Decommissioning/dismantling
▪ Operation/control: Operating personnel must be instructed in the functioning of the
complete system.
▪ Electrical work: A qualified electrician must carry out the electrical work.
▪ Installation/dismantling: The technician must be trained in the use of the necessary
tools and fixation materials for the relevant construction site.
▪ Locally applicable accident prevention and safety regulations of trade associations.
▪ Observe regulations for working with heavy loads and under suspended loads.
▪ Provide the necessary protective equipment and make sure that the personnel wears it.
▪ Provide adequate aeration in closed rooms.
▪ Take immediate countermeasures if there is a build-up of toxic or suffocating gases!
The pump is deactivated during decommissioning, but remains installed. This ensures
that the pump is always ready for operation.
‡
To protect the pump from frost and ice, always immerse the pump completely in
the fluid.
‡
The temperature of the fluid must always be above +3 °C (+37 °F).
1. Switch off the pump at the operating point.
2. Secure the operating point against being switched on again by unauthorised per-
sons (e.g. lock main switch).
▶ The pump is out of operation and can now be dismantled.
If the pump remains installed after decommissioning, observe the following:
▪ Ensure that the prerequisites for decommissioning are maintained for the complete
period of decommissioning. If these prerequisites cannot be guaranteed, dismantle the
pump after decommissioning!
▪ For an extended period of decommissioning, carry out a 5-minute function test at reg-
ular intervals (monthly to quarterly). CAUTION! A function test may only be carried
out under the applicable operating conditions. A dry run is not permitted! Non-com-
pliance can result in irreparable damage!
DANGER
Danger due to fluids hazardous to health!
If the pump is used in fluids hazardous to health, decontaminate the pump after dis-
mantling and before carrying out any other work! There is a risk of fatal injury! Ob-
serve the specifications in the work regulations! The operator must make sure that
the personnel have received and read the work regulations!
DANGER
Risk of death due to electrocution!
Improper conduct when carrying out electrical work can lead to death due to electric
shock! Electrical work must be carried out by a qualified electrician in accordance
with the locally applicable regulations.
DANGER
Risk of fatal injury due to dangerous lone working practices!
Work in chambers and narrow rooms as well as work involving risk of falling are dan-
gerous work. Such work may not be carried out autonomously! A second person
must be present for safety reasons.
WARNING
Risk of burns from hot surfaces!
Motor housing can become hot during operation. It may cause burns. Allow the
pump to cool down at ambient temperature after switching it off!
