Section 1
Description of the cabinet
Working principal
Class II Microbiological Safety Cabinets are designed to provide a high level of protection for the
operator, environment and sample. The cabinets work on a recirculating principal with
approximately 70% of the air drawn from the working area being recirculated. The remaining 30% is
exhausted via single or double HEPA filters back to the laboratory. An inflow velocity of
approximately 0.7m/sec. at the working aperture provides operator protection. The recirculated air
at a downward velocity provides sample protection from the laboratory environment and cross
contamination between samples.
Features
ISO Class 4 clean air
Compliant to BS EN 12469:2000
Advanced electronic control and monitoring system
Double or single outlet HEPA filter on recirculating version
HEPA filters with integral diffuser/laminator
Electrically operated sliding sash with integrated obstruction detection safety system
Timed start-up feature –Cabinet can be optionally set to start up unattended
Timed standby feature –Cabinet can be optionally set to standby unattended
Passcode protected start-up/shut down –Prevents unauthorised cabinet operation
Easy clean glass system
Toughened glass side windows
Internal auxiliary electrical appliance sockets
Low energy LED lighting
Stainless steel removable worksurface trays
Low overall height –fits most rooms
Ports for connection of VHP systems
UV decontamination lamp
Cabinets can be provided with a range of options, such as Gas, CO2 and Water supplies, Formalin

SECTION 2
Installation
Important handling procedures
The cabinet should be handled with care during the transportation and siting process. The
cabinet is shipped with foam blocks and tape to secure and protect it during transit. These should be
removed once finally sited and before turning the cabinet on for the first time. To remove, open the
front cover. The sash will rise slightly and enable the foam to be removed.
Location
The cabinet should be sited in a draught-free location i.e. away from door entrances, corridors,
ventilation supply points etc. which will affect the airflow within the work zone as recommended in
BS5726:2005. The cabinet should be fully tested and commissioned by suitably qualified persons
before being put into service.
If the cabinet is moved or relocated it should be recommissioned.
Ducting connection (optional)
The cabinet can be supplied or fitted with an integral Anti-blowback device c/w Ø200mm spigot for
connection to extract ductwork. It is recommended that the duct system flow rate is adjustable to
match the cabinet and can provide extraction at a volume/rate of at least 800m³/hr (1200) and
1300m³/hr (1800). It is recommended that a thimble connection is used within the duct to maintain
stable and balanced airflow.
Electrical connection and services
The cabinets are shipped with a 2m IEC lead terminated with a standard domestic plug (type
dependant on region). The lead plugs into the top, right hand side towards the rear. The IEC inlet
socket is protected by a fuse. This should only be replaced with a fuse of same type and rating.
Auxiliary switched connection
A volt-free switching contact facility is provided on the cabinet fitted with anti-blowback devices for
connection to external devices (eg. Duct fan). This changes state whenever the cabinet is operational
(fan running). Connection is via a supplied 3 pin plug and is wired as follows:

Testing and certification
The Cabinet should be fully tested and commissioned by suitably qualified persons before being put
into service. Safelab have a nationwide team of service engineers who can take care of your
installation, commissioning and service requirements. Please contact our service department for
further information.
