Before filling the pump through the filling hole you must first partially unscrew the drainage pin/cap (when filling just unscrew it by 3 or 4 turns) without forcing it.

• After having removed the cap, fill the pump slowly through the filling hole so as to discharge any air pockets present inside.
• Before starting the pump, close the filling cap and screw the drainage pin/cap all the way, without forcing it.
• Vent by means of the screw on the part opposite the filling cap
• 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. 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.
