1. Safety information
General safety precautions
During installation, operation, maintenance or repairs to the system, please observe the accident pre-
vention regulations, the applicable DIN and VDE standards and guidelines, and also the regulations of
the local energy and supply companies.
The systems may not be operated in explosive areas
Electrical hazards
This system contains electrical voltages and controls rotating mechanical parts. Non-observation of the
operating instructions could lead to serious damage, injury or even fatal accidents.
The system must be securely disconnected from the mains supply before commencing any work on it.
The local master switch and the cut-outs must be turned off, i.e. switch the system to zero-potential and
take precautions to ensure it cannot be switched on again. If only cut-outs are available, these must be
switched off and a sign attached to prevent third parties from switching the main fuse on again.
VDE 0100 applies to all electrical work on the system.
The switchgear and the level control are under voltage and may not be opened. Only electricians may
work on the electrical equipment. The term 'electrician' is defined in the VDE 0105.
Steps must be taken to ensure that the electrical cables and all other electrical system parts are in a
fully functional condition. If any parts are damaged, the system may not be operated and/or must be im-
mediately shut down.
Risk of burning fingers and hands
The driving engine may become very hot during operation
Risk of injury to fingers and hands
The pumps are equipped with a closed impeller. Therefore work on the pump may only be carried out if
the power supply has been disconnected and the rotating parts have stopped rotating.
Take care on sharp edges during maintenance or repair work.
Risk due to heavy weights
The lifting system models with one pump weigh around 45 kg, and with two pumps around 84 kg. The
systems may only be lifted or mounted by two persons with appropriate care wearing protective equip-
ment (e.g. protective shoes).
The pumps may only be removed slowly or placed in the pump flange opening by two persons (if sui-
table precautions to prevent slipping have been taken).
