WATER PIPING
Pressure Drop
Water pump Capacity
The water pump is 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
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
