NOTICE
Destruction of the pump due to gases with excessively high molecule masses
When conveying gases with non-permissibly high molecule masses, there is a risk of the turbopump
being destroyed.
► Make sure the gas mode is set correctly
[P:027]
on the electronic drive unit.
► Consult Pfeiffer Vacuum before using gases with larger molecule gases (> 80).
Notes on commissioning the turbo pumping station
1. Release the transport retainer.
2. When using water cooling, note the cooling water feed and flow.
3. When using sealing gas, note the sealing gas feed and flow.
6.2 Switching on the turbo pumping station
Switch on the power supply
► Switch on the power supply at the main switch.
The DCU carries out a self-test and a check of the connected units after switch-on. The duration of the
self-test is approx. 20 seconds and is visualized on the display with a progress bar.
Put the pumping station into operation
►
Switch on the turbo pumping station.
6.3 Operating mode of the turbo pumping station
Using the DCU
1. When using the Pfeiffer Vacuum DCU 002 display and control unit, observe the corresponding op-
erating manual supplied.

6.4 Operation with gas ballast
Steam or moisture from pumped media can condense in the backing pump and hence impair the suc-
tion performance. Adding gas ballast can improve the expulsion of condensate. The pumping station
reaches the specified final vacuum in a shorter time again.
● The backing pumps MVP 015-4 and MVP 030-3 have an adequately high water vapor tolerance
and are not fitted with a gas ballast valve.
● The MVP 015-2 backing pump is equipped with an electronic gas ballast valve.
