3.1.1 

Mounting the clamping element 

There are three options how to connect the device to the process: 

  

 

Figure 1:  mounting options: a) clamping block, b) clamping shoe and c) clamping bracket 

  

3.1.1.1 

Mounting the clamping block 

Required tools: 

Hexagon socket wrench 3 mm (mounting screws) 

Hexagon socket wrench 2 mm (vibration protection) 

  

  Turn  back  the  vibration  protection,  so  that  it 

does not exceed the semi-cycle groove for the 
pipe (see picture to the right). 

  Mount  the  clamping  block  with  the  included 

screws at the intended position on the pipe. Do 
not  exceed  the  allowed  tightening  torque  of  2 
Nm  for  pipe  diameters  up  to  17,2  mm  and  4 
Nm for bigger pipes. 

  Hand-tighten  the  vibration  protection.  Do  not 

tighten the vibration protection screw too hard. 
You  might  damage  the  clamping  block  or  the 
pipe.

3.1.1.2 

Mounting the clamping shoe 

Required tools: 

depends on the used hose clamps 

  

  Mount  the  clamping  shoe  with  two  appropriate  hose  clamps  or  tightening  straps. 

The maximum width for a safe fit is 5 mm. 

  Tighten the clamps so that the clamping shoe cannot be moved by hand applying a 

usual hand force.
