Product Details:
Special warning:
1. 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:

Fault phenomenon	Cause Analysis	Approach
Water discharging is cold water (The work indicator is off)	1. The reset button on the plug or the power switch is not pressed 2. Power fuse off or air switch jump or leakage protection switch action 3. Power supply line blackout 4. Poor contact in the power outlet 5. The lowest temperature control state of the thermostat 6. Thermostat, thermal circuit breaker is bad	1. Press thereset button or power switch 2. Replace the fuse (close the air switch), reset the leakage protection switch 3. Power supply to be powered 4. Replace the power outlet 5. Adjust the thermostat to the "high temperature" file 6. Replace the thermostat, thermal circuit breaker
Water is cold water (The work indicator is on)	1. Heating time is not enough 2. Electric heating tube burned out 3. Mixing valve failure The patch cord is loose and the contact is poor.	Waiting for heating 2. Replace the electric heating tube 3. Replace the mixing valve Replacement connector
Hot water outlet does not produce water	1. Tap water to stop water 2. The water pressure is too low 3. The tap water inlet valve is not open 4. Mixing valve failure Inlet and outlet pipe failure	1. Waiting for tap water supply 2. Re-use when the water pressure rises 3. Open the inlet valve 4. Replace the mixing valve 5. Check the replacement of the inlet and outlet pipe
Remaining current protector reset button cannot be reset	Leakage 2. Plug damage	1. Check for leakage faults: power cord, internal connection line, thermostat, over-temperature protector, electric heating tube, etc. 2. Replace the plug or professional repair
Warning light on	1. Ground wire is charged 2. Machine leakage	Stop using, notify the professional to repair
Fault code table	E2 dry burning protection E3 temperature sensor failure E4 over temperature protection	Power off after adding water Replace the temperature sensor Replace the board
