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
• To secure enough water flow rate, do not set water pump capacity as Minimum.
It can lead unexpected flow rate error CH14.

Pressure Drop

When installing the product, install additional pump in consideration of the pressure loss and
pump performance.
