6. Installation

The operator has to prevent damage through the
flooding of rooms caused by defects of the pump through
the use of appropriate measures (e.g. installation of alarm
units, backup pump or like that).
Fasten the tank to an even floor with expansion bolts.
Before installing the disposal units make sure that the all
national instrucions and the general measures for health
protection and industrial protection for the installation of
disposal units (DIN 1986) are observed. Furthermore
please pay attention to the hints below:

Install the unit in that way, that the operation and
service elements are easily accessable. Make sure
that there is enough space (approx. 50 cm) between
the horizontal inlet and any wall.

Mount a gate valve into the inlet pipe and the
discharge pipe to guarantee an easy service or
demounting of the unit.

To avoid sediment build-up in the discharge pipe, the
pipe, and the lifting station should be dimensioned for
a water velocity of minimum 0,7 m/s, for vertical pipes,
however, not lower than 1,0 m/s.

The incoming sewer could be ensues at the horizontal
inlet through a WC-direct connection with 180 or 250
mm, or a DN 100 or DN 50 effluent pipe. Vertical inlets
(DN 50 and DN 100) for service pipe lines are existing.
Cut off the blanked off the vertical or horizontal inlet
and connect a incoming sewer inlet which correspond
to the diameter of the inlet.

To prevent a freezing of the discharge pipe please
isolate the complete discharge pipe up to the sewer
level.

Directly above the swing check valve mount a gate
valve into the discharge pipe.

For a trouble free operation of the pneumatic level
control it is absolutly necessary that the pressure hose
between tank and control box is installed without loops,
bending and constantly rising.

Cut off the blanked off end of the air vent and connect
a DN 70 vent pipe to the tank by means of the flexible
connection supplied. The vent pipe should be led out
into the open air in accordance with local regulations.

Mount the supplied pump controller flood protected on
the wall in accordance with local regulations.

7. Start-Up

Never let the pump run dry for a long time of period,
as it will destroy the pump (danger of overheating).
Before starting the disposal unit make sure that all isolating
valves are open and check that the unit runs satisfactorily.
Turn the operation switch into the position "ON".
In combination with the pneumatic level control the pump
starts and stops according to the liquid level in the tank.

8. Maintenance and Repair

In case of a defect of the pump, a repair shall be
carried out only by the manufacturer or through an
authorized workshop. Modifications of the pump must be
confirmed by the manufacturer. Only original spare parts
shall be used.
In accordance with the product liability law we point out
that we shall not be liable for damages caused by our
product due to unauthorized repair by persons other than
the manufacturer or an authorized workshop or due to the
use of spare parts other than original ones. The same
product liability limitations are valid for accessories.
Before maintenance or repair disconnect the pump
from the power supply to avoid accidental starting of the
pump!
Before maintenance or repair make sure that all
rotating parts stand still!
Before carrying out maintenance and service, the pump
must be thoroughly flushed with clean water. Rinse the
pump parts in clean water after dismanteling.
At pump types with oil chamber an overpressure can
escape with loosening of the oil chamber control screw.
Screw only when pressure balance took place.
Pumps running under normal operation conditions should
be inspected at least once a year. If the pumped liquid is
very muddy or sandy or if the pump is operating
continuously, the pump should be inspected every 1.000
operating hours.
For long and trouble-free operation of the pump, following
points should be checked regularly:
- Nominal current (A): Check with amp-meter.
- Pump parts and impeller: Check for possible wear.
Replace defective parts.
- Ball bearings: Check the shaft for noisy or heavy
operation (turn the shaft by hand). Replace defective ball
bearings. A general overhaul of the pump is usally required
in case of defective ball bearings or poor motor function.
This work must be carried out by an authorized
service workshop.
- Cable entry: Make sure that the cable entry is watertight
and that the cables are not bent sharply and/or pinched.
Additionally at pump types with oil chamber:
Oil level and oil condition:
Put the pump in horizontal position, so that the screw of the
oil chamber is above (at larger pumps: one of both screws).
Remove the screw and inver a small quanity of oil.
The oil becomes greyish white like milk if it contains water.
This may be the result of defective shaft seals.
In this case contact our Sales and Service Department.
The oil should be replaced after 3000 operating hours.
Oil type: Shell Tellus C22. Used oil is to be disposed
accordingly.
Servicing Contract
For a regular expert execution of all necessary
maintenance and inspection we recommend the conclusion
of a servicing contract by our Sales and Service
Department.
