Chapter 1: Introduction Congratulations on the purchase of a Labconco Purifier Logic Series Total Exhaust Biosafety Cabinet. The Biosafety Cabinet is designed to protect you, the product and the laboratory environment from biohazardous aerosols. The Logic Series Cabinet is the result of years of experience in manufacturing biohazard cabinetry, and users like you suggested many of its features to us. The Biosafety Cabinet offers many unique features to enhance safety, performance and ergonomics.
Chapter 2: Prerequisites Before you install the Biosafety Cabinet, you need to prepare the site for installation. Examine the location where you intend to install the cabinet. You must be certain that the area is level and of solid construction. In addition, a dedicated source of electrical power must be located near the installation site. Carefully read this chapter to learn: • Location requirements. • Electrical power requirements. • Exhaust requirements. • Service utility requirements.
Chapter 2: Prerequisites Location Requirements Note: The Biosafety Cabinet should be located away from traffic patterns, doors, fans, ventilation registers, fume hoods and any other air-handling devices that could disrupt its airflow patterns. All windows in the room should remain closed. Figure 2-1 shows the preferred location for the Biosafety Cabinet.
Chapter 2: Prerequisites Exhaust Requirements NOTE: THE EXHAUST BLOWER CANNOT RUN AT ITS NOMINAL FLOW RATE WITH THE SASH COMPLETELY CLOSED. IF YOU CHOOSE TO CLOSE THE SASH COMPLETELY TO USE THE UV LIGHT FOR SURFACE DISINFECTION, THEN THE EXHAUST BLOWER MUST BE SHUT OFF, OR ITS FLOW RATE REDUCED 90% OR MORE FOR PROPER OPERATION. THE LOGIC CONTROL BOARD HAS DRY CONTACTS THAT CAN BE CONFIGURED TO SIGNAL THE EXHAUST BLOWER TO TURN ON WHEN THE LOGIC BLOWER IS ON.
Chapter 2: Prerequisites Service Line Requirements All utility service lines should be ¼ inch O.D., brass, copper, or stainless steel, and equipped with an easily accessible shut-off valve. If the service line pressure exceeds 100 PSI, it must be equipped with a pressure regulator to reduce the line pressure. Note: The use of flammable gases or solvents should be avoided in the Biosafety Cabinet. Open flame in the cabinet will disrupt the laminar airflow in the cabinet and may damage the HEPA filters.
Chapter 3: Getting Started Now that the installation is properly prepared, you are ready to inspect, install, and certify the Purifier Biosafety Cabinet. This chapter covers how to: • Unpack and move the Biosafety Cabinet. • Install the cabinet. • Connect the electrical supply source. • Connect the service lines. • Connect to an exhaust system. • Arrange certification of the Biosafety Cabinet.
Chapter 3: Getting Started Unpacking the Biosafety Cabinet Carefully remove the outer carton and inspect the cabinet for damage that may have occurred in transit. If the Biosafety Cabinet is damaged, notify the delivery carrier immediately and retain the entire shipment intact for inspection by the carrier. Note: United States Interstate Commerce Commission rules require that claims be filed with the delivery carrier within fifteen (15) days of delivery.
Chapter 3: Getting Started Preparing the Biosafety Cabinet for Operation Installation instructions for the cabinet (Labconco P/N 1056801) are attached to the sash of the Biosafety Cabinet. If these instructions are missing or unclear, contact Product Service at 800-821-5525 or 816-333-8811. Installing the Biosafety Cabinet on an Existing Work Surface Note: The Biosafety Cabinet is very top heavy. Use caution when lifting or moving it.
Chapter 3: Getting Started 2. Select the height of the stand and slide four (4) leg extensions into base stand corner posts and attach with 2 ¼ inch long bolt, flatwasher, lockwasher and nut. Ensure that the same height hole is selected for each leg. Tighten the leg bolts securely. See Figure 3-1. Figure 3-1 3. CAUTION: Only lift and support the weight of the cabinet at the stainless steel sides and back. Damage will occur if lifted or supported on the front edge.
Chapter 3: Getting Started Connecting the Biosafety Cabinet to Utility Service Lines The service lines (if any) should be connected to the tube fitting(s) on the outside of the liner wall as shown in Figure 3-3. To install the tubing, follow these steps: 1. Ensure that the tubing is ¼ inch O.D., soft metal, and that the end has been completely deburred. 2. Route the tubing from the rear of the cabinet, ensuring that it will line up with the slot in the back of the side panel.
Chapter 3: Getting Started Exhaust System Connections The Purifier Logic Series Total Exhaust Biosafety Cabinets are a “Type B2 cabinet,” meaning they direct their HEPA filtered exhaust air out of the laboratory. Note: The Logic Total Exhaust Biosafety Cabinet is designed to be connected to an appropriate exhaust system. Do not attempt to operate it when it is not connected to an appropriate exhaust system. NOTE: THE EXHAUST BLOWER CANNOT RUN AT ITS NOMINAL FLOW RATE WITH THE SASH COMPLETELY CLOSED.
Chapter 3: Getting Started Exhaust System Requirements The cabinet exhaust stack is sized to accept 10-inch (254 mm) stainless steel ductwork. The exhaust system’s blower should be sized to handle the exhaust volume of each cabinet, as shown in the QuickCharts, Appendix E. The exhaust system must maintain a static pressure equal to or greater than the system pressure, plus 1.5 inches (38 mm) of water for the Logic cabinet.
