EDS - ECO DOSAGE SOLUTION DRAINING

(For machines with EDS - ECO Dosage Solution)
1. Clean the detergent tank according to the procedure shown in the previous paragraph. To remove the detergent remained
in the hoses and in the pump, perform the following procedure.
2. Grasp the handle (41) and carefully lower the tank (40).
3. Turn on the machine by turning the ignition key (80) to "I" position.
4. Turn on the EDS - ECO Dosage Solution by pressing the switch (77). Check that the switch warning light (78) turns on.
5. Simultaneously press the switches (77 and 82a), until the switch warning light (78) starts flashing (after about 5 seconds).
6. Release the switches and wait for the warning light (78) to stop flashing and for the vacuum system to turn on.
7. Collect the detergent remained on the floor.
8. Turn the ignition key (80) to "0" position.
9. Grasp the handle (41) and carefully lift the tank (40), then check that the hose (48) is empty, otherwise perform the 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 solution 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 EDS - ECO Dosage Solution 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 suction hose when the tank (45) is full
but the system is still empty.
If necessary, the draining cycle can be repeatedly performed.
