Page 9: Hydraulic Connections
HYDRAULIC CONNECTIONS Check that the suction line does not exceed the maximum height of 1.5 m from the tank bottom. Unscrew the pipe-wrench nut and remove the two protective caps from fittings (in the case a pump head needs to be removed, it is recommended to reuse the protective caps, to prevent any leakage from the pump body). -
Page 10: Injection Line
Injection Line (also see drawing on the previous page) 1. Unscrew the fixing nut of the head fitting (located on the top of the pump head) and remove the protective cap. 2. Cut the white, semi-rigid, PE tube. 3. Insert the pipe-wrench and tube-press on the PE tube. 4. -
Page 11: Electrical Connections
ELECTRICAL CONNECTIONS The EF267 unit comes prewired and complete with power cable (with plug upon request). Standard power supply: 230 V∼, 50 Hz, monophasic. Carefully follow all the rules of electrical safety. Before starting the unit, check that all electrical and plumbing connections have been properly executed. -
Page 12: Internal Connections (For Technical Personnel Only)
INTERNAL CONNECTIONS (for technical personnel only) The unit is provided internally prewired, and all connections of normal use (power supply, measurement sensors and level sensors) are available externally via cable or connector. However, if you need to operate on the electronic boards or replace blown fuses, refer to the diagram below. -
Page 13: Start-Up
START-UP At start-up the microcontroller displays for a couple of seconds information about the firmware (type / version), then shows the two measures flashing for all the start-up delay time (if set) and then starts operating accordingly with the configured working mode. VISUALIZATIONS During normal operations, the display shows the two measured values on the top line, while the bottom row displays the status of the two pumps. -
