1. Product overvie
1.1 Basic product information
1.1.1 BSC-1304 Ⅱ B2 Biological safety Cabinet (hereinafter referred to as the cabinet) has been
designed and manufactured conforming with the standard YY0569-2011 Class Ⅱ Biological
Safety Cabinets, A2 type.
1.1.2 The front access opening, through where the operator works in the cabinet. The room air flows
into the front access opening, forms an air barrier to prevent aerosols escaping from the
cabinet’s working area, so protects operator. ULPA-filtered air flows downward through the
working area, providing product and cross contamination protection. ULPA-filtered air exhausts
out of the cabinet, which protects the environment.
1.1.3 The cabinet may be the best physical protective barrier to protect personnel, product and the
environment. The operator must be well trained and familiar with the safety operation rules
before use the cabinet. Misuse will cause immediate harm to personnel, product and the
environment.
Reminder: Must be operated by trained personnel.
Warning: B2 type cabinet can be used for microbiological experiment hich uses
volatile toxic chemicals or radionuclide as adjuvant.
Reminder: Misuse ill cause immediate harm to personnel, product and the
environment.

from the front side to let
the cover fall off, then
install the water/gas pipes.
Diameter: 30mm

12
Reminder: Please avoid turbulent flo around the cabinet. Especially pay attention to
the directional flo generated from the air inlet, air outlet, or ventilation opening of the
room, hich may destroy the air barrier of the cabinet, and the operator and the product
might lose the protection.
Reminder: B2 cabinet must connect to external exhaust fan, and have its o n exhaust
system, the exhaust air volume should comply ith the exhaust emission requirements.
Reminder: the connection of exhaust pipeline and cabinet air outlet may use soft

8.7 Exhaust system installation
Reminder: B2 type cabinet exhausts 100% air to outdoors, no indoor air circulation.
（ 1 ） Exhaust system consists of sealing pipeline, regulating valve, and external exhaust fan.
（ 2 ） To compensate the pressure loss in the pipeline and the resistant of the ULPA filter(at least
500Pa), the static pressure of the exhaust fan is suggested to be more than 700Pa.
（ 3 ） An air flow measuring device is recommended to equipped to monitor the air volume in the
exhaust pipe line.
（ 4 ） The cabinet can only be started up when the exhaust fan or user building ventilation system is
working.
（ 5 ） The cabinet is with serious hazard, to keep the air flow balance, the exhaust air volume
should be kept constant.
（ 6 ） If exhaust directly to the atmosphere, please make the exhaust system according to the
appendix A.2.3 in industrial standard <YY0569->.
Reminder: the exhaust fan uses independent po er source. The control signal ill be
leaded out from

After installation and before use, related performance indexes of the cabinet should be validated.
Reminder: after validation and parameter regulation, please do not regulate the air valve
or exhaust valve any more.
Reminder: Exhaust air volume ill affect the air flo balance in the cabinet, and in the
end affect the performance.

14
Reminder: please arrange for qualified person to perform the validation.
Reminder: Do not use the cabinet hich is not validated.
8.8.2 Belo are the optional items for on-site validation:
① Visual inspection
② Function test (alarm, interlock, display &etc.)
③ ULPA filter integrity test
④ Downflow
⑤ Inflow
⑥ Air flow pattern
8.8.3 Reserved test ports
8.8.4 Re-validation requirement
Reminder: Re-validation is needed hen the cabinet has been used for one year, or just
replaced fan, or changed filters.
Warning: Except for first validation, disinfection is needed before re-validation.
Warning: Inform the person ho is performing the validation about the hazard of the
product in the cabinet, so they may ear necessary PPE.
