Flow restrictor

To ensure the water temperature remains
even (above 90°C), you will need to install
a flow restrictor on the high-pressure output
of the high-pressure cleaner.
Note
The required adapter is not included in the
scope of delivery. The required nozzle has
been adjusted to suit the corresponding
high pressure cleaner and must be ordered
separately.
