The product manual available here on our site or here in our DNA software provides useful information for the usage and maintenance of this product. Also we suggest you to read the MCE/P inverter manual. starting up, check that the pump is properly primed; fill it completely with clean water by means of the hole provided after having removed the filler cap on the discharge body. This ensures that the mechanical seal is well lubricated and that the pump immediately starts to work regularly. The filler cap must then be put back in place. Dry operation causes irreparable damage to the mechanical seal and the stuffing box seal. Fully open the gate valve on intake and keep the one on delivery almost closed. Switch on the power and check that the motor is turning in the right direction, that is clockwise when viewed from the fan side, (indicated also by the arrow on the fan cover). Otherwise invert any two phases leads, after having disconnected the pump from the 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%.

The direction of rotation must be cheeked only in three-phase pumps (then pumps powered at 400 volts). In single-phase pumps (230 volts) the motor always rotates in the correct direction. We always recommend checking the product manual here and here in our DNA software. The direction of rotation must be clockwise as shown:
