CHAPTER 1 INTRODUCTION Congratulations on your purchase of a Labconco XPert™ Filtered Balance System or XPert™ Filtered Balance Station. Your enclosure provides personnel protection through superior containment while conserving energy at OSHA approved velocities as low as 60 feet per minute. 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 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. 1. 2.
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. Chapter 1: Introduction provides a brief overview of the filtered enclosure, explains the organization of the manual, and defines the typographical conventions used in the manual.
Chapter 1: Introduction Appendix C: Specifications contains the electrical requirements for filtered enclosures. Wiring diagrams are also included. Appendix D: Quick Chart provides an airflow table and test data for the filtered enclosures. Appendix E: References lists the various resources available that address laboratory ventilation and biosafety.
CHAPTER 2 PREREQUISITES 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, balance and other apparatus. Additionally, the enclosure should be strategically placed in the lab to provide efficient workflow.
Chapter 2: Prerequisites Support, Vibration and Movement Requirements 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. More advanced balances have improved tolerance, however in the preparation of a balance enclosure site, please consider the following: • • • • • • • Avoid tubular stands or mobile benches that have the potential of moving when touched.
Chapter 2: Prerequisites Humidity and Static Electricity Requirements 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. The repulsion or attraction can be detected with micro, semi micro and analytical balances. Static charges can also lead to particulates being attracted to surfaces within the balance enclosure.
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. It is suggested by balance manufacturers that the use of high permittivity materials, such as plastic be avoided.
Chapter 2: Prerequisites 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 remote blower. The XPert Filtered Balance Station remote blower may be switched from the blower switch on the enclosure.
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. Labconco offers accessory remote blowers listed in Chapter 7. Contact Labconco for blower sizing assistance. ! If the enclosure is connected directly to a house exhaust system, an adjustable damper (or valve) must be installed to control the airflow properly.
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 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. All wiring for the XPert Filtered Balance Station should be performed by a licensed electrician and conform to local codes.
Chapter 3: Getting Started 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. Set the Face Velocity with the Speed Control Adjustment For XPert Filtered Balance Systems, adjustment of the speed control gives the correct face velocity and is located behind the front panel. The face velocity should be adjusted from 60 to 100 fpm for weighing operations.
Chapter 3: Getting Started individual ratings). For “field use” ASHRAE testing contact Labconco for a certified on-site contractor. For particulate powder validation, Labconco had containment testing performed to validate the enclosures for sodium naproxen powders. The XPert HEPA filtered enclosures demonstrated excellent containment when used by an operator using excellent technique and good containment when used by an operator using marginal technique.
CHAPTER 4 HIGH PERFORMANCE FEATURES AND SAFETY PRECAUTIONS High Performance Features: The patented* XPert Filtered Balance System and XPert Filtered Balance Station are designed to meet the needs of the laboratory scientist, and provide superior containment while conserving energy at OSHA approved “low flow” velocities as low as 60 feet per minute. The filtered enclosures have been tested to effectively contain toxic and noxious 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. 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 also displays a face velocity value, provides an RS232 output, a night setback mode and several auxiliary relay ports. Both airflow monitors are available options on all XPert 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.
Chapter 4: High Performance Features and Safety 20. HEPA (High Efficiency Particulate Air) Filter is rated to remove 99.99% of all particles 0.3 micron in size. See Figure 4-2. 21. Lamp Ballast (Not Shown) for the fluorescent lamp is located behind the control panel. 22. Accessory Work Surface (not shown) is dished and contoured to fit the dimensions of the enclosures to contain spills. 23.
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 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. The enclosure should be recertified whenever it is serviced or at least annually thereafter. 15. The HEPA filter provides personnel and environmental protection from particulate matter.
Chapter 4: High Performance Features and Safety 20. Ensure that the filtered enclosure is connected to an electrical service in accordance with local and national electrical codes. Failure to do so may create a fire or electrical hazard. Do not remove or service any electrical components without first disconnecting the filtered enclosure from electrical service. 21. Use of an open flame must be avoided with the enclosure.
Chapter 4: High Performance Features and Safety 29. Use the smallest possible quantity of chemical(s) within the enclosure and never exceed the amount, which can be effectively adsorbed by the Odor Control carbon filter before breakthrough. 30. For weighing procedures, adjust face velocity between 60 and 100 FPM for effective operation. 31. Leave the blower on for at least one minute after work in the enclosure has been completed. 32.
