Work steps
1. Installation of the suspension unit: about 1-2 h
(please see the operating manual for the suspen-
sion unit).
2. Preparing the pump for operation on a suspension
unit: about <1 h (please see the installation and
operating instructions for the suspension unit).
3. Installing the pump: about 1-2 h
• Check that the suspension unit is firmly fixed
and functions properly.
• Secure the lifting equipment to the pump with
the shackle, lift the pump and then lower slowly
on to the guide pipes in the operating space.
• Hold the power supply cables slightly taut
when lowering.
• When the pump is connected to the suspension
unit, make sure that the power supply cables
are secured adequately against falling off and
damage.
• Have the electrical connections made by a
qualified electrician.
• The pressure connection is sealed by its own
weight.
4. Installing optional accessories, such as dry-run-
ning protection or level controls.
5. Starting up the pump: about 1 h
• As described in the 'Commissioning' section
• For new installation: Flood the operating space
• Vent the pressure pipe.
5.3.5. Portable wet well installation
In this installation type, the pump has to be
equipped with a pump support foot (available as
an option). This is attached to the suction port
and ensures the minimum ground clearance and
a secure footing if placed on a solid bearing sur-
face. In this version, the pump can be positioned
anywhere in the operating space. If used in an op-
erating space with a soft bearing surface, a hard
base must be used to prevent sinking. A pressure
hose is connected on the pressure side.
If operated for longer periods of time in this in-
stallation type, the pump must be fastened to the

floor. This prevents vibration and ensures quiet
and low-wearing running.
If the motor should be operated non-immersed,
the following specifications must be strictly
observed:
• Maximum ambient temperature
• Maximum fluid temperature
• Details for 'Non-immersed operating mode'
The ambient temperature is equivalent to
the fluid temperature. For the maximum fluid
temperature, refer to the rating plate or the
separate data sheet.
BEWARE of burns!
The housing parts can heat up to well above
40°C. There is a risk of burns! After switch-
ing it off, let the pump cool down to ambient
temperature.

Work steps
1. Preparing pumps: about 1 h
• Install the pump support foot on the suction
connection.
• Install the pipe elbow on the pressure connec-
tion.
• Fasten the pressure hose to the pipe elbow
with a hose clip.
Alternatively, a Storz pipe coupling can be
installed on the pipe elbow and a Storz hose
coupling can be installed on the pressure hose.
2. Installing the pump: about 1-2 h
• Position pump in installation location. If neces-
sary, secure lifting equipment to the pump with
a shackle, lift the pump and then lower to the
intended location (pump chamber, pit).
• Check that the pump is vertical and on a solid
bearing surface. Avoid sinking.
• Route the power supply cable so it cannot be
damaged.
• Have the electrical connections made by a
qualified electrician.
• Route the pressure hose so that it is not
damaged and fasten it at certain points (e.g.
outflow).
