5.2 Electrical connection

Electrical connection should be made by a qualified electrician. Current national regula-
tions must be observed (e.g. VDE regulations in Germany).
Check that the mains current and voltage comply with the data on the rating plate
Mains fuse: 16 A, time-lag
Pump/installation must be earthed in compliance with regulations
In accordance with EN 60335, submersible driven-motor pumps with less than 10 m of connect-
ing cable are only permitted for use within buildings, in other words not for operation in open
air.

6 Operation

To reach a optimum suction-process, it is necessary to fill the pump housing with water using the
hopper cap
The mechanical seal must not run dry!
ATTENTION!
- Dry running reduces the life of motor and mechanical seal.
- Fill in some water !

7 Maintenance

In order to avoid infection maintenance work should only be carried out using protective
gloves.
For all maintenance and repair work the pump is to be switched off-circuit and pro-
tected against unauthorised re-starting.
In principle, damage to the connecting cable should only be repaired by a qualified elec-
trician.
