13. Proper Use of the Equipment
This system conveys water under high
pressure to high-pressure cleaning stations
situated downstream of the system. The
system is designed for stationary
installation in a dry indoor environment. At
the installation site, a water and mains
power connection satisfying the criteria
stated in the Specifications section of this
manual must be provided. The
environmental temperature at the
installation site must not rise above 40 °C.
The high-pressure water is distributed via a
fixed-installation tubing network.
Only clean water may be used as a high-
pressure medium. Water contamination of
any kind would cause premature
component wear or lead to deposits within
the system.
In the presence of water hardness
exceeding 15°dH appropriate water
treatment measures for lowering the
hardness point.
The use of recycling water requires prior
discussion with Kärcher.
