spheric pressure. Ambient air can be contaminated with helium due to
spraying or
charging. In this case a gas supply line (i. e. nitrogen, fresh air, …) should be con-
nected to the hose coupling Fig. 9/3. The pressure of these gas line must not
exceed 1050 mbar.
The connectors 1,2 and 3 in Fig. 9 are quick connectors for hose diameters of 8/
6 mm.
Connection of an external pump (only PHOENIX L300i MODUL)
The PHOENIX L300i MODUL
offers two possibilities to connect the external fore
vacuum pump to the DN 25 KF flange. One on the side of the PHOENIX L300i or
one in the bottom (measurements see Fig. 5 - Fig. 7). As default setting the flange
on the side is chosen. To change the connection proceed as follows:
1. Take of the mechanical hood, see chapter 4.4.1.
2. Loose the flange with the connection piece on the side of the PHOENIX L300i.
3. Disconnect the blind flange on the bottom, therefore lay the PHOENIX L300i
carefully on the electronic hood.
4. Screw in the connection piece into the flange in the bottom.
5. Connect the hose for the fore vacuum pump.
6. Connect the blind flange to the sidewise flange.
7. Put on the mechanical hood.
