COMMISSIONING/OPERATION English
Installation and operating instructions Wilo-EMUport CORE 45
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
allowed to be carried out only by qualified and
trained personnel in accordance with the safety
instructions.
• All persons working on or with the lifting unit
must have been provided with this manual and
have read and understood it.
• All safety devices and emergency cut-outs have
been connected to the switchgear that is to be
set up on-site and checked to ensure that they
work properly.
• The lifting unit is suitable for use under the speci-
fied operating conditions.
• When working in pump chambers, a second per-
son must be present. If there is a risk of toxic gas-
es forming, sufficient aeration must be ensured.
6.1. Commissioning
Commissioning may be carried out only if the
installation has been completed and all relevant
safety regulations (e.g. VDE regulations in Germa-
ny) as well as regional regulations are met.
BEWARE of property damage!
Commissioning must be carried out properly
prior to regular operation, because other-
wise the lifting unit could suffer considerable
damage during operation. Perform all of the
points properly.
6.1.1. Operation
The operation of the lifting unit takes place using
a switchgear to be set up on-site.
See the installation and operating instructions
for the switchgear for all the necessary infor-
mation about operating the switchgear and the
individual displays.
6.1.2. Rotation direction monitoring of the sewage
pumps
The sewage pumps must be connected clock-
wise for correct operation of the lifting unit. The
rotation direction monitoring must take place via
switchgear.
If the direction of rotation is incorrect, then
the sewage could be pumped in the collection
reservoir under certain circumstances, and this
could cause the tank to burst!
6.1.3. Checking the installation
Check the installation to ensure all the necessary
work was carried out properly:
• Fastening
• Floor fixation carried out properly
• Mechanical connections
• All of the connections are tight, no leakage
emerges
• Inlet with shut-off device
• Venting via roof
• Switchgear
• Corresponds to the minimum requirements
for the operation of a sewage lifting unit with
solids separation system
• Pumps and level control device are connected
in accordance with regulations.
• Switching points have been stored in the
switchgear
• Electrical connection:
• Clockwise rotating field present.
• The system is properly protected and earthed.
• Installation of switchgear and electrical con-
nections is overflow-proof
• Orderly placement of power supply cables
6.1.4. Checking the system
Complete the following tasks before commis-
sioning:
• Clean the system, in particular of sold materials
and readily flammable objects (e.g. cotton waste).
• Working area of the system is defined and marked
in a way that is both unambiguous and clearly
recognisable.
6.1.5. Initial commissioning
Before the lifting unit can be taken into operation,
it must be filled and a test run carried out. The
test run must include a complete pump cycle for
both pumps.
BEWARE of malfunctions!
Before switching on the switchgear, read the
installation and operating instructions and
ensure that you are familiar with the switch-
gear’s operation and displays.
1. Switching on the system via the switchgear: Main
switch to “ON”.
2. Check the switchgear’s operating mode. The
switchgear should be in automatic mode.
3. Open all of the shut-off devices so that the col-
lection reservoir slowly becomes filled:
• 1x Inlet pipe
• 2x Blocking of the solids separation reservoir
• 2x Discharge pipeline
• On-site shut-off devices in the pressure pipe if
necessary
4. The two sewage pumps must be switched on and
off in alteration via the level control device.
5. For a successful test run, both pumps must run
through a complete pumping procedure.
6. Close the gate valve in the inlet. In the normal
case, the lifting unit should now not switch on
again because no more fluid flows in.
If the lifting units should still switch back on
again, then the shut-off device in the inlet or a
non-return valve is leaking. Check the installa-
tion and consult Wilo customer service.
7. Check to ensure that all pipe joints and the col-
lection reservoir do not leak.
