4. Scope of delivery
The scope of the delivery of this product includes:
One pump with connection cable, one operating manual, 3 reducer pieces (measurements refer to chapter 5.2).
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.
Avoid excessive force when tightening the screwed connections, which can lead to 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 three reducer-pieces (10, 11, 12) providing the following
connection options: 1 x 47.80 mm (1 ½ ''), male, 1 x 41.91 mm (1 ¼ ") male, 1 x 33.25 mm (1 ") male.
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, c). To cut off these
superfluous parts we recommend the use of a commercially available saw. 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.
Also, it must be made sure that the floating switch can move freely.
In the manual operation mode the pump (with adjusted float switch) must be constantly
monitored to avoid dry running.
