Flow restrictor

In order to maintain a consistently high tem-
perature (above 90°C) of the water, a pow-
er nozzle must be inserted into the screw
connection of the spray bar to restrict the
flow.
Note
The necessary power nozzle is matched to
the corresponding high-pressure cleaner
and must be ordered separately.
