3.4.6 Assembly with quick-release frame
The quick-release frame offers maximum flexibility for assembly and removal of cooling units.
It makes replacement of cooling units quick and easy. The assembly cut-outs and fastening points are identical to
those for assembly of the cooling unit alone; see figure cut-outs for the DTT cooling unit. This makes retrofitting
with the quick-release frame simple and easy; see ordering spare parts and accessory parts.
The quick-release frame has a central locking mechanism that guarantees an absolutely secure connection with
the DTT cooling unit.
