15.2 Vacuum module empty (without pump) (option)

how to mount the VDL vacuum drying oven onto the vacuum module and installing the

Connection to a vacuum source
Connect the vacuum connection (13) (small flange DN 16) at the
rear of the unit at the top to a vacuum pump or to a domestic
vacuum system via a vacuum hose or a fixed vacuum pipe.
When using a vacuum hose, we recommend using the BINDER
connection kits for VP4 or VP5 (chap. 15.1). The module has an
appropriate hose outlet at the back.

The end vacuum must NOT fall below the permissible level of 10 -2 mbar / 0.0003 inHg.
 Install the pump according to the permissible end vacuum or limit the end vacuum via a
vacuum controller.
Avoid the solvent accumulation in the vacuum module (option) as this would cause the vacuum
module to become an explosive area (Zone 0 or 1 or 2). The VDL vacuum drying oven located
on top of the module is not explosion-proof constructed in regards to its surroundings.
