ESP(External Static Pressure) Diagram
The illustration below shows the external static pressure of the unit depending on the water flow and the pump setting.

If the pressure loss of total system is over 43(9 kW) or 20(16 kW)kPa, additional water pump should be installed in series.
Otherwise, the flow rate might decreased, causing insufficient heating or cooling.
When ESP is not enough, additional pump should be installed. In this case, install the PWM control external type pump (Heating
type) additionally.

Connection guide of additional pump

Case 1) INV. pump
Connect the PWM control external type pump to PWM terminal block and power cable to the external contact terminal.
The maximum number of additional pump installation is one inverter pumps (Input power 100W).
