Warning

• 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.
