Chapter 3: Getting Started ADJUSTMENT ESTABLISHES THE DESIRED FACE VELOCITY (FPM), AND AS THE HEPA FILTERS LOAD, THE MOTOR WILL SPEED UP TO MAINTAIN THE DESIRED FACE VELOCITY. HAVE THE FACE VELOCITY CHECKED AT LEAST ANNUALLY AS INDICATED IN CHAPTER 6: MAINTAINING YOUR XT CLEAN BENCH. REPLACE HEPA FILTERS WHEN FACE VELOCITY DROPS BELOW DESIRED RANGE. If you have any questions regarding certification agencies or need assistance in locating one, contact Labconco’s Product Service Department at 1-800-821-5525.
Chapter 3: Getting Started Moving XT Clean Bench through Tight Doorway ) MAKE SURE THERE IS NO ALTERNATE DOORWAY OF GREATER WIDTH. DISASSEMBLY OF UNIT INVOLVES SIGNIFICANT TIME AND LIFTING OF HEAVY COMPONENTS. To remove the Side Windows: 1. Obtain a T20 Torx Head Driver Bit and electrical screwdriver or drill. 2.

Reinstall components in reverse to reassemble the XT Clean Bench.
CHAPTER 4 THEORY OF OPERATION AND SAFETY PRECAUTIONS All clean benches operate using the following principles: • Filtration and retention of particulates by High Efficiency Particulate Air (HEPA) filter(s) • Laminar airflow The major components in a clean bench are: • The HEPA filter • The motor/blower to force air through the unit • A speed control for the motor HEPA Filters HEPA filters are disposable, dry-type particulate filters.
Chapter 4: Theory of Operation and Safety Precautions HEPA Filters are only effective against particulate material. Gases will pass through the filter. ! Le matériel du filtre HEPA est très fragile. Ne pas toucher ou être en contact avec la surface du matériel. Si vous pensez que la surface d’un filter HEPA est endommagé, NE PAS UTILISER L’HOTTE. Faire tester l’intégrité du filter HEPA par un certificateur qualifié avant d’utiliser l’hotte.
Chapter 4: Theory of Operation and Safety Precautions Laminar Airflow Laminar airflow is defined as the movement of a body of air in a single direction, with a uniform velocity. In practice, the horizontal laminar flow of sterile air in the clean bench flushes out any aerosol generated in the work area of the bench. This sterile airflow maintains the sterility of sterile items inside the clean bench.
Chapter 4: Theory of Operation and Safety Precautions Speed Control ! The speed control should only be adjusted by a qualified certifier. ! Le contrôle de la vitesse doit être réglée uniquement par un certificateur qualifié. The speed control is an electronic circuit that allows the certifier to set the air face velocity (fpm) by adjusting its voltage. ) THE XT CLEAN BENCH USES A SELF-ADJUSTING ECM MOTOR TO MAINTAIN AIRFLOW ACROSS THE WORK AREA.
Chapter 4: Theory of Operation and Safety Precautions infectieuses, des toxins ou des radionucléides. L’opérateur et l’oficiel de sécurité competent doivent soigneusement évaluer le risque associé à tous les opérations effectuées dans un hotte à flux laminaire. The Purifier XT Clean Bench should be certified by a qualified certification technician before its initial use. The clean bench should be recertified whenever it is relocated, serviced, or at least annually thereafter.
Chapter 4: Theory of Operation and Safety Precautions d’air dams l’hotte. Gaz sous haute pression ne doit pas être utilisé dans l’hotte, car il peut interrompre le ciruit du courant d’air dans l’hotte. La surface du filtre HEPA est fragile et ne doit pas être touchée. Faites attention de ne pas percer le filtre HEPA lors de l’installtion ou le fonctionnement normal. Si vous pensez que le filtre HEPA a été endommagé.
