Isolate the equipment before any maintenance work is done. Switch off the mains
supply, remove fuses, apply lockouts where applicable and affix suitable isolation
warning signs to prevent inadvertent re-connection.
In order to avoid the possibility of maintenance personnel inhaling dangerous fumes or
vapours, it is recommended that maintenance work be carried out away from the
pump location by removal of the rotating unit assembly to a suitable maintenance
area.
