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+ HAS AN
OPTIONAL EN/CONTACT CIRCUIT BOARD THAT HAS DRY
CONTACTS THAT CAN BE CONFIGURED TO SIGNAL THE
EXHAUST BLOWER TO TURN ON WHEN THE LOGIC+’s 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 biosafety cabinet models have the following electrical requirements:

Model # Requirements

3x34xxx0x 115 VAC, 60 Hz, 12 Amps
3x34xxx1x 100 VAC, 50/60 Hz, 12 Amps
3x34xxx-20, 30, 40, 50, 60, 70 230 VAC, 50/60 Hz, 6 Amps

3x36xxx0x 115 VAC, 60 Hz, 12 Amps

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 40 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.

User-Supplied Microscope Requirements –
Purifier Cell Logic Biosafety Cabinets with
Scope-Ready™ Package Only

If installing a microscope, locate the Stand-Still™ Isolation Platform in a
separate box shipped with the cabinet. The Stand-Still Isolation Platform
supports the microscope on top of the stainless steel work surface to
eliminate up to 94% of vibrations and to promote safe airflow. If using a
stereoscope with a forward extending base, the extended Stand-Still XL
Isolation Platform should be ordered from Appendix D: Accessories. Figures
from Appendix F should be used to assist your set-up.

On models with the Scope-Ready package, the Cell Logic Biosafety Cabinet
includes a clear, disposable Pure-Vu™ Seal that can be altered to
accommodate most microscope’s eyepieces. Utilize the Punch Kit
(#4027801), supplied with your cabinet, to cut the two eyepiece holes at
approximately 2.75" (69.9 mm) spacing to match the height of your scope.
As a convenience, pre-cut Pure-Vu eyepiece seals can be ordered from
Appendix D: Accessories. The pre-cut accessory Pure-Vu Seals are based off
the nominal height from the base of the microscope to eyepiece centerline
and can save you valuable time modifying the seal shipped with the Cell
Logic. If using a stereoscope with a forward extending base, one of the Pure­Vu XL Seals should be ordered from Appendix D: Accessories. Figures from
Appendix F should be used to assist your set-up for all Pure-Vu Seals.

User Supplied Circulator Requirements – Purifier
Cell Logic Biosafety Cabinets with Temp Zone™
Package Only

The Temp Zone™ features a temperature controlled area on the work surface
where heated or chilled samples may be transferred and kept at optimum
temperature. A user-supplied circulator that continually delivers heated or
chilled water at a minimum flow rate of 0.5 GPM (1.9 LPM) with typical
volume of 6 liters is required and may be obtained from your laboratory
supply dealer. See Figure 3-6 in Chapter 3.

Quick connection fittings are included on the left side of the cabinet and are
sized for 3/8" diameter polyethylene tubing. As a convenience, an ample
supply (20'; 6 m) of 3/8" (9.5 mm) diameter tubing, insulation, and quick
connect fittings (3/8 tube x 1/8 NPT, 3/8 tube x 1/4 NPT, 3/8 tube x 3/8 NPT)

Connecting the Biosafety Cabinet to Utility
Service Lines

Note: Some models have a solenoid valve connected to the service valve on
the right side, rear position. The solenoid prevents gas from flowing to the
service valve when the unit blower is off. It is the only service valve position
that can be fitted with a solenoid valve. Connect the gas service to the
solenoid valve.

The service lines (if any) should be connected to the tube fitting(s) on the
outside of the liner wall as shown in Figure 3-1. 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.

Chapter 3: Getting Started

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 (19 mm) 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

shutoff valve on the service valve. Test all fittings for leakage. Tighten
the tube nut slightly if needed.

Optional Vacu-PassTM Cord & Cable Portal Use

Note: There must be enough clearance to pass the cord or cable between the
Logic+’s exterior dress panel and any obstruction.

Note: Some Vacu-Pass components and the cord or cable passing through it
may become contaminated during use of the cabinet. Ensure all potentially
contaminated components are surface decontaminated before handling or
removal from the cabinet.

1. Remove the grommet from the liner side wall. Remove the solid sealing

plug from the body of the portal by either pressing it through from the
outside, or by carefully inserting a spatula or similar device between the
sealing plug and the body of the portal, and prying the plug out.

2. Pass the cord or cable through the body of the portal, and then through

one of the plugs that has been cut for cord or cable use, then through the
grommet, as shown in Figure 3-2.

Note: select a plug with a hole that is slightly smaller than the cord or cable,
to create a proper seal. This will also help minimize movement of the cord or
cable if it is accidentally pulled during use.

Figure 3-2

3. Position the cord or cable as it will be used in the cabinet, and then push

the plug back into the body of the portal until it seats in the portal.

Circulator Installation (optional)

In order to successfully install a user-supplied circulator on a Cell Logic
Biosafety Cabinet with Temp-Zone package please follow the steps below
and refer to Figure 3-5:

Note: The work surface is heavy and two Easy-Clean™ Prop Rods are
provided to pivot and support the Temp-Zone work area and the work
surface.

1. The Temp-Zone work area has supply and return lines for the user-

supplied circulator. Refer to Figure 3-5 and locate the two quick
connect elbows on the left side of the cabinet behind the left side
panel.

