Starting : Illustration 2.1
Be sure that the pump is correctly primed.
Connect the EDWC-3 / EDWC FR-3 to the electric supply. The tension LED will lit (Power
On). Then gently open one tap. The pump starts working automatically and within a
period of 20-25 seconds will reach approximately the maximum pressure provided by
the pump.
During its working the corresponding LED (Pump On) will be on. Close the tap. After
4-5 seconds the pump will stop. The tension LED (Power On)will be the only one to
remain on. Any problem after this procedure will be due to a defective pump priming.
