5. Installation and initial commissioning
5.1. General
To avoid damage to the lifting unit during installation and
operation, the following points must be observed:
•
The installation work must be performed by qualified
personnel, in compliance with safety regulations.
•
The pump must be inspected for damage prior to in-
stallation.
•
For level controls, pay attention to the
minimum water coverage.
•
Air bubbles in the pump housing and pipework must
be avoided (by suitable ventilation devices or a slight
incline of the pump).
•
Protect the pump from frost.
•
The operating room must be designed for the partic-
ular machine. This also means that a lifting device for
assembly/disassembly can be mounted, from which
the installation space of the pump can be reached
without risk.
•
The lifting device must have a maximum load capaci-
ty which is greater than the weight of the pump with
attachments and cable.
•
The power lines of the pump must be laid in such a
way, that a safe operation and easy assembly/disas-
sembly is ensured.
•
The power lines must be fixed properly in
the operating room to prevent the cable from
hanging loosely. Depending on the cable length and
weight, a cable holder must be attached every 2-3 m.
•
The foundation/structure must have suf-
ficient strength for secure and functional
ly correct fastening of the pump. The operator is re-
sponsible for this.
•
A dry run is strictly prohibited. We recommend a level
control for that.
•
Use baffles for the inlet. This prevents air en-
try into the pumping medium, which can lead to
unfavorable operating conditions and result in
increased wear.
No.

5.2. Installation
Risk of falling!
When installing the pump and accessories, work is
carried out directly on the water‘s edge! Careless-
ness or wearing the wrong shoes can lead to falling.
This is life threatening! Take all safety precautions to
prevent this.
Submerged installation on ground support ring
Attach the ground support ring (available as an accesso-
ry) with screws to the pump suction nozzle. 90° connec-
tion-elbow or connection loop to the pressure port of the
pump, mount pressure line. Gate valves and check valves
may need to be installed in accordance with local regu-
lations. The pressure line must be fitted free of tension,
when using a hose, ensure it is laid kink-free.
Secure the pump by the handle with a cable or chain, and
lower it into the pumping medium. In muddy ground, put
stones under the pump to prevent it from sinking.
Wet installation with automatic coupling system
The following instructions apply to the installation of the
original HOMA-coupling system:
•
Determine the approximate position of the coupling
base and the upper pipe bracket for the guide tubes,
using a plumb bob where necessary.
•
Check the correct installation dimensions of the
pump(s) (see dimensional drawings in the appendix).
