Exhaust Requirements

NOTE: THE EXHAUST BLOWER CANNOT RUN AT ITS NOMINAL
FLOW RATE WITH THE SASH COMPLETELY CLOSED. IF YOU
CHOOSE TO CLOSE THE SASH COMPLETELY TO USE THE UV
LIGHT FOR SURFACE DISINFECTION, THEN THE EXHAUST
BLOWER MUST BE SHUT OFF, OR ITS FLOW RATE REDUCED 90%
OR MORE FOR PROPER OPERATION. THE LOGIC CONTROL BOARD
HAS DRY CONTACTS THAT CAN BE CONFIGURED TO SIGNAL THE
EXHAUST BLOWER TO TURN ON WHEN THE LOGIC BLOWER IS
ON. FOR FURTHER INFORMATION, CONTACT LABCONCO’S
PRODUCT SERVICE DEPARTMENT. AS AN ALTERNATIVE, A
REMOTE ELECTRICAL SWITCH FOR THE EXHAUST BLOWER CAN
BE INSTALLED NEAR THE LOGIC.

Before deciding on a location, examine it carefully to ensure that it
accommodates the cabinet’s exhaust duct. The area directly above the
cabinet’s exhaust port should be clear of structural elements, water and utility
lines, or other fixed obstructions. There should be enough clearance to allow
for the passage of a 10" stainless steel duct. Avoid cabinet locations that
require either an elbow directly on top of the cabinet’s exhaust connection or
an excessive number of elbows to clear other items. For a further discussion
of the cabinet’s exhaust system requirements, please go to Chapter 3: Getting
Started.

Electrical Requirements

The different Biosafety Cabinet models have the following electrical
requirements:

Model # Requirements

3441000-3441009 115 VAC, 60 Hz, 12 Amps
3441020-3441029 230 VAC, 50/60 Hz, 6 Amps

3461000-3461009 115 VAC, 60 Hz, 12 Amps
3461020-3461029 230 VAC, 50/60 Hz, 6 Amps

Note: A dedicated outlet with a circuit breaker rated at 20 amps should
be located as close as possible to the right rear side of the cabinet, at a
height even with, or higher than, the top of the bench or stand.

Note: On 115 VAC models, both electrical outlets are protected by a ground

fault interrupter circuit (GFIC). Labconco does not recommend plugging the
Biosafety Cabinet into a GFIC outlet.

Chapter 2: Prerequisites

Service Line Requirements

All utility service lines should be ¼ inch O.D., brass, copper, or stainless
steel, and equipped with an easily accessible shut-off valve. If the service
line pressure exceeds 100 PSI, it must be equipped with a pressure regulator
to reduce the line pressure.

Note: The use of flammable gases or solvents should be avoided in the
Biosafety Cabinet. Open flame in the cabinet will disrupt the laminar airflow
in the cabinet and may damage the HEPA filters. Flammable gases or
solvents may reach explosive concentrations in the cabinet or ductwork. If
you feel that the procedure requires the use of an open flame or flammable
materials, contact the institution’s safety office.

The use of air or gases under high pressure should be avoided as they may
seriously disrupt the airflow patterns in the cabinet.

Preparing the Biosafety Cabinet for Operation

Installation instructions for the cabinet (Labconco P/N 1056801) are attached
to the sash of the Biosafety Cabinet. If these instructions are missing or
unclear, contact Product Service at 800-821-5525 or 816-333-8811.

Installing the Biosafety Cabinet on an Existing
Work Surface

Note: The Biosafety Cabinet is very top heavy. Use caution when lifting or
moving it.

When installing the Biosafety Cabinet onto an existing work surface or
benchtop, ensure that the structure can safely support the combined weight of
the cabinet and any related equipment. The work surface should be at least as
wide as the Cabinet and 31 inches (787 mm) deep to properly support the unit.

A hole or notch may be cut in the supporting surface in the right front corner
to accommodate the optional drain valve.

