2 Chapter 1: Introduction filtered enclosures include a true bag-in/bag-out HEPA filter to properly protect personnel during filter changing operations. See chart below and contact Labconco for additional ordering information. No. Application Product Filters Bag-in/Bag-out HEPA UV Light 1.
3 Chapter 1: Introduction About This Manual This manual is designed to help you learn how to install, use, and maintain your filtered enclosure. Instructions for installing optional equipment or accessory carbon filters on your filtered enclosure are also included.
4 Chapter 1: Introduction Appendix C: Specifications contains the electrical requirements for filtered enclosures. Wiring diagram s are also included. Appendix D: Quick Chart provides an airflow table and test data for the filtered enclosures.
5 C C H H A A P P T T E E R R 2 2 P P R R E E R R E E Q Q U U I I S S I I T T E E S S Before you install the filtered enclosure, you need to prepare your site for installation.
6 Chapter 2: Prerequisites Support, V ibration and Movement Requirement s At a minimum , the supporting structure usually consists of a base cabinet and chemical-resistant work surface. The ability for analytical balances to accommodate vibration varies with type and brand.
7 Cha p ter 2: Prere q uisite s Humidity and S t atic Electricity Requirement s Electrostatics can be troublesome in a balance enclosure. It is important to understand and, to the extent possible, control static charges. An electrostatic charged vessel, sample or enclosure can apply forces and lead to errors in weighing.
8 Chapter 2: Prerequisites The ability of a material to become polarized is a property known as permittivity . On highly insulative materials like acrylic, ions or charged molecules are strongly bound to the surface by polarization forces. The higher the force, the higher is the permittivity value of the material.
9 Cha p ter 2: Prere q uisite s The HEPA-filtered exhaust air can be recirculated into the laboratory or exhausted outside with the addition of the exhaust connection kit and remote blower listed in Chapter 7. The XPert Filtered Balance Station does not include the motorized impeller and must be exhausted to the outside by a rem ote blower.
10 Chapter 2: Prerequisites Proper blower selection can be determined from these exhaust requirements and the total system static pressure loss. For outside exhaust, the enclosure must be connected to either a dedicated blower or a house exhaust system.
11 C C H H A A P P T T E E R R 3 3 G G E E T T T T I I N N G G S S T T A A R R T T E E D D 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.
12 Chapter 3: Getting Started Unp acking the Enclosure 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 imm ediately and retain the entire shipment intact for inspection by the carrier.
13 Cha p ter 3: Gettin g Starte d 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.

18 Chapter 3: Getting Started Inst allation of HEP A Filters and Accessory Odor Control Carbon Filters HEPA Filters 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.
19 Cha p ter 3: Gettin g Starte d Filter Type Appropriate Use HEPA 2' 3707900 3' 3707901 4' 3707902 HEPA filters are high-efficiency particulate air filters having a particulate removable efficiency of 99.99% for particles with a diameter of 0.
20 Chapter 3: Getting Started The maximum circuit load for the electrical relay is 6 amps. Only the remote blower wiring is connected inside the electrical junction box. The lights and airflow monitor are powered from a standard duplex electrical receptacle located nearby for connecting the power cord.
21 Cha p ter 3: Gettin g Starte d 230V Models The same procedure applies for the 230V except it is shipped without a plug. Install the appropriate plug for your electrical specifications per local codes.
