Pressure Drop
Water pump Capacity
The water pump us variable type which is capable to change flow rate, so it may be required to
change default water pump capacity in case of noise by water flow. In most case, however, it is
strongly recommended to set capacity as Maximum.
NOTE
• To secure enough water flow rate, do not set water pump capacity as Minimum.
It can lead unexpected flow rate error CH14.
NOTE
When installing the product, install additional pump in consideration of the pressure loss and
pump performance.
If flow-rate is low, overloading of product can occur.