Installing the Cabinet on a Labconco Base Stand

Labconco offers accessory Base Stands in a variety of configurations to suit
the particular needs. Please note that B2 cabinets are connected to exhaust
duct and are generally not placed on mobile stands.

Telescoping Base Stands

Adjust the leg height before installing the cabinet on top of the stand. The
height can be set in 1-inch intervals between 27.5 to 34.5 inches (699 to
876 mm), providing a cabinet work surface height from 30.0 to 37.0 inches
(762 to 940 mm). The Base Stands for each width cabinet are listed in Table
3-1 below.

Connecting the Biosafety Cabinet to Utility
Service Lines

The service lines (if any) should be connected to the tube fitting(s) on the
outside of the liner wall as shown in Figure 3-3. To install the tubing, follow
these steps:

1. Ensure that the tubing is ¼ inch O.D., soft metal, and that the end has
been completely deburred.

2. Route the tubing from the rear of the cabinet, ensuring that it will line up
with the slot in the back of the side panel. The slot is located from 8 ¾ to
11 ¼ inches (222 to 288 mm) from the bottom of the cabinet.

Note: Make sure that the tube routing will not contact any electrical wires.
DO NOT loop service line tubing within the side panels of the Cabinet.

3. Make sure that the nut on the tube fitting is loose, but do not remove it.
Look inside the fitting to make sure the tube ferrule is there.

4. Push the tube into the fitting until it is properly seated. The tube will go
approximately ¾ inch (19mm) into the fitting.

5. Tighten the tube fitting nut hand tight and then, using a 7/16-inch wrench,
tighten it at least ¾ turn more.

6. Close the service valve in the Biosafety Cabinet and then slowly open the

Exhaust System Connections

The Purifier Logic Series Total Exhaust Biosafety Cabinets are a “Type B2
cabinet,” meaning they direct their HEPA filtered exhaust air out of the
laboratory.

Note: The Logic Total Exhaust Biosafety Cabinet is designed to be
connected to an appropriate exhaust system. Do not attempt to operate
it when it is not connected to an appropriate exhaust system.

NOTE: THE EXHAUST BLOWER CANNOT RUN AT ITS NOMINAL
FLOW RATE WITH THE SASH COMPLETELY CLOSED. IF YOU
CHOOSE TO CLOSE THE SASH COMPLETELY TO USE THE UV
LIGHT FOR SURFACE DISINFECTION, THEN THE EXHAUST
BLOWER MUST BE SHUT OFF, OR ITS FLOW RATE REDUCED 90%
OR MORE FOR PROPER OPERATION. THE LOGIC CONTROL BOARD
HAS DRY CONTACTS THAT CAN BE CONFIGURED TO SIGNAL THE
EXHAUST BLOWER TO TURN ON WHEN THE LOGIC BLOWER IS
ON. FOR FURTHER INFORMATION, CONTACT LABCONCO’S
PRODUCT SERVICE DEPARTMENT. AS AN ALTERNATIVE, A
REMOTE ELECTRICAL SWITCH FOR THE EXHAUST BLOWER CAN
BE INSTALLED NEAR THE LOGIC.

THE EXHAUST CONNECTION IS A SEALED EXHAUST SYSTEM
FROM THE TOP OF THE CABINET TO THE REMOTE BLOWER. THE
EXHAUST SYSTEMS SHOULD BE DEDICATED TO A SINGLE
CABINET. THE CABINET IS EQUIPPED WITH AN EXHAUST FLOW
ALARM, SUCH THAT AN ALARM SOUNDS, AND THE CABINET
BLOWER SHUTS OFF IN THE EVENT OF INSUFFICIENT EXHAUST
FLOW.

If your research involves the use of toxic compounds or volatile materials,
contact your facility’s safety officer or Labconco to ensure that your Purifier
and its exhaust system are compatible with the materials you will be working
with.

