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.
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.
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.
Shall the pump continue to suck beyond the automatic cut-out-level the float switch hast to be operated manually,
e.g. by holding it in upright position. To do this, you must remove the cable of the floating switch from the cable
guide (4) at the side. Then adjust the floating switch to the intended holder (13) underneath the cable guide by
sliding the switch vertically into the holder from above so that the cable pointes downside. Just in this operation
mode the min. suction level given in the technical data chart can be achieved. However, the pump must be
constantly monitored to avoid dry running.
5.5. How to position the pump
When positioning the pump, please make sure that the max. submersion depth indicated in the technical data will
not be exceeded. Likewise, please make sure that the minimum self-priming level is not fallen short of. If
everything is properly set, the water level may decrease down to the minimum suction level once the pump is
operating.
Please position the pump on solid ground. Avoid placing it on lose stones or sand. When positioning the pump,
please do make sure that the pump cannot tip over or sink into the ground with its intake openings (6). The
penetration of sand, mud or comparable matters is to be avoided.
To position, lift up or carry the pump, please use only the carrying handle. If required for lowering or raising the
pump, you may connect a suitable lowering rope to the carrying handle. In no case must the pressure hose, the
mains cable or the cable of the floating switch be used to position, to lift up or to carry the pump.