2. Find a suitable place next to the cabinet or underneath the cabinet to

place the circulator. Accessory shelves for small circulators are
available from www.labconco.com. Larger circulators should be
placed on the floor.

3. Pivot the work surface up and use the Easy-Clean Prop Rods to

support the work surface. Then locate the tubing, insulation, and
quick connect fittings shipped with your Cell Logic. The tubing is
3/8" OD (9.5 mm) and tube inserts must be placed inside the tubing to
properly support the tubing inside the quick connect fitting. 20 feet
(6.1 meters) of tubing length is provided for your convenience.
Note: The tube inserts prevent the tubing from collapsing at
connection points and must be used.

4. Plan, route and cut the tubing from the two elbows on the left side of

the cabinet to the circulator.

5. Locate the quick connect fittings (3/8" tube x 1/8 NPT, 3/8" tube x 1/4

NPT, and 3/8" tube x 3/8 NPT) and install the appropriate fittings to the
user-supplied circulator with appropriate pipe sealant or PTFE tape.

6. Place tube inserts in all ends of the cut-to-size tubing.

7. Cut and install the insulation around the cut tubing lengths.

8. Insert cut tubing lengths into the elbows on the cabinet and then

install both tubing lengths into the circulator to complete the water
circulator loop.

9. Read and follow the circulator instructions before operating. The

circulator should have a minimum flow rate of 0.5 GPM (1.9 LPM).
In all cases, the temperature of the circulator will not equal the
temperature of samples on the Temp-Zone. Factors such as the
sample vessels, sample sizes, aluminum tube racks, and length of
tubing connecting the circulator to the Temp-Zone can influence the
sample temperature. Circulator settings to hold heated incubator
sample temperatures may require 0.3-2.0°C higher temperatures than
the desired sample temperature. Furthermore, circulator settings to
maintain chilled refrigerated samples may require 0.3-3.0°C colder
temperatures than the desired sample temperature. Experimentation is
necessary to achieve proper sample temperatures.

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

• Optional Canopy Alarm Test and Operation

• 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.

Chapter 4: Performance Features and Safety Precautions

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 typically held in place 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+ cabinets are at least 99.99%
efficient in removing particles 0.3 micron.

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+ 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.

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.

Chapter 4: Performance Features and 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

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.

Chapter 4: Performance Features and 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: Do not block or obstruct the grilles of the biosafety cabinet.

The internal ductwork of the biosafety cabinet conveys the air from the work
area to the blower, and then from the blower to the filters. The positive
pressure rigid plenum of the biosafety cabinet is designed to deliver a more
uniform airflow to both HEPA filters, optimizing filter loading and
operational life.

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 at this wavelength 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+ 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.

Product Service 1-800-522-7658

Original instructions

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 Health and Safety Officer at your
facility for UV light use and recommendations.

Scope-Ready™ Package Option

Models with the Scope-Ready package option allow a user-supplied
microscope to be integrated into the safety cabinet. On these models, two
features work together to assure containment and reduced vibration:

• The Pure-Vu™ Seal includes a 7" wide x 10.5" (267 mm) high sash

• The Stand-Still™ Isolation Platform supports the microscope on the

Temp-Zone™ Package Option

Models with the Temp-Zone package option include a temperature controlled
area 10.5" (267 mm) wide x 12" (305 mm) deep (7" (178 mm) wide x 12"
(305 mm) deep on 3' models). Samples heated in an incubator or chilled in a
refrigerator may be transferred to the Temp-Zone and kept at optimum
temperature. Quick connection fittings on the left side of the cabinet attach
to a user-supplied circulator that continually delivers heated or chilled water
through channels located underneath the Temp-Zone area of the work surace.
Uniform temperature distribution is maintained on the Temp-Zone area of the
work surface. Temp-Zone work area temperatures of 0.3-0.5°C are
maintained with the circulator heated to 37°C and within 0.3-1.6°C with the
circulator chilled to 3.7°C. Actual set points will vary depending on
variables such as sample tube rack, sample size, and length of tubing.

Safety Precautions

Note: 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. Filter integrity and airflow
performance should be verified before using the cabinet.

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 work surface 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.

Original instructions

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.

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.

Chapter 4: Performance Features and Safety Precautions

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.

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.

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 either an 8- or 10-inch (203-254 mm) sash opening, depending on
model. 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 OK/Mute
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.

Chapter 5: Using The Cabinet

the pleated Pure-Vu XL Seal. Figures F-11 and F-12 show typical complete
installations of stereo microscopes and proper placement of the Stand-Still
XL Isolation Platform. Listed next are instructions for setting up the pleated
design of the Pure-Vu XL Seal.

1. Per Figure F-3, with the outer aerodynamic collar removed, place the

Pure-Vu XL Seal over the inner aerodynamic mounting collar.
Locate the top five holes and secure with transparent tape as shown.
Pure-Vu XL Seals allow for eyepiece height flexibility of +/- 2.0" (51
mm).

2. Per Figure F-4, form the first pleat and secure with transparent tape.

The seal shown has pre-cut eyepiece holes (Labconco #4027811) and
is designed for the upper portion of the glass cutout. This upper
portion of the glass cutout is used frequently with stereoscopes.
However, should you need a pleat at the middle or lower position of
the glass cutout, then the pleat can be moved lower when setting up
the Blank Pure-Vu XL Seal (4027810). See Figure F-4.
