5.1.4 Establishing the screw connection of AHU parts
The exact alignment of the AHU parts and pulling together AHU sections as close as possible, as
described in
chapter 5.1.1
(
Actions before the assembly of casing
), are vital for establishing
easier insertions of bolts and screws through the corresponding holes.
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 83
left).
-
If accessible, in the connection angles located in the upper corners of the AHU (
Figure 83
bot-
tom center).
-
If accessible, in the parameter of the connection frame (
Figure 83
top center).
-
In the panels (
Figure 83
right).
-
For roof AHUs in the roof flange.
If only one side is accessible (panels and connection frame) the tapping screws ø8 x 11 or Ejot ø8
x 16 should be used, otherwise bolts and nuts (all supplied separately):
-
Bolts M8 x 20 for connection angles and base frame
-
Bolts M6 x 16 for connection frame and panels
For the tightness at least every second hole (bolt spacing 305 mm) shall be used.
