4. Scope of delivery
The scope of the delivery of this product includes:
One pump with connection cable, one connection port, one operating manual.
Please verify that the scope of delivery is complete. Depending on the purpose of the application,
additional accessories may be necessary (please refer to the chapters titled "Installation" and "How to
order spare parts").
If possible, keep the packing until the warranty period has expired. Please dispose of the packing
materials in an environmental-friendly manner.
5. Installation
5.1.
General installation information
During the entire process of installation, the device must not be connected to the
electrical mains.
The pump and the entire connection system have to be protected from frost.
All connection lines have to be perfectly tight since leaking lines may affect the performance of the
pump and cause considerable damage. If required, please use a suitable sealant to make the
installation airtight.
When tightening threaded connections, please do not apply excessive force which may cause
damage.
When laying the connection pipes, you should make sure that the pump is not exposed to any form of
weight, vibration or tension. Moreover, the connection lines must not contain any kinks or an adverse
slope.
Please observe the illustrations, too, which are contained as an attachment at the end of the present
operating instructions. The numeric and other details included in brackets below refer to these
illustrations.
5.2.
Installation of the pressure line
The pressure line conveys the liquids to be discharged from the pump to the point of withdrawal. To
avoid dynamic flow losses, one should use a pressure line having at least the same diameter as the
pressure port (1) of the pump.
The pressure line to be used for this type of application is an appropriate flexible hose - for instance, a
specially designed drainage hose.
To facilitate installation, the scope of delivery includes a two-piece multi-dimensional connecting bend
(10) providing the following connection options: ½ threaded male port for 33,25 mm (1 ") and
26,44 mm (¾ "), hose connector for 28 mm and 34 mm.
When adapting the connection to the pressure line, please remove the narrower and thus
unnecessary parts of the multi-dimensional connection piece at the cutting points provided for this
purpose (a, b). To cut off these superfluous parts we recommend the use of a commercially available
saw. When connecting to the male thread with 33.25 mm (1 "), only the bend of the reduction piece is
needed.
If this adaptation process is necessary, please perform it prior to connecting the multi-dimensional
connection piece to the pressure port of the pump.
5.3.
Stationary installation
If the unit is used in a stationary installation, rigid pipes have proven to be the ideal choice for the
pressure lines. In this type of installation, we recommend that you incorporate a check valve (non-
return valve) in the pressure line immediately following the pump outlet so that no liquid will flow back
after the pump cuts out. To facilitate maintenance work, we also recommend the installation of a stop
cock valve downstream of the pump and check valve. This arrangement is beneficial in that closing
the stop cock will prevent the pressure line from running dry after the disassembly of the pump.
5.4.
How to set the floating switch
Please make sure that the pump will cut out as soon as the water level decreases
and the floating switch has reached the cut-out level.
