Decommissioning/removal
▪ Make available the required protective equipment and ensure that the personnel wear the
protective equipment.
▪ Ensure sufficient aeration in closed rooms.
▪ If toxic or suffocating gases build up, immediately initiate countermeasures!
During decommissioning the pump is switched off, but remains installed. This ensures that
the pump is always ready for operation.
‡
In order that the pump is protected from frost and ice, always completely immerse the
pump 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 unauthorized switch-on (e.g. seal off the main
switch).
▶ The pump is out of service and can now be disassembled.
If the pump remains installed after decommissioning, observe the following points:
▪ Ensure requirements for decommissioning for the complete time period of decommission-
ing. If the requirements are not guaranteed, remove the pump following decommissioning!
▪ In the case of an extended time period of decommissioning, carry out a 5 minute test run
(monthly to quarterly) at regular intervals. CAUTION! Test runs must only take place under
the applicable operating conditions. Never run the machine dry!This can result in total
failure!
