5.2.5 Plumbing Services
Service ball valves with the type of service specified by the removable button on the handle are located in the
work zone. The service ball valves are not recommended for pressure over 75 p.s.i. (5.2 BAR). Reducing valves
should be installed external to the cabinet if necessary. Service ball valves should never be used for flammable
gasses or oxygen service. A special needle valve for oxygen service or certified valve is required and available upon
request.
External connection is to 3/8 inch NPT coupling in the inner sidewalls. Connection to plant utilities should be made
with proper materials for the individual service and according to national and/or local codes. Observe all labels
pertaining to the type of service and operating pressure.
5.2.6 Electrical Services
The NU-581 series Biosafety Cabinets may be "hardwired" (optional) or plugged into an outlet with
protective earthing connection with the standard power cord. The cabinet requires 115 VAC, 60 Hz, single phase
(current rating varies per cabinet size, reference Electrical/Environmental Requirements). It is recommended that
power to the cabinet, whether hardwired or plug connected, be on its own branch circuit, protected with a circuit
breaker at the distribution panel near the cabinet. A surge protector is strongly recommended if you are
experiencing power related faults.
NOTE: THIS CABINET CONTAINS ELECTRONIC BALLASTS FOR THE LED LIGHTING. ELECTRONIC BALLASTS
OPERATE WITH HIGH INRUSH CURRENT. IT IS NOT RECOMMENDED TO USE THIS PRODUCT WITH
GROUND FAULT CIRCUIT INTERRUPTERS (GFCI’S) BECAUSE THE BALLASTS MAY CAUSE THE GFCI TO
TRIP.
