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 veno-
mous 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.
Never put a hand or finger into suction inlet or dischar-
ge of the pump while the impeller is rotating.
Persons are not permitted to stay in the pumping medi-

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 bre-
aker.
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 contai-
ning great quantities of abrasive solids, like sand or stones.
Before the pumping of chemically aggressive liquids, 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).