Chapter 3: Getting Started

Exhaust System Requirements

The cabinet exhaust stack is sized to accept 10-inch (254 mm) stainless steel
ductwork. The exhaust system’s blower should be sized to handle the
exhaust volume of each cabinet, as shown in the QuickCharts, Appendix E.
The exhaust system must maintain a static pressure equal to or greater than
the system pressure, plus 1.5 inches (38 mm) of water for the Logic cabinet.
In order to get the maximum life out of the cabinet’s exhaust filter, the
system needs to be able to operate at an additional 2.0 inches (51 mm) of
vacuum, compared to the initial total system pressure.

NOTE: The exhaust system should be fitted with a backdraft damper
(Part #3858800) to prevent the reversing of airflow in the system.

LABCONCO MANUFACTURES EXHAUST BLOWERS AND A
BACKDRAFT DAMPER, WHICH ARE SUITABLE FOR MOST SINGLE
CABINET INSTALLATIONS. THE REMOTE BLOWER IS DISCUSSED
FURTHER IN APPENDIX D.

Drain Valve Installation

In order to prevent damage during shipping, the drain valve assembly has not
been installed. If desired, the valve should be installed after the Cabinet is in
its final location.

To install the valve assembly, follow these steps:

Note: The work surface is heavy. Use caution when handling it.

1. Lift the work surface out of the Biosafety Cabinet by lifting on the knobs
at the front of the work surface. Steady the work surface while pulling it
straight out the front of the cabinet.

2. Using a putty knife, remove and discard the stainless steel cover that is
sealed over the drain mounting holes. Scrape out remaining sealant that
is around the holes.

3. Apply a light coating of silicone sealant (user supplied) to the mounting
surface of the drain assembly. Attach the drain assembly under the
bottom of the cabinet as shown in Figure 3-4. Wipe off any excess sealant
from the cabinet bottom. Ensure that the center drain hole is
unobstructed.

4. Make sure the drain valve is in the closed position.

5. Reinstall the work surface.

6. Allow the silicone sealant to cure for at least eight hours before exposing
it to liquid.

Product Service 1-800-522-7658

NOTE: The drain valve assembly attaches to
the underside of the cabinet bottom.

Apply a light coat of silicone sealant to this
surface of the connector, aligning the three
holes in the connector with the three holes in
the Biosafety Cabinet liner.

Figure 3-4

Initial Certification

Prior to use, a qualified certifier should certify all Biosafety Cabinets. Under
normal operating conditions, the Biosafety Cabinet should be recertified at
least annually and when relocated or serviced. The certifier should perform
the following tests, as recommended in ANSI/NSF International Standard
Number 49 in effect when the cabinet was manufactured:

• Downflow Velocity Profile Test

• Inflow Velocity Test

• Airflow Smoke Patterns

• HEPA Filter Leak Test

• Vibration Test *

• Noise Level Test *

• Lighting Intensity Test *

*These tests are user comfort related tests and may be omitted at the

user’s or certifier’s discretion.

If you have any questions regarding certification agencies or need assistance
in locating one, contact Labconco’s Product Service Department at 1-800­522-7658 or 816-333-8811.

All Purifier Series Logic Biosafety Cabinets operate using the following
principles:

• Filtration and retention of particulates by High Efficiency Particulate

Air (HEPA) filter(s)

• Laminar airflow

• Directional airflow

The major components in a Biosafety Cabinet are:

• The HEPA filter(s) or optional ULPA filters

• The motor/blower to force air through the Cabinet

• Cabinet air intakes (grilles), ductwork and air balance controls

HEPA Filters

HEPA filters are disposable, dry-type particulate filters. The filter material or
media is typically made of borosilicate microfibers formed into a thin sheet,
in a process similar to the production of paper. This sheet is folded, or pleated
to increase its surface area. The pleats are held in place by aluminum
diffusers or by beads of glue that add rigidity to the media pack. The pack is
then set into a frame, and sealed as shown in Figure 4-1.

The HEPA filter manufacturer establishes the efficiency of the filter by
challenging it with an aerosol of known particle size. The number of particles
that penetrate the filter are quantified, and this establishes the efficiency of
the filter. Thus, the filters used in the Logic Series Cabinets are at least

99.99% efficient in removing particles 0.3 micron.

