NOTE
Note the switching level for the alarm signal if you
want to protect drainage fixtures that are on a lower
level!
See the installation and operating instructions for the switchgear
for precise information about the switch contact and the individu-
al work steps for connecting it.

5.4.5. Operation with frequency converters

Operation on a frequency converter is not possible.

Commissioning

The "Commissioning" section contains all the important instruc-
tions for operating personnel on commissioning and operating the
lifting unit safely.
It is essential for the following general conditions to be complied
with and checked:
• Operating mode
• Max. intake/h
• Max. suction head
These general conditions must also be checked after
a lengthy period without operation, and any defects
detected must be repaired!
Always keep this manual either by the lifting unit or in a place
specially reserved for it, where it is accessible for all operating
personnel at all times.
In order to prevent damage or serious injury when commissioning
the lifting unit, the following points must always be observed:
• Electrical engineering and mechanical settings as well as
commissioning of the lifting unit are only allowed to be
carried out by qualified and trained personnel in accord-
ance with the safety instructions.
• All persons working on or with the lifting unit must have
been provided with this manual and have read and under-
stood it.
• All safety devices and emergency cut-outs must be
connected and inspected to ensure that they are working
properly.
• The lifting unit is suitable for use under the specified oper-
ating conditions.
• Make sure a second person is present at all times when
you are working in the sump. If there is a risk of poisonous
gases building up, make sure that adequate ventilation is
provided.

Checking the installation/system

Commissioning may be carried out only if the installation is
complete, all relevant safety regulations (e.g. VDE regulations in
Germany) and regional regulations are met, and all the points have
been checked.
BEWARE of material damage!
If the installation and the following checks are not
carried out properly, the lifting unit may become
seriously damaged during operation. Check the
installation and carry out the following inspections.
6.1.1. Checking the installation
Check the installation to ensure all the necessary work was carried
out properly:
• Ground-fastening
• Mechanical connections
• Inlet with check valve
• Discharge pipe with check valve
• Venting via roof
• Electrical connection:
• Clockwise rotating field present.
• The lifting unit must be properly fused and grounded.
• Assembling the switchgear
• Connection of the mains-side power supply cable to the
switchgear
• Laying the power supply cables
• Assembling the external alarm signal (optional)
• Assembling the diaphragm hand pump for emergency
draining
• System completely cleaned, especially of solid matter.
6.1.2. Checking the system
Complete the following tasks before commissioning:
Position of the venting screw on the built-in non-return
valve
Fig. 9.: Position of the venting screw
The venting screw must be unscrewed by at least 25 mm to en-
sure secure system operation. Check the position of the venting
screw.
If the venting screw is screwed too far in, this can
lead to damage on the valve and unit, as well as to
high noise development.
Function test for level control
The level control device must be checked to ensure it is in a fault-
free mechanical state.
1. Open the maintenance cover.
2. Check that the float switch can move freely and has a firm
fit on the rod.
3. Seal up the inspection opening again.
6.2.

Operation

The lifting unit is operated via the fitted switchgear. The LEDs
on the front and the buttons on the side are used to execute and
indicate switching on/off, automatic mode and to display the
individual monitoring facilities.
The switchgear is preset for operating the system. The only
setting that needs to be made during initial commissioning is the
pump's follow-up time.
See the installation and operating instructions for
the fitted switchgear for all the necessary infor-
mation about operating the switchgear and the
individual displays.
6.3.

Rotation control

Rotation is controlled via the switchgear.
See the installation and operating instructions for
the fitted switchgear for all the necessary infor-
