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.
❑
Before installing the rotating union ensure that no feed pressure and no residual pressure is
applied to the pipeline system of the machine.
- Please follow the additional instruction “Installation” for a secure and correct installation of
the rotating union. The installation instruction is included with the delivered union.
❑
Install the hoses to the rotating union prior to mounting it at the machine shaft. This does not
apply to hoses with an SAE connection.
❑
Install the anti-rotation element on the rotating union, tension free.
❑
Make sure that the hoses are connected in compliance with the channel configuration of the
rotating union. Pay attention to the model specific installation drawing.
❑
Install the rotating union on the machine using hoses only, in order to avoid stress on the rotat-
ing union.
❑
Install the hoses free from stress.
❑
Rotating Unions with leakage line: Install the rotating union in a way that the leaking medium
can be carried away securely downward at the lowest point and that the drain line shows a fall
(min. 15°).
