This electric water heater must have a safe and reliable grounding device.2. This machine must be installed with a safety valve at the water inlet.3, must be filled with water before powering up, when adding water should open the water inlet and outlet simultaneously,after fill up the water,it will flow out from the water outlet.4. The water inlet and outlet of the water heater cannot be closed at the sametime.5. It should be cleaned once for half a year.Method: first close the tap water valve, then unscrew the drain port (be careful to avoid hot water) and then open the water outlet valve, the water in the machine will flow out from the drain outlet. After emptying, open the tap water valve and rinse it several times until the water that flows out is free of impurities.Daily mainternance:1, Always pay attention to the pipe joints with or without water leakage, if any, timely treatment.2. Regularly (one week) check whether the leakage test plug of the leakage protection plug power cord  "test power off " button can be operated.3. Always observe whether the safety valve can be properly relieved.4.  Always  check  if  the  grounding  of  the   power  socket  is  firm  and  meet  the   power  supply requirements.5, Rigorous wethand plugged in the power plug, the power plug should be unplugged when not in use for a long time.6. Due to the different water quality and hardness of different areas, the water heater should be drained regularly to discharge the sediment at the bottom of the tank. To empty the water heater, first close the tap water valve, then unscrew the drain port (be careful to avoid hot water), then open the water outlet valve, the water in the machine will flow out from the drain outlet. After emptying, open the tap water valve and rinse it several times until the water that flows out is free of impurities.7. The safety valve should not be replaced at will. Only the original parts can be used. The pressure of the safety valve should not be adjusted by itself. At least once a month, the safety valve handle is swayed (unscrew the fixing screw before shaking) to see if there is water Discharge, if it can not be discharged, notify the manufacturer or the manufacturer of the service point to repair.Common fault and approach:  FaultphenomenonCause AnalysisApproachWater   discharging is cold water(The work indicator is off)1. The  reset  button on the  plug or the power switch is not pressed2. Power fuse off or air switch jumpor leakage protection switch action3. Power supply line blackout4. Poor contact in the power outlet   5.  The  lowest  temperature  co
