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 mentoined in the
safety warnings retain their validity.
These operating instructions contain basic instructions,
which have to be adhered to during installation, operation
and maintenance. These operating instructions must be
read from mechanic and the operator before installation
and operation of the pump and have to be kept available at
the operating place of the machine/unit at all times. Per-
sons who are not familiar with the operating instructions
shall not use this product.
Children and adolescents under age 16 shall not use
the pump and must keep away from the machine/unit
while it is operational.
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 workplace
is not barricaded.
To prevent suffocation and poisoning caused by ven-
omous 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 par-
ties within the work area.
Never put a hand or finger into suction inlet or dis-
charge of the pump while the impeller is rotating.
Persons are not permitted to stay in the pumping me-
dium during operation of the pump.
All other rules and regulations and local codes covering
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 acces-
sories.

3. Applications and Technical Description

3.1. Applications

If the pump is used for cleaning or maintenance of
swimming pools, make sure that no persons stay in the
swimming pool during operation of the pump and that the
pump is self-assured by a 30 mA earth leakage circuit
breaker.
A Series pumps are designed for pumping waste water or
effluent containing sludge or soft solids.
The pumps are used for installations in public and private
sector, trade and industry.
The pumps must not be used for pumping of liquids con-
taining great quantities of abrasive solids, like sand or
stones. Before the pumping of chemically aggressive liq-
uids, the resistance of the pump materials must be
checked.
The pumps may be used for both temporary or permanent
installation. The installation can be free-standing on a
base-stand or by means of an auto-coupling guide rail
system (available as accessory).

Information for the operation on a frequency
converter:
As a minimum, properly sized load reactors and filters must
be installed between the inverter and the pump to protect
the pump motor from damaging voltage spikes. Warranty
coverage will not be provided on any pump motor that is
operated with a variable frequency drive, unless the load
side of the inverter is properly isolated from the pump.
3.3. Operating Conditions
Maximum liquid temperature: 35°C, short term up to
60°C.
Density of pumped liquid: max. 1100 kg/m
Ph-value of pumped liquid: 5 up to 11.
Level of pumped liquid: The lowest level must always be
above the top of the pump housing (volute).
Operation: The motors are designed for continuous opera-
tion (S1) with fully submerged motor, maximum 15 starts
per hour. Our standard warranty and maintenance regula-
tions refer to intermittent operation. For reduced warranty
periods and service intervals due to continuous operating
conditions please contact our service
department.

3.4. Explosive enviroments

For operation of the pumps in explosive enviroments
only models with explosion-proof motors (Ex model) must
be used.
It is important to take notice of „Installation and Opera-
tion Instruction Manual of the explosion classification (Ex-
class) of the submersible pump".
For each individual installation the explosion classifica-
tion (Ex-class) of the pump must be approved by the local
authorities.
