The pump-motor unit may only
be put into operation when the
following conditions are met:
 Fan guard and vacuum
pump/compressor housing
are mounted.
 The lines to the discharge
connection, inlet connection
and operating-liquid port are
attached.
 The lines and connections
have been tested for strength
and leaks.

liquid!
8.1 Preparation
and start-up
CAUTION
If the pumped gases/vapors
discharged on the pressure side
are passed on,
then it must be ensured that the
maximum discharge pressure of
1.1 bar abs. [16.0 psia] is not
exceeded!
NOTICE
Maximum permissible quantity of
water entrained via the inlet
connection:
See Fig. 13, Pg. 32.
If a shut-off device is installed in the discharge
pipe:
Make sure that the unit CANNOT be operated
with the shut-off device closed.
Fill with operating liquid:
When and how the pump-motor unit must be
filled with operating liquid the first time is
dependent on the operating mode:
 For self-priming operation:
During installation.
 For operation with operating-liquid feed:
After completing installation.
For operation with operating-liquid feed,
you now fill the working area of the unit with
operating liquid.
To do this, open the respective stop valve for
approx. 20 sec.:
 For non-automatic operation:
Stop valve (Fig. 11, Pg. 32, Item 4).
 For automatic operation:
Stop valve in the bypass pipe (Fig. 12,
Pg. 32, Item 4a).
Then proceed with commissioning as
described in the following.