14

Product Service 1-800-522-7658

Chapter 4: Performance Features & Safety Precautions

Note: The HEPA filter media is very fragile. DO NOT touch the media. If
you think the media of a HEPA filter is damaged, DO NOT USE THE
CABINET. Have the HEPA filter integrity tested by a certifier before using
the cabinet.

Note: HEPA Filters are only effective against particulate material. Gases
will pass through the filter.

ULPA Filters

Optional ULPA filters may be used to replace the standard HEPA filters in
the Purifier Logic Series Biosafety Cabinets. ULPA filters have the same
properties as described above except they are rated at least 99.999% efficient
in removing particles 0.1-0.2 or 0.2-0.3 micron.

Chapter 4: Performance Features & Safety Precautions

Laminar Airflow

Laminar airflow is defined as the movement of a body of air in a single
direction, with a uniform velocity. In practice, the laminar downflow of air in
the cabinet captures any aerosol generated in the work area of the cabinet,
and directs it to the HEPA filters. In order to be true laminar downflow, a
number of individual downflow velocity test points (The Downflow Velocity
Profile) must be +/- 16 feet per minute (0.08 m/s) of the average of all the test
points. This is illustrated in Figure 4-2.

Figure 4-2

16

Product Service 1-800-522-7658

Chapter 4: Performance Features & Safety Precautions

Directional Airflow

Directional airflow also plays a key role in biosafety cabinet performance.
Air is drawn into the front of the cabinet at the front grille. This “curtain” of
air makes it more difficult for aerosols to escape out of the work area of the
cabinet and into the outside environment. This airflow is often calculated and
referred to as the Inflow Volume or Average Inflow Velocity. This is
illustrated in Figure 4-3.

Figure 4-3

Product Service 1-800-522-7658

17

Chapter 4: Performance Features & Safety Precautions

Motor/Blower

The motor/blower assembly pulls air through the top of the cabinet, and is
sent through the supply HEPA filter. The filtered air flows down through the
work area where it provides a clean environment to perform work. Room air
is drawn into the front intake grille. All of the air is then drawn through an
exhaust HEPA filter and out of the laboratory, as shown in Figure 4-4. The
motor in the Purifier Logic Series Cabinet is an electronically commutated
motor (ECM). The ECM is a brushless DC motor that includes its own power
supply to convert the incoming alternating current to direct current, as well as
its own microprocessor to control and measure the motor’s operation. The
motor is preprogrammed to deliver a consistent volume of air, even as the
supply HEPA filter loads over time.

Figure 4-4

18

Product Service 1-800-522-7658

Chapter 4: Performance Features & Safety Precautions

Airflow Sensor

An airflow sensor, located above the Exhaust HEPA filter, constantly
monitors the flow of exhaust air out of the cabinet. If the exhaust falls below
a safe level, the control board turns off the cabinet blower, and sounds an
audible and visual alarm. This prevents the escape of hazardous material
from the front of the cabinet, in the event of an exhaust system failure. The
airflow sensor reading is shown on the display as Inflow in feet per minute
(or m/s).

Cabinet Air Intakes (Grilles), Ductwork and Air
Balance Controls

The location, size, and pattern of the grilles at the front and rear of the work
area affect cabinet containment and performance.

Note: Never block or obstruct the grilles of the Biosafety Cabinet.

Ultraviolet (UV) Lamp

The optional UV lamp generates a primary wavelength of light of 254nm. A
secondary emission is in the visible (blue) wavelength, resulting in the
characteristic blue color while operating. UV light with a wavelength of 254
nm is biocidal, primarily by creating thymine dimers in DNA. These dimers
prevent the correct transcription of the DNA into RNA, resulting in cellular
death or viral inactivation. In order to be effective, the UV light must directly
strike the nucleic acid, and its effectiveness can be diminished or negated by
dissolved proteins or metals, or by other UV-opaque substances protecting
the target nucleic acid.

Because of its limitations, UV light should be used as an adjunct to good
surface disinfection practices. In order to get optimum performance from the
UV light, it should be replaced after 6,000 hours of operation or less, and the
exterior surface of the lamp should be kept clean and free of dust.

