Working steps
1. Installation of the suspension device: about 3-6 h
(please see the operating manual for the suspension
device).
2. Preparing the pump for operation on a suspension device:
about 1-3 h
(please see the operating manual for the suspension
device).
3. Installing the pump: about 3-5 h
• Check that the suspension device is firmly fixed and
functions properly.
• Secure the hoisting gear to the pump with the shack-
le, lift the pump and then lower slowly on to the guide
pipes in the operating area.
• Hold the electric power cables slightly taut when low-
ering.
• When the pump is connected to the suspension device,
make sure that the electric power cables are secured
adequately against falling off and damage.
• Have the electrical connections carried out by a qualified
electrician.
• The discharge port is sealed by its own weight.
4. Installing optional accessories, such as dry-run protection
or level controllers.
5. Starting up the pump: about 2-4 h
• As described in the "Start-up" section
• For new installation: Flood the operating area
• Bleed the discharge pipe.
5.4.2. Portable wet installation
With this installation type, the product must be equipped with a
pedestal (available as an optional extra). It is fitted to the intake
port and ensures the minimum floor clearance and a secure po-
sition on a firm foundation. This installation type makes optional
positioning in the operating area possible. For use on a soft foun-
dation, a hard base must be used to prevent the machine from
subsiding.
A discharge hose is connected on the discharge side.
The unit must be anchored to the floor for longer operating times
with this type of installation. This prevents vibrations as well as
guaranteeing quiet and low-wearing running.
BEWARE of burns!
The housing components can heat up to well above
40°C. there is a danger of burns! After switching
off, let the product cool down to ambient tempera-
ture.

Working steps
1. Preparing the pump: about 1 h
• Mount the pedestal at the intake port.
• Attach the pipe bend to the discharge port.
• Fix the discharge hose to the pipe bend with the hose
clamp.
Alternatively, a Storz fixed coupling can be fitted to the
pipe bend and a Storz hose coupling to the discharge
hose.
2. Installing the pump: about 1-2 h
• Position the pump at the place of use. If necessary,
secure the lifting gear to the pump with shackles, lift
the pump and set it down at the intended operating
position (pit, shaft).
• Check that the pump is upright and standing on a firm
base. Do not let it subside!
• Lay the power supply cable so that it cannot be dam-
aged.
• Have the electrical connections carried out by a qualified
electrician.
• Lay the discharge hose so that it cannot be damaged
and secure at a suitable place (e.g. drain).
BEWARE of the discharge hose being pulled off!
Injuries may result from the discharge hose being
pulled or knocked off accidentally. The discharge
hose must be secured appropriately. Avoid kinks in
the discharge hose.
3. Starting up the pump: about 1-3 h
• As described in the "Start-up" section

5.4.3. Level control

Fill levels can be determined using the level control system, mean-
ing the unit is switched on and off automatically. The fill level
can be recorded using float switches, pressure and ultrasound
measurements or electrodes.
Note the following information:
• When using float switches, ensure that they can move
freely in the operating area.
• The water level must not fall below the minimum.
• The maximum starts per hour may not be exceeded.
• If the fill levels fluctuate strongly, then a level control
should be made on two test points as standard. This
means larger differential gaps are reached.
Installation
The A version in the lix series is fitted with a float switch for
recording the level. A contact is opened or closed here, depending
on the angle of inclination on the float switch.
