CHAPTER 6: INSTALLATION REQUIREMENTS
6.1 Location
The room in which the glovebox will be used should be dry and well ventilated with a
temperature between 59°F and 86°F (15°C to 30°C). The floor should be level and stable
enough to support the weight of the glovebox system.
Position the glovebox in an area that allows the user to have adequate working space in and
around the system (e.g. gloveports, antechamber(s), etc.). If positioned against or near a wall,
the clearance should be a minimum of approximately 24 inches (600 mm) for the rear and side
of the glovebox without antechamber(s).
6.2 Gas Supply and Connection Requirements

operating gas for electropneumatic valves.
Gas Type:
Nitrogen, Argon, Helium supplied at 80psi.
Purity:
Industrial grade or better; from tanks or other facility gas supply source.
Quantity:
Permanent supply for the system’s operation (e.g. pressure compensation,
etc.).
