Otherwise you may not carry out any work with
or on the system!
 WARNING
Danger from vacuum!
Danger due to escaping fluid!
Danger due to rotating parts!
The system may only be put into operation
when the following conditions are met:
 The hoses on the inlet and discharge
connection and on the operating liquid
connection of the installed unit are
connected.
 The cover plate and the water cooler of the
separator are fitted.
 The lines and connection elements of the
operating liquid circuit are fitted.
 The line on the system inlet connection is
connected.
 The pipe/hose connections, pipes/hoses
and vessels have been checked for
sufficient strength and freedom from leaks!
 The fasteners have been checked for
secure seating.
CAUTION
If the installed unit is run dry, the mechanical
seal will be destroyed in a matter of seconds!
DO NOT switch on until the following
conditions are met:
 The separator must be correctly filled with
operating liquid.
 The interior of the installed unit must be
filled with operating liquid.
NOTE
For the system design, see Fig. 1, Pg. 3. The
item numbers (Item) specified in the text refer
to this illustration.
6.1 Preparation and start-up
Proceed as follows:
 Make sure that the following conditions are
met:
– The separator must be correctly filled with
operating liquid. (watch fill level indicator).
– The interior of the installed unit must be
filled with operating liquid.
– The separator cover plate must be
mounted.
 Turn power ON.
 The system begins to intake the pumped
gases/vapours.
NOTE
If, on being put into service for the first time,
the system does not generate a vacuum:
briefly throttle or close and reopen the inlet
side.
6.2 Shut-down
Generally speaking, the system may be shut
down in any operating condition (i.e. regardless
of the actual pressure, temperature, etc.).
Take into consideration, however, whether the
process of your line allows for interrupting the
operation of the system.
Proceed as follows:
 Turn power OFF.
 The system interrupts the intake of the
pumped gases/vapours.
In case the unit is not to be put into service again
for an extended period of time:
observe the instructions in Chapter 8, "Shutting
Down and Longer Standstill", Pg. 23.
