Safety Instructions

This chapter provides information on the hazards through rotating unions.

1.3.1 Hazards due to hot surfaces

The rotating unions are heated by the temperature of the flow medium. Skin contact with heated rotat-
ing unions can cause injuries.
Q Use safety gloves and PPE (Personal Protective Equipment) protecting against heat when han-
dling the rotating union.
Q Attach a clearly visible danger sign visibly on/next to the rotating union in order to warn of
danger.

1.3.2 Hazards by improper hoses

For the connection of the rotating union to the machine, you have to choose appropriate hoses for the
respective flow media the specification of which meets the application.
If you use improper hoses, the latter may become porous or burst. This can cause personal injury and/
or property damage to components of the machine.
Q In case of the flow media water, steam and thermal oil, use hoses that are suitable for the maxi-
mum system pressure of the machine and the maximum temperature of the flow media.
Q Flexible hoses have a limited service life. Hence they are to be replaced at appropriate intervals.

1.3.3 Hazards due to the flow medium

When working on the rotating union, injuries can be caused by skin or eye contact with the flow me-
dium.
Q Observe the security instructions for the flow medium.

1.3.4 Hazards by faulty installation

If the rotating unions are installed incorrectly, hoses and connections may become leaky. The flow
medium can escape. Depending on the flow medium, personal injury or property damage to the com-
ponents of the machine may occur.
Q Before installing the rotating union ensure that no feed pressure and no residual pressure is
applied to the pipeline system of the machine.
Q Install the rotating union on the machine using hoses only, in order to avoid stress on the rotat-
ing union.
Q Install the hoses free from stress.
Q Install the rotating union in a way that the leaking medium can be carried away downward at
the lowest point.
Q Install the hoses to the rotating union prior to mounting it at the machine shaft.
