Installation on concrete foundation
Foundation requirements
•
The concrete must have a compression resistance of C12/15 and meet the requirements of
exposure class XC1 according to EN 206-1
•
Sizes must be appropriate for the sizes of the unit support plate
•
The foundation weight must be ≥ 1.5 times the unit weight (≥ 5 times the weight of the unit
if a quieter operation is required)
•
The surface should be as flat and level as possible.
Installation
1.
Drill the tie rod holes in the number, with the diameters and centre distances shown in the
technical catalogue.
2.
Insert the tie rods into the holes and secure them with chemical anchors.
3.
Remove the caps of the suction and discharge ports.
4.
Place the unit on the foundation by inserting the tie rods into the holes in the plate.
5.
Level the unit with a spirit level on the shaft and discharge port: the maximum permitted
tolerance is 0.2 mm/m (0.0024 in/ft).
6.
Align the suction and discharge ports to their piping.
7.
If necessary, insert levelling shims between the plate and the foundation.
8.
Tighten the nuts on the tie rods evenly and fully.

DANGER: Explosion due to static charge
Ensure that the base plate is earthed correctly.
Reducing vibrations
The motor and the flow of liquid in the piping can generate vibrations, which may be amplified
from the possible incorrect installation of the unit and the piping. See
page 21.
