[. . . ] Take the appropriate precautions to keep children away from the device. General safety advice / Preparing for use Do not use the device if there are people in the water. Ensure that the electrical plug-in connector is positioned where it cannot be reached by the water. Do not use the mains lead or the hose for any purpose for which it was not intended, e. [. . . ] Suspend the device from the handle 1 or stand it on the bottom or supporting surface. Loop the rope 12 around the handle 1 and fasten it with a double knot. Dirt and sand may build up over time on the bottom or supporting surface, which could damage the pump. If the water level in the chamber is too low, any sludge present could quickly dry out and prevent the pump from starting. This mechanism allows any air to escape from the device as soon as the device is submerged in water. If the submersible pump is not completely submerged in water during operation, then water may escape from the air bleed mechanism 2 . Do not screw off the air bleed mechanism 2 , otherwise damage to the device may occur. Note: The float switch 8 is set up to allow the pump to be used immediately. In the case of a permanent installation, the float switch 8 must be checked regularly (at least every three months) to see that it is working properly. The on and off switching point of the float switch 8 can be set by altering the position of the float switch 8 in the float switch pivot clip 9 (see Fig. The following principles apply here: The longer the length of the cable of the float switch 8 from the float switch pivot clip 9 to the float, the higher the on and off switching point will be. Position the float switch 8 so that the "ON" and "OFF" switch point level is achieved easily and with little force. Stand the pump in water in a vessel, then carefully raise the float switch 8 by hand and then let it fall again. To bring the submersible pump into use, plug the mains plug into a suitable mains socket. Depending on the set switch point level and the water level, the float switch 8 switches automatically on or off as appropriate. Note: Ensure that the distance between the float switch head and the float switch pivot clip 9 is not too short. When making the setting ensure that float switch 8 does not come into contact with the bottom or supporting surface before the pump switches off. Otherwise there is the risk that the pump may run dry and become damaged. Note: The water can be pumped out through a fixed pipe or a flexible hose. The hose may block if the particle size is greater than 35 mm, or 19 mm with the reducer fitted, (see the section on "Maintenance and cleaning"). Pull a hose over the reducer 10 and fix it in place with a hose clamp. Or you can use a Before you carry out any work on the device, always pull the mains plug out of the mains socket. [. . . ] Note: If the impeller 13 becomes dirty or blocked, you can clean it using the pump outlet 4 or by screwing off the base plate 5 (see Fig. Remove the 3 screws from the underside of the pump housing 3 and take off the base plate 5 . Note: Any other tasks on the pump, in particular opening the pump, must be carried out by an electrician or similar expert.
