3. Product Overview

The Labconco Purifier Logic Class II, Type A2 Biological Safety Cabinet provides a controlled environment for handling hazardous biological materials. It operates by maintaining a continuous inward airflow at the work opening, a downward HEPA-filtered laminar airflow within the work zone, and HEPA-filtered exhaust air.

Key features include:

• Class II, Type A2 Classification: Provides personnel, product, and environmental protection.
• UV Light: Integrated for decontamination purposes.
• Service Fixture: For utility connections within the work area.
• 8" Sash Opening: Standard operating sash height for user access.
• HEPA Filtration: Ensures air quality for both supply and exhaust air.

4. Setup

Proper setup is crucial for the cabinet's performance and safety. Ensure the cabinet is placed on a stable, level surface. The unit is designed for floor mounting.

1. Unpacking and Inspection: Carefully unpack the cabinet and inspect for any shipping damage. Report any damage immediately.
2. Placement: Position the cabinet in a location free from drafts, high traffic, and direct sunlight. Ensure adequate clearance for maintenance access.
3. Electrical Connection: Connect the cabinet to a grounded 115 Volts, 60 Hz power supply.
4. Exhaust System (Optional Canopy Connection): If the cabinet will be used for applications involving minute quantities of volatile toxic chemicals and tracer amounts of radionuclides, it must be connected to an exhaust system via an optional Canopy Connection. This ensures that exhaust air is vented outside the laboratory.
5. Initial Cleaning: Before first use, thoroughly clean the interior work surfaces with an appropriate disinfectant.

5. Operating Instructions

Follow these steps for safe and effective operation of your biological safety cabinet:

1. Pre-Operation Check:
   • Ensure the sash is at the correct 8" operating height.
   • Verify that all internal surfaces are clean.
   • Confirm that the blower is operating and airflow indicators are within normal range.
2. Airflow Dynamics:

   During operation, room air is drawn into the inlet grill. This air, along with air from the work area, enters the plenum beneath the work surface. The contaminated air is then drawn by the blower through the back plenum. Approximately 70% of this air is recirculated through the supply HEPA filter and back over the work area, providing product protection. The remaining contaminated air is discharged to the environment after passing through the exhaust HEPA filter, providing environmental protection.

3. Working Safely:
   • Allow the cabinet to run for at least 5 minutes before beginning work to purge the work area.
   • Minimize arm movements in and out of the cabinet to maintain airflow integrity.
   • Place all materials as far back in the work zone as possible.
   • Avoid blocking the front or rear grilles.
4. UV Light Operation:

   The integrated UV light can be used for surface decontamination. Operate the UV light only when the cabinet is not in use and the sash is fully closed. Warning: Never operate the UV light with the sash open or personnel present, as UV radiation is harmful to skin and eyes.

5. Service Fixture Use:

   The service fixture provides access for gas, vacuum, or other utilities. Ensure proper connection and sealing to maintain cabinet integrity.

6. Post-Operation:

   After completing work, allow the cabinet to run for 5-10 minutes to clear any aerosols. Disinfect all interior surfaces. Turn off the UV light if it was used, and close the sash.

6. Maintenance

Regular maintenance is essential to ensure the continued safe and efficient operation of your biological safety cabinet.

• Surface Cleaning: Clean the interior work surfaces with an appropriate disinfectant before and after each use, and after any spills.
• HEPA Filter Replacement: HEPA filters have a finite lifespan. They must be inspected and replaced periodically by certified personnel. The frequency depends on usage and environmental conditions.
• Certification: The cabinet should be certified annually by a qualified professional to ensure proper airflow, filter integrity, and overall performance.
• UV Lamp Replacement: Replace the UV lamp when its effectiveness diminishes, typically after 6-12 months of regular use, or as indicated by the manufacturer.