Chapter 3: Getting Started Figure 3-4 NOTE: The drain valve assembly attaches to the underside of the cabinet bottom. Apply a light coat of silicone sealant to this surface of the connector, aligning the three holes in the connector with the three holes in the Biosafety Cabinet liner. Initial Certification Prior to use, a qualified certifier should certify all Biosafety Cabinets.
Chapter 4: Performance Features and Safety Precautions All Purifier Series Logic Biosafety Cabinets operate using the following principles: • Filtration and retention of particulates by High Efficiency Particulate Air (HEPA) filter(s) • Laminar airflow • Directional airflow The major components in a Biosafety Cabinet are: • The HEPA filter(s) or optional ULPA filters • The motor/blower to force air through the Cabinet • Cabinet air intakes (grilles), ductwork and air balance controls HEPA Filter
Chapter 4: Performance Features & Safety Precautions Note: The HEPA filter media is very fragile. DO NOT touch the media. If you think the media of a HEPA filter is damaged, DO NOT USE THE CABINET. Have the HEPA filter integrity tested by a certifier before using the cabinet. Note: HEPA Filters are only effective against particulate material. Gases will pass through the filter.
Chapter 4: Performance Features & 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 laminar downflow of air in the cabinet captures any aerosol generated in the work area of the cabinet, and directs it to the HEPA filters. In order to be true laminar downflow, a number of individual downflow velocity test points (The Downflow Velocity Profile) must be +/- 16 feet per minute (0.
Chapter 4: Performance Features & Safety Precautions Directional Airflow Directional airflow also plays a key role in biosafety cabinet performance. Air is drawn into the front of the cabinet at the front grille. This “curtain” of air makes it more difficult for aerosols to escape out of the work area of the cabinet and into the outside environment. This airflow is often calculated and referred to as the Inflow Volume or Average Inflow Velocity. This is illustrated in Figure 4-3.
Chapter 4: Performance Features & Safety Precautions Motor/Blower The motor/blower assembly pulls air through the top of the cabinet, and is sent through the supply HEPA filter. The filtered air flows down through the work area where it provides a clean environment to perform work. Room air is drawn into the front intake grille. All of the air is then drawn through an exhaust HEPA filter and out of the laboratory, as shown in Figure 4-4.
Chapter 4: Performance Features & Safety Precautions Airflow Sensor An airflow sensor, located above the Exhaust HEPA filter, constantly monitors the flow of exhaust air out of the cabinet. If the exhaust falls below a safe level, the control board turns off the cabinet blower, and sounds an audible and visual alarm. This prevents the escape of hazardous material from the front of the cabinet, in the event of an exhaust system failure.
Chapter 4: Performance Features & Safety Precautions Safety Precautions WARNING: The Biosafety Cabinet should be certified by a certification technician before its initial use. The cabinet should be recertified whenever it is relocated, serviced or at least annually thereafter. Do not assume that filter integrity and airflow performance have not been compromised during shipping. Some internal components of the Biosafety Cabinet may become contaminated during operation of the unit.
Chapter 4: Performance Features & Safety Precautions Proper operation of the cabinet depends largely upon its location and the operator’s work habits. Consult the Installation and Normal Operation sections of this manual for further details. Avoid direct exposure of plastic or coated materials to ultraviolet (UV) radiation. Never bypass the UV safety interlock that only allows the UV light to work when the sash is closed.
Chapter 5: Using the Cabinet System Reset Switch The Biosafety Cabinet has a system reset switch for resetting its microprocessors. The switch is located on the front of the electronics module, on top of the Cabinet, as shown in Figure 5-1. Ensure that the switch is in the “ON” (up) position before attempting to operate the Cabinet.
Chapter 5: Using The Cabinet Information Center The Information Center is an LCD display located on the right side wall at eye level. The center’s display is divided into three separate areas, as shown in Figure 5-2, below. The display will turn itself off one minute after the blower is turned off or the sash is closed. Figure 5-2 Status Area Data Area Icon Area Status Area The Status Area displays the system’s condition during operation, as well as the inflow velocity.
Chapter 5: Using The Cabinet Exhaust Error If the volume of exhaust air leaving the cabinet falls below a safe level, this message is displayed, the cabinet blower turns off, and an audible alarm sounds. Pressing the “Blower” button will restart the blower. If there is still insufficient airflow, the alarm will sound again. IF THE CABINET KEEPS GOING INTO EXHAUST ERROR, DO NOT USE THE CABINET UNTIL THE PROBLEM HAS BEEN CORRECTED.
Chapter 5: Using The Cabinet UV light In this mode the UV (germicidal) light is operating. When the sash is fully closed, the UV light can be programmed to automatically turn on. When the sash is raised, the light automatically turns off, to protect the laboratory from UV irradiation. Timer When either the interval or stopwatch timer mode is active, this icon appears.
Chapter 5: Using The Cabinet Starting the Biosafety Cabinet 1. To start the Biosafety Cabinet, raise the sash until its bottom edge aligns with the sash position label on the left corner post. The decal is shown in Figure 5-3. 2. Press the blower button to start the unit. The unit will run a self-test for approximately 15 seconds. Additionally, you will be instructed to “Please Wait” for three minutes to allow the cabinet to reach proper operating conditions.
