Before starting up you must fill the system with water and bleed the air. Bleed the residual air from the pump body through the bleeding cock provided until only water comes out. This ensures that the mechanical seal is well lubricated and that the pump immediately starts to work regularly. Dry operation, even for brief periods, causes irreparable damage to the mechanical seal. Switch on the power and, on three-phase versions, check that the motor is turning in the right direction, that is clockwise when viewed from the fan side. Otherwise exchange two phases leads, after having disconnected the pump from the mains. 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. We recommend you read the instruction manual of the KLM, KLP / DKLM, DKLP (also available in our DNA software) for all information.
