5 Set-up and connection
For pumps/aggregates in potentially explosive areas
(
ATEX additional instructions)
CAUTION
Risk of material damage caused by contamination!
►
Do not remove transport locks until immediately before
setting up the pump/aggregate.
►
Do not remove covers, transport and sealing caps until
immediately before connection of the pipes to the
pump/aggregate.
5.1 Preparing
set-up
5.1.1
Checking ambient conditions
►
Make sure the required ambient conditions are maintained
(
Ambient conditions, page 41).
►
For pump/aggregate set-up at an altitude of > 1000 m
above sea level, consult the manufacturer.
5.1.2
Minimum clearances for heat dissipation
Minimum clearances (
Clearances for heat dissipation,
page 41).
5.1.3
Preparing installation site
►
Make sure the installation site meets the following condi-
tions:
the pump/aggregate is freely accessible from all sides
sufficient space for installing/disassembling the pipes
as well as for maintenance and repair works, particu-
larly for installation/disassembly of the pump/aggregate
and the motor, is provided for.
the pump/aggregate is not exposed to external vibra-
tions (bearing damage)
frost
protection
5.1.4
Preparing foundation and surface
Set-up options:
with concrete foundation
with steel foundation frame
without
foundation
►
Make sure foundation and surface meet the following condi-
tions:
level
clean (free of oil, dust or other contaminations)
load carrying capacity is in accordance with the dead
weight of the aggregate and all operating forces
adequate aggregate stability
with concrete foundation: standard concrete of strength
class B 25
5.1.5
Removing preserving agent
►
If the pump/aggregate is commissioned directly after set-up
and connection: remove preserving agent prior to set-up (
Removing preserving agent, page 13).
5.2 Set-up
with
foundation
Only possible with base plate.
CAUTION
Risk of material damage caused by distortion of the base
plate!
►
Position and fix the base plate on the foundation as follows.
5.2.1
Placing aggregate on foundation
Auxiliary means, tools, material:
foundation bolts (
Set-up drawing)
steel
washers
non-shrinking mortar grout
spirit
level
1. Lift the aggregate (
Transport, page 11).
2. Hook the foundation bolts from below into the base plate
fixing holes.
Observe the manufacturer's specifications when using
adhesive anchors.
3. Place the aggregate on the foundation.
Insert the foundation bolts into the provided anchoring
holes.

Set-up with foundation
4.
Use steel washers to align the aggregate to height and
system dimensions as follows:
Place 1 steel washer (2) at the left and right hand side
of each foundation bolt (1).
With > 750 mm clearances between the anchoring
holes, an additional steel washer (3) must be posi-
tioned in the middle of each side of the base plate.
5. Make sure the steel washers are in surface contact with the
base plate.
6. Use the integrated spirit level to check whether the aggre-
gate is level end to end and side to side with a maximum al-
lowable tilt of 1 mm/m.
7. Repeat this process until the base plate has been correctly
aligned.
5.2.2 Fixing
aggregate
Filling the base plate with mortar grout improves the damp-
ening behaviour.
1.
Fill the anchoring holes with mortar grout.
2.
When the mortar grout has set, bolt down the base plate
with the specified torque at three points (
Tightening
torques, page 42).
3.
Before tightening the remaining bolts, compensate for any
unevenness in the surface using metal spacing shims next
to each bolt.
4.
Make sure the base plate is not distorted.
