4.5 Foundation
The unit should be placed on:
- a foundation slab
- a steel base frame concreted into the floor
- an appropriate stiff steelwork
The foundation, steel base frame or steelwork have to be flat and leveled and they should be able to
support the weight of the unit.
In AHUs situated one on another the part of the upper AHU projecting outside the outline of the
bottom one must be supported with the use of an appropriate construction fig. 6a.
Height of the foundation slab or base frame must allow for assembly of the siphon which drains the
condensate out of the draining tray. In case of the drain plates installed in the lower AHU sections,
the unit has to be mounted onto additional foundation slab or a special hollow must be made directly
under the siphon.
