6 INSTALLATION AND COMMISSIONING
6.1 GENERAL REQUIREMENTS
The installation site of the pump should be dry and protected from splash water.
We recommend installing the pump in such a way that maintenance work can be carried out easily. Depending on
the type of variant or accessories fitted, additional free space may be required for this.
When assembling components and assemblies, the following points must be observed to avoid injury and damage to
the pump:
• Third-party components may only be installed if they have been
approved by the manufacturer and comply with the directives and
laws applicable in the country of use.
• Loose and non-pump parts must be removed from the pump
environment after assembly.
• Protruding parts (pipes, cables, etc.) must be properly mounted,
routed and marked.
• Contact points of components must be clean and intact.
Outside the permitted operating parameters, safe operation of the pump can no longer be guaranteed (for
permitted operating parameters, see chapter 9.2).
The minimum distances between the pump and neighbouring parts must be at least 10 cm. Failure to
maintain the minimum clearances may result in a fire risk due to the high level of heat emitted.
Fastening to the substrate
The pump can be installed on solid ground without anchoring. If the pump is to be installed on a
substructure, it is recommended that it be fastened using elastic buffer elements.
6.2 PREPARATORY ACTIVITIES
6.2.1 CONNECTING THE MEDIA LINE
Remove sealing plug
For transport, the suction connection is protected against the ingress of
dirt and foreign bodies with a sealing plug. This must be removed before
commissioning.
