To use the detergent dosing device, the detergent can must be fitted in the compartment provided on board the machine.
To do this, proceed as follows:
Open the compartment (pos. 1);
Take out the pipe (pos. 4) so it does not hinder can fitting:
Fit the can (pos. 2) as indicated in FIG.1. While performing this operation, do not remove the cap (pos. 3) of the can to
prevent detergent coming out.
Use low-foam liquid detergents or use a foam reducing product. Do not use
inflammable liquids.
For the percentages of detergent to be used and for safety precautions to be taken, see the instructions on the
pack.
Once the can has been fitted, remove the cap (pos. 3) and insert the pipe (pos. 4), making sure the filter reaches the
bottom so as to suction up all the detergent in the can.
Block the pipe (pos.4) by means of the cone (pos.5) inserting it in the can with a slight pressure (FIG.2).
DETERGENT DOSING SYSTEM WASHING
Once the washing operation has terminated, to keep the system in good working order and prevent scale, the system is
best washed as follows:
Remove the detergent can and insert another one filled only with water.
Make sure there is some water in the clean water tank.
Fit the detergent suction pipe (pos.4) and block it in position by means of the cone (pos.5).
With the machine stopped, turn the ignition key (pos.7) to POS.1 and press the red key (pos.6).
The metering pump will start to operate and suck up the water from the can and begin washing the entire dosing
system.
At the same time, the water pump will also begin operating, washing the pipes, the solenoid valve and the pump.
