4.1 Water Pump Performance Graph
The water pump is three speed-adjustable (Maximum / Medium / Minimum), so it may be required to change
default water pump speed in case of noise by water flow. In most case, however, it is strongly recommended to
set speed as Maximum.
* To secure enough water flow rate, do not set water pump speed as "Min."
