*1 Volume of sanitary water circuit is not included in this value.
*2 If the water flow rate exceeds maximum, the flow speed will be greater than 1.5 m/s, which could corrode the pipes.
*3 If the water flow is less than the minimum, the flow error will be activated.
*4 The environment must be frost-free.
