2. Safety Warnings

2.1. General Instructions

Signs used to mark instructions in this manual
Safety instructions in these operating instructions,
which, if not observed, could cause a danger for persons
are marked with the general symbol in accordance with
DIN 4844-W 9.
Warnings against electrical voltage are marked with
the safety symbol in accordance with DIN 4844-W 8.

2.2. General Safety Precautions

General regulations and guidelines not mentioned in the
safety warnings retain their validity.
These operating instructions contain basic instruc-
tions, which have to be adhered to during installation, op-
eration and maintenance. These operating instructions
must be read from mechanic and the operator before in-
stallation and operation of the pump and have to be kept
available at the operating place of the machine/unit at all
times. Persons who are not familiar with the operating
instructions shall not use this product.
Children and adolescents under age 16 shall not use
the unit and must keep away from the machine/unit
while it is operational.
The unit must be installed from a technical experi-
enced plumber.
Never work alone.
Please make sure that used aids e.g.hoisting crane
are in regular and reliable contiditions.
The working area has to be closed off expediently
and must adhere to local workplace regulations.
Always use personal safety equipment such as safety
boots, rubber gloves, safety glasses and helmet.
Make sure that the emergency exit from the work-
place is not barricaded.
To prevent suffocation and poisoning caused by
venomous gases, make sure that enough oxygen exists
at the workplace.
If you have to work with welding tools or electric tools,
make sure that there is no explosion hazard.
Immediately after repair or maintenance work, all
safety and protection equipment must be reinstalled and
placed in function again.
The operator of the pump is responsible for third
parties within the work area.
All other rules and regulations and local codes cover-
ing health and safety must be observed. In accordance
with product liability law, we point out that we shall not be
liable for damages caused by the pump due to non-
observance of the instructions and guidelines set forth in
the operating instructions. The same product liability are
valid for accessories.
3. Applications and Technical Description

3.1. Applications

The pump station
The pump station will be installed in building which are
below the sewer level or have not enough natural fall to
the canalisation.
Bevor the pumping of chemically aggressive liquids, the
resistance of the pump materials must be checked.

3.2. Product Description

Smell-tight and watertight pump station with one or two
pumps. The pump station consists of a collecting tank with
all necessary ports for the connection of inlet pipe, dis-
charge pipe and air vent. (see page 21).
Collecting- Material
tank
PE 4.. Polyethylene
PE 8.. Polyethylene
The controllers incorporate contactors, a pc-board with
light-emitting diodes ( LEDs ) for indication of operating
condition, relays and a pressure switch. The level switch
is operated by the liquid level in the collecting tank via a
hose.
The LEDs indicat :
- Pump operation (each pump)
- Phase sequence fault (three-phase only)
- Fault (each pump)
- Alarm
A thermal switch incorporated in the motor windings will
protect the motor from overheating by cutting off the sup-
ply to the pump via the controller.
A back-up accumulator maintaining the alarm signal in
case of supply failure is available as an accessory. The
accumulator is fitted inside the controller via a plug and
ensures that an alarm can be given within 15 hours after
the electricity supply has been switched off.
The accumulator is fully charged on delivery. The charg-
ing time is approx. 100 hours. The accumulator is auto-
matically charged when the electricity supply is switched
on.
Note : Used up accumulators must be disposes of in ac-
cordance with local regulations.
Three-phase controllers incorporate a phase monitoring
function which does not, however, prevent the motor from
starting in the event of wrong phase sequence of the
mains connection.
In addition to the LEDs, the controller front cover features:
- Function selector with the positions: 'Test' (manuell
operation), 'Aus' (turn off)and 'Auto' (automatic opera-
tion).
- On/off switch for built-in acoustic alarm.
Pump Control (Single station)
When the liquid level in the tank reaches the start level, if
the liquid level continues to rise when the pump is operat-
ing, an alarm is given until the liquid level is lowered be-
low the alarm level. If the liquid level reaches the stop
level in the tank, the pump will stop.
