For the first use after installation, due to there's no water within the tank, first the citywater inlet valve and mixing valve must be opened. Close the mixing valve when waterflows out continuously from the showerhead or other outlets (the tank is full). Checkconnections are free of water leakage, and insert the power plug.Turn the knob to set your desired water heating temperature, which can be steplesschanged between cold water inlet temperature and 75 . In heating mode, heating lampis lighted on. Normally the knob shall be positioned at highest temperature. Thismachine has a thermostat function, which automatically switches off the water heaterwhen temperature reaches the setting value, and switch on again when watertemperature decreases to certain value.City water pressure 0.75 MPa will cause much water flowing out from safety valvepressure relief vent. This is due to too big water pressure. Please ask after-salesservice for correction.To avoid causing machine troubles, do not connect power before tank is full of water.Adjust a suitable temperature before use, for water temperature above 50 may burnyour skin.This product is closed water heater, which can supply hot water through pipe connectionto several points like bathroom (bathtub, washbasin, showerhead) and kitchen.Provided hot water quantity can meet use demand, temperature setting shall be possiblylow. It can minimize heat dissipation, high-temperature corrosion and sedimentation,ensuring a longer service life.Regularly ask servicemen to make safety inspection, remove sediment on heatingelements, and check consumption of anode bar. Too much consumed anode bar shall bereplaced.Heating adjustment can be made flexibly all year round adapting to climate changes. Inlong-term out-of-use or maintenance, you can close city water pipe valve and set themixing valve to the highest water temperature rate after opening the safety valve handle.Move up safety valve handle to drain the tank. To avoid injury, before next use, it issuggested to first open hot water valve before switching on the water heater, exhaustinggas possibly retained in the pipeline. In this case, no smoke or fire is permitted near theopen valve. Carefully check and confirm all parts are in good condition.This water heater shall only be repaired and maintained by qualifiedservicemen. Improper maintenance may cause severe injury or damage.Before opening or repairing water heater, please do pull out the power plug.External Cleaning: Disconnect power supply before cleaning. Gently wipe with wetcloth dipped with a little of mild detergent. Do not use gasoline or other solvents.Finally dry with dry cloth. Keep water heater dry. Do not use cleansers containinggrinding agent (e.g. toothpaste), acids, chemical solvents (e.g. alcohol) or polishers toclean.LN E HLEHEBTMTL: Brown wireN: Blue wireMT:High temperature limiterBT: ThermostatHL: Heating indicatorEH: Heating elementE:Yellow/green wire(Fig. 1)1.2.3.4.5.6.Statement:Note: Before asking for service, please refer to troubleshooting section to resolve easyproblems.Remarks:the permitted error limit of above parameters is 10%.ABCDEFGHot water outletCold water inletHeating elementEnamel tankWall-mounting bracketMagnesium anode rodDrain holeFront View Cutaway View Bottom ViewDE ECa1e1C1d1f1b1A BF GModel Volume NetWeight a1 b1 c1 d1 e1 f1DimensionsElectric Circuit DiagramOperation InstructionsAttentions in OperationCleaning and Maintenance
