Danger For an immediate danger which can lead to severe injuries or death. 몇 Warning For a possibly dangerous situation which could lead to severe injuries or death. Caution For a possibly dangerous situation which can lead to minor injuries or property dam- age. Danger of death Violating these safety instructions may re- sult in death through electrocution. Check the power cord with mains plug for damage before every use. If the power cord is damaged, please arrange immediately for the exchange by an au- thorized customer service or a skilled electrician. All electrical sockets should be fixed in an area that is protected against floods. Unsuitable electrical extension cables can be hazardous. Only use electrical extension cables outdoors which have been approved and labelled for this pur- pose and have an adequate cable cross-section. The mains plug and the coupling of an extension cable must be watertight and must never lie in water. Moreover, the coupling may never lie on the ground. The use of cable reels that ensure that the sockets are at least 60 mm above the ground is recommended. Do not use the power cord to carry/ transport the machine. To separate the machine from the mains, pull the plug and not the power cord. Do not scrape the power cord across sharp edges and ensure that it does not get pressed. Install the appliance in a safe position at a place protected against flooding. Do not operate the appliance continu- ously in rain or during humid weather. The voltage indicated on the type plate must correspond to the voltage of the electrical source. To avoid risks, all repairs and replace- ment of spare parts may only be carried out by the authorised customer service personnel. The water in the pump heats up if there is no water supply or the pressure side is closed and can cause injury if it flows out! The pump may be operated for maxi- mum 3 minutes in this operating status. Do not use this pump as an immersion pump. When using the pump near to pools, garden ponds or fountains, observe a minimum distance of 2m and safeguard the device against slipping into the wa- ter. Follow the rules for electrical safety of equipment: Only operate pumps near to pools, gar- den ponds or fountains, if they are equipped with an earth leakage circuit breaker with a nominal error current of max. 30 mA. It is not permitted to acti- vate the pump, if persons are in the pool or garden pond. Warranty Symbols in the operating instructions Safety instructions 19EN– 3 For safety reasons, we recommend that you operate the appliance only via a earth-leakage circuit breaker (max. 30 mA). The electrical connection of the system may only be performed by a qualified electrician. Please follow the respective national regulations! In Austria pumps to be used in swim- ming pools and garden ponds should be equipped with a fixed connection line according to ÖVE B/EN 60555 Part 1 to 3; power supply should be via a ÖVE- tested isolating transformer whereby the secondary nominal voltage should not exceed 230V. This appliance is not intended for use by persons with limited physical, senso- ry or mental capacities or lacking expe- rience and/or skills, unless such per- sons are accompanied and supervised by a person in charge of their safety or they have received precise instructions on the use of this appliance and have understood the resulting risks. Children may only use this appliance if they are over the age of 8 and super- vised by a person in charge of their safety, or if they have received instruc- tions on the use of this appliance and have understood the resulting risks. Children must not play with this appli- ance. Supervise children to prevent them from playing with the appliance. Cleaning and user maintenance must not be performed by children without supervision. Caution Water that has been delivered with this appliance is no drinking water! Caution Create stability for the appliance prior to any work on or with the appliance to pre- vent accidents or damage. The stability of the appliance is warranted when it is placed onto an even surface. With the ON/OFF switch the following three operating conditions can be switched: In the automatic mode the house & garden pumps automatically maintain the pressure in the system. If the pressure falls below approx. 0.13 MPa (1.3 bar), the pump is started. The pump is running as long as the flow rate > is approx. 60 l/h. If the withdrawal of water is completed, the pump goes into the stand- by mode after a short stopping time. The system is now under pressure. In case of water withdrawal and the resulting loss of pressure the pump starts again. The eco!logic models do not con- sume energy in the stand-by mode (input power = 0 W).

