Final Connections and Tests
1. The plumbing connection to the service petcocks must be made with great care because the affluent from a
safety cabinet may be biologically hazardous. When present, petcocks are piped within the cabinet. The
external connection uses 3/8” compression fitting at the rear, top, or bottom of the cabinet outer sidewall seal
panel. Qualified personnel with proper materials and technique should make connection to plant utilities per
NFPA. Flammable gas should not be piped into any cabinet. However, if the risk is professionally evaluated
and a decision is made to install a flammable gas petcock, then an emergency shut-off valve should be
situated in an accessible location outside the cabinet.
2. A 20 amp power cord with a NEMA 5-20P plug is furnished with the cabinet. It should be plugged into a
115V AC, 60 Hz, 20 amp dedicated utility outlet.
3. Thoroughly clean the interior of the cabinet. Locate the viewscreen at the correct opening height (8”or 10”
[203.2 or 254mm]).
4. Turn on the Blower. The indicator light will illuminate and the running blower will make an audible sound.
5. Turn on the Fluorescent Light. The indicator light will illuminate along with the interior work area.
(NOTE: The Fluorescent Light will not come on unless the blower switch is on. The Fluorescent Light
and UV Light are interlocked so they cannot operate simultaneously.)
6. If your cabinet has been purchased with the optional Ultraviolet Light (UV), lower the viewscreen to its fully
closed position and turn the UV light on to make sure it is operational. (NOTE: The UV light option
features an interlock that prohibits its operation unless the viewscreen is fully closed. The Fluorescent
Light and UV Light are interlocked so they cannot operate simultaneously.)
7. Although all units are carefully tested at the factory, it is advisable that certain other checks are made on-site
by a qualified technician after installation. These include testing the filters for leaks and checking the air
balance of the cabinet, especially if it is connected to an exhaust system. A description of these tests can be
found in Section 4, “On-site Checks and Maintenance”.
8. It is recommended that all personnel who will be using the cabinet study this manual to learn how to use it
effectively. For additional start up and use procedures, reference Section III, Proper Cabinet Use
