For mounting the steel frame you need two steel bars (HYCON special tool No.
9992079) to be inserted in the pipes. Pull the pipes away from each other and push
in the steel frame in between. Push the frame a little into the plastic cover, pull out
the steel bars, and then push the frame completely into the cover. Again use the
steel bars to catch the pipes inside the plastic cover, and push out the two pipes
through the steel frame.
