Exhaust System Connections
The Purifier Cell 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. 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. FOR FURTHER INFORMATION, CONTACT LABCONCO’S
PRODUCT SERVICE DEPARTMENT. AS AN ALTERNATIVE, A
REMOTE ELECTRICAL SWITCH FOR THE EXHAUST BLOWER CAN
BE INSTALLED NEAR THE LOGIC.
THE EXHAUST CONNECTION IS A SEALED EXHAUST SYSTEM
FROM THE TOP OF THE CABINET TO THE REMOTE BLOWER. THE
EXHAUST SYSTEMS SHOULD BE DEDICATED TO A SINGLE
CABINET. THE CABINET IS EQUIPPED WITH AN EXHAUST FLOW
ALARM, SUCH THAT AN ALARM SOUNDS, AND THE CABINET
BLOWER SHUTS OFF IN THE EVENT OF INSUFFICIENT EXHAUST
FLOW.
If your research involves the use of toxic compounds or volatile materials,
contact your facility’s safety officer or Labconco to ensure that your Purifier
and its exhaust system are compatible with the materials you will be working
with.
Drain Valve Installation
In order to prevent damage during shipping, the drain valve assembly has not
been installed. If desired, the valve should be installed after the Cabinet is in
its final location.
To install the valve assembly, follow these steps:
Note: The work surface is heavy. Use caution when handling it.
