  • Page 12: About This Manual

    About This Manual This manual contains technical information for all types and models of Labconco biosafety cabinets and procedure stations. Type A2 biosafety cabinets with a 12 inch sash operating height, and C1 biosafety cabinets utilize two internal blowers, and Type A2 and B2 biosafety cabinets with sash operating heights of 8, 9, or 10 inch utilize one internal blower.

  • Page 13: Type B2

    Type B2 All Logic+ Type B2 biosafety Figure 1-2 cabinets meet the airflow requirements of ANSI/NSF Standard 49. All of the air in the cabinet is filtered and none is recirculated. All Type B2 Logic+ biosafety cabinets feature intrinsically safe designs, with all contaminated areas under negative pressure.

  • Page 14: Type C1 - B Mode

    Type C1 – B mode All Logic+ Type C1 biosafety Figure 1-4 cabinets meet the airflow requirements of ANSI/NSF Standard 49. The Chem-Zone (center work surface) air is filtered and exhausted via a remote building exhaust system, while the inflow and outer work surface air is filtered and recirculated.

  • Page 19: Safety Precautions For This Product

    If your application requires loading more than 150 lbs. (68 kg), contact Labconco’s Product Service Department at 800- 821-5525 or 816-333-8811 for assistance.
  • Page 20 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 816-333-8811 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.

  • Page 28: 7: Exhaust System Connections

    7: Exhaust System Connections Not all models of biosafety cabinets are connected to a remote or building exhaust system. Type A2 models may recirculate their exhaust back to the laboratory, or remove their exhaust air from the lab via a Ventus Canopy (also referred to as a Thimble Connection) connected to a remote (building) exhaust system.
  • Page 29 Figure 7-2 Avoid cabinet locations that require an elbow directly above the cabinet’s exhaust connection or an excessive number of elbows in the exhaust system. There should be a straight length 10 duct diameters long between the cabinet connection and any elbow, and between subsequent elbows.

  • Page 30: Air-Tight Damper

    Air-Tight Damper On canopy-exhausted Type A2 and C1 (operating in B-mode) models, Labconco highly recommends installing an air-tight damper above each biosafety cabinet when connected to a building exhaust system. The air-tight damper allows for fine adjustment of the exhaust air volume provided, in order to correctly set the necessary exhaust airflow for each biosafety cabinet.

  • Page 31: Exhaust System Requirements

    Exhaust System Requirements The exhaust system must be capable of moving the following volumes of exhaust air at the negative pressures listed. The Airflow Volumes are the values recorded via direct measurement using a flow hood at the front opening of the cabinet. The Concurrent Balance Values are measured in the exhaust duct via traverse methodology, and will always be higher due to differences in volume measurement methodologies.

  • Page 43: Adjusting The Internal Air Damper

    Adjusting the Internal Air Damper On Type A2 8-inch through 10-inch sash heights and all Type B2 (single blower) models, during the certification of the biosafety cabinet, it may be necessary to adjust the split of air between downflow and exhaust. This is an important part of balancing the biosafety cabinet and hitting the specified average downflow and inflow values specified for each model and size cabinet.
  • Page 44 2. Locate the exhaust damper adjustment bolt (reference Figure 9-2). The adjustment bolt is in the center of a flexible, orange cup seal. Use a 7/16-inch nut driver or socket and ratchet to turn the bolt. The bolt has 16 turns from fully open to fully closed.

  • Page 45: Setting The Filter Life Gauge

    Setting the Filter Life Gauge During initial or annual certification of the biosafety cabinet, and after the HEPA filters are changed, the Filter Life Gauge may need to be reset. There are three options to choose from when resetting the Filter Life Gauge. Below are the three options, and an explanation on which to select.

  • Page 47: Airflow Sensor Calibration

    Airflow Sensor Calibration All Type B2 biosafety cabinets have an airflow sensor to sense the exhaust air pulled from the cabinet by the remote (building) exhaust system. Type A2 and C1 biosafety cabinets may have an airflow sensor as an optional accessory. Unless installing or replacing the airflow sensor, the zero point should be correctly set from the factory (see Zero Point Calibration later in this section).

  • Page 48: Type B2

    3. Using the average downflow velocity measured during airflow certification, use [UP] [DOWN] to adjust the Nominal Downflow Value to match this measured velocity. The Nominal Downflow Value will flash, and it will be displayed in feet per minute (FPM) or meters per second (M/S) based on the desired units selected in the Settings submenu.
  • Page 49 3. The nominal set point for Inflow has been set in the previous step. Now the alarm set point must be established. The screen below is displayed. While on this screen, reduce the remote or building exhaust system until the TOTAL volume of air drawn by the remote exhaust system is reduced to 90% of nominal.

  • Page 50: Zero Point Calibration

    Zero Point Calibration If a new airflow sensor is being calibrated (field installation or replacement), a zero point calibration will be performed. To gain access to the Zero Point Calibration screens, a different password must be entered on the Password Screen.

  • Page 51: Vacuum Start Switch Calibration (Type C1 Only)

    Vacuum Start Switch Calibration (Type C1 only) A Type C1 biosafety cabinet operating in B-mode must sense sufficient remote exhaust volume before starting the internal blowers. This is accomplished with the Vacuum Start Switch (VSS) located in the exhaust housing of the biosafety cabinet. After setting the Filter Life Gauge, or calibrating the Airflow Sensor (if present), a Type C1 biosafety cabinet will ask if the VSS needs to be calibrated.
  • Page 52 1. After selecting on the screen to the left below and pressing [OK/MUTE], watch the Inlet Relief Valve and slowly reduce the remote exhaust system flow until the Inlet Relief Valve begins to flutter, but is not completely closed. Hold the remote exhaust system flow at this point.

  • Page 53: 10: Certification

    10: Certification This section provides instructions to certify the biosafety cabinet. Use this section in conjunction with Section 9: Calibration when performing initial or annual certification. Never enter the password-protected area, or change settings of the biosafety cabinet if you are not a trained and qualified certifier or technician. Changing parameters in the password-protected area may impair the product’s performance and result in loss of protection and/or harm or death to personnel in the laboratory.

  • Page 54: Theoretical Upstream Concentration

    If the biosafety cabinet has been used with biohazards, toxic chemicals, or radioisotopes, the Upstream Sample Tube cannot be used (Figure 10-1). Testing at Labconco has shown the actual concentration varies from the theoretical value. Table 10-1 shows the actual vs. calculated concentrations for Type A2 models. Establish the 100% and 0% concentration levels for the photometer using the actual values provided in Table 10-1 for the model being tested.

    5. Open the correct number of Laskin Nozzles on the aerosol generator (refer to Table 10-1). 6. Scan the downstream side of the supply HEPA filter by passing the sampling nozzle in slightly overlapping strokes over the entire surface of the filter. The sampling nozzle must be no more than 1 inch from the surface of the filter media.

The aerosol generator and photometer should be prepared at this point as described in the preparation steps listed in the previous section.

  • Page 59: Acceptance Criteria

    Note: When scanning the edges of the exhaust HEPA filter, photometer operation may become erratic due to the aspiration of room air into the exhaust air stream. This problem can be minimized or eliminated by placing the edge of a sheet of rigid plastic or metal just outside the edge of the HEPA filter when scanning the filter edges.
