According to applicable regulations, the device must never be used with the drinking water network without a system separator. Use a system separator from KÄRCHER or a system separator as per EN 12729 Type BA. Water that has flowed through a system separator is classified as undrinkable. Always connect the system separator to the water supply and never directly to the water connection on the device.

• See the “Technical data” for the connected loads.

Note
The supply hose is not included in the scope of delivery.

Note
The system separator is not included in the scope of delivery.

1. Connect the system separator to the water inlet (e.g. tap).

Risk of injury and damage, contamination of drinking water
Never extract fluids containing solvents such as paint thinner, petrol, oil or unfiltered water. The seals in the device are not resistant to solvents. The spray mist of solvents is highly flammable, explosive and poisonous. Never extract water from drinking water tanks.

1. Connect the suction hose (diameter at least 3/4”) to the water connection of the device.
2. Hang the suction hose in an external water source.

Note
Maximum suction height: 0.5 m

3. Until the pump draws in water: Set the pressure/quantity regulator of the pump unit to the maximum value.

Electrical connection

  DANGER
Unsuitable electrical extension cables
Electric shock
Only use approved and appropriately marked electrical extension cables with a sufficient line cross section for outdoors.
Make sure that the plug and coupling of an extension cable used are watertight.
Always unroll extension cables completely.

ATTENTION
Exceeding the grid impedance
Electrical shock in the event of a short-circuit
The maximum permissible mains grid impedance at the electrical connection point (see Technical data) must not be exceeded.
Contact your electricity supplier in the case of any uncertainties regarding the mains grid impedance at your electrical connection point.

• For connected loads, see technical data and type plate.
• The electrical connection must be carried out by an electrician and comply with IEC 60364-1.
• Check the correct polarity of the device, see Operation / Polarity inverter switch.
