The diameter of the pressure pipe (pipe/hose
connection) 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 recommend-
ed that the pipe connection one number higher is
selected.
7.1.1 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.
7.1.2 Transportable wet sump installation
In the case of a transportable wet sump instal-
lation 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 position.

7.2 Electrical connection

DANGER! Risk of fatal injury!
If the electrical connection is not made proper-
h1±8 h2±8
ly, there is a risk of fatal injury from an electric
shock.
Only allow the electrical connection to be
140 24
made by an electrician approved by the local
electricity supplier and in accordance with the
140 24
local regulations in force.
• The type of mains connection current and voltage
must correspond to the details on the name plate
d
• Fuse in the power supply: 10 A, slow,
• Earth the installation according to the regula-
tions.
161
• The installation of a leakage current protection
switch to be provided on site for a trip current of
171 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 mm².
Brown:
Blue:
green/yellow:
Socket and switchgear must be installed in a dry
room and protected against flooding.
8. Commissioning
DANGER! Danger through electric shock!
The pump may not be used to drain swimming
pools / garden ponds or similar place if anyone
is in the water.
CAUTION! Danger of property damage!
Do not allow the mechanical seal to run dry!
Dry running shortens the service life of the
motor and the mechanical seal. If the mechan-
ical seal is damaged, small amounts of oil may
escape into the pumped fluid.
• When filling the shaft or lowering the pump into
the pit, make sure that the float switches can
move freely. The switch must switch off the pump
before the intake openings of the pump can draw
in air.
• After filling the shaft and opening the check valve
on the pressure side (if provided), the pump starts
up automatically when the switch-on level ‚h' is
reached and switches off as soon as the switchoff
level ‚h1' responds.
• Do not point the water jet entering the shaft at
the pump strainer. Entrained air can prevent the
pumping of the pump when it is starting up.
• The maximum volume of water entering the shaft
must not exceed the performance of the pump.
Keep an eye on the shaft when commissioning
the pump.
