Installing the isCon system 

•  Position the interception rod stand on the concrete plinths.

Figure 48:  

Positioning the interception rod stand

•  Determine the inclination of the interception rod stand (depending on 

the slope of the roof) using a spirit level.

•  Compensate for the inclination of the interception rod stand using the 

hexagonal height compensation nuts (max. 5 degrees).

•  Tighten the lock nuts.

max. 5°
