Page 6: Chapter 1: Introduction
Congratulations on your purchase of a Labconco Purifier Digital Delta Series Biosafety Cabinet. Your Purifier is designed to protect you, your product and your laboratory environment from biohazardous aerosols. The Delta is the result of years of experience in manufacturing biohazard cabinetry, and users like you suggested many of its features to us. -
Page 7: Chapter 2: Prerequisites
Before you install your biosafety cabinet, you need to prepare your site for installation. Carefully examine the location where you intend to install your 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. -
Page 8: Space Requirements
Chapter 2: Prerequisites Space Requirements The dimensions for the different models are shown in Appendix B: Dimensions. Clearance Deltas not connected to an exhaust system should have at least six inches (150 mm) clearance from any overhead obstructions when the cabinet is in its final operating position. -
Page 9: Electrical Requirements
Note: Both electrical outlets of the 115 volt Purifier are protected by a ground fault interrupter circuit (gfic). Labconco does not recommend plugging the Purifier into a gfic outlet. -
Page 10: Service Line Requirements
Chapter 2: Prerequisites Service Line Requirements All service lines to the Purifier should be ¼ inch outside diameter, metal, and equipped with an easily accessible shut-off valve, should disconnection be required. If the service line pressure exceeds 40 PSI, it must be equipped with a pressure regulator to reduce the line pressure. - Page 11 Now that the site for your biosafety cabinet is properly prepared, you are ready to inspect, install, and certify your unit. This chapter covers how to: • Unpack and move your Purifier. • Set up the cabinet. • Connect the electrical supply source. •...

Page 12: Chapter 3: Getting Started
Unauthorized returns will not be accepted. If your cabinet was damaged in transit, you must file a claim directly with the freight carrier. Labconco Corporation and its dealers are not responsible for shipping damages. Do not discard the carton or packing material for your Purifier until you have checked all of the components and installed and tested the unit. - Page 13 User’s Manual Drain Valve Assembly Power Cord If you did not receive one or more of the components listed for your Cabinet, or if any of the components are damaged, contact Labconco Corporation immediately for further instructions.

Page 14: Moving The Delta
Installing the Purifier on a Labconco Base Stand Labconco offers a variety of accessory base stands in a number of configurations to suit your particular needs. Stands can be ordered with preset telescoping legs or, with a manually or electrically adjustable hydraulic lift stand. -
Page 15: Telescoping Base Stands
Chapter 3: Getting Started Telescoping Base Stands These stands are available with either fixed feet or caster wheels. The height of these stands is set before installation of the Delta. The height can be set at 27.5 to 33.5 inches in 1-inch intervals, providing a work surface height of 30.0 to 36.0 inches. -
Page 16: Manual Or Electric Hydraulic Lift Base Stands
Chapter 3: Getting Started 3. Move the base stand into its final location. Using a carpenter’s level, adjust each leveling foot until the stand is level in both planes as shown in Figure 3-2. You are now ready to lift the Purifier onto its stand. Figure 3-2 Manual or Electric Hydraulic Lift Base Stands These base stands offer infinitely adjustable height between 25.5 and 33.5... -
Page 17: Connecting The Purifier To Service Lines
Chapter 3: Getting Started Note: When installing the hydraulic lift base stand, ensure that the hydraulic lines and the electrical cord are clear of any obstructions before installing the cabinet on the stand or operating the lift system. Connecting The Purifier to 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. -
Page 18: Optional Exhaust System Connections
Chapter 3: Getting Started Optional Exhaust System Connections Unless specially modified by Labconco at your request, all Purifier Delta Series Biosafety Cabinets are shipped in the “Type A mode,” meaning they recirculate their HEPA filtered exhaust air back into the laboratory. - Page 19 Chapter 3: Getting Started 4. Make sure the drain valve is in the closed position. 5. Reinstall the work surface. 6. Allow the silicone sealant to cure for at least eight hours before exposing it to liquid.

Page 22: Chapter 4: Performance Features And Safety Precautions
Chapter 4: Performance Features and 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. - Page 23 Chapter 4: Performance Features and Safety Precautions Figure 4-2 Product Service 1-800-522-7658...
-
Page 24: Directional Airflow
Chapter 4: Performance Features and 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. -
Page 25: Motor/Blower
Chapter 4: Performance Features and Safety Precautions Motor/Blower The motor/blower assembly pulls air into the front of the cabinet, and re- circulates it internally. During its recirculation, the air is split into two separate streams. One path leads through the exhaust HEPA filter and out of the unit. -
Page 26: Ultraviolet (Uv) Lamp
If you have any questions regarding certification agencies, or need assistance in locating one, contact Labconco’s Product Service Department at 800-522-7658 or 816-333-8811. Ensure that the unit is connected to electrical service in accordance with local and national electrical codes. - Page 27 HEPA filter during installation or normal operation. If you suspect that a HEPA filter has been damaged, DO NOT use the cabinet; contact a local certification agency or Labconco at 800-821-5525 or 816-333- 8811 for re-certification information. The HEPA filters in the purifier cabinet will gradually accumulate airborne particulate matter from the room and from work performed in the cabinet.

Page 29: Chapter 5: Using Your Cabinet
Operating the Sliding Sash The Purifier's counterbalanced, anti-racking sash mechanism requires only a few pounds of force to move the sash up or down. You can open or close the sash smoothly with one or two hands positioned any where along the handle. The sash position alarm and safety interlock system senses the sash position and acts appropriately. - Page 30 Chapter 5: Using Your Cabinet Figure 5-1 2. Press the blower button to start the unit. The unit will run a self-test for approximately two minutes. If the alarm sounds, recheck the sash position. If the sash is too high, the sash audible alarm and the LCD display will indicate the sash is too high.
- Page 31 Chapter 5: Using Your Cabinet The touchpad of the Digital Delta is shown in Figure 5-2. Take a moment to get familiar with the buttons, their location and function. Also familiarize yourself with the display located on the right side wall. The display will report system operation, such as inflow and downflow velocities, timer displays, alarm or error messages, as well as icons that illuminate when that part of the Purifier is operational (UV light or blower, for example).
