NOTES:
All power values measured at 10 inch operating sash height.
The powered base stand, if ordered, will take an additional 8.6 amps at 120 VAC; 60 Hz or 4.3 amps at 230 VAC;
50 Hz.
The electrical outlets inside the Interceptor® are grounded. This is particularly important since all internal surfaces
are stainless steel and conduct electricity. Under NO CIRCUMSTANCES use ungrounded plugs in these outlets.
It is not recommended to use in excess of 1500 watts of power. Exterior power plugs must not be removed until
unit fan and lights are turned off. The unit is to be disconnected from the main voltage by unplugging both plugs to
remove power. For electrically-powered base stands, power for disconnect is also accomplished by plug removal
from a waste-high or lower plug outlet.
The Interceptor® Cabinet has one power cord. If the Power Base is employed, a total of two power cords are
used. When positioning the BSC, always connect BSC and stand power plugs in waste-high or oor-positioned
outlets to facilitate disconnection in an emergency. Never block these outlets.
If UV option is on your BSC, be sure safety overrides are never immobilized! UV lamp should NEVER be on while
sash is open.

Tips
The following are recommended for control of ergonomic-related issues associated
with the use of Biological Safety Cabinets:
• Use an ergonomically designed chair that provides adequate back support,
adjustable seat angle, and height adjustability between 18 inches to 28 inches.
• Place anti-fatigue matting in areas for users who must stand for extended
periods of time.
• Place working materials in recommended order to create ‘ow’ “clean to dirty”.
• Take frequent mini-breaks to perform stretching.
• Proper posture should always be practiced. Use of footrest when working
seated is recommended.
• Upper shoulders and upper arms should be relaxed; ensure chair seat height
is aligned properly to provide no stress to upper shoulders or upper arms when
forearms are resting on tabletop (wrist should always align with forearm – think
straight, horizontal line).

Room Location
It is imperative that the Biological Safety Cabinet be placed in the correct location
within the room. Ideally the location of the cabinet will be away from any type of room
air turbulence and out of high trafc areas within the laboratory. Air turbulence can
be created by a number of things including; but not limited to, air ducts, doorways,
windows and foot trafc. Placing the cabinet in direct path of unstable air ows can
cause contamination of the cabinet workspace and/or allow contaminates to escape
from the cabinet into the room.
It is also important to keep the proper distance away from the ceiling when
exhausting back into the room. The minimal acceptable height is 3 inches (8cm) from
the ceiling. Less than 3 inches (8cm) clearance constricts the exhaust and reduces
the ow into the cabinet at the front access opening.
First and foremost always refer to your facilites Standard Operating Procedures
(SOP). Always use best housekeeping practices. Never store items on top of the
cabinet. Never remove the exhaust lter cover unless cabinet is being certied by a
technician. If you have questions about cabinet location, please contact Kewaunee
Scientic Corporation at www.kscmarketing@kewaunee.com or 704-873-7202.

Unpack and Inspection
When unpacking your new Interceptor® Biological Safety Cabinet, it is imperative
that a thorough inspection be performed to ensure that there is no freight damage.
If any damage is found at time of delivery, it should be noted with the carrier on
paperwork. If damage is concealed owner must contact the freight carrier within 15
days of delivery per the United States Interstate Commerce Commission rules and
regulations. Kewaunee Scientic Corporation and its dealers are not responsible for
damages occurring during shipment.
Assembly and Setup
The Biological Safety Cabinet should be maneuvered, as close as possible, to its nal
location with the assistance of either a furniture dolly or oor jack. Attempts to move
the unit by tilting it onto a hand truck greatly increases the risk or injury to the
handler and damage to the Biological Safety Cabinet.

Electrical Power Connection
The Interceptor® has one power cord which is packed in the Loose Parts box inside
the cabinet. The cord supplies power to the two internal outlets, the fan, alarm
control system, and lights. The female ends must be inserted into the corresponding
recepticles on the Electrical Junction Box at the top of the cabinet and twisted to
lock into place. The other end should be plugged into 120 VAC, 20 amp, grounded,
electric outlet. Always use waste-high or oor-positioned outlets to facilitate
disconnection in an emergency. The powered stand, if ordered, takes an additional
8.6 amps at 120 VAC or 4.3 amp 230 VAC, off its own power cord and should also be
plugged into a waste-high or oor-positioned outlet.
! WARNING
ê
The electrical outlets inside the Interceptor® are grounded. This is particularly
important since all internal surfaces are stainless steel and conduct electricity.
Under NO CIRCUMSTANCES use ungrounded plugs in these outlets.
As soon as the cord is connected, you are ready to follow the “Startup” procedure
on page 4.2. Electrical plugs must not be removed until cabinet fan and lights are
turned off. The cabinet should be disconnected from the main voltage by unplugging
to remove power. For electrically-powered lift stands, disconnection is also
accomplished by plug removal.

