steam can damage them.
The sterilizer must operate in absence of explosive atmospheres.
The sterilizer must operate in a well ventilated room far from
sources of heat and from flammable materials.
Place the sterilizer on a flat and level surface.
Clearance requirements to ensure proper air circulation:
