At the beginning of the slide show you will see the old AHU being dismantled.
From here there is a representative slide show of the assembly of a small purpose built AHU for a small Office system.
The unit was designed, Assembled and tested at the Factory and then disassembled for transport to site.
Due to the access problems the unit had to be ferried in sections to the roof for assembly.
Some additional drillings were necessary for the final securing of items within the Cabinet.
