3. Safety
3.1 Introduction
The rotary joint was designed and built according to the latest technology and complies with
the pertinent safety regulations. However, the rotary joint may still cause dangers if it is not
used as intended and according to the instructions or if it used by untrained staff or if it is tam-
pered with in any way.
Never tamper with the rotary joint or modify it in any way as this may adversely affect the safe-
ty and the performance of the rotary joint. We shall not be liable for any damages resulting
from unauthorized modification of the rotary joint.
We strongly advise the owner/operator of the rotary joint to check his safety concept in terms
of the effects a failure of the rotary joint may have on the environment. Make sure to take all
additional safety measures required to protect persons and the environment

General safety information
Always keep the operating instructions at the installation site for quick and easy access.
In addition to the instructions provided in this manual, you must also observe all the perti-
nent regulations and guidelines concerning workplace safety and prevention of accidents.
Provide a sufficient torque support for the rotary joint.
Use only flexible elements for housing connections. Do not apply forces to the housing via
the connections.
Only perform work on the rotary joint when the machine/system is at a standstill and the
pressure released.
Only operate the rotary joint if it is in perfect technical condition. Only use the rotary joint
according to the instructions and specifications; never operate the unit outside of the
framework of the specifications and performance data indicated. Be aware of all pertinent
safety and danger aspects when operating the rotary joint. Immediately repair any mal-
functions or problems or have such malfunctions or problems repaired as they may inter-
fere with the safety of the rotary joint!
The service life of counter-rotating parts is limited. Therefore, perform preventive main-
tenance of seals and bearings after no more than 12 months!
If you need to dismantle safety devices for repair or maintenance of the rotary joint, you
must refit such devices immediately upon completion of the work and check the proper
function of the devices!
When replacing the rotary joint, carefully fasten it to appropriate lifting gear and secure it
in such a way that it cannot cause danger. Use only suitable lifting gear which is in perfect
technical condition and which has a sufficient rating for the load to be lifted! Never step or
work below suspended loads!
Retighten all screw connections that you may have loosened for maintenance or repair
work! Refer to the section "Specifications and Spare Parts" for information on the tighten-
ing torques.
Use only genuine spare parts for repairs.
