7 Installation and electrical connection
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical
connections can result in a risk of fatal injury.
• The installation and electrical connections
should only be done by properly skilled staff and
in compliance with the applicable regulations!
• Follow all accident prevention regulations!
7.1 Installation
The pump is designed for stationary or transport-
able installation.
CAUTION! Danger of property damage!
Danger of damage due to incorrect handling.
Only suspend the pump by the strap with the aid
or a chain or rope, never by the electrical or float
switch cable or the pipe/hose connection.
The installation site or shaft for the pump must be
free of frost.
The shaft must be cleared of coarse material such
as rubble before setting up and starting the pump.
The quality of the shaft must guarantee the
unhindered mobility of the float switch.
Installation dimension / shaft dimensions
(cf. Fig 2)
The diameter of the pressure pipe (pipe/hose con-
nection) should not be smaller than the pressure
connection of the pipe because of the increased
risk of clogging and greater pressure losses. To
avoid pressure losses, it is recommended that the
pipe connection one number higher is selected.
Stationary wet sump installation
In the case of a stationary wet sump installation of
the pump with a permanent pressure pipe, the
pump must be positioned and secured so that:
• The pressure pipe connection does not support
the weight of the pump.
• The load of the pressure pipe does not act on the
connecting socket.
• The pump is installed stress-free.
To protect against any backflow from the public
drainage pipe, the pressure pipe must be taken in
an arc over the locally established backflow level
(usually street level). A non-return valve does not
represent a guaranteed backflow seal.
• The attached non-return valve should be installed
if the pump is installed permanently.
• Seal the pipe connections to the pressure port
with Teflon tape.
NOTE: Permanent leakage in this area can lead to
destruction of the non-return valve and of the
screwed connection.
Transportable wet sump installation
In the case of a transportable wet sump installa-
tion with hose connection, the pump must be
secured in the shaft to prevent it from falling over
and wandering (e.g. secure chain / rope with slight
pre-tension).
NOTE: When used in a sump without a firm base,
the pump must be put on a sufficiently large plate
or hung from a rope or a chain in a suitable posi-
tion.
7.2 Electrical connection
Danger! Risk of fatal injury!
If the electrical connection is not made properly,
there is a risk of fatal injury from an electric
shock.
Only allow the electrical connection to be made
by an electrician approved by the local electric-
ity supplier and in accordance with the local reg-
ulations in force.
• The type of mains connection current and voltage
must correspond to the details on the name plate
• Fuse in the power supply: 10 A, slow,
• Earth the installation according to the regulations.
• The installation of a leakage current protection
switch to be provided on site for a trip current of
30 mA is recommended (caution when installing
outside).
• The pump is ready to connect.
To connect the pump to the switchgear, the
shock-proof plug is disconnected and the con-
necting cable is then connected as follows (see
Installation and operating instructions for the
switchgear):
3-wire connection cable: 3x1.0
mm
²
Socket and switchgear must be installed in a dry
room and protected against flooding.
