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 cabi net’s exhaust system requirements, please go to Section 3: Getting Started.

A dedicated outlet with an appropriate circuit breaker 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. Consult your local electrical codes for properly rated circuit breakers. For safe operation the dedicated outlet must provide the protective earthing ground connection to the cabinet.

On 100 and 115 VAC models, both internal electrical outlets are protected by a ground fault interrupter circuit (GFIC). Labconco does not recommend plugging the cabinet into a GFIC outlet.

Electrical outlets in the cabinet are restricted to 5 amps (115 Volt models) or 2 amps (230 Volt models) maximum current.

Les prises électriques dans l'armoire sont limitées à 5 ampères

(modèles 115 volts) ou 2 ampères (modèles 230 volts) courant maximum.

Do not use any detachable power cord that is not adequately rated for the unit.

Ne pas utliser un fil électrique amovible qui n’est pas du tension nominale de l’appareil.

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.

The use of flammable gases or solvents should be avoided in the 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.

Exhaust System Connections

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

WARNING: The Logic Total Exhaust Biosafety Cabinet is designed to be connected to an appropriate exhaust system. Without verified inflow velocity, the cabinet may NOT contain hazardous particulate or gasses. Do not attempt to operate it when it is not connected to an appropriate exhaust system that has been inspected by a qualified certifier.

WARNING: Type B2 Biosafety Cabinets rely on external blowers

(usually on the roof of a building) to exhaust 100% of the air entering the cabinet. If the building exhaust blower fails or is mistakenly turned OFF, the cabinet will become pressurized, resulting in a flow from the work area into the laboratory. It is imperative that the following be considered in a risk assessment:



Justify the type of work is appropriate for the cabinet Type B2.



Exhaust system must be reliable, maintained, frequently inspected and preferably redundant.



Exhaust termination must be distant from other building air intake systems to prevent the reintrainment of volatile chemicals.

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.

17


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.

Exhaust System Requirements

The cabinet exhaust stack is sized to accept 10-inch (254 mm) stainless steel ductwork. The exhaust sys tem’s blower should be sized to handle the exhaust volume of each cabinet, as shown in the QuickChart (Appendix E). The exhaust system must maintain a static pressure equal to or greater than the system pressure, plus a pressure of 1.5 inches (38 mm) 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

(Catalog Number 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. SEE APPENDIX D.

Connecting the 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, or there is a loss of electrical power. 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.

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. Make sure the tube ferrule is in the fitting.

18


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 cabinet and then slowly open the shutoff valve on the service valve. Test all fittings for leakage. Tighten the tube nut slightly if needed.

Using the Optional Vacu-Pass

TM

Cord & Cable Portal

There must be enough clearance to pass the cord or cable between the cabinet

’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 sidewall. 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. Locate the pass-thru universal sealing plug, which is included in the parts box located underneath the work surface during shipment.

3. Pass the cord or cable through the body of the portal, and then through one of the holes in the pass-thru universal sealing plug, then through the grommet, as shown in Figure 3-2.

Note: select a hole in the sealing plug 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

4. 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. Reinstall the grommet.

20


Installing the Drain Valve

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. Locate the Drain Valve components and installation hardware. The components and hardware are shipped in a single bag inside the parts box, underneath the work surface.

2. Lift the work surface out of the 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.

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

4. 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 3-3. Wipe off any excess sealant from the cabinet bottom. Ensure that the center drain hole is unobstructed.

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

6. Reinstall the work surface.

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

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 cabinet liner.

Figure 3-3

21


Initial Certification

Prior to use, a qualified certifier should certify all cabinets. Under normal operating conditions, the cabinet should be recertified at least annually and when relocated or serviced. The certifier should perform the following tests, as recommended in

NSF/ANSI 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 help locating one, contact Labconco’s Product Service Department at (800) 821-5525 or +1 816-333-

8811.

4: Performance Features and Safety

Precautions

All 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 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 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 cabinet are at least 99.99% efficient in removing particles 0.3 micron.

23

4: Performance Features and 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.

Figure 4-1

(A continuous sheet of filter media)

ULPA Filters

Optional ULPA filters may be used to replace the standard HEPA filters in the cabinet. 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.

24


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 shown in Figure

4-2.

Figure 4-2

25


Directional Airflow

Directional airflow also plays a key role in 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

26


Motor/Blower

The motor/blower assembly pulls room air into the front of the cabinet, and recirculates it internally. During its recirculation, the air is split into two separate streams. One path leads through the exhaust HEPA filter and out of the unit. The second path flows through the supply HEPA filter, which then flows down through the work area, as shown in Figure 4-4. The motor in the 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 utilizes Labconco’s exclusive Constant Airflow Profile TM (CAP) program to deliver a consistent volume of air, throughout the life of the cabinet.

Figure 4-4

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 (FPM) or meters per second (M/S).

27


Cabinet 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 cabinet.

The internal ductwork of the 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 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 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 Health and Safety Officer at your facility for UV light use and recommendations.

28


Safety Precautions

Note: The 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 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 +1 (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 +1

(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 cabinet from electrical service.

Avoid the use of flammable gases or solvents in the 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 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 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 +1 (816) 333-8811 for recertification information.

The HEPA filters in the 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.

29


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 cabinet:



Avoid splashing the disinfecting solution on skin or clothing



Ensure adequate ventilation



Carefully follow the disin fectant’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 cabinet for a long period of time. Free chlorine will corrode stainless steel after extended contact

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
