Connection release leverConnecting pedalAfter the test water flow is finished, turn the mixer handle back to the initial position to stop water.Release the connection of the upper unit and the floor unit.Pull the connection release lever depressing the detaching pedal slowly.The connecting pedal return to the initial position.The connection is released.The piping connection part has the mechanism that the valve blocksthe flow path after the connection is released.However, a tiny amount of water droplets may fall into the floor unit,which does not cause a problem. Use it as it is.For Test Water Flow, check the followings:The hot water may be slightly tainted at the start of the test water flow, however this does not indicate any problem.For safety reasons, the product's thermostat is designed so that the hot water does not exceed 49˚C.(If the supply pressure is the same, water is 20˚C and hot water is 60˚C.)1. Check for leakage from the piping connection part and the floor unit piping connection part.The connection may get loosen during transportation.Closely check the piping connection part inside the upper unit.2. Check the shower outlet flow rate, refer to the following standards.YUME shower head(Aerator): Approximately 9.5 L/min: Approximately 8.0 L/minSide Wash BasinYUME shower head :(Aerator): Approximately 8.5 L/min: Approximately 7.5 L/minShower outlet flow ratehot water supply pressure, water supply pressure: 0.1 MPa eachShower outlet temperature : 40˚C623Test Water FlowNoteCAUTION● Always test the water flow to prevent accidents during use.● When the product is shipped, the faucet handle (on the basin) is not tightly closed up.If you open the stop valve while the upper unit is connected, water may come out from the shower head.Test the water flow.
