Feature:1. The intelligent booster pump can provide high and low pressure protection, avoiding the problems of rusty jamming and freezing of the pump head in winter.2. The pump is made of accuracy machining and casting, and it runs smoothly. The ball bearings can reduce wear and have a longer service life.3. Water tower replenishment can be set to start regularly, and automatically stop when the water is full to make sure that the water tower is full.4. The selfpriming booster pump adopts shielding noise reduction technology to make sure quiet operation and quietness.5. Enjoy six protections, namely overheating protection, overload protection, phase lack protection, water shortage protection, jam protection and leakage protection.Specification:Item Type: Self-Priming PumpMaterial: 45 Steel + CopperApplications: Tap water pressurization, well water pumping, high floor pressurization, water heater pressurizationVoltage: AC 220-240VPower: 400WFrequency: 50HzCurrent: 3.2ASpeed: 2860r/minRated Flow: 1.0m/hMaximum Flow: 2.0m/hRated Lift: Approx. 15m / 49.2ftMaximum Lift: Approx. 35m / 114.8ftMaximum Self-Priming Height: Approx. 8m / 26.2ftSwitch Start Pressure: 1.2kg/cFemale Thread Diameter: G1in(Approx. 30.5mm / 1.2in)Applicable Floors: Fourth floor and belowNumber of Faucets: 3-5PcsWorking Temperature: 0~100PH Value: 6.5-8.5Function Description:Function Description 1 Boot Delay Power-on delay start.2 Self-LearningSelf-learning for the first time, turn off the faucet, and the learning will be completed automatically in 10 seconds or 1-2 minutes. The starting pressure defaults to 70% of the highest head.3 Control Mode Learning After learning, it will start and stop automatically, the light flashes when running, and the running light is always on when it stops.4 Superimposed Pressure Learning When the water pressure of the tap water changes and fluctuates, no matter whether the water pressure becomes higher or lower, the control water pressure changer will automatically learn and complete the adjustment.5 Start Frequently If the small water flow starts frequently, the controller will automatically adjust the parameters to avoid frequent starting to protect the motor, and the small water flow experience is better.6 Water Shortage Protection In the case of water shortage, the pump will automatically identify and enter the protection mode after running for a period of time.7 Anti-Blocking Start 10 seconds in 24 hours.8 Frost Protection If the temperature is lower than 3, it will work for a while and stop at 8.9 High Temperature Protection The temperature is higher than 80 forced shutdown protection.Code Description: Code MeaningProcessing Method 1E-FWater shortage protectionOverpressure or abnormal sensor2E-EPressure sensor abnormalPower off and restart3E-HOverpressure or abnormal sensorReplace the sensorIndicator Light Description: Indicator Status Significance 1 Green light (running light) flashes The pump is working2 Green light (running light) is always on Standby3 Red light (protection light) is always on Normal shutdown or protection.Package List:1 x Automatic Self-Priming Pump1 x Filter
