Assembly with quick-change frame (option)

The quick-change frame offers maximum flexibility in dismantling and assembly of the cooling units.
The cooling units are therefore quick and easy to assemble. – The assembly cut-outs and fastening points are identical with
those for the assembly of the cooling unit alone, see chapter "Dimensions of the unit cut-out", Page 33.
– The quick-change frame is therefore easy to retrofit, see chapter "Spare parts and accessories", Page 75.
The quick-change frame has a central locking mechanism which guarantees an absolutely secure connection to the DTT-
cooling unit.
