Poor entrance door installation

[Mr Blobby]

Our internorm AT540 entrance door is an ongoing headache.

 

The door is connected to 1m sidelights either side. 

The first time it was installed the window fitters didn't bother with the coupling unit but just glued the door frame to the sidelights with silicone glue stuff.  Messy to look at  and I could see daylight between the door and sidelights.  Fitters also pinched the electrical cable in the join and the electrics are knackered.

 

Reinstalled now but where the cable was pinched this has prevented the sidelights and door frame from fitting tight together, either because the cable is pinched again or the frame is bent from the first install.

 

The coupling unit is a set of bubble seals and small plastic "H" shapes that fit in internal grooves in the frame.  Fitters reapplied silicone at the joint in the second install.  Not sure if that's a good idea. 

Its still a crap job and we need to decide waht to do.

 

As far as I can see the installation instructions for the entrance door coupling units are not in the public domain.  They would be useful to show the installers!  Does anyone have a copy or some experience of how the coupling unit should be installed?

 

For anyone with an internorm, or similar entance door with big sidelights, how was your door coupled to the sidelights, and am I right to think the use of silicone here is just wrong?
