11. Interior Switched Duplex is located on the glove box ceiling. The
innermost outlet of the duplex labeled “AUX” is controlled by the switch
located on the front control panel. The other outlet is on constantly when
the glove box is connected to an electrical supply. An accessory Electrical
Power Strip can be connected to the outlet to provide more electrical
receptacles (see Chapter 7). The interior duplex is rated at 115V, 5A or
230V, 2A or 100V, 5A.
12. Transfer Chamber Doors have a molded one-piece neoprene gasket with
a quick operating latch for user convenience. The counterweighted doors
swing up to save space. IMPORTANT: The transfer chamber must
have an optional High Vacuum Sleeve if the chamber is converted for
vacuum operation on Precise Basic Glove Boxes. See Chapter 7.
13. Pressure Relief Valve provides a safety relief for over or under
pressurization events within the glove box main chamber. The valve is set
to relieve positive or negative pressures above +6 or below -6 inches of
water gauge. The designed operational maximum limits for the Precise
Glove Box is +/-5 inches of water gauge. See Chapters 2, 3, and 7 for
exhausting properly. The pressure relief valve is included on Precise
Controlled Atmosphere Glove Boxes and can be ordered from Chapter 7
for modification of the Precise Basic Glove Boxes. See Chapter 3 for
modification instructions adding a Pressure Relief Valve to the Precise
Basic Glove Box.