Tighten manually. Connect the vacuum-proof suction hose. Note In order to reduce the time required for suc- tion to start again, use a suction hose that is equipped with a backflow stop. This pre- vents the emptying of the suction hose after use (see accessories). If sandy water is to be delivered, we strong- ly recommend the use of an additional pre- filter (see optional accessories). Please in- stall this filter on the suction side of the pump, between the suction hose and the pump. Please use original Kärcher suction pipes, filter components and hose connections. When using components of other manufac- turers, malfunctions during drawing in the delivery fluid may arise, especially when using bayonet connection systems. Illustration Screw the connection adapter in the de- livery connection of the pump (outlet). Tighten manually. Connect delivery line. A garden hose with a minimum length of 5 m at a diameter of 3/4" or 15 m at a diameter of 1/2" is recommended. Illustration The 2-way adapter allows the simultaneous operation of two appliances (e.g. washing machine or sprinkler). It can be mounted in a way that either both outlets are used at the side or one outlet at the side and one outlet at the top. If only one outlet is used, the outlet that is not required can be closed by means of the accompanying closing cap. Illustration Unscrew the lid of the filler neck and fill in water up to the brim. Manually screw the lid all the way to the stop on the filler neck. Open existing shutoff valves in the pressure pipe. With a permanent installation the pump can be screwed onto a suitable surface. Illustration Pull out and turn the rubber feet on both sides of the casing. Reinsert the rubber feed into the cas- ing. Use suitable screws to screw it onto a level surface. In case of a permanent installation the in- stallation of a flexible component such as a flexible pressure compensating hose (see optional accessories) on the pressure side is recommended. This has the following benefits: More flexibility during set-up and instal- lation. Noise reduction, since no vibrations are transferred to pipes. In case of small leaks, the pump does not switch as often. Note To facilitate subsequent emptying and pressure release of the system, we recom- mend the installation of a stop-cock be- tween pump and pressure line. Description of the Appliance Preparing the Appliance Permanent installation 21EN– 5 (not included in delivery) By closing the shut-off valve when empty- ing the pump you can prevent water from escaping from the pressure line. Insert the mains plug into the socket. Switch on the appliance using the ON/ OFF switch. Optimum convenience with operation in the automatic mode. Illustration In order to reduce the suction time, lift the delivery hose approx. 1m. Wait till the pump sucks in and trans- ports water uniformly Note The ON/OFF switch can also be conveni- ently operated with your foot. Caution Dry running damages the pump. Do not leave the pump unattended dur- ing operation. Note In the automatic mode the pump switches off at a flow rate of < 60 l/h. 몇 Caution Lacking water supply is recognised by the appliance. If no water is drawn and deliv- ered within 4 minutes during start-up in the manual mode or within 1 minute in the au- tomatic mode, the pump shuts off. The LED "Error on the suction side" is illuminated on the display. Switch off the appliance using the On/ Off switch. Disconnect the main plug from the socket. Danger Turn off the appliance and remove the mains plug prior to any care and mainte- nance works. Open the connected shutoff valves to relief pressure and reclose them. The system is free of pressure. Rinse the pump after every use if you use to transport water with additives. Check pre-filter regularly for dirt. If it is vis- ibly dirty, proceed as follows: Illustration Unscrew the lid of the filling nozzle. Remove the pre-filter and the built in backflow valve and clean them under flowing water. Illustration When inserting the pre-filter (with check valve) in the filler neck, mind the correct installation position (notch). The appliance is maintenance free. Caution In order to prevent accidents or injuries, mind the weight of the appliance during transport (see technical data). Lift appliance by the carrying handle and carry it.

Prior to all work on the appliance, switch off the appliance and pull the power plug. Fault Cause Remedy Pump runs but does not transport Air in the pump see Chapter "Preparation" Fig. A to D and Chapter "Operation" Suction pipe blocked Switch off the pump, pull the mains plug and clean the intake area. Pre-filter is dirty Switch off the pump, pull the mains plug, allow the pump to cool down, clean intake area, prevent dry running. Remove the pre-filter and the check valve and clean it under running water, flush dirt residues from the bottom of the filler neck through the filler hole if necessary. Restart by switching the pump back on. Suction hose or connec- tion adapter not screwed in correctly or complete- ly. Check whether all seals have been in- stalled and are seated correctly prior to as- sembly. Manually tighten the suction hose and the connection adapter. Pump does not run or suddenly comes to a standstill during oper- ations Power supply interrupt-

Check fuses and electrical connections Pre-filter is dirty Remove the pre-filter and the check valve and clean it under running water, flush dirt residues from the bottom of the filler neck through the filler hole if necessary. The appliance is in the automatic mode. Pressure in the system >

The pump automatically switches back on as soon as the pressure in the system falls below 1.3 bar. Even after switching it off an back on the appliance does not start in the automatic mode if there is an internal pressure of more than 1.3 bar. 25EN– 9 Pump stops, LED "Er- ror on suction side" is illuminated. Failure on the suction side, pressure cannot build up Switch off the pump and pull the power plug. Remove the pre-filter and the check valve and clean it under running water, flush dirt residues from the bottom of the filler neck through the filler hole if necessary. Restart by switching the pump back on. Check connections on the suction side for leakage. Restart by switching the pump back on. Check if there is sufficient water in the suc- tion container (e.g. cistern). Flow rate very low -> the dry run protection has switched off the pump. Check if there is sufficient water in the suc- tion container (e.g. cistern). Automatic mode: Pump stops, LED "Er- ror on delivery side" is illuminated. Failure in the pressure line, the pump frequently switches on and off as a result of leakage. Check and correct the pressure line for leakages (dripping water tap). Restart by switching the pump back on. Error on delivery side. The pressure is too low after shutdown of the pump, the appliance starts again immediately and thus switches on and off frequently. There is no sufficient elastic volume avail- able on the delivery side. Use a garden hose with a minimum length of 5 m at a diameter of 3/4" or 15 m at a di- ameter of 1/2" for garden applications. Install a pressure compensating hose on the delivery side between the pump and the piping with permanent installation. Restart by switching the pump back on. Continuous opera- tion: Pump stops, LED "Er- ror on delivery side" is illuminated. The appliance works for at least four minutes, al- though the outlet on the delivery side (e.g. tap) is closed. Overheating protection switches off the appli- ance. Pull out the mains plug. Depressurise the appliance by opening the water outlet connected on the delivery side. Restart by switching the pump back on. Fault Cause Remedy 26 EN– 10 Pump transports is re- ducing or transported quantity is too low Suction pipe blocked Switch off the pump, pull the mains plug and clean the intake area. Pre-filter is dirty Remove the pre-filter and the check valve and clean it under running water, flush dirt residues from the bottom of the filler neck through the filler hole if necessary. Suction side is leaky Check the entire suction side for leaks The quantity transported by the pump depends on the transport height and the connected periphery Keep max. flow height, see technical data. If necessary, select a different hose diam- eter or hose length. Cross section on the de- livery side constricted, e.g. due to valve/ball valve that is not com- pletely opened. Completely open the valve/ball valve. Hose on the delivery side is kinked. Remove kinks from the hose.
