User manual EINHELL HWA 1300 NIRO

[. . . ] The manufacturer's warranty shall lapse if the pump is damaged due to it being allowed to run dry. Please read the instructions for use very carefully and observe the information they contain. By referring to these instructions, familiarize yourself with the appliance, learn how to use it correctly, and note the safety precautions to be taken. Take the appropriate steps to ensure that children have no access to the appliance. [. . . ] Mount the flow switch on the pressure connection of the pump and then tighten the union nut. 3/4" plastic hose with spiral reinforcement) directly or with a threaded nipple to the suction connection (1" IG) of the pump (see Figure 1). A non-return valve should be installed in the suction line in case the suction valve cannot be used. Lay the suction line so that it ascends from the water pick-up point to the pump. Take care not to lay the suction line above the height of the pump air bubbles in the suction line will obstruct and prolong the priming operation. Attach the suction and delivery lines so that they do not exert any mechanical pressure on the pump. The suction valve should be deep enough in the water so that the pump will not run dry when the level of the water drops. A leak in the suction line will cause air to get into the line and prevent the pump from drawing in water. Basically, we recommend the use of a prefilter and an intake set with an intake hose, an intake strainer and check valve in order to prevent long repriming times and any unnecessary damage to the pump caused by stones and hard foreign bodies. A 1/2" pressure hose can also be used with the appropriate screw connections, of course, but this will reduce the delivery rate. Operating pressure: Water temperature: 230 V ~ 50 Hz 10 bar 60°C After temporary power failures the water management system will switch on again automatically when the power returns. in the event of faults such as water shortage , clogging of the supply line etc. The red lamp , , Failure" will light up and trigger a fault message with Emergency Off of the pump. When you have remedied the trouble you must keep the Reset button pressed until the unit returns to its normal operating state. All the operating modes are indicated by LEDs on the front of the unit. As soon as the unit is connected to the electric supply the green indicator lamp , , Power On" lights up and the yellow lamp , , Pump On" also lights up. The pump remains on for several seconds in order to fill the supply system with water and build up the necessary pressure. If the pump does not run long enough to draw in the water, the red lamp , , Failure" lights up. In this case keep the , , Restart" button pressed and wait again, with the tap open, for the red lamp to go out. If the priming takes a long time, you will need to top up again with water. [. . . ] After long stoppages, make sure the rotor turns correctly by briefly switching the pump on and off. If the pump becomes blocked, connect the pressure line to the water line and remove the intake hose. Motor fails to start up Causes No mains voltage Pump rotor blocked -thermostat switched off No intake Causes Intake valve not in water Pump chamber without water connection Air in intake line air-tight Intake valve leaks Strainer (intake valve) blocked Max. Suction height exceeded Inadequate delivery rate Causes Suction height too high Strainer dirty Water level falling rapidly Pump performance diminishedby contaminants part Thermostat switches pump off Causes Motor overloaded - friction caused by foreign substances too high Warning!
