Introduction Chapter Overview
This chapter provides a summary overview of knowledge required to understand the locations the
oven can be installed in; the hazardous material types it is engineered to work with or around;
operator competencies; the explosion-preventing protection technologies it employs; special repair
(service) and repair documentation requirements; utilities such as gas and vacuum as well as
consumables required to operate the oven.

IEC Ex-marked CVO-5-EX-SS vacuum ovens are designed to help prevent the ignition of potentially
explosive concentrations of gases or vapors in the workspace atmosphere surrounding the oven.
This helps safeguard against concentrations created by accidents such as solvent spills, evaporation
from solvent containers inadvertently left open, or the failure of a room ventilation system. The
ovens are not designed or certified for use in locations where explosive concentrations are
always or frequently present in the workspace atmosphere as a part of normal operations.
To help safeguard against igniting ambient explosive concentrations, the oven automatically purges
and over pressurizes internal enclosures containing its high-voltage electronic components,
including the heating elements. This purge and pressurize process is described in detail in this
manual and must be allowed to complete before the oven can be turned on. Additional safety
interlocks and features help to further protect against ignition.
The oven is engineered to help prevent the ignition of some hazardous gas and vapor types that
are regularly present and contained in the oven chamber and vacuum plumbing as a part of
standard operations. This includes solvent outgassing during extraction processes under vacuum
