16 EN- 3 The water flows back from the swimmer tank to the suc- tion side of the pump. 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 floater basin by the overflow valve. If all consumer loads have been switched off, the overflow valve will completely switch to backflow to the floater basin. If the pressure at the out- put exceeds the maximum operating pressure at the output, the safety valves will open. – The appliance will be switched to READY mode by activating the release switch. 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 pumps will be switched on. The first pump is switched on via the frequence in- verter, all remaining pumps are operated directly via the mains. – If the flowmeter at the overflow valve is triggered while the high-pressure pumps are running after closing all hand sprayguns, the pump is switched off once again with a 30 second delay. – If the system is ready and the high-pressure pumps are not turned on, a timer is started, which will reset the readiness of the unit when the preset time has elapsed. 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 pumps 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 all hand spray guns are closed, the overflow valve opens and the entire water volume will flow back into the floater basin. The high pressure pumps are switched off via the flowmeter once the set delay time has elapsed. – The remaining water flows back into the floater ba- sin via the overflow valve. If the hand spray gun is opened again, the high pres- sure pumps will restart via the pressure sensor for high pressure.

If they are not in a perfect state then the appliance must not be used.The operator must use the appliance correctly. When working with the appliance, he must consider the local conditions and pay due care and attention to other per-sons, in particular children, who are nearby.Never leave the appliance unattended when it is in op-eration. DANGER– Danger of scalding by hot water! Do not direct the water jet on persons or animals.– Risk of burns on account of hot surfaces! Do not touch uninsulated pipes and hoses when hot water operations are on. Hold the jet pipe only at the han-dles.– Risk of poisoning or itching on account of deter-gent! Follow the given instructions for using deter-gents. Store detergents safely and protect them against access by unauthorised persons. 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.Note: The text is shown in English.A Unlocking buttonB LCD displayC Bar graph (approx. 20% of the nominal pressure per field)D Fault message pumps 1-4E Change value (-) or move cursor to the leftF Change value (+) or move cursor to the rightG Acknowledgment button (OK)H Cancel (ESC)I System pressureJ Collective faultK Water shortageL The respective pump is switched on.– When the system is ready to operate, the current operating hours of the high pressure pumps are shown alternating with the operating pressure.– When errors are triggered, these are shown on the display as well (see "Help with errors"). DANGERRisk of injury on account of the emanating water jet that could be hot! DANGERCheck the high pressure hose for damage before every use. Please arrange for the immediate replacement of a damaged high pressure hose. Check high pressure hose, pipe connections, fit-tings and water jet for damage every time before use.
