3.0   How to install the coupler  

 

1.  To assure a safe function the NTS-PU needs to be installed as follows: 

a.  Tensile force either axial or at an angle 
b.  The coupling halves need to have enough space to fully separate. 
 
 

This guarantees the complete closure of the valves. 

 
 

For all sizes 1

 - 4

 (DN25 – DN100) the minimal required distance between the two halves is 

4’’ (100mm) at the point of separation. 

 
2.  The NTS-PU can be installed in any direction. 
 
3.  Installation should not lead to stress on the production line. 
 
 

 

 

4.  Mounting screws must be removed before the use of the NTS-PU 

 
5.  During the separation small amounts of media could escape. We therefore recommend an  
 

additional spray protection. 

 
6.  The user manual (installation instructions) and the mounting screws should be kept in  
 

secure and accessible location. 

 

 

Caution! 

The Valves of the NTS-PU are spring loaded.  

Inappropriate disassembly could lead to injuries! 

 

7.  Warning ! 

 

During the loading or offloading process no person should be standing in the danger zone of 
the NTS. The separated hose end might pose an injury danger during the separation process. 
Emergency contingencies are to be followed according to local regulations and jurisdictions.
