Deaeration
To install an automatic deaeration system, it is necessary to remove (by unscrewing) the manual deaerator and fit the cock and automatic
deaerator (optional kit code 072153X0) as shown in the figure.
For connection of the cock (detail 2) use the tape seal in PTFE or other material with duty temperature above 180°C.
If the solar system is deaerated with an automatic deaerator (accessory), close the ball cock after deaeration.
