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 high­pressure 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.
Also applicable are the (German) Regulations governing liquid spraying devices, VBG 87, and the Ordinance on Hazardous Substances VBG ZH 1/220 (GefStoffV).
