INFORMATION ABOUT USE
Par. 3.2.2. • An anti-freeze protection liquid (ANTIFREEZE) - mixed with
decalcified water - must be used.
• The freezing point of the refrigerant mixture depends on the
amount concentration in water.
• As well as lowering the freezing point, the antifreeze also
raises the boiling point.
• A 50% mixture is recommended to ensure a general level at
protection prevents the formation of rust, galvanic currents
and calcium deposits.
