Translation of the original operating manual
5.4.4 Aeration Valve
The rotational vacuum concentrator is equipped with an electro-
magnetic aeration valve. The rotor chamber is aerated through this
valve after the end of the evaporation process (manual and program
mode).
Unpressurised inert gas can also be used for aerating the rotor
chamber.
5.4.5 Option: Installation of the pressure control valve and the vacuum sensor
If a pressure control valve and a vacuum sensor are used, they must
be installed between the rotational vacuum concentrator and the
vacuum pump, and they must be connected to the marked IEC C14
connector at the rear side of the unit (see chapter 2.1, fig. 2.2).
Observe the installation direction of the pressure control valve! (see
fig. 5.3)!

5.4.6 Option: Aeration and Micro Injection Valve ("Valve Block")
As an option, the rotational vacuum concentrator can be equipped
with an electromagnetic aeration and injection valve.
In addition to the functions of the standard valve (see 5.4.4), this
valve can also inject air. If the vacuum value falls below the preset
value, this valve opens briefly to ensure a constant vacuum.
If the valve block is installed, the configuration of the control unit must
be adapted accordingly (see 6.3.5.5 "Options").
