Establishing the screw connection of AHU parts

The exact alignment of the AHU parts and pulling together of the AHU parts as close as possible, as
described in chapter 5.1.1(Actions before the assembly of casing), are requirements for estab-
lishing screw connection.
The precisely aligned and parallel flanges are connected with the enclosed bolts. Initially, all bolts
are only loosely screwed as follows:
In the base frame profiles (Figure 28).
-
In the connection angles located in the upper corners of the AHU (Figure 29).
-
-
For roof AHUs in the roof flange.
After placing all the screws loosely, they shall be tightened - starting with the base frame – in two
stages.
