CHAPTER 3 GETTING STARTED Now that the site for your filtered enclosure is properly prepared, you are ready to unpack, inspect, install, and validate your system. Read this chapter to learn how to: • Unpack and move the enclosure. • Set up the enclosure with the proper supporting structure and work surface. • Connect to an exhaust system if applicable. • Installation of HEPA and accessory Odor Control carbon filters. • Connect the electrical supply. • Set the face velocity with the speed control adjustment.
Chapter 3: Getting Started Unpacking the Enclosure The United States Interstate Commerce Commission rules require that claims be filed with the delivery carrier within fifteen (15) days of delivery. Carefully remove the shrink-wrap or carton on the enclosure and inspect it for damage that may have occurred in transit. If damaged, notify the delivery carrier immediately and retain the entire shipment intact for inspection by the carrier. ☞ DO NOT RETURN GOODS WITHOUT THE PRIOR AUTHORIZATION OF LABCONCO.
Chapter 3: Getting Started 0.36" of the front of the work surface. Mounting holes are provided in the Labconco accessory work surfaces to secure the enclosure. Work Surface Specifications The work surface should be smooth, rigid, and durable, such as a chemical-resistant epoxy resin. The surface should be non-porous and resistant to the biohazards, powders, solvents and chemicals used in conjunction with the Purifier Filtered Enclosure.
Chapter 3: Getting Started Figure 3-1 Filtered Enclosure Installation 12
Chapter 3: Getting Started Connecting to the Exhaust System (Optional) ! WARNING: The weight of the exhaust ductwork system must be supported independently of the enclosure superstructure or damage may occur. The exhaust system should be installed by a qualified HVAC contractor. Exhaust transition kits aid in the removal of chemicals or applications where a higher degree of biohazard and particulate removal is required.

Adsorbs organic compounds designated by NIOSH guidelines as acceptable for use with chemical cartridge-type respirators.
Chapter 3: Getting Started Set the Face Velocity with the Speed Control Adjustment Adjustment of the speed control gives the correct face velocity and is located behind the front panel. The face velocity should be from 75 to 105 fpm for biohazardous operations. (Consult your Safety Officer for airflow recommendations for your application). Containment is maximized at a setting within this range. Working at the lowest face velocity appropriate for the application will give the quietest operation.
Chapter 3: Getting Started The Purifier Enclosures were also subjected to Biological Containment testing, using a modified Personnel Protection Test, as described in NSF/ANSI Standard Number 49. An aerosol challenge of approximately 5 x 108 spores of Bacillus subtilus var Niger were released in the enclosure and appropriate air sampling equipment established the number of spores that escaped through the sash opening. Each size enclosure was tested three times.
CHAPTER 4 HIGH PERFORMANCE FEATURES AND SAFETY PRECAUTIONS High Performance Features: The patented* Purifier HEPA Filtered Enclosure and Purifier Class I Enclosure are designed to meet the needs of the laboratory scientist, and provide superior containment while operating at velocities between 75-105 feet per minute. The filtered enclosures have been tested to effectively contain toxic, noxious, and biohazardous materials when properly installed and operated.
Chapter 4: High Performance Features and Safety These concentrations of materials are predominantly removed on the “first pass” of airflow through the chamber resulting in high performance containment. The plenum and the HEPA filter are jacketed by negative pressure. Should a leak occur in the filter gasket or the plenum, the contaminated air is recaptured and refiltered. The Purifier Class I Enclosure and Purifier HEPA Filtered Enclosure have an access port located behind the front panel.

Chapter 4: High Performance Features and Safety Figure 4-2 HEPA Filtered Enclosure Airflow Diagram 22
Chapter 4: High Performance Features and Safety 1. Aerodynamic Clean-Sweep™ Air Foil has a unique shape that allows air to sweep the work surface for maximum containment. The Clean-Sweep™ openings create a constant protective barrier from contaminants. Should the operator inadvertently block the airflow entering the air foil, air continues to pass under the air foil and through the Clean-Sweep openings. See Figures 4-1 and 4-3. Figure 4-3 2.
Chapter 4: High Performance Features and Safety 3. Upper Dilution Air Supply provides bypass air from above the work area. This feature constantly bathes the inside of the sash with clean air and reduces powders, particulate materials and chemical fumes along the sash plane, near the critical breathing zone. Five to seven percent of the required air volume is introduced through the upper dilution air supply. The upper dilution air supply also reduces stagnant pockets of air in the upper interior.
Chapter 4: High Performance Features and Safety Monitor is an available option on all Purifier models. See Figure 4-1 and 4-2. 11. Inherently Safe Impeller has a negative pressure plenum that surrounds the positive pressure impeller so that if a leak should occur, the unfiltered air is captured and refiltered. See Figure 4-2. 12. Vibration-Isolated Motorized Impeller has vibration isolation supports, which eliminates transfer of vibration to the work surface.
Chapter 4: High Performance Features and Safety 21. Lamp Ballast (Not Shown) for the fluorescent lamp is located behind the control panel. 22. UV (Ultraviolet) Lamp (Not Shown), found only on Purifier Class I Enclosure, allows the operator to surface disinfect the work area of the enclosure when it is not in use. The UV will not penetrate the plane of the sash and lower airfoil. 23. Accessory Work Surface (Not Shown) is dished and contoured to fit the dimensions of the enclosures to contain spills. 24.
Chapter 4: High Performance Features and Safety Safety Precautions 1. Although the enclosure has been engineered to maintain optimum operator safety, caution should always be used while working. Prior to using the enclosure, check to make sure that the exhaust blower is operating and that air is entering the enclosure at its specified face velocity. The use of an airflow monitor is recommended to alert the user to a problem with airflow. 2. Use good housekeeping in the enclosure at all times.
Chapter 4: High Performance Features and Safety 11. The use of safety goggles, protective clothing, gloves and any other personal protective equipment recommended by your safety officer should be used. 12. The sash must remain in the down position while using the enclosure. 13. Proper performance of the enclosure depends largely upon its location and the operator’s work habits. Consult the references in Appendix D. 14.
Chapter 4: High Performance Features and Safety 19. The HEPA filter in the enclosure will gradually accumulate airborne particulate matter from the room and from work performed in the enclosure. The rate of accumulation will depend upon the cleanliness of the room air, the amount of time the enclosure is operating and the nature of work being done in the enclosure. With normal usage, the HEPA filters will last two to five years before requiring replacement. 20.
Chapter 4: High Performance Features and Safety 28. Only nuisance powders, biohazardous and particulates removed by HEPA filters and trace chemicals which can be safely adsorbed and treated with specific carbon based filters are appropriate for use in this enclosure. 29. The warning properties (i.e., odor, taste) of the volatile organic compounds or other material being used in the enclosure must be adequate to provide an early indication that the carbon filter may be saturated or inadequate.
