Space requirements:
At the location, for proper maintenance and installation of components there should be adequate
space for the devices. Therefore, a free working space of AHU width + 300 mm needs to be availa-
ble.
At the rear of the machine, a 600 mm width passage should remain free between the machine and
the fabric of the building.
According to EN 13053 and VDI 3803 it is not permitted, that the bottom of the AHU replaces the
building roof. Furthermore, it is not permitted that the AHU substitutes any part of the building.
4.1 Foundation
Recommended are solid foundations of reinforced concrete, as shown in
foundations, as shown in
right. For strip foundations, concrete or steel beams shall be
bottom-right. Steel beams constructions must have an appropriate stiffness in
relation to the AHU size. The foundation must be flat and leveled, it should have gradients in any
direction or uneven surfaces.
Following conditions must be fulfilled:
-
The height difference of the foundation may be
1 mm per meter maximum
. For the entire
AHU length and width, a height difference of
5 mm maximum
is acceptable.
-
If the conditions mentioned before are not fulfilled due to uneven foundations or sagging of the
foundation, measures for rectifying the conditions must be taken (e.g. distance sheets with ap-
propriate thickness).
Attention!
If these structural conditions are not met, this could be the cause problems including of jammed
doors and dampers and other problems with the AHU.
