•
Drill fastening holes for the pipe bracket on the in-
side of the shaft opening. If this is not possible, as
there is insufficient space, the pipe bracket may also
be fastened offset with an angle plate bent at 90° on
the underside of the shaft cover. Fasten pipe bracket
provisionally with 2 bolts.
•
Align the duck foot on the shaft floor, use plumb bob
from the pipe bracket, the guide pipes must stand
precisely vertically. Fasten duck foot with heavy duty
anchor bolts on the shaft floor. Ensure the duck foot
is precisely in a horizontal position. If the shaft floor is
uneven, support with an appropriate underlay.
•
Fit pressure line with fixtures according to the known
installation principles tension-free.
•
Plug both guide pipes into the eyes on the duck foot
and cut the pipe bracket to size according to position.
Unscrew pipe brackets, plug the pin into the guide
tubes and finally fasten the bracket. The guide pipes
must be seated absolutely backlash-free, as other-
wise loud noises will emerge when the pump is op-
erated.
•
Before commissioning, clean the shaft of solid ob-
jects (rubble, stones etc.).
•
Fit the coupling counter-flange of the automatic cou-
pling system on the pump pressure joint (threaded or
flanged connection). Ensure that the rubber profiled
seal (as a seal against the duck foot) is seated secure-
ly in the counter-flange, so that it cannot fall out when
the pump is lowered.
•
Fasten the chain to the pump carrying handle or car-
rying lugs. Guide the pump into the shaft with the
guide claw of the coupling counter-flange between
the guide tubes. Lower the pump into the shaft.
When the pump is resting on the duck foot, it seals
automatically to the pressure line and is operational.
•
Hang the outlet end on a hook in the shaft opening.
•
Hang the motor connection cable of the pump in the
shaft with a strain relief with a suitable length. Ensure
that the cable cannot be kinked or damaged.
If the pump's pressure side connection is frequently dry,
due to, for example, evaporation of the residual water in
the shaft, it is necessary to vent the pump housing per-
manently.
In order to ensure this, a 6 mm-wide hole can be bored
into the pump housing. The hole is bored into the pump
housing as shown in the sketch, opposite the pressure
side connection at a 45° angle.

Automatic Float Circuit
When the water level rises to a certain maximum level
(switch-on point) the floating float automatically switches
on the pump. If the water level drops to a certain mini-
mum level (switch-off point) by pumping down, the float
switches off the pump.
The switching gap, i.e. the difference in water level be-
tween the switch-on and switch-off point can be set in-
dividually.
For perfect functioning, please follow the instructions be-
low:
•
The fastening points and the length of the freely-mov-
ing end of the float cable are to be set to the desired
switching level. In so doing, it is to be noted that the
switch-on point of the pump is below the inflow pipe
to prevent the conveying medium from backing up.
The switch off point must be above the upper edge
of the pump housing, so that no air pockets can form
in the pump which may mean it is necessary to venti-
late the pump under the circumstances.
•
In no case must the float be simply thrown into
the conveying medium with a cable, as the correct
switching is only possible with a rotary movement
of the float around the fastening point of the cable.
Possible consequences of not following this are over-
flowing (pump does not switch on) or destruction of
the pump due to dry running (pump does not switch
off).
•
When using separate floats for starting the pump,
stopping the pump and alarm, the switching levels
are to be selected as above. The alarm float should
switch approximately 10 cm above the pump switch-
on point, but always below the supply.
•
Important: After the float fastening changes, the per-
fect functioning of the float circuit is to be checked
by a test run.
5.3. Use of chains
Chains are using for lowering and raising the pump in the
operating area. They are not using to safe pending pumps.
Use them as follows:
•
Fix one end of the chain on the handle of the pump.
•
Fix the other end of the chain on the lifting gear.
•
Tight the chain and lift the pump slowly.
•
Swing the pump over the operating area and lower it
carefully.
•
Make sure if the pump stands secure or if the cou-
pling system is connect tightly.
•
Remove the chain from the lifting gear and safe it on
the chain guard on the top of the operating area.
•
Make sure that the chain cannot fall down.
