5.1.3 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.