Note: The Logic Cabinet records the number of hours of operation of the UV
light. You can program in the number of hours (in 100-hour increments) it
will operate before a replacement message is displayed.

Note: UV irradiation is absorbed by the tempered safety glass of the sash.
Independent research has shown that the level of UV irradiation on the
outside of the cabinet’s sash is equal to background radiation levels.

Note: The UV sensitivity of a target organism varies, depending on the UV
output of the lamp, the genus and species of the organism, the medium the
agent is suspended in, etc. Contact the facilities Health and Safety Officer at

Chapter 4: Performance Features & Safety Precautions

Safety Precautions

WARNING: The Biosafety Cabinet should be certified by a certification
technician before its initial use. The cabinet should be recertified whenever it
is relocated, serviced or at least annually thereafter. Do not assume that filter
integrity and airflow performance have not been compromised during
shipping.

Some internal components of the Biosafety Cabinet may become
contaminated during operation of the unit. Only experienced personnel
competent in decontamination procedures should decontaminate the cabinet
before servicing these components. If you have any questions regarding
certification agencies, or need assistance in locating one, contact Labconco’s
Product Service Department at 800-821-5525 or 816-333-8811.

DO NOT load more than 50 lbs. (23 Kg) in the work area. Exceeding this
limit may damage the worksurface and its supports. Excessive weight in the
cabinet may increase the risk of it overturning, or failure of hydraulic lift
stands, resulting in the cabinet and stand overturning. If your application
requires loading more than 50 lbs., contact Labconco’s Product Service
Department at 800-821-5525 or 816-333-8811 for assistance.

Ensure that the Cabinet is connected to electrical service in accordance with
local and national electrical codes. Failure to do so may create a fire or
electrical hazard. Do not remove or service any electrical components
without first disconnecting the Biosafety Cabinet from electrical service.

Avoid the use of flammable gases or solvents in the Biosafety Cabinet. Care
must be taken to ensure against the concentration of flammable or explosive
gases or vapors. An open flame should NOT be used in the Biosafety
Cabinet. Open flames will disrupt airflow patterns, burn the HEPA filter
and/or damage the filter’s adhesive. Gases under high pressure should not be
used in the Biosafety Cabinet, as they may disrupt its airflow patterns.

HEPA filters only remove particulate matter. Operations generating volatile
toxic chemicals or radionuclides must be evaluated carefully.

The media of HEPA filters is fragile and should not be touched. Avoid
puncturing either HEPA filter during installation or normal operation. If you
suspect that a HEPA filter has been damaged, DO NOT use the cabinet;
contact a local certification agency or Labconco at 800-821-5525 or 816-333­8811 for re-certification information.

The HEPA filters in the Biosafety Cabinet will gradually accumulate airborne
particulate matter from the room and from work performed in the cabinet.
The rate of accumulation will depend upon the cleanliness of the room air,
operating time and the nature of work being done in the cabinet. The Filter
Gauge accurately displays the amount of filter life remaining.

Product Service 1-800-522-7658

Chapter 4: Performance Features & Safety Precautions

Proper operation of the cabinet depends largely upon its location and the
operator’s work habits. Consult the Installation and Normal Operation
sections of this manual for further details.

Avoid direct exposure of plastic or coated materials to ultraviolet (UV)
radiation. Never bypass the UV safety interlock that only allows the UV
light to work when the sash is closed.

When surface disinfecting the Biosafety Cabinet:

• Avoid splashing the disinfecting solution on skin or clothing.

• Ensure adequate ventilation.

• Carefully follow the disinfectant’s safety instructions.

• Always dispose of disinfecting solutions in accordance with local and

national laws.

• DO NOT allow disinfectants with high concentrations of free chlorine
to contact the stainless steel components of the Biosafety Cabinet for
a long period of time. Free chlorine will corrode stainless steel after
extended contact.

The electrical receptacle cover may be removed to facilitate surface
decontamination. In the event of gross contamination, the cover should
be removed, sterilized and/or decontaminated as required.

