10. Hydraulic Performance
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.

For GRUNDFOS Water Pump
For OH SUNG Water Pump
Note
• To secure enough water flow rate, do not set water pump capacity as Minimum.
It can lead unexpected flow rate error CH14.
• 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.
