4. OperationStarting the Pressure TankUnit:FILLRUNq0eqwFILLRUNqDANGER! Electric shock!v Before filling the pump, unplug the equipment fromthe mains.WARNING! Pump running dry!v Fill the pump to the overflow (approx. 2 to 3 l) withwater each time before the pump is switched on,so it does not run dry.1. Unscrew the cover 0 of the filter chamber by hand.2. Turn the rotary switch q to FILL.The integrated non-return valve will open.3. Open the air bleed w.4. Open any valves in the delivery line (watering accessories, waterstop, etc.) and drain off any residual water in the delivery hoseso that the air can escape during filling and priming.5. Slowly pour pumping medium (approx. 2 to 3 l) through the fillerneck e until water emerges from the air bleed w.6. Screw the filter chamber cover 0 closed again, turning by handuntil it stops.7. Close venting w and turn rotary switch q to RUN.8. Insert the mains plug into a 230 V mains socket.CAUTION! The pump will start immediately!Once the maximum pressure is reached the pump will switchoff automatically. When the pressure falls below the minimumvalue due to water being drawn off, the pump will switch on againautomatically.The maximum self-priming head of 8 m is only achieved if thepump is filled until it overflows from the filler connection e andthe delivery hose is held high enough during self-priming so thatno water can escape from the pump via the delivery hose. It isnot necessary to hold up the delivery hose if filled suction hoseswith backflow preventer are used.ECO switch:ECO MAXrIn order to save energy (up to 15 %), the cut-out pressure on thepump can, depending on the individual application, be regulatedbetween ECO and MAX (the pressure difference between ECOand MAX totals approx. 1 bar).v Turn the ECO rotary switch r to the required position.Note on the use of sprinklers: Depending on the flow rate of the sprinkler, an uneven wateringpattern may occur through the pump being switched on and offautomatically.16GB
