○Contents of defect①Something wrong with hot water(Temperature is unstable)②Hot water(high temperature) does not come out③Water(low temperature) does not come out○Presumed cause①There is difference in the water supply or hot-water supply pressure,or the pressure of hot water supply is higher than the pressure of water supply.the pressure of water supply ≧ the pressure of hot water supply[ The difference should be in the range of 0.2Mpa ]②Pressure of water supply and hot water supply is high[ These two should be in the range between 0.1 and 0.4MPa ]○How to reactConnect a pressure reducing valve (Optional) on the upper side (mixer side)of the filtered check valve, then adjust the pressure.(It is recommended that water supply pressure and hot water supplypressure become the same pressure)Pressure reducingvalve(Optional)Check valvewith filterStop Valve3 Test water flow10●Detach the aerator core byusing the furnished wrench.CautionAlways test the water flow to preventaccidents during use.Shower outlet flow rateFiltered check valveFilterRemove and clean any dirttrapped within the filter pipeRemove and clean any dirt trapped within the shower head* Test the water flow and inspect the followingitems. The hot water may be slightly taintedat the start of the water flow test,however thisdoes not indicate any problem.* For safety reasons, the product's thermostatis designed so that the hot water does notexceed 53℃.(if the supply pressure is the same,water is 20℃ and hot water is 60℃)(1) Is there no water leaking from the pipe joints?The pipe joints may come loose during transportation,so check the joints within the basin thoroughly.(2) Are the hot water supply and water supply pressuresat the same, stable pressure?If the pressure is not the same, see "How to adjust faultytemperature regulation" below.(3) Can temperature be controlled properly?(4) Check that the shower outlet flow is sufficient,by the following as a guide for flow rate.Aeration shower head : Approximately 8 L/minSpa shower head (Aeration) : Approximately 8 L/min(shower) : Approximately 9 L/minShower headSpa shower headPackingAerator core O-ringAerator coreAerator shower headAfter the hot water becomes clear during the water flow test,always clean the filter (within the check valve)and shower head.Failure to do so can result in insufficient flow rate and faulty temperature regulation.Cleaning-How to adjust faulty temperature regulation-
