3.18.1 General

This manual gives basic instructions which are to be observed during installation of the pump. It
is therefore important that this manual is read by the responsible personnel prior to assembly and
afterward to be kept available at the installation site.
The instructions contain useful and important information allowing the pump/pump unit to be properly
installed. They also contain important information to prevent possible accidents and serious damage
prior to commissioning and during operation of the installation.
Non-compliance with the safety instructions may produce a risk to the personnel as well as to the
environment and the machine, and results in a loss of any right to claim damages.
It is imperative that signs affixed to the machine, e.g. arrow indicating the direction of rotation or
symbols indicating fluid connections isobserved and kept legible.

Sufficient room should be left around the pump/pump unit to allow proper inspection, pump isolation
and maintenance.
Sufficient space should be left in front of the pump to enable disassembly of the pump cover, idler
