- the heating element 36 is coupled to the solenoid valve 14 in such a way that it ensures the heating of the cleaning fluid which is projected by the nozzle 10 connected to the said solenoid valve 14.

- the two nozzles 10 associated with the first two solenoid valves on the distribution circuit are upstream of the first heating element 36a, so that the cleaning fluid which circulates in these two nozzles is not heated, while the other nozzles, downstream of the first heating element 36a, are intended to receive heated cleaning fluid, if the first heating element 36a is piloted to operate and allow heating of the fluid.
- the further one moves away from the first heating element 36a while approaching the second end 22 of the distribution pipe, the less the cleaning fluid has a high temperature. It is thus advantageous to provide the second heating element 36b, in particular in the vicinity of the second end 22 of the distribution pipe 8, to heat the cleaning fluid and restore it to the temperature it had just after passing through the first heating element 36a.

- the heating element 36 is here arranged upstream of the set of solenoid valves 14, that is to say between the interconnection point 42 and the set of solenoid valves 14.
- the heating element 36 ensures the heating of the cleaning fluid prior to its passage through the set of solenoid valves 14 positioned on the additional branch 40.
- distribution pipe 8 may comprise a plurality of additional branches each connected to the main branch by a distinct interconnection point.
- the distribution line 8 comprises three additional branches 40 connected to the main branch 38 by the single point of interconnection 42, each of the additional branches 40 being specific to a sets of 14 separate solenoid valves.
- the heating element 36 is then placed between one of the sets of solenoid valves 14 of one of the additional branches 40 of the circulation conduit 8 and the interconnection point 42.
- the position of the heating element 36 on the distribution pipe 8 makes it possible to heat only the cleaning fluid which passes through the additional branch 40 carrying the set of solenoid valves 14 to which heating element 36 is coupled. And the heating element 36 can heat the cleaning fluid which passes through all the solenoid valves 14 of the set of solenoid valves 14 of the additional branch 40 considered.
