Fully open the gate valve on intake and keep the one on delivery almost closed.

Switch on and check that the direction of rotation is correct, as indicated in Fig. 1. If not, invert any two phase

leads, after having disconnected the pump from the power mains.
Once the hydraulic circuit has been completely filled with liquid, gradually open the delivery gate valve until its

maximum opening.
With the pump running, check the supply voltage at the motor terminals, which must not differ from the rated

value by +/- 5%.
With the unit at regular running speed, check that the current absorbed by the motor does not exceed the value

on the data plate.
