5. Frost protection
The parts carrying water must be protected against frost,
as they can otherwise be destroyed. If the high-pressure
module is to be operated during frosty periods, it must be
installed in a frost-free location. Outdoorwater pipes must
be frost proof (e.g. insulation and steam tracing) or must
be drained during the frost period.
6. Shutdown
If the high-pressure module is to be shutdown during the
frost period, it has to be flushed with an anti-freeze soluti-
on first.
Anti-freeze solutions generally protect against corrosion
at the same time.