CHAPTER 4
Cabinet Operation
Theory of Operation
The Interceptor® is a Class II, A2 Biological Safety Cabinet. Its function is to
isolate bacterial samples from cross-contamination and protect the user and
the environment around the cabinet from being contaminated by biological or
particulate material inside the cabinet.
It accomplishes this objective by bathing biological samples in HEPA ltered clean
air while keeping contaminants contained by having a continuous substantial inow
of air through the 10” cabinet sash opening.
The BSC will safely operate at a temperature range of 55ºF to 85ºF (13ºC - 29ºC) and
a relative humidity of 10% to 70%.
Class II, A2 Biological Safety Cabinets are made to safely contain bacterial samples
that fall into the Biological Safety levels 1, 2, 3, and 4 if accompanied by level
appropriate protection garments. The following is a description of each level as
published in the CDC BMBL 5th edition:
“Biological Safety level 1 (BSL-1) is the basic level of protection and is
appropriate for agents that are not known to cause disease in normal,
healthy humans. Biological Safety level 2 (BSL-2) is appropriate for
handling moderate-risk agents that cause human disease of varying
severity by ingestion or through percutaneous or mucous membrane
exposure. Biological Safety level 3 (BSL-3) is appropriate for agents with
a known potential for aerosol transmission, for agents that may cause
serious and potentially lethal infections and that are indigenous or
exotic in origin. Exotic agents that pose a high individual risk of lifethreatening disease by infectious aerosols and for which no treatment
is available are restricted to high containment laboratories that meet
biosaftey level 4 (BSL-4) standards.”
! WARNING
ê
Class II A2 Biological Safety cabinets must be certified before initial use, after
being moved, and after any service, including required annual recertification.
Service must be performed by an NSF accredited certifier using NSF/ ANSI 49
criteria and should include, at minimum, the following test:
• Downflow Velocity Profile Test
• Inflow Velocity Test
• Airflow Smoke Pattern Test
• HEPA Filter Leak Test

Suggested or Recommended Workflow
Once skilled in your lab’s Standard Operating Procedure (SOP), don appropriate
protective garments and gear suitable to the level of safety required. Place items
for use in the procedure in the left section of the work area. Place equipment in
the center of the work area. Designate the right section of the BSC for waste to be
disposed of at the procedure’s end.
As you perform the procedure, waste materials will accumulate on the right side of
the cabinet.
After the procedure is nished, remove waste materials, disinfect as is customary at
your facility, and place materials away. Each time the unit is used, it should be left
clean. Follow your SOP for shut down or night setback procedures.
Night Setback/Low Flow Mode
The Interceptor® Biological Safety Cabinet is equipped with a two-speed motor to
save energy when it is not being used for active procedures. The cabinet is placed
into Night Setback/Low Flow Mode by closing the sash to a 1" opening. At 1", the
cabinet exhausts about 50% of the air the unit processes at a 10" opening. Do not
run active experiments at this 1" sash height.
When the sash is moved to a 1" opening, Night Setback/Flow Flow Mode, the Control
Monitor will look like Figure 4.11 below.
NOTE: Low ow is set to 50% of run speed. It is not
necessary to calibrate the BSC for this position.

Control Monitor
The Control Monitor Home/Face Velocity Screen can alert you to several possible
problems as you proceed:
1) High inow velocity (face velocity).
2) Low inow velocity (face velocity).
3) Sash Height Alarm – Always set the sash at the 10" line when conducting
experiments. This is the setting that has received NSF certication.
4) UV Light on and Fan on.
Figure 4.12 Home/Face Velocity Screen
Warning – Check Sash Height
UV Light
The UV germicidal disinfecting light may be used if one has been installed; fully
close the sash, and turn on the light using the UV Light button. Because UV rays
are dangerous, the light will not operate unless the sash is fully closed. Glass stops
UV radiation. If the UV light is not turned off before the sash is raised, the safety
interlock will disable the UV light.
! WARNING
ê
If the UV option is on your BSC, be sure safety overrides are never
immobilized! UV light should NEVER be on while sash is open.

Control Monitor Messages and Meanings
Variable Measurement Method Importantance Recommended Action
Airow
(optimal value
is 105 FPM)
Since the inow at any point of the
10" sash opening can vary widely,
it is the average inow (CFM/sq ft)
that is actually measured. Since
the “air in” through the 10" sash
opening exactly equals “air out”,
the exhaust port, the Interceptor
converts the FPM exhaust port
velocity into FPM inow velocity at
the sash opening.
Proper inow at 10"
assures containment of
contaminants within the
cabinet. NSF 49 requires
a minimum inow velocity
of 100 FPM.
®
The Home/Face Velocity
Screen shows airow. Any
velocity between 100 FPM
and 110 FPM is acceptable.
If face velocity falls below
100 FPM, discontinue work
and contact your Accredited
Technician for remediation.

The static pressure differential
between the negative and positive
pressure is proportional to lter
loading. It is measured by the
Pressure Sensor and converted by
the Contol Module to a lter loading

A micro switch interaction with
the counterweight activates this
warning.
When the sash is closed and the
fan is off, the disinfecting UV Light
may be activated using the UV Light
button on the Control Panel Touch
Pad.
The Interceptor® exceeds
NSF requirements for

The cabinet is designed
to be used at a 10"
sash opening. Any other
opening is inappropriate. If
the fan is on at any height
other than 10", the Yellow

Disinfection
It is recommended that your Biological Safety Cabinet be thoroughly disinfected
before and after each use. This procedure is to destroy any contaminates that may
remain within the cabinet and may compromise your work. This should be at least
part of your Standard Operating Procedure (SOP) but not a substitution for it. The
entire inside of the cabinet should be wiped down during the disinfection. This
includes the side and rear walls, the removable worksurface, both top and underside
(as needed) and the drain pan.
It is recommended that the cabinet fan be turned on before disinfection procedure
and allowed to operate for several minutes to remove any suspended particulates.
Cabinet interior should then be wiped down with 70% alcohol, or other approved
disinfectant. After cabinet has been thoroughly disinfected, then it is very important
to rinse the surfaces with sterile water to remove any residue.
Storage
If the Interceptor® is to be decommissioned or stored for protracted periods, consult
with your health and safety personnel for appropriate procedure.
If the lters were not full the last time the cabinet was used, all contamination will be
sealed inside the fan compartment and positive plenum, and therefore isolated.
The storage mode for the unit will be inuenced by at least the following issues:
1. Virulence or toxicity of materials used in the cabinet
2. Resistance of materials to UV light or other disinfection procedures used on the
cabinet interior
3. Length of time item is to be stored before reuse
Filters
Filter replacement must be completed by an NSF Accredited Technician. See
Maintenance and Technical Manual.

Operator and Product Protection
Safe Operation Guide
The Biological Safety Cabinet may only be used in the 10" sash open position due to
calibrated air ows. An opening other than 10" during a procedure will not protect
the operator from materials inside the hood.
Protective Clothing
The following are general guidelines only and should not replace any of your
laboratory’s Standard Operating Procedures (SOP).
Before beginning any work, the user should rst thoroughly wash their hands with a
germicidal soap.
Don appropriate personal protective equipment for the bio safety level and work being
performed. Operations being performed in BSL level 1 suggest wearing protective
laboratory coats, gowns or uniforms to prevent contamination of personal clothing.
Protective eyewear is also suggested.
BSL level 2 and 3 suggests wearing gloves, protective laboratory coats, gowns,
smocks or uniforms (possibly tie back, wrap around gowns or scrub suits). Eye and
face protection include goggles, mask, face shield or other splatter guard are also
suggested. Eye, face and Respiratory protection must be worn in rooms containing
infected animals.
All procedures being performed in a BSL Level 4 and using a class II BSC require the
user to wear a one piece air supplied positive protection suit.
UV Lamp
The Control Monitor Run Screen will alert the operator when the UV lamp should
be replaced. The lamp may still illuminate at this point; however, UV output will be
greatly diminished.

HEPA Filters
HEPA lters are the most important safeguard of a Biological Safety Cabinet. The
HEPA lter has a proven efciency of 99.99% at 0.3 microns. The HEPA lter is made
from a single sheet of borosilicate bers that have been treated with a wet-strength
water–repellant binder. The lter is pleated to increase overall surface inside the
lter frame and is protected by corrugated aluminum separators. These separators
protect the pleats from collapsing and provide a path for airow. Although aluminum
separators are most common, there are other materials that are acceptable. The
lters are then glued to a wood, metal or plastic frame. The lters are very fragile and
careless handling can easily compromise their integrity. It is important that the lters
be leak tested when initially installed and whenever the cabinet is moved or relocated.
Note that much of this information is credited to CDC BMBL 5th Edition.
HEPA lters are only efcient on particulates; they are not designed to lter gases.
It is important to check the lters on a regular basis (at least annually during
recertication). As the lters collect particulates, it will become increasingly harder
to maintain the airow balance within the cabinet. Filters should be changed at
recommended intervals to ensure proper airow is being maintained within the
cabinets.
