6.6 Cooling circuit

The housing is equipped with an input and output
joint on the cooling circuit, both of which are
threaded 1/2" Gas.
Installation and dispersal of heat requirements
mean the position of the input and output joints on
the cooling circuit must be adapted to the specific
situation.
The two joints on the cooling circuit placed near
the front (01) and rear (02) flange can be used
indifferently for cooling liquid input and output.
If necessary, the housing can be rotated on its fixing
base by loosening the two fixing clips (03).
