Congratulations on your purchase of a Labconco Purifier® HEPA Filtered Enclosure or Purifier® Class I Filtered Enclosure. Your enclosure provides personnel protection through superior containment. It is the result of Labconco’s more than 50 years experience in manufacturing fume hoods and more than 30 years experience in manufacturing filtered enclosures.
Chapter 5: Using Your Filtered Enclosure discusses the basic operation of how to prepare, use and shut down your filtered enclosure. Chapter 6: Maintaining Your Filtered Enclosure explains how to perform routine maintenance on the filtered enclosure. Chapter 7: Accessorizing Your Filtered Enclosure explains acceptable modifications to the filtered enclosure or how to add accessories.

Before you install the filtered enclosure, you need to prepare your site for installation. You must be certain that the area is level and of solid construction. In addition, a dedicated source of electrical power should be located near the installation site to power the filtered enclosure, and other apparatus.
Chapter 2: Prerequisites Support, Vibration and Movement Requirements At a minimum, the supporting structure usually consists of a base cabinet and chemically-resistant work surface. Location and Air Current Requirements The Purifier Filtered Enclosures have been designed to contain hazards by negating typical cross drafts and turbulence within the opening.

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.
Chapter 3: Getting Started Unpacking the Enclosure Carefully remove the shrink-wrap or carton on the enclosure and The United States inspect it for damage that may have occurred in transit. If Interstate Commerce Commission rules damaged, notify the delivery carrier immediately and retain the require that claims be entire shipment intact for inspection by the carrier.

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.
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.

Chapter 3: Getting Started Installation of HEPA Filters and Accessory Odor Control Carbon Filters HEPA Filters HEPA HEPA filters are shipped installed with the gasket on the downstream side. The HEPA filters are leak checked at Labconco. A second leak check is recommended before using the enclosure and at least annually thereafter.
Chapter 3: Getting Started HEPA Carbon Carbon Carbon Connecting the Electrical Supply Source to the Filtered Enclosure 115V Models Simply connect the 115V power cord supplied to the IEC electrical supply plug on the back of the enclosure. If using at 50 Hz operations, blower performance maximum airflow will be reduced by 17%.
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).
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 10 Niger were released in the enclosure and appropriate air sampling equipment established the number of spores that escaped through the sash opening.

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.

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.
