7.1 Water Pump Capacity

Water volume and pump capacity

The water pump is BLDC, so it may be required to change default water pump speed in case of noise by waterflow.
In most case, however, it is strongly recommended to set speed as Maximum.
Notice
Water pump speed : To secure enough water flow rate, do not set water pump speed as "Min."
It can lead unexpected flow rate error CH14.
