4. Scope of delivery
The scope of the delivery of this product includes:
One pump with connection cable, an outlet element, 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 the pump is to be used for example as rain barrel pump, corresponding accessories can be ordered
in our spare parts shop.
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.
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.
To facilitate installation, a quick coupling connector for direct connection of a garden hose is included.
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.
The pump is equipped with a floating switch (2) causing the unit to cut in or out automatically as a
function of the water level as soon as the water level has reached, or dropped below, the cut-out level,
the pump will cut out. When the water level reaches or raises above the cut-in level, the pump will
resume operation. The cut-in and cut-out levels can be adjusted by shortening or lengthening the
freely movable cable (3) of the floating switch. The length of the cable can be set at the cable duct (4)
located at the carrying handle (5) of the pump. In this regard, the relevant part is the freely movable
part of the cable leading from the cable duct to the floating switch. If this length increases, the cut-out
level will decrease, and the cut-in level will augment. Vice versa, if its length decreases, the cut-in
level will increase whereas the cut-out level will be lowered.
