6. 1 .4 EXTERNAL HYDRAULIC
CIRCUIT ANR (NOT
SUPPLIED)
The choice and the installation of com-
ponents external to the ANR is up to the
installer, who must operate according
to the rules of good technical design
and in compliance with the regulations
in force in the country of destination
(Ministerial Decree 329/2004).
In any case, we recommend installing
