Conditions for setting up the system:
The unit should be set up:
 on a level surface with a load-bearing capabil-
ity suitable for the weight of the unit,
 with the shaft in a horizontal position,
 on stationary (fixed) surfaces or structures,
 with a clearance from adjacent surfaces in
accordance with the table, "Minimum clear-
ances for heat dissipation", page 8
 at a maximum height of 1000 m [3280 ft]
above sea level.
If the conditions for setting up the unit deviate
from the above please contact the service de-
partment.
When setting up, take due account of vibration
characteristics at the location. The unit's overall
vibration will depend on:
- the unit's own vibration,
- the alignment and positioning,
- the condition (vibration characteristics) of
the supporting surface,
- The effects resulting from oscillations in o-
ther components and parts of the plant (ex-
ternal oscillations).
The maximum permissible value for oscilla-
tions is v
eff
= 4.5 mm/s [0.177"/s].
The measuring points for determining the os-
cillating speed are shown in Fig. 7, page 15.

Securing the unit:
 the unit's mounting feet (item 2, page 3) are to
be bolted to the base using suitable fixings.
Fit bolts in all fixing holes!
The types 2BV5 110-….2-.S and
2BV5 121-….2-.S are supplied with intermediate
plates for height adjustment.
 The intermediate plates (item 3, page 3) are
to be inserted under the mounting feet on the
pump casing before securing.
 The unit's mounting feet (item 2,, page 3) are
to be bolted to the base using suitable fixings.
Fit bolts in all fixing holes!
5.2 Mechanical connection of the unit
The unit is supplied with all connection openings
sealed off to prevent the ingress of foreign mat-
ter.
 Only remove the seals immediately before
connecting up the piping / hoses.
The gases /vapours are drawn in through the
inlet connection (item 8, page 3) and expelled
through the discharge connection (item 7,
page 3).
The unit has to be continuously supplied with
operating-liquid during operation.
This supply is introduced via the operating-liquid
connection (item 6, page 3) and is expelled to-
gether with the gases / vapours via the discharge
connection.
Filling up with operating-liquid:
The initial charge of operating-liquid is dependent
on the type of operating-liquid supply:
 When operating with self-suction of the oper-
ating-liquid:
before installation, see description below.
 When operating with supply of the operating-
liquid:
after completion of installation, see "Filling up
with operating-liquid", page 20.
For operation with self-suction of the operating-
liquid, fill the unit's operating chamber with oper-
ating-liquid before the piping / hoses are installed
on the unit.
 Fill up with operating-liquid through the open
inlet connection or discharge connection in
accordance with the table, "Quantity of operat-
ing-liquid for first fill, page 12.
