ATTENTION
During the reassembly of the nozzle-holder assembly screw the nut (3) as shown in fig. 15.
In order to guarantee the sealing of the fan in its seat, make sure that there is at least 1 mm of spring tension
between nozzle-holder assembly and casing. Therefore the fixing split pin (11) will have to be extended at
least of 1 mm beyond the flange of the nozzle-holder assembly.
