1.3 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 medium. Skin contact with heated rotating
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 dan-
ger.
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 medium, which meet, the specifications for the application.
If you use incorrect hoses, they may become porous or burst. This can cause personal injury and/or
property damage to components of the machine.
Q
In case of the medium hydraulic oil, use hoses which are suitable for the maximum system pres-
sure of the machine and the maximum temperature of the media.
Hoses for leakage lines
If the cross-section of the hose used is smaller than that of the connection of the rotating union, an ex-
cessive pressure may develop in the hoses. Hoses may burst and cause serious injuries.
Q
Use hoses which fit the cross-section of the connections.
1.3.3 Hazards due to the media
When working on the rotating union, injuries can be caused by skin or eye contact with the media.
Q
Observe the safety instructions for the flow media. Observe the COSHH Safety Data Sheet for
the flow media.
1.3.4 Hazards by faulty installation
If the rotating unions are installed incorrectly, hoses and connections may become leaky. The medium
can escape. Depending on the medium, personal injury or property damage to the components of the
machine may occur.
Q
Before installing the rotating union ensure that no feed pressure and no residual pressure is ap-
plied 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 hoses to the rotating union prior to mounting it at the machine shaft.
