Before starting the electric pump check again electric and hydraulic connections and relevant rating. Check that all safety procedures and their good functioning have been activated. Check that the electric pump is correctly immerged and that the liquid level is allowing correct starting. Start the electric pump and check that the current does not exceed the plate value and that the supply voltage is within the foreseen limits. Adjust, when present, the correct rating of the protection relay according to the working current value, the relay must be rated 10% more than the electric pump plate value. If the unit does not start, do not insist. Identify the malfunction and repair the causes. We recommend you read the instruction manual of the Feka 2000 (also available in our DNA software) for useful information for use, maintenance and installation.
