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. 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 Chapter 3: Getting
Started.
Electrical Requirements
The different Biosafety Cabinet models have the following electrical
requirements:
Model # Requirements
3441000-3441009 115 VAC, 60 Hz, 12 Amps
3441020-3441029 230 VAC, 50/60 Hz, 6 Amps
3461000-3461009 115 VAC, 60 Hz, 12 Amps
3461020-3461029 230 VAC, 50/60 Hz, 6 Amps
Note: A dedicated outlet with a circuit breaker rated at 20 amps 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.
Note: On 115 VAC models, both electrical outlets are protected by a ground
fault interrupter circuit (GFIC). Labconco does not recommend plugging the
Biosafety Cabinet into a GFIC outlet.
