- Check that the injection valve is not clogged
- Check the suction and head valves

EF110_r1.0 – 10/2019
Set the pump for continuous operation (P4 = 1), but stop it with the ON/OFF key.
Insert the left fitting onto the new tube, in its place, while paying attention that the
rounded part is positioned inwards.
Then turn the roller-holder clockwise, so that the tube is inserted in its seat.
Insert the right fitting in its seat and secure the transparent cover by screwing the
two front screws.
Connect the suction and injection tubes, then set correctly the parameter P4.
