Shutting down
Set the rocker switch to "0". This shuts
down the pump. The alarm system is
still ready for use.
Do not use position "0" of the
selector switch for repair and
maintenance work on the con-
trol unit and pump, but rather always
unplug them from the mains or turn
them off at the main switch.
Inspection
To maintain operational reliability, car-
ry out a visual inspection of the lifting
station, including the pipe connections,
once a month.
MAINTENANCE
We recommend that you service the
equipment in accordance with EN
12056-4.
To ensure continued reliability of ser-
vice, we recommend that you take out
a service contract.
Servicing and maintenance of
the sewage lifting station as
well as repair work must be
carried out by a qualified technician at
intervals of 3 months in industrial
plants or 6 months in blocks of flats.
Before carrying out any work,
unplug the lifting station from
the mains power supply or turn
it off at the main switch and ensure that
the power supply to the lifting station
cannot be switched on again by anyone
else.
Check the plug and the mains
cable for signs of mechanical
and chemical damage. Dam-
aged or kinked hoses must be replaced.
We recommend that the following work
is included in the service:
1. Check the connection points for wa-
tertightness by inspecting the areas
surrounding the lifting station and
the fittings.
2. Operate the sluice valves and check
that they move easily. Adjust and
grease them if necessary.
3. Open and clean the swing-type
check valve; check the seat and ball
(valve).
4. Clean the pump and the pipes where
they connect to the lifting station;
check the impeller and the bearings.
5. Oil check. If necessary top up or car-
ry out an oil change.
6. Clean the inside of the tank (as nec-
essary, or if especially required); re-
move any grease, for example.
7. Check the condition of the collecting
tank.
8. Flush the system through with water
once every 2 years.
9. Inspect the electrical section of the
lifting station. The control unit itself
is maintenance-free, but if a re-
chargeable battery is fitted, then it
should be checked regularly to en-
sure that it is in good working order.
To do so, unplug the lifting station
from the mains and lift the float of
the level controller slowly by hand
and hold it there until a high-water
alarm is triggered. In addition, clean
the float if necessary.
When all the maintenance tasks have
been performed, carry out a test run
and then put the lifting station back into
operation. The service must be docu-
mented, giving details of the important
data and of all the tasks carried out.
Oil check
First of all loosen the hexagon screws
or Allen screws around the pump and
lift the pump off the duckfoot bend. The
filling and draining port of the oil reser-
voir is sealed off with a screw-on drain
plug labelled "Oil". In order to check
the mechanical seal, the oil, including
any residue, must be drained from the
oil reservoir and collected in a clean
measuring container.
• If the oil is contaminated with water
(milky), an oil change must be carried
out. Check again after a further 300
operating hours, but at the very latest
after 6 months!
• However, if the oil is contaminated
with both water and pollutants, then not
only the oil must be replaced, but the
mechanical seal as well. For monitor-
ing the oil reservoir, it is also possible
to retrofit the electrode of our "DKG"
seal leak control device in place of the
"DKG" screw plug.
Oil change
To ensure operational reliability, the
first oil change should be carried out
after 300 operating hours, with further
oil changes carried out after every 1000
operating hours. If the number of oper-
ating hours is very low, an oil change
should still be carried out at least once
a year.
ENGLISH
If wastewater with strongly abra-
sive constituents is being pumped, oil
changes should be carried out at cor-
respondingly shorter intervals.
Use HLP hydraulic mineral oil, viscosity
class 22 to 46, e.g. Nuto from ESSO or
DTE 22, DTE 24, or DTE 25 from Mobil,
to replace the oil in the oil reservoir.
The quantity of oil required is 1000 cm³
for ...C1 pumps and 1700 cm³ for ...B5,
...B6 and ...C5 pumps.
The oil reservoir must be filled with the
specified quantity of oil only. Overfilling
will result in the pump being rendered
inoperable.
