and resistant to those disinfectants and chemicals
to which the cabinet is regularly exposed to.
2.1.2.2.桠Relocating the Cabinet
Normally BSCs are rarely moved once they are in their ideal positions, but should there be a need to
relocate or repackage the unit, here are some considerations:
†It is recommended that risk assessment is carried out before the BSC is moved.
†Before moving the BSC, remember to decontaminate the cabinet.
†Before moving the BSC, remember to secure all moving parts (e.g. sash window).
†BSC is heavy so please carry out adequate workplace safety assessment before moving the cabinet.
Should only manpower is available (i.e. no suitable equipment), it will usually take 6 or more people
to move a BSC manually.
For repackaging:
†Bolt the BSC to the pallet.
†Strap the BSC body down to the pallet.
†Repackage as necessary. If possible, use original packaging.
†When moving the BSC, use material handling equipmen t and lift the pallet.
2.1.3.桠Environmental Requirements
†Indoor use only.
†Altitude of up to 2,000 meter (6,600 feet).
†Relative humidity between 20% – 90%
†Temperature between 18oC – 30oC (65oF – 86oF).
†Main supply voltage fluctuations up to ± of the nominal voltage.
†Transient overvoltages up to levels of Overvoltage Category II.
†Pollution Degree 2.0
Pollution degree describes the amount of conductive pollutants present in an operating environment.
In pollution degree 2.0, it is assumed that only non-conductive pollutants such as dust are present,
except when occasional conductivity caused by condensation.
2.1.4.桠Exhaust Requirements
The exhaust filter area is susceptible to disruptive air currents or air drafts. A clearance of at least 30 cm (1’) is
recommended between the highest point of the cabinet and the ceiling. If the distance is less than 30 cm (1’),
DOMINIQUE DUTSCHER SAS

5
Class II Biological Safety Cabinets
the airflow alarm system may need re-calibration. For proper exhaust filter leak scanning purposes, a
minimum clearance of 50 cm (1’ 8’’) is recommended.
Esco does not guarantee that this distance would be sufficient. It would have to be verified by your
nearest Esco distributor or your service company.
If you intend to connect your cabinet to an external exhaust system, Esco offers an optional Exhaust Collar for
Thimble-Ducting. Installation requirements and instructions are provided with the Exhaust Collar. (Note:
External Exhaust System Installation is not NSF certified).
2.1.5.桠 Electrical Requirements
†The cabinet should be connected to its own dedicated power outlet(s).
†The power rating for each model is shown in below. Ensure that the outlet is rated accordingly.
Model Power rating
AC2-4E8-TU 230 VAC 50/60 Hz, 8.6 A
AC2-5E8-TU 230 VAC 50/60 Hz, 9.5 A
AC2-6E8-TU 230 VAC 50 Hz, 12 A
†The power cable is located on the right hand side of the cabinet and the cord is 2.5 m long. When
preparing the installation site, try to ensure the outlet is located to the right of the cabinet for ease of
access.
†The cabinet’s maximum voltage fluctuation is ±2% of nominal voltage. Therefore, where voltage
fluctuation is higher, suitable equipment such power stabilizer or UPS with appropriate feature is
recommended.
†Surge protection and UPS are strongly recommended for better protection. Uninterruptible Power
Supply (UPS) with power stabilization function could also be used to eliminate or minimize the voltage
fluctuation seen by the cabinet. Where UPS is installed, it is recommended that the UPS is sized to
enable the BSC to operate for about 20 minutes to provide ample time for the personnel to react to
the power failure.
†A reliable protective earth connection is recommended for better operation and safety.
2.1.6.桠Service Line Requirements
†All service lines should be installed by a suitably qualified and/or certified engineer, in accordance
with all applicable local, state and government regulations.
†Service line attachments should be equipped with an emergency shut off valve that can be accessed
quickly and with ease, should the need arises.
†Check whether there is a need to install pressure regulators to reduce the line pressure.
†Your BSC can accommodate service fixtures on the left or right hand side of the cabinet. Make
allowance for the positioning of service lines when planning the installation site to ensure ease of
access to emergency shut off valves.
2.2.桠Unpacking and Moving your Cabinet
1.†Check the packing labels and delivery note before unpacking to ensure the correct consignment has
been delivered.
2.†Put all packing materials to one side and retain. You may need them to repackage the unit if anything
untoward is discovered with the unit during installation.
3.†If you have purchased an optional support stand this will be attached to the shipping carton of the
cabinet.
4.†Cut the retaining straps and remove the stand (if purchased). This will require at least two persons.
5.†Remove the shrink wrap from the outside of the main carton and dispose of carefully.
6.†If you have not yet done so, remove the retaining straps. Then remove the top of the packing carton.

3.2.1.桠Settings
Users may use the settings menu function to customize the operation of the BSC to meet specific application
requirements. The settings menu can be entered using either FAN PIN or ADMIN PIN.
3.2.1.1.桠Set Clock (Time)
Users can set the time by increasing/decreasing the hour and minute values. The correct time will be
maintained even after the unit is turned off.
3.2.1.2.桠UV Timer (If UV present)
UV timer can be used to switch off the UV lamp automatically after a fixed period. The UV timer can be set up
to 18 hours. By default, the timer is set to 60 minutes. Esco does not recommend leaving the UV lamp on for
more than 60 minutes per decontamination cycle as it shortens the lifespan of the UV lamp. Unless the UV
timer is activated, the lamp has to be switched off manually.
3.2.1.3.桠Measurement Unit
Using this option, the user can select the unit in which air velocity is measured and displayed. The user can
choose between metric (m/s) and imperial (fpm) units.
3.2.1.4.桠Warm Up Time
There will be a warm up period before the BSC is fully functioning upon activation of the unit. This is to ensure
that the sensors, the blower, and the control system are stabilized, as well as to ensure the work zone is
purged of contaminants. The default setting is 3 minutes and the user can set it between 3 to 15 minutes.
(Note: Please note that WHO Laboratory Biosafety Manual (3rd edition) advocates 5 minutes purging time prior to start of
work while US Biosafety in Microbiological and Biomedical Laboratories (5th edition) advocates 4 minutes).
During the warm up period, the user can use the FAN button to turn off the blower, LIGHT button to turn on
and off the fluorescent lamp and MENU button. However, to be able to access the menu, the user needs to
input ADMIN PIN and even then, some sections of the menu (WARM UP and all FIELD CALIBRATION) are still
not accessible for the user. Entering the menu during this time will put the warm up period on pause.
3.2.1.5.桠Post Purge Time
After the user switches off the BSC blower, there will be a post-purge period, to ensure that all contaminants
are purged from the work zone. The default setting is zero minute (disabled) and user can set from 0 up to 15
minutes. It is recommended that BSC is purged for a minimum of 3 minutes after the work is complete.
(Note: Please note that WHO Laboratory Biosafety Manual (3rd edition) advocates 5 minutes post purging time after work
is completed while US Biosafety in Microbiological and Biomedical Laborat ories (5th edition) advocates 4 minutes).
3.2.1.6.桠Set Date
Users can set the date by increasing/decreasing the year, month and minute values. The correct date will be
maintained even after the unit is turned off.
