5.0 Installation Instructions
5.1 Location
Within the laboratory, pharmacy, etc., the ideal location of the Biosafety cabinet is away from personnel traffic lanes, air
vents (in or out), doors and/or any other source of disruptive air currents.
Suggested Cabinet Location in Laboratory
THE EXHAUST FILTER AREA IS ESPECIALLY SUSCEPTIBLE TO DISRUPTIVE AIR CURRENTS FROM AIR VENTS. The exhaust
sensor for the Electronic Airflow Control System is located just above the exhaust HEPA filter and if disruptive air currents
are present, the exhaust sensor could be influenced by them, and indicate disruptive readings on the front panel display.
If drafts or other disruptive air currents exceed the inflow velocity of the cabinet through the access opening, the potential
exists for contaminated air to exit or enter the work zone area of the cabinet. It depends on the severity of the air current.
REMEMBER: A BIOSAFETY CABINET IS NO SUBSTITUTE FOR GOOD LABORATORY TECHNIQUE.
Where space permits, a clear 6" (152mm) area should be permitted on each side of the cabinet for maintenance purposes.
The electrical outlet into which the cabinet is connected should be readily accessible for maintenance purposes.
Do not
position the cabinet to prevent access to the power cord. The power cord plug serves as the disconnect and should
remain readily accessible. If the outlet is inaccessible, such as a conduit (hardwired) connection, then an appropriate
warning label should be applied near the cabinets on/off switch to indicate the circuit breaker on the power distribution
panel should be used. A MINIMUM CLEARANCE OF 6" (152MM) IS REQUIRED FROM THE TOP OF THE CABINET TO THE
CEILING FOR PROPER VENTILATION OF THE EXHAUST EFFLUX.
If this cabinet is used in a pharmacy application, it is strongly recommended (Per OSHA, NIOSH and ASHP) that the cabinet
be exhausted to the outside. In addition, if this cabinet is used in microbiological application with minute quantities of
volatile toxic chemicals and trace amounts of radionuclides, per CDC/NIH and NSF, it is strongly recommended that the
cabinet be exhausted to the outside. NuAire offers a canopy type of exhaust transition, which will capture the exhaust
efflux from the cabinet.
Canopy, Thimble or Air Gap Exhaust Transitions
Note: The Exhaust System should be fitted with a backdraft damper to prevent reversing of airflow in the system.
NuAire only recommends a canopy or thimble transitions for exhausting applications. See separate instruction sheets for a
discussion of exhaust transitions and installation requirements.
5.2 Set-Up Instructions
Remove outer shipping protection (carton or crating). The cabinet is fastened to the base skid and it is usually the best
procedure to leave the skid in place until the cabinet is located in its approximate position to facilitate ease in handling. It
can then be removed from the skid by removing the banding, bolts and screws holding the cabinet to the skid. It may be
necessary to remove the control center in order to gain passage through a doorway. It can easily be removed by following
the instructions on drawing BCD-16301.
It is recommended that no less than two people are present using a lifting
system for placement of the cabinet onto the bench or base stand. It is not
recommended to manually lift the cabinet onto the bench or base stand.
