The water level in the swimmer tank is kept constant by the swimmer valve. In case of failure of the swimmer valve, the water exits via the overflow. If the water supply is disturbed, the lack of wa-ter fuse will send an error message to the controls.The electric engine will drive the crankshaft pump. The pump transports the water under high pressure to the pressure side.The high-pressure water reaches the high-pressure output via the overflow valve and the pressure sensor. After that, there will be the high-pressure network of the operator.Remaining water will be routed back to the suction side of the pump by the overflow valve. If all consumer loads have been switched off, the overflow valve will switch to circulation. If the pressure at the output exceeds the maximum operating pressure at the output, the safety valve will open.– The appliance will be switched to READY mode by activating the release switch. The indicator lamp for operational readiness lights up. If the pressure in the systems sinks below the determined switch-on point due to the opening of a hand spray gun, the high-pressure pump will be switched on.– If the flow switch in the high-pressure line trips after closing all hand spray guns while the pump is run-ning, the pump is switched off again with a delay of 10 seconds (HDC 20/8) or 30 seconds (HDC 20/ 16). – If the system is ready and the high-pressure is not turned on, a timer is started, which will reset the readiness of the unit after 6 hours. The operation readiness indicator lamp goes off.Safety devices serve for the protection of the user and must not be put out of operation or bypassed with re-spect to their function.The safety mechanism against lack of water prevents the high pressure pump from being switched on when there is no water. The temperature sensor switches off the appliance as soon as the water temperature is too high.The winding protection contact in the motor winding of the pump drive switches off the engine when there is a thermal overload. – The safety valve opens when the overflow valve is defective.– The safety valve is set by the manufacturer and sealed. Setting only by customer service.– If the hand spray gun is closed, the overflow valve opens and the entire water volume will flow back to the pump suction side.– If the hand spray gun is closed, the pump is switched off via the flow switch after a stopping time of 10 seconds (HDC 20/8) or 30 seconds (HDC 20/16).If the hand spray gun is opened again, the pressure switch switches on the pump via the pressure sensor.

Indicator lamps Start up Operation Safety instructions 14 EN- 4 DANGERRisk to life on account of electric shock! Do not direct the water jet on the following equipment:– Electrical appliances and plants, – the unit itself, – all electricity-carrying parts in the working area. There is a recoil pressure arising from the water jet that comes out from the spray pipe. The angular spray pipe brings about an upward force. DANGER– Risk of injury! The recoil pressure of the spray pipe can throw you off-balance. You may fall. The spray jet can fly off and cause damage to persons. Search a secure place to stand and hold the gun firmly. Never hold on tightly to the lever of the hand spray gun.– The jet must not be directed at other persons or di-rected by the user at him/herself to clean clothing or footwear.– Risk of injury from parts flying off! Flying-off frag-ments or objects can injure people or animals. Nev-er direct the water jet on fragile or loose objects.– Risk of accident on account of damage! Clean tyres and valves from a minimum distance of 30 cm. DANGERDanger from substances that are harmful to health! Do not spray the following materials as they can swirl up substances that are harmful to health:– Materials containing asbestos,– Materials that could contain substances harmful to health. DANGER– Risk of injury on account of the emanating water jet that could be hot! Only original Kaercher high pres-sure hoses are optimally suited for the plant. No guarantee can be given if you use any other hoses.– Detergents can prove to be a health hazard! If any detergents are added, the water let out of the plant is not of potable quality.– Risk of hearing impairment while working on noise-making parts! If so, wear ear plugs.몇 WARNINGLong hours of using the appliance can cause circulation problems in the hands on account of vibrations.It is not possible to specify a generally valid operation time, since this depends on several factors:– Proneness to blood circulation deficiencies (cold, numb fingers).– Low ambient temperature. Wear warm gloves to protect hands.– A firm grip impedes blood circulation.– Continuous operation is worse than an operation interrupted by pauses.In case of regular, long-term operation of the device and in case of repeated occurrence of the symptoms (e.g. cold, numb fingers) please consult a physician. DANGERRisk of injury on account of the emanating water jet that could be hot! DANGERCheck the high pressure hose for damage before every use.
