6. Safety
For safety reasons, all work in tanks must be
supervised by a person outside the pump tank.
Tanks for submersible wastewater pumps contain
wastewater with toxic and/or disease-causing
substances. Therefore, all persons involved must
wear appropriate personal protective equipment and
clothing and all work on and near the pump must be
carried out under strict observance of the hygiene
regulations in force.
7. Transportation and storage
The pump may be transported and stored in a
vertical or horizontal position. Make sure that the
pump cannot roll or fall over.
Check that the protective cap for the level sensor
has not been damaged during transportation.
See fig. 1, 2 or 3 (pos. 7). If the protective cap is
defective, contact your nearest Grundfos company.
All lifting equipment must be rated for the purpose
and checked for damage before any attempts to lift
the pump. The lifting equipment rating must under no
circumstances be exceeded. The pump weight is
stated on the pump nameplate.
The polyurethane-embedded plug prevents water
from penetrating into the motor via the motor cable.
For long periods of storage, the pump must be
protected against moisture and heat.
After a long period of storage, the pump should be
inspected before it is put into operation. Make sure
that the impeller can rotate freely. Pay special
attention to the shaft seal, cable entry and sensors.
8. Installation
The additional nameplate supplied with the pump
can be fixed close to the tank.
All safety regulations must be observed at the
installation site, for instance the use of blowers for
fresh-air supply to the tank.
Prior to installation, check the oil level in the oil
chamber. See section

The pumps are suitable for different installation types
which are described in sections
