NOTE:
Before installation, it is recommended to carry out accurate flushing of all the pipes of the system in order to remove any residue or impurities that 
could endanger correct operation of the HIU.
In order to facilitate these operations a manual bypass flushing valve is available (code 789110).

N.B.:
In the case of installation with connections 
on the bottom fit the safety screw (figure

Install SATK32 as per the above pictures 
and close the 6 nuts using the fiber gaskets 
supplied.
