6.4.3 Connection of an extraction system at the pump module

Avoid the solvent accumulation in the pump module as this would cause the pump module to
become an occasionally or continuously / for long periods / frequently potentially explosive
area (Zone 0 or 1). The VDL vacuum drying oven located on top of the module is constructed
in device category 3 in regards to its surroundings.
Explosion hazard due to the spread of an explosive atmosphere to unprotected
chamber parts and ignition due to electric sparking or hot surfaces
Serious injury or death from burns and / or explosion pressure.
 Provide active extraction (technical ventilation according to country-specific regulations
– TRBS 2152 Part 2 for Germany) prior to commissioning the chamber.
 Extraction must include the entire installation area of the vacuum drying oven and pump
module.
 Connect an extraction system to the provided port on the rear of the pump module.
6.5

Vacuum connection

Connect the vacuum drying oven to a vacuum pumpor to a domestic vacuum system. For this purpose,
the vacuum connection (6) with small flange DN16 must be connected to the back of the chamber at the
top with the vacuum pump or domestic vacuum system via a vacuum suction hose or a fixed vacuum
pipe.

When using a vacuum suction hose BINDER recommends the connection kit for the VP4 pump from
BINDER (chap. 6.5.5). The optional pump module (chap.) provides an appropriate hose port on the rear.