Biosafety Cabinets should be decontaminated for any of the following
reasons:

• Before maintenance work requiring entry into contaminated areas.

• Before HEPA filter changes.

• Before performing certification tests requiring entry into

contaminated areas.

• Before relocating the cabinet.

• Before changing research programs.

• After the gross spill of biohazardous material or toxic chemicals.

Figure 5-2

Status Area

The Status Area displays the system’s condition during operation, as well as
the inflow velocity. This line can display any of the following messages:

Blower Off

The cabinet blower is shut off.

Please Wait

For three minutes after the cabinet blower is turned on, the display will
say this, to allow the cabinet to reach proper operating conditions.

OK

The motor is operating properly, and the sash is not open too far.

Sash is too high

The sash is open too far for safe operation.

Airflow Alert

The airflow patterns in the cabinet have changed, resulting in a sudden
change in the motor speed. This is most likely due to a blockage of the
prefilter.

Chapter 5: Using The Cabinet

Exhaust Error

If the volume of exhaust air leaving the cabinet falls below a safe level,
this message is displayed, the cabinet blower turns off, and an audible
alarm sounds. Pressing the “Blower” button will restart the blower. If
there is still insufficient airflow, the alarm will sound again. IF THE
CABINET KEEPS GOING INTO EXHAUST ERROR, DO NOT USE
THE CABINET UNTIL THE PROBLEM HAS BEEN CORRECTED.

System Error

The motor and display circuit board are not communicating properly.
DO NOT USE THE CABINET UNTIL THE PROBLEM HAS BEEN
CORRECTED.

Data Area

The Data Area displays the Filter Gauge. This bar graph displays the percent
of remaining supply filter life. When the cabinet is new, or after the supply
HEPA filter is replaced, the gauge will be “full”, or display approximately
100%. As the filter loads, or if the prefilter is blocked, the bar graph will
show a reduced filter life.

The graph is user-selectable as a bar graph with percentage displayed, a bar
graph only, or a semi-circular graph showing filter life remaining.

Various factors such as temporary obstructions to airflow, temperature and
barometric pressure can cause the displayed percentage to vary slightly.
Ignore short term changes in the Filer Gauge’s value. As the Filter Gauge
approaches 20% remaining capacity, consider having the cabinet filter
replaced.

The inflow velocity is also displayed during operation.

Icon Area

The Icon Area displays icons for those features selected or in operation. The
Icons are:

Normal blower operation –

In this mode the cabinet blower is operating normally.

Fluorescent light

In this mode the fluorescent lights are operating. When the sash is
fully closed, the fluorescent lights automatically turn off.

Product Service 1-800-522-7658

Chapter 5: Using The Cabinet

UV light

In this mode the UV (germicidal) light is operating. When the
sash is fully closed, the UV light can be programmed to
automatically turn on. When the sash is raised, the light
automatically turns off, to protect the laboratory from UV
irradiation.

Timer

When either the interval or stopwatch timer mode is active, this
icon appears.

Security Lock

When the security lock is activated the keypad does not respond to
any buttons until the proper sequence of keystrokes is entered.

Mute

When this icon is on, the audible alarm is muted for

approximately 5 minutes.

Operating the Sliding Sash

The counterbalanced, anti-racking sash mechanism requires only a few
pounds of force to move the sash up or down. You can open or close the sash
smoothly with one or two hands positioned on either handle.

The sash position alarm and safety interlock system senses the sash position
and acts appropriately. The Biosafety Cabinet has been programmed to
operate at an 8-inch (203 mm) sash opening. Raising the sash above its
operating height will activate the audible and visual alarms. The audible
alarm can be temporarily muted (for approximately five minutes) by
depressing and releasing the Mute/OK button. Closing the sash back to its
operating position will reset the alarm and defeat the muting of the alarm.
The safety interlock system senses when the sash is closed and allows the
optional ultraviolet (UV) lamp to operate only when the sash is closed, to
protect the operator from irradiation.
