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+ HAS AN
OPTIONAL EN/CONTACT CIRCUIT BOARD THAT HAS DRY CONTACTS THAT
CAN BE CONFIGURED TO SIGNAL THE EXHAUST BLOWER TO TURN ON
WHEN THE LOGIC+’s 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+.
Before deciding on a location, examine it carefully to ensure that it accommodates
the cabinet’s exhaust duct. The area directly above the cabinet’s exhaust port
should be clear of structural elements, water and utility lines, or other fixed
obstructions. There should be enough clearance to allow for the passage of a 10"
stainless steel duct. Avoid cabinet locations that require either an elbow directly on
top of the cabinet’s exhaust connection or an excessive number of elbows to clear
other items. For a further discussion of the cabinet’s exhaust system
requirements, please go to Section 3: Getting Started.
Concurrent Balance Volumes (CBV)
NOTE: THE CBV IS ESTABLISHED BY NSF DURING LISTING TESTING. THE
STATIC PRESSURE LISTED IS MEASURED AT THE BSC’S CONNECTION TO
THE EXHAUST SYSTEM. THE VALUES PUBLISHED INCLUDES 0.7 INCHES

A dedicated outlet with an appropriate circuit breaker should be located as
close as possible to the right rear side of the cabinet, at a height even with,
or higher than, the top of the bench or stand. Consult your local electrical
codes for properly rated circuit breakers. For safe operation the dedicated
outlet must provide the protective earthing ground connection to the
cabinet.
On 100 and 115 VAC models, both internal electrical outlets are protected by a
ground fault interrupter circuit (GFIC). Labconco does not recommend plugging
the cabinet into a GFIC outlet.
Electrical outlets in the cabinet are restricted to 5 amps (115 Volt
models) or 2 amps (230 Volt models) maximum current.
Les prises électriques dans l'armoire sont limitées à 5 ampères
(modèles 115 volts) ou 2 ampères (modèles 230 volts) courant
maximum.
Do not use any detachable power cord that is not adequately rated for the
unit.

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 40 PSI, it must be equipped with a pressure regulator to reduce the line
pressure.
The use of flammable gases or solvents should be avoided in the cabinet. Open
flame in the cabinet will disrupt the laminar airflow in the cabinet and may damage
the HEPA filters. Flammable gases or solvents may reach explosive
concentrations in the cabinet or ductwork. If you feel that the procedure requires
the use of an open flame or flammable materials, contact the institution’s safety
office.
The use of air or gases under high pressure should be avoided as they may
seriously disrupt the airflow patterns in the cabinet.

Exhaust System Connections
The Purifier Logic Series Total Exhaust Biosafety Cabinets are a “Type B2
biosafety cabinet,” meaning they direct their HEPA filtered exhaust air out of the
laboratory.
WARNING: The Logic Total Exhaust Biosafety Cabinet is designed to
be connected to an appropriate exhaust system. Without verified inflow
velocity, the cabinet may NOT contain hazardous particulate or gasses. Do
not attempt to operate it when it is not connected to an appropriate exhaust
system that has been inspected by a qualified certifier.
WARNING: Type B2 Biosafety Cabinets rely on external blowers
(usually on the roof of a building) to exhaust 100% of the air entering the
cabinet. If the building exhaust blower fails or is mistakenly turned OFF, the
cabinet will become pressurized, resulting in a flow from the work area into
the laboratory. It is imperative that the following be considered in a risk
assessment:
Justify the type of work is appropriate for the cabinet Type B2.
Exhaust system must be reliable, maintained, frequently inspected
and preferably redundant.
Exhaust termination must be distant from other building air intake
systems to prevent the reintrainment of volatile chemicals.
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.
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 QuickChart (Appendix E). The exhaust
system must maintain a static pressure equal to or greater than the system
pressure, plus a pressure of 1.5 inches (38 mm) water for the Logic cabinet. In
order to get the maximum life out of the cabinet’s exhaust filter, the system needs
to be able to operate at an additional 2.0 inches (51 mm) of vacuum, compared to
the initial total system pressure.
NOTE: The exhaust system should be fitted with a backdraft damper
(Catalog Number 3858800) to prevent the reversing of airflow in the system.
LABCONCO MANUFACTURES EXHAUST BLOWERS AND A BACKDRAFT
DAMPER, WHICH ARE SUITABLE FOR MOST SINGLE CABINET
INSTALLATIONS. SEE APPENDIX D.
Connecting the Cabinet to Utility Service Lines
Note: Some models have a solenoid valve connected to the service valve on the
right side, rear position. The solenoid prevents gas from flowing to the service
valve when the unit blower is off, or there is a loss of electrical power. It is the only
service valve position that can be fitted with a solenoid valve. Connect the gas
service to the solenoid valve.
The service lines (if any) should be connected to the tube fitting(s) on the outside
of the liner wall as shown in Figure 3-1. 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. The slot is located from 8 ¾ to 11 ¼
inches (222 to 288 mm) from the bottom of the cabinet.
Note: Make sure that the tube routing will not contact any electrical wires. DO
NOT loop service line tubing within the side panels of the cabinet.
3. Make sure that the nut on the tube fitting is loose, but do not remove it. Make
sure the tube ferrule is in the fitting.

3: Getting Started
19
4. Push the tube into the fitting until it is properly seated. The tube will go
approximately ¾ inch (19 mm) into the fitting.
5. Tighten the tube fitting nut hand tight and then, using a 7/16-inch wrench,
tighten it at least ¾ turn more.
6. Close the service valve in the cabinet and then slowly open the shutoff valve
on the service valve. Test all fittings for leakage. Tighten the tube nut slightly if
needed.

Using the Optional Vacu-PassTM Cord & Cable Portal
There must be enough clearance to pass the cord or cable between the cabinet’s
exterior dress panel and any obstruction.
Note: Some Vacu-Pass components and the cord or cable passing through it may
become contaminated during use of the cabinet. Ensure all potentially
contaminated components are surface decontaminated before handling or removal
from the cabinet.
1. Remove the grommet from the liner sidewall. Remove the solid sealing plug
from the body of the portal by either pressing it through from the outside, or by
carefully inserting a spatula or similar device between the sealing plug and the
body of the portal, and prying the plug out.
2. Locate the pass-thru universal sealing plug, which is included in the parts box
located underneath the work surface during shipment.
3. Pass the cord or cable through the body of the portal, and then through one of
the holes in the pass-thru universal sealing plug, then through the grommet, as
shown in Figure 3-2.
Note: select a hole in the sealing plug that is slightly smaller than the cord or
cable, to create a proper seal. This will also help minimize movement of the cord
or cable if it is accidentally pulled during use.
4. Position the cord or cable as it will be used in the cabinet, and then push the
plug back into the body of the portal until it seats in the portal. Reinstall the
grommet.
