When air temperatures are wintery,
and after general stoppage of the
installation, the water contained in
the plate exchanger may freeze.
To prevent such problems, fully
drain the unused plate exchanger or
protect it by pouring an antifreeze
solution into the hydraulic circuit or
other devices.
The manufacturer waives any
liability for damage to the plate
exchanger caused by water freezing
inside the unit.
Whenever there is a risk of freezing
