Eureka E50 - Periodic Servicing; Draining and Cleaning the Recovery Tank

 Gradually open the valve by turning the device pos 3 and dosing the water leakage to avoid splashing;
 Once the tank has been emptied, remove the cover pos.4 and carefully wash the inside with water.
Wash well to make sure all residues are removed, even the smallest ones (sand) and also clean the closing valve well
so it is always in good operating condition;
 Screw off the anti-foam device pos. 5 and wash the float pos. 6 without removing it from the machine;
 Remove and wash the curved sleeve pos. 7 removing any dirt deposits;
 Wash the squeegee vacuum pipe. To perform this operation, remove the pipe pos. 9 from the squeegee, fit the water
pipe in the duct pos. 8 and allow water to flow. This will avoid the formation of scale deposits inside the pipe and
vacuum will always be perfect;
 After cleaning, fit the anti-foam device pos. 5 back on together with the curved sleeve pos. 7. Close the valve pos. 3,
fit the cap pos. 2 back on and return the drain pipe pos. 1 to its housing. Fit the cover pos. 4 back on and refit the
squeegee vacuum pipe pos. 9 making it form the anti-drip loop;
 During tank cleaning avoid any water spraying onto the control panel (pos. 10).
