3.18 Installation
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 after-
ward 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 result 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 be observed and kept legible.
Because of the presence of strong magnetic fields there are special safety instructions
which must be observed.
Personnel who carry a cardiac pacemaker should not be allowed to work on a pump equipped with
magnetic coupling! The magnetic field is sufficiently strong to affect the proper operation of a pace-
maker, so keep a safe distance of at least 3 m.
Do not come close (not less than 1 m) to the magnetic coupling with objects equipped with
magnetic data carriers such as cheque cards, computer disks, watches etc. to avoid damage and/or
loss of information.
Preservation: To prevent damage during transportation, the rotor bearing is blocked on the
drain hole of the pump casing with a protection plug. Remove this protection plug and place the plug
(1030) together with the sealing ring (1040) on the pump in plastic bag. Check that the pump shaft
can be rotated by hand. Keep the protection plug for subsequent transport, checks or repair work.
Do not subject the pump to any jolting loads. This can cause damage to the magnets or the slide
bearings of the rotor shaft on account of their brittleness.
