This washer-disinfector is supplied as standard for a pressurised sys-
tem operating between 30-1,000 kPa (UK: 100-1,000 kPa). If the wa-
ter pressure is below 200 kPa the water intake duration will be auto-
matically increased.
The pressure tested hose for AD water, coded green, has a ¾ inch
threaded union for connection to the onsite stopcock for AD water.
If the washer-disinfector is not going to be connected to demin-
eralised (DI) water, the DI water connection has to be deactivated
by the W&H Customer Service Department. The intake hose re-
mains on the back of the machine.
The machine can be connected to a ring line system for DI water. For
this purpose, it must be technically adapted and the controls reset by
the W&H Customer Service Department.
Please contact the W&H Customer Service Department for further
information.
