ECOFLEX™ SYSTEM DRAINING (For Adfinity™ X20R, X20D - X20C - X24D)

3. Turn on the machine by turning the ignition key (80) to "I".

7. Collect the detergent remained on the floor.
8. Turn the ignition key (80) to "0".
9. Grasp the handle (41) and carefully lift the tank (40), then check that the hose (48) is empty, otherwise perform steps 3 to 9
again.
NOTE
The draining cycle lasts about 30 seconds, then the vacuum function automatically turns on, which allows to remove the
detergent remained. The draining cycle can also be performed with the detergent tank (45) full of water, thus cleaning the
system thoroughly.
It is advisable to perform the draining cycle when the EcoFlex™ system is really dirty/encrusted because the machine
has not been used/cleaned for a long time.
The draining cycle can be performed also to quickly fill the detergent supply hose when the tank (45) is full but the
system is still empty.
If necessary, the draining cycle can be repeatedly performed.
